1. INTRODUCTIONAny structure, building or system needs maintenance and rehabilitation which are of

course costly. Highways and roads are also not an exception. From the very past, the

construction, extension, maintenance and operating costs of highways, roads, bridges and

tunnels were collected directly or indirectly. In the older indirect method, the expenses are

compensated either by tax payment on fuel or by budget allocation from the national income.

The shortcoming of this method is that a number of tax payers, who do not use some of the

roads and carriageways, have to pay extra money. However, in the other system, called direct

method, the tolls are taken directly from the drivers passing that road or street. The other

three main reasons why tolling, or road pricing, is implemented are listed below. [1]

1. Finance/Revenue Generation: To recoup the costs of building, operating andmaintaining the facility. Road pricing is becoming a more appealing means of funding

transportation. Moreover, toll financing allows projects to be built sooner instead of

waiting for tax revenues to accumulate.[1]

2. Demand Management: To moderate the growth in demand on the transportationsystem, and to encourage more use of public transportation and carpooling. For

example, vehicles are charged to enter inner London, England, as a way of regulating

the demand in the region.[1]

3. Congestion Management: To place a price on limited roadway space in proportionto demand. In this application the toll increases with the level of congestion. In the

absence of such pricing, drivers do not appreciate the costs they impose on others as a

result of the congestion they cause. [1]

2. CLOSED, OPEN AND ALL OPEN-ETC ROAD TOLLING:Three systems of toll roads exist: open (with mainline barrier toll plazas); closed (with

entry/exit tolls) and all-electronic toll collection (no toll booths, only electronic toll collection

gantries at entrances and exits or at strategic locations on the mainline of the road).

On an open toll system, all vehicles stop at various locations along the highway to pay a

toll. While this may save money from the lack of need to construct tolls at every exit, it can

cause traffic congestion, and drivers may be able to avoid tolls by exiting and re-entering the

highway. [2]

With a closed system, vehicles collect a ticket when entering the highway. In some cases,

the ticket displays the toll to be paid on exit. Upon exit, the driver must pay the amount listed

for the given exit. Should the ticket be lost, a driver must typically pay the maximum amount

possible for travel on that highway. Short toll roads with no intermediate entries or exits may

have only one toll plaza at one end, with motorists traveling in either direction paying a flat

fee either when they enter or when they exit the toll road. In a variant of the closed toll

system, mainline barriers are present at the two endpoints of the toll road, and each

interchange has a ramp toll that is paid upon exit or entry. In this case, a motorist pays a flat

fee at the ramp toll and another flat fee at the end of the toll road; no ticket is necessary.

In an all-electronic system no cash toll collection takes place, tolls are usually collected

with the use of a transponder mounted on the windshield of each vehicle, which is linked to a

customer account which is debited for each use of the toll road. On some roads automobiles

and light trucks without transponders are permitted to use the road (though trucks with a

gross vehicle weight over 5,000 kilograms must have a transponder)- a bill for the toll due is

then sent to the registered owner of the vehicle by mail; by contrast, some tollways require all

vehicles to be equipped with a transponder. [2]

Modern toll roads often use a combination of the three, with various entry and exit tolls

supplemented by occasional mainline tolls. Open Road Tolling (ORT), with all-electronic toll

collection, is now the preferred practice, being more efficient, environmentally friendly, and

safer than manual toll collection. [2]

3. EVOLUTION AND FUTURE OF TOLLING:Roadway tolling is expected to become more pervasive over time. Four stages are

envisioned beginning with corridor tolling and cordon tolling, then area-wide or vehicle-

miles-travelled (VMT) tolling, and ultimately an integrated system management strategy

(Deloitte Research Public Sector Study, 2003). Each stage improves system efficiency overthe previous one, but also has higher complexity. Each stage also requires certain conditions

before implementation. Only the first two strategies, corridor tolling and cordon tolling, have

been widely implemented, with ETC being a necessity to move to the next two stages. The

third stage is now being pilot tested in a few areas, while the final stage, an integrated system,

lies in the future. [1]

Corridor Tolling: This is the most common form of tolling, in which a driver pays a fee to

use a specific stretch of roadway or bridge. High Occupancy Toll (HOT) lanes are designated

for multi-passengers, but single-occupant vehicles can use if they pay a toll. The primary

objective of the toll is to repay the cost of building and operating the facility. Complexity canbe as low as having the driver stop and pay cash on entry, although most systems are

implementing Open Road Tolling. However, the corridor is likely to be underused compared

to alternative non-tolled routes and may not relieve congestion in a region. The road must be

exclusive to those who pay, otherwise users do not feel compelled to pay and the program

may not earn adequate revenue. [1]

Cordon Tolling: This is a charge for entering a specific area. The primary objective is to

reduce the number of vehicles entering. Every entry point must be equipped with means of

identifying vehicles and ensuring that they pay, have paid, or will pay. To be an effective

strategy, the public must be convinced that benefits (improved mobility, lower pollution, etc.)will be realized fairly quickly. An efficient public transportation system is essential for this

strategy to be effective. This is implemented in London City to avoid traffic and pollution

problems during daytime. [1]

