o Proprietary Item ApprovalsSee Section 120-4 of the TEM

Approved by Roadway Engineering

Patented or proprietary materials, specifications, or processes shall not be

included in a contract unless one of the following conditions applies: 1. The item is to be purchased or obtained through competitive bidding with equally

suitable items. In which case, the plans shall specify a minimum of two acceptable items

and include the phrase “or approved equal.”

2. No equally suitable alternate exists.

3. The item is essential for compatibility with existing highway facilities.

4. The item is used for research or for a distinctive type of construction on relatively

short sections of road for experimental purposes.

5. There is a determination by the District Deputy Director (DDD) that it is in the best

public interest to specify one such item to the exclusion of any other acceptable

alternate.

www.dot.state.oh.us/Divisions/Planning/LocalPrograms/Forms/Forms/AllItems.aspx


26 |


o Approved EqualsOn Federally Funded Projects

o If the plans list multiple products including an “Approved Equal”,

all the products including the approved equal must be listed on

the TAP.

o If the approved equal items are not listed on the TAP, and the

item is considered to be ITS related, a SEA is required to be

performed, submitted and approved if Federal Funding is to be

Used.

o Local Agencies always have the option to use their own funding

to utilized items not listed on ODOT’s TAP.


25

26

27 |


o Alternate BidsSee Section 120-7 of the TEM

o The Alternate Bid procedure has been established to permit an

agency to obtain a specific brand, feature, or design of ITS

device for use on a project when a Proprietary Item is not

justified.

o On Local projects that have Federal funding, the Local Agency is

responsible for the cost difference if the items cost more than

the base bid/generic pay item.


28 |


o Public Interest Findingo If materials are to be purchased separate from the construction

project and Federal funds are to be used on the project, a Public

Interest Finding letter needs to be sent to FHWA for review and

their approval.

o This is to state it’s in the best interests from a cost stand point to

purchase the materials separately to save money. State

contracts provide discounts on certain equipment which save

moneys.

o For example, network equipment is typically purchased separate

from the project, with project funds and installed by ODOT.

o Submit letter to Office of Roadway Engineering.

SYSTEMS AND COMPONENTS – CCTV

CCTV cameras provide an opportunity

for congestion and incident

management verification. They provide

views of the highway system that can

only be otherwise obtained by first hand

viewers and provide a great amount of

information.

ODOT records all its cameras on a 3 day

rolling window. Video is then

overwritten.

o Timing & Modes of Operationo Ramp meter must rest on green while inactive. ORC states that a dark

traffic signal indication is a stop condition.

o Minimum red time to be set to promote one vehicle per green – this may

vary slightly between sites depending on ramp conditions.

o Metering rates exceeding 15 vehicles per minute may reduce the overall

effectiveness of the operation as vehicles tend to roll through the signal

without stopping, reducing headway between vehicles entering mainline.

o “Traffic Responsive” mode allows meter to become active when mainline

congestion reaches predetermined threshold. Metering rate may

fluctuate based on level of congestion.

o “Time of Day” mode relies on a predefined schedule to activate meter

and set metering rate.


62 |

SYSTEMS AND COMPONENTS –

WRONG WAY DETECTION SYSTEMS

SYSTEMS AND COMPONENTS – HAR

Highway Advisory Radioo Highway Advisory Radio is basically an audio

version of a DMS. HAR broadcast locations

are marked by signs as shown. Signing for

HAR’s generally tells