Area-wide Mileage Tolling: This is a mechanism whereby vehicles are charged based on

VMTa road user fee. An example of this system is the German truck toll, in which all

trucks are required to pay tolls based on the distance travelled inside Germany. In some

respects this strategy is analogous to the U.S. gas tax, in that, theoretically, each vehicle pays

based on miles driven. The primary objective is to generate revenue for the transportation

system and, to a lesser degree, to regulate the amount of driving. The complexity of distance-based tolling is relatively high and requires uniform application area-wide, as well as

interoperability across borders. [1]

Integrated System Management: In this visionary concept, demand for transportation

would be managed through information: users would have a choice of modes and routes and

an array of ways to pay for a trip. The charge would incentivize the most efficient transport

choice and the market would drive the provision of capacity. Highly complex systems, such

as roadside-vehicle-traveller communications would be required, but system usage is

expected to be highly efficient. Required conditions include market flexibility and access to

information. [1]

4. Electronic Toll CollectionElectronic Toll Collection (ETC) is a technology that allows for electronic payment of

tolls. An ETC system is able to determine if a vehicle is registered in a toll payment

program, alerts enforcers of toll payment violations, and debits the participating account. Toll

charges are generally based on mileage, maintenance requirements, or congestion levels. In

recent years most ETC systems in general were based on using radio devices in vehicles thatwould use proprietary protocols to identify a vehicle as it passed under a gantry over the

roadway. [3]

However, not all toll way users are equipped with the necessary on-board devices to

enable the electronic toll collection. And unless 100 percent take up of ETC by the motoring

public is achieved, manual collection will always be required for those toll way users who do

not have the on-board equipment. Deciding on the best way to allocate ETC and Manual

collection service types among available toll plaza lanes requires an appropriate framework.

Using a cost-benefit analysis approach, the main basis for selecting the service type allocation

regime would be the one that which minimizes the cost to operator or users separately or thatwhich minimizes the combined costs to the operator and the users (which could be treated as

social combination). [3]

The total cost of toll collection facility operations includes initial expenditures to

establish the structures and support facilities hire and train personnel, among others. ETC

transactions can be performed while vehicles travel at near highway cruising speed.

Electronic Toll Collection (ETC) is used in cordoned urban areas, over bridges, in tunnels, in

High Occupancy Toll (HOT) lanes, on toll roads, or through turnpikes. ETC is fast becoming

a globally accepted method of toll collection, a trend greatly aided by the growth of

interoperable ETC technologies. [3]

5. BENEFITS OF ETC

The benefits because of ETC for the driver, toll operator and vehicle owners are listed

below.

Some of the benefits for drivers include [4]:

fewer and shorter queues at toll plazas by increasing toll booth service rates; faster and more efficient servicethe customer does not need to stop or have toll fees on

hand;

the ability to pay by keeping a balance on the customers account or charging a registeredcredit card;

Mailed toll statementsthe customer no longer has to request a receipt. Reduced accident rates/ improved safety because of less slow-and-go driving.Some of the benefits for toll operators include[4]:

lowered toll collection costs; better audit control by centralized user accounts; Expanded capacity without being required to build more infrastructure.For everyone, some of the benefits of ETC include [4]:

fuel savings; reduced mobile emissions by reducing or eliminating deceleration, waiting times, and

acceleration;

Possible reduced drain on public monies, if the system is more self-sustaining or if thesystem was built/run via a public-private partnership arrangement.

6. COMPONENTS OF ETC

An ETC system typically includes four components [5]:

Automatic Vehicle Identification (AVI)

Automatic Vehicle Classification (AVC)

Transaction Processing

Violation Enforcement

6.1Automated Vehicle Identification

Figure: Ontario's Highway 407- use ofautomatic number plate recognition

Automated vehicle identification (AVI) is the process of determining the identity of a

vehicle subject to tolls. The majority of toll facilities record the passage of vehicles through a

limited number of toll gates. At such facilities, the task is then to identify the vehicle in the

gate area. [5]

Some early AVI systems used barcodes affixed to each vehicle, to be read optically at the

toll booth. Optical systems proved to have poor reading reliability, especially when faced

with inclement weather and dirty vehicles. [5]

Most current AVI systems rely on radio-frequency identification, where an antenna at thetoll gate communicates with a transponder on the vehicle via Dedicated Short Range

Communications (DSRC). RFID tags have proved to have excellent accuracy, and can be

read at highway speeds. The major disadvantage is the cost of equipping each vehicle with a

transponder, which can be a major start-up expense, if paid by the toll agency, or a strong

customer deterrent, if paid by the customer. [5]

To avoid the need for transponders, some systems, notably the 407 ETR (Electronic Toll

Route) near Toronto, use automatic number plate recognition. Here, a system of cameras

captures images of vehicles passing through tolled areas, and the image of the number plate is

extracted and used to identify the vehicle. This allows customers to use the facility without

any advance interaction with the toll agency. The disadvantage is that fully automatic

recognition has a significant error rate, leading to billing errors and the cost of transaction

processing (which requires locating and corresponding with the customer) can be significant.

Systems that incorporate a manual review stage have much lower error rates, but require a

continuing staffing expense. [5]

A few toll facilities cover a very wide area, making fixed toll gates impractical. The most

notable of these is a truck tolling system in Germany. This system instead uses Global

Positioning System location information to identify when a vehicle is located on a tolled

Autobahn. Implementation of this system turned out to be far lengthier and more costly thanexpected. [5]

6.2. Automated Vehicle Classification

Automated vehicle classification is closely related to automated vehicle identification

(AVI). Most toll facilities charge different rates for different types of vehicles, making it

necessary to distinguish the vehicles passing through the toll facility.[5]

The simplest method is to store the vehicle class in the customer record, and use the AVI

data to look up the vehicle class. This is low-cost, but limits user flexibility, in such cases as

the automobile owner who occasionally tows a trailer. [5]

More complex systems use a variety of sensors. Inductive sensors embedded in the roadsurface can determine the gaps between vehicles, to provide basic information on the

presence of a vehicle. Treadles permit counting the number of axles as a vehicle passes over

them and, with offset-treadle installations, also detect dual-tire vehicles. Light-curtain laser

profilers record the shape of the vehicle, which can help distinguish trucks and trailers. [5]

6.3Transaction ProcessingTransaction processing deals with maintaining customer accounts, posting toll

transactions and customer payments to the accounts, and handling customer inquiries. The

transaction processing component of some systems is referred to as a "customer servicecentre". In many respects, the transaction processing function resembles banking, and several

toll agencies have contracted out transaction processing to a bank. [5]

Customer accounts may be postpaid, where toll transactions are periodically billed to the

customer, or prepaid, where the customer funds a balance in the account which is then

depleted as toll transactions occur. The prepaid system is more common, as the small

amounts of most tolls makes pursuit of uncollected debts uneconomic. Most postpaid

accounts deal with this issue by requiring a security deposit, effectively rendering the account

a prepaid one. [5]

of DSRC lies within many other aspects such as road user claims, potential violations and

other aspects of electronic tolling. [6]

7.2 Vehicle Positioning System (VPS):

Vehicle Positioning System is a means for automatically determining the geographiclocation of a vehicle and transmitting the information to a requester. Vehicle Positioning

System based on combination of two technologies. Satellite (GNSS) and Mobile

Communication (GSM/GPRS). [7]

I. Global Navigation Satellite System (GNSS):A satellite navigation system with global coverage termed a global navigation satellite

system. It depends on GPS & GLONASS based on onboard unit. [8]

II. GPS- Global Positioning System, that provides location and time information in allweather and at all times and anywhere on or near the Earth.

How a GPS works?

Fig: GPS working system

Drivers goes to the payment service centre registers and installs OBU and applies for

pre-paid card or post-paid card. When vehicle moves into the charging zone, OBU compares

current vehicle position coordinate from GPS with the virtual toll node coordinate kept in the

storage of OBU. After logistic determining, the OBU sets up wireless communication

channel through GSM module. OBU sends transaction message to management centre system

by the GSM module through mobile network. After auditing the management centre saves

toll data and sends back transaction information to the OBU. The OBU receives and displays

the transaction result. If error transaction result is replied the OBU is abnormal payment state,

the OBU is still working. When the vehicle moves out the charging zone, if the OBU has

abnormal state or the vehicle doesnt install an OBU the violation will be processed. The

clearing centre clears all toll data from management centre, and divides in road serviceproviders. The Payment Service Centre collects toll records and clearing data for account

query. [9]

III. GLONASS- Global Navigation Satellite System is a radio-based satellite navigationsystem. GLONASS is a global satellite navigation system, providing real time

position and velocity determination for military and civilian users. GLONASS

satellites transmit two types of signal: a standard precision (SP) signal and an

obfuscated high precision (HP) signal. The signals use similar DSSS encoding and

binary phase-shift keying (BPSK) modulation as in GPS signals. All GLONASS

satellites transmit the same code as their SP signal, however each transmits on a

different frequency using a 15-channel frequency division multiple access (FDMA)

technique spanning either side from 1602.0 MHz, known as the L1 band. The center

frequency is 1602 MHz + n 0.5625 MHz, where n is a satellite's frequency channel

number (n=7,6,5,...0,...,6, previously n==7,...0,...,13). Signals are transmitted in

a 38 cone. [10]

IV. Global System Mobile Communications (GSM):The GSM standard has been an advantage to both consumers, who may benefit from

the ability to roam and switch carriers without replacing phones, and also to network

operators, who can choose equipment from many GSM equipment vendors. GSM is a cellular

network, which means that mobile phones connect to it by searching for cells in the

immediate vicinity. There are five different cell sizes in a GSM networkmacro, micro,

pico, femto and umbrella cells. Macro cells can be regarded as cells where the base station

antenna is installed on a mast or a building above average roof top level. Micro cells are cells

whose antenna height is under average roof top level; they are typically used in urban areas.

Pico cells are small cells whose coverage diameter is a few dozen meters they are mainly

used indoors. Femtocells are cells designed for use in residential or small business

environments and connect to the service providers network via a broadband internetconnection. Umbrella cells are used to cover shadowed regions of smaller cells and fill in

gaps in coverage between those cells.[11]

Fig: Structure of GSM Network.

The network is structured into a number of discrete sections[11]:

The Base Station. The Network and Switching Sub System. This is sometimes also just called the core

network.

The GPRS core network The Operation Support System (OSS) for maintenance of the network.

7.3 Odometer:

An odometer or odograph is an instrument that indicates distance traveled by a

vehicle, such as a bicycle or automobile. The device may be electronic, mechanical, or a

combination of the two. The word derives from the Greekwords hods ("path") or gateway

and mtron ("measure"). In countries where Imperial units or US customary units are used, itis sometimes called a mileometer or milometer. [1]

Figure: Odometer

Odometer Tolling:

There will be two service stations in the Portland area equipped with mileage reader

devices and pilot participants will be asked to fill their vehicles at these participating service

stations when convenient. When refueling, the on-board mileage counter will communicate

with the mileage readers placed at the pumps. When the purchase is totaled, the gas tax willbe deducted automatically and the road user fee will be added automatically. A federal

requirement of the Pilot Program is to test the ability to count separately the miles traveled

during rush hour within a congested area. Some of the pilot volunteers will be in a rush hour

pricing group to test this concept. Because the pilot is a test, many policy options remain for

decision-makers, such as charging a lower rate-per-mile for vehicles that achieve a certain

fuel efficiency, for motorists that avoid rush hour zones, or for those participating in other

environmentally-friendly activities. The road user fee program does not track, store or collect

private information. There is a switching device that counts the number of miles the vehicle

has travelled. The device cannot record the location of the vehicle except when the vehicle

passes through certain designated rush-hour zones. The device counts only the number of

miles travelled within the zone, not the time of day, location in the zone, or even the day. [1]

12/26



There is also a GPS receiver in the cars that simply tells the electronic odometer

whether to count the miles as in state or out of state. This is to prevent Oregonians from being

charged for miles driven outside the state. No location data is transmitted anywhere or stored

in the device or elsewhere; since vehicle location data is not collected, it cannot be accessed.

The only data collected and transmitted is the mileage, which is sent to the gas pump reader

through a radio frequency that can only travel about 8 to 10 feet. [1]

8. SCOPE OF ELECTRONIC TOLL COLLECTION IN INDIA

India has about 42.36 Lakh kilometres of road network, which is the second largest in the

world. The length of various categories of roads is as under[12]:

National Highways - 70,934 km State Highways - 1,54,522 km Major district roads - 25,77,396 km Rural roads - 14,33,577 km

And the state-wide description can be given as,

According to the report given by National Highway Authority of India (NHAI)

National Highways carry 40% of road traffic. Due to this traffic congestion is very high and

to reduce it, Electronic Toll Collection must be implemented. And its major concern is toreduce the traffic density, provides road safety and also increases the Central Governments

Economy. And National Highways Lane wise distribution can be classified as[12],

4-Lane - 22.3%

2-Lane - 52.3%

Single Lane - 25.4%

There is a possibility of maintaining ETCs on state highways as well as in busiest

hours in cities. This may leads to the reduction of congestion, pollution, traffic violation at

peak hours. [12]

By viewing all the above data, the Ministry has decided to implement a uniform

interoperable Electronic Toll Collection(ETC) System with RFID(passive chip) based

technology which offers interoperability and compatibility for seamless movement of


13/26



vehicles on tolled national highways, state highways etc. And the factors to be considered

are. [12]

The system must be interoperable nationwide, and affordable. Technologies should be tried and tested. Systems should be easy to use. ETC should be scalable to other applications. Payments should be possible through credit cards and mobile phones etc.

9. EXISTING ETC IN INDIA

In most advanced countries, ETC systems have evolved from older systems where

many of the existing technologies did not exist. Due to backward compatibility constraints,

implementing ETC models across the country has proved to be a challenge, and sometimes

complicated solutions have evolved to ensure interoperability between systems of different

toll vendors.

India has an advantage as there are no legacy systems in place, and highway

expansion has begun to take off mainly over the last decade .Consequently, there is an

opportunity to built a simple and robust ETC system that leverages modern information and

communication technologies. Presently, Electronic toll collection is used at few toll plazas on

national highways like:

I. Delhi- Gurgaon HighwayII. Bangalore-Electronic City Elevated Highway

I. DELHI-GURGAON HIGHWAY:The solution introduced on Delhi-Gurgaon Expressway is a multi- tiered processing

ability so as to accommodate the motorists and the processing speeds ensuring little to no

queuing at the Toll Plazas. The acceptance of cash and the introduction of the following cash-

less (Electronic Media to pay Toll) transaction will enable this to be achieved. [13]

Technology: Smart Tag

The Smart Tag allows a motorist to travel non-stop through the toll plaza. It is an

electronic device the size of a computer mouse which is installed in the windscreen behind the

rear view mirror of your vehicle. It is charged with the denomination of your choice and has

the capability of interacting with sensors placed at the toll gates. Which means that all youhave to do is to slow down to 20 Km/hr (you don't have to stop) near the toll gates, the sensor

at the gates interact with your Smart Tag, the transaction is recorded and the toll deducted,

you hear a confirmation beep inside your car and you're off. [13]

All of this takes less than a second and is extremely convenient to commuters and the best

way to do away with waiting periods at the toll gates. Smart tag works like a debit card, it has

no expiry and you can use it till you keep re-charging the amount in your account. Designated

lanes for Smart Tag holders have been created to ensure a seamless drive through. Any person

may apply for a smart tag device who travels on the NH-8. This could include Motorists ,

Local residents and local commercial traffic. All you need is a copy of the registrationCertificate of your vehicle and you can register for the Smart Tag at the following locations as

per your convenience: [13]


14/26



1. Point of Sale Office at the KM 24 Toll Plaza at the Delhi-Gurgaon Border

2. Point of Sale Office at the KM 42 Toll Plaza near Haldiram on NH 8

3. Point of Sale Office at IGI Airport Toll Plaza

Rules for vehicle with Smart Tag:

The smart tag based ETC implemented at Delhi-Gurgaon Highway is basic model and works

under certain constraints which are mentioned below.[13]

Tag users are required to proceed only after observing green traffic signal.

Tag users are required to maintain approx. 2 car length distance while crossing toll gate.

Speed of the vehicle should not be more than 15 km while crossing the toll gate.

Tag is not an authority to move freely without following traffic rules. Being electronic item

there can be instances when the system doesnt work.

Dont move on hearing the beep sound coming out of tag. Look out for a green Traffic light

only.

Each vehicle will be required to have its own Smart-Tag. If anyone tries to tamper the

device, a tamper switch which is monitored by the system and will result in hot-listing of the

account.

If there is any problem in the Smart-tag, the consumer should visit the POS and get the

Smart-tag checked. It will be replaced if it has not been tampered with.

Speed limits in a nonstop Smart Tag lane must be not more than 15 Km/h for the safety of

commuters.

The same Smart-tag can be used at all the three toll plazas on the Delhi - GurgaonExpressway, this Smart-tag cant be used on any other toll road across the country as DG

Expressway is the only toll road in India which offers Smart-tag technology.

In case the customer changes his/her vehicle or changes the existing fleet, change in

particulars need to be filled in, which would then be available at all the three toll plazas to

avoid any inconvenience.

If the Smart-tag is lost or stolen, the customer should report it to the Point of Sale in writing.

The customer will be held responsible for any loss from the use that Smart-tag for 48 hoursafter the loss has been reported in writing. [13]


15/26



Smart-tag antenna requires the device to be in a certain position and angle on thewindshield.

Invalid card: If the card to which the Smart-Tag is linked is no longer valid the Smart-tagwill not function as system automatically checks the validity of the linked card, before

opening the boom.

Functionality:

A centralized back office operation or Central Toll Clearing House is mandatory for

the operation of nation-wide ETC systems. The Central Clearing House concept is a

transaction management which will enable multiple toll collection agencies to share toll

transaction data and revenue reconciliation. It is convenient and easy for a road user to use a

common payment mechanism which can be accepted at all toll plazas. Irrespective of the toll

plazas being operated by NHAI or BOT concessionaries, the reader system at each toll plaza

debits the applicable amount from the smart card of users. Every Toll plaza shall have thefacility to account for ETC based payments, and all such transactions for the day are sent to

the central toll clearing house (CTCH) as claims. The CTCH runs an end of the day

settlement and sends files to every toll plaza and point of sales outlet for their receivables for

that particular day. Such files are then sent to the bank for conducting finanancial settlements

to the particular bank accounts of all the collecting agencies.[13]

II. BANGALORE ELEVATED TOLLWAY LTD:A Consortium of Soma Enterprise Ltd (Soma), Nagarjuna Construction Company Limited

(NCCL), and Maytas Infra Limited (Maytas) has built a 9 Km long 4 lane Elevated Divided

Carriageway Road between Silk Board Junction and Electronic City Junction on a Build,Operate and Transfer (BOT) Basis for the National Highways Authority of India (NHAI).

The Consortium will operate and maintain the roads in the stretch between Silk Board


16/26



Junction and Inter State Border for the next 18 years. Bangalore Elevated Tollway Ltd

(BETL), which has been awarded the expressway project on the Bangalore-Hosur section of

the National Highway connecting the Electronic City, has proposed a toll of Rs 10 to Rs 70

per trip for different modes of vehicles, including heavy commercial vehicles. [15]

Technology: Passive RFID

Toll booths on National Highways will adopt the passive RFID technology standard ISO

18000 6Cfor electronic toll collection (ETC) system, based on the recommendation of a

committee set up for this purpose, headed by Mr Nandan Nilekani, Chairman, Unique

Identification Authority of India (UIDAI). The recommendations have been adopted by the

Highways Ministry. In the ETC system, vehicles will have tags on their windscreenswhere

amounts can be pre-loaded (just like prepaid SIM cards for phones) and when the vehicles

pass through NH toll lanes with tag readers, the toll amount would automatically get debited.

This will pave the way for setting up of ETC system across the NH network.

There are about 147 toll booths on the NH network, out of which about 100-odd are operated

by NHAI and remaining by private developers. Each reader will cost about Rs 2 lakh. Each

NH toll booth will have at least two lanes (one on each side) with tag readers. NHAI or theoperating concessionaire is likely to bear the cost of setting up tag readers at its toll plazas

though the Union Highway Minister, Mr Kamal Nath, said he expects the system to be self-

financing. It is also not clear as to who will fund the clearing house operator. At present, two

NH stretches have ETC options Delhi-Gurgaon Expressway and Bangalore-Electronic City

elevated highway. [14]

10. STANDARDIZATION OF ETC IN INDIA AND ABROAD

More recently there has been a move to standardize ETC protocols around the Dedicated

Short Range Communications protocol that has been promoted for vehicle safety by theIntelligent Transportation Society of America, ERTICO and ITS Japan. Whilst

communication frequencies and standards do differ around the world there has been a trend

toward vehicle infrastructure integration (VII) around the 5.9GHz frequency (802.11.x

WAVE). [16]

The Association of Toll and Traffic Systems Integrators of India (ATTSII) has

recommended guidelines for a suitable Electronic Toll Collection (ETC) to the working

group formed by the Committee of Road Safety and Traffic Management, Ministry of

Surface Transport and Highways to determine the technology for Advance Traffic

Management Systems, Advance Travel or Information Systems and Electronic Toll collectionSystems. The association proposes CEN 278 standard based on DSRC (Dedicated Short

Range Communication) microwave technology for the Indian subcontinent keeping in mind

the Indian environment and driving conditions. [16]

CEN 278 is the most acceptable technology worldwide with interoperability

standards. It is already successfully implemented at the Delhi Gurgaon Expressway, the

largest 32 lane toll plaza in India. Introduction of smart tags based on microwave technology

has received overwhelming response from drivers who earlier had to wait in long queues for

several hours at the Toll. Now, it only takes few seconds for each vehicle to pass through,

significantly reducing waiting time. [16]


17/26



CEN 278 is a cost effective technology as multiple vendors are present in the market

to ensure that customers get the best competitive deal. IRD have successfully implemented

CEN 278 standard microwave based Electronic Toll Collection(ETC) technology in April

2006 at Hoogly River Bridge Commissioners (HRBC) site at Vidyasagar Setu Kolkata.

HRBC is a West Bengal Government organization for operation, implementation and

maintenance of Hoogly Bridge. Currently, it has 24 lanes at 1 Plaza with 4 ETC Lanes and isefficiently meeting requirements of the department to cater to heavy traffic volumes in a

matter of seconds at the entry to Kolkata city. [16]

Most of the Build Operate Transfer (BOT) operators are opting for technology for

ETC which is more cost effective and operationally efficient for Indian conditions. The major

advantage of the microwave technology is the presence of numerous vendors in the market

that generates fair competition. We must understand the emerging traffic volume in our

country and we must opt and guide for technology which best meets diverse user needs and

national interest, rather than being guided by commercial interest of vendors. CEN 278

standard is based on microwave technology, making it more reliable, robust and viable. [16]

At a time when India is starting to put in place the ETC technology, it should adoptthe most advanced technology that is pre tested, allows wider applications and faster data

transfer speed. We cannot afford to lose time in deciding on a technology as there is an urgent

need to meet the ever increasing traffic management requirements in India that suits the

masses and is most viable to implement. [16]

11.RECOMMENDATIONS FOR IMPLEMENTATION OF ETC IN NANDANNILEKANI REPORT.

The Government of India has decided to implement Electronic Toll Collection across

the National Highway Network, which would enable to collect toll when vehicle is in motion.Hence the government of India constituted a committee under Shri Nandan Nilekani,

Chairman Unique Identification Authority of India and other expert members to propose ETC

system and technologies to be implemented for Indian Environment.

11.1 Automatic Vehicle Identification:

The committee has suggested the use of RFID (Passive) Tag and Reader based on

EPC, Gen-2, and ISO 18000-6C standard for the Indian Environment. This is suggested based

on the availability of multiple manufacturers/vendors, cost being very less when compared to

other techniques and simplicity. The ETC in India is expected to require not more than

2.5Mbps date rates. In many places in USA and Europe it is observed that ETC where other

technologies were adopted have shifted to RFID based passive technology because of itsadvantages.

11.2 Toll Charging:

A central Toll Clearing House (CTCH) will maintain all the financial transactions. All

the toll plazas are to be connected to the Clearing House through WAN. Every toll plaza has

the facility to account for ETC based payments, and all such transactions for the day are sent

to CTCH as claims. The CTCH runs an end of the day settlement and sends files to every toll

plaza.. The CTCH also interacts with the bank for financial settlements to the particular bank

accounts of all the toll collecting agencies.

11.3 Automatic Vehicle Classification:With the proposed architecture and the RFID tag recommended, vehicle classification

is done based on the classification of the data in the RFID Tag which is read by the reader.


18/26



Each lane in the toll plaza can be equipped with independent AVC systems for crossing

checking the class of vehicles by the ETC reader. Vehicle classification is done by use of

code in the tag. However, to detect misuse of tags, it is recommended that a alternative means

of AVC should be available. This is left to the toll plaza operator.

11.4 Violation Enforcement System (ANPR):Violation can occur when vehicle tag does not have enough money or tag when

passing through the ETC lane. Stopping the violated vehicle will mitigate the benefits of

ETC, as vehicle blocks the traffic. Hence it is important to identify the violator without

stopping the vehicle. LPR system helps in this aspect. But the committee is of the opinion

that it is difficult to handle to violator without stopping. So violator needs to stopped and

penalised at the toll plaza by the enforcement authorities. A proper legal framework should

exist for penalizing the violators for effective Implementation of ETC.

The committee has suggested the importing of Technology so that OBU and Tags

become cheaper and are not burden to common man.

11.OBJECTIVES OF TIFAC CORE IN ETC:The committee formed by the Government of India has studied the major ETC

implemented worldwide and the Indian Scenario and proposed the best architecture with

technologies for ETC in India. The objective of the TIFAC CORE in Telematics is to

implement a Pilot Project with the above recommendations and test in real time. This is done

to identify the real time constraints in implementation of ETC in India. The CORE will also

explore various technologies and architectures for implementation of Automatic Vehicle

Identification, Automatic Vehicle Classification, Toll Charging and Violation Enforcement

Systems in Indian Scenario.

Goals:

The work plan of the pilot project will be divided in terms of short term goals and

long term goals. The short term goals are aimed at work plan for one year i.e.2011-2012

academic year and the long term work plan will be for 2 years and beyond.

12.1 Short term goals:

The short term goals w.r.t ETC pilot project will be:

1. To survey information about various toll plazas implemented with differenttechnologies across the world.

2. To study in detail various recommendations for ETC given by the Nandan NilekaniReport.

3. To identify specifications and design a base model with major three sub-blocks (AVI,AVC, and VES) of RFID based ETC system for Indian Scenario.

4. To design and implement the proposed system with real time considerations.5. To test and analyse the results of the RFID based ETC system implemented in real

time scenarios under various conditions.


19/26



12.2 Long term Goals:

The long term goals w.r.t ETC pilot project will be:

1. Based on the observations from the implementation of RFID based system,improvements or better alternatives at sub block level will be explored andimplemented.

2. ETC system can be implemented with various other technologies like GPS, GSM etc.These systems will be explored and the pilot projects in the same for Indian Scenario

can be implemented.

3. A report detailing issues in implementation of various ETC systems in IndianScenario will be generated.

14.ETC PILOT PROJECT:The ETC pilot project will involve design and implementation of a base model system. The primary

objective of the design will be to achieve the correct functionality at system level and sub-block level.

14.1 Design:

The base model of the RFID based ETC system will have three sub-blocks:-

1. Automatic Vehicle Identification (AVI)2. Automatic Vehicle Classification (AVC)3. Violation Enforcement System (VES)

(Unlike the original RFID based ETC system, a simple model of Toll Processing Unit will be

implemented. The Toll Processing Unit will be integrated in to the AVI unit for this pilot project

implementation.)

The functionality of the above three components are discussed in 6.1, 6.2, 6.3. in detail. The

algorithm for implementation of each sub-block at higher abstraction level is given as follows.

14.1.1 Steps Involved in Automatic Vehicle Identification Implementation (AVI)

1. RFID Tag and Reader Configuration, Tag in vehicle is read by the RFID reader.2. Road Side Unit for processing by comparison of vehicle class and deduction of amount

information.

3. Database for storage of records of the customers. The information in database in read bythe RSU when needed

4. Road Side Unit needs to communicate with the AVC to get the actual vehicle class forcomparison and VES system when there is violation.

15.CONSIDERATIONS FOR ETC15.1 Considerations for ETC Automatic Vehicle Identification

RFID Reader of 865 MHz to 867 MHz that cover range of 3 to 5 meters will be chosen. Thevehicles speed is restricted to maximum of 40 Km/Hr

RFID reader reads the Unique Identification Number from the RFID tag in the vehicle. Theplacement of tag for reader to identify and the speed of the vehicle is important.

RSU receives the Unique Identification Number (UIN) from reader, codes it in particularformat and retrieve the details from the database using the coded UIN. Security is a major

concern as any other device with same frequency should not be able to read UIN and access

database.

RSU sends the coded UIN to database based on which it retrieves the details like UIN,Vehicle Registration Number, Owner name, Owner Address, Type of Vehicle, and recharged


22/26



amount associated with the vehicle from the database. The details can all be retrieved at once

or the individual data can be retrieved.

RSU then performs the operation of matching the stored vehicle class information in thedatabase details from the identified vehicle class from the real time system at the toll plazas

information. If both vehicle classes do not match, VES is enabled to retrieve the License plate

number and the address of the owner. Vehicle can also be stopped for fine collection. Here

timing is a major concern as the real time AVC measured and the AVC from database should

be of the same vehicle. Hence there is a need for synchronization between two systems.

If both match then deduction of the required amount is done from the amount in the detailsretrieved from the database. If there is no sufficient amount then violation enforcement

system is enabled. The database is updated with changed amount after the above operation.

Here since financial transaction is involved the security, correct amount deduction and in time

updation of database with updated amount is a necessity.

Database should also be updated when the tag is recharged by the user. This is why databaseis designed with two modes of operation-one updation when toll charge is deducted and

second when it is recharged by customer.

Database will be developed for 100-150 customer databases covering various types ofvehicles.

Although a central database and local database needs to be created and there are differenttypes of accesses and modifications that each level can have, here we choose to develop just

one database with above details.

Its important to achieve faster access time between reader, RSU and database. 15.2 Considerations for ETC-Automatic Vehicle Classification:

Vehicle Classification System is the done using various algorithms for classifying differenttypes of vehicles in various conditions.

Algorithms developed will be verified for real time inputs from Indian scenario under variousweather and road conditions in India.

Vehicle Classification algorithms can depend on various factors. One key factor is day timevehicle classification or night time vehicle classification.

Vehicle classification is broadly classified using the following systems:o Video Imaging Systemso Fibre-optic treadles.o Laser Classifiers.o Optical Height Sensors.o Optical Axle Counters.o Infrared Light Curtains.o Magnetic Sensorso Weigh in Motion concept.o Acousticso Mix of Technologies

For the pilot project a standard classified list used in Indian Toll Plaza is chosen. All vehiclesunder each class are listed and the developed algorithm should use any of the above types and

classify correctly in to the pre-defined classes.

Generally different vehicles like trucks, Lorries etc are grouped in to one single class; hencealgorithm should also do the same.

The real time input will streamed LIVE and then analysed using the algorithm implementedon hardware and class should be displayed.


23/26



It is mandatory that the algorithm designed considers various weather considerations.Mention any constraints/Limitations your algorithm have w.r.t vehicle type or weather/Road

conditions.

The output will be generated in the format required for display and also in the compatibleformat so that it can be give as input to RSU in AVI.

The time interval between vehicles required detecting and classifying all the vehicles and alsothe maximum speed with which it should travel for AVC system to classify the vehicle will

be considered.

15.3 Considerations for ETC - Violation Enforcement Systems:

Vehicle Enforcement System will use License Plate Recognition. The algorithms developed for License Plate Recognition should consider processing of

images under various conditions like day time, night time.

Various algorithms will be explored for training the characters, numbers, symbols of variouslanguages and fonts.

Other challenges such as strategies for non-standard number plates, detection of number platelocation correctly as they might be placed at different locations for different kinds of vehicles

in India should be addressed.

The violation enforcement will also include speed detection, as the ETC system strictlyrequires the vehicle to travel with not more than 40 Km/hour.

The VES system and AVC system can be two interworking systems.

16.PROJECT EXECUTION PLAN: The pilot project will be executed by the faculty and students of ECE department in the

duration of one year.

Faculty will choose their area of interest from AVI, AVC and VES. Based on the topic chosen the faculty groups will be formed and a faculty coordinator for

each group will be nominated.

The guides of similar group along with the group coordinator will formulate a plan fordivision of work and implementation of the entire system.

The student batches interest of working in particular area of interest from the above threeareas (AVI, AVC, VES) is considered and the respective batches are allotted to the

corresponding guides.

Project specifications will be defined for individual projects after discussions between facultyand their respective batches.

The Miniprojects and Final year projects will be part of this pilot project implementation. The overall progress will be monitored on regular basis by the Project Review Committees,

HOD- ECE Department, Ms.M.Padmaja-Coordinator, B Tech Final Year projects and

Mr.M.Kantikiran, Coordinator, Mini-projects and PG projects.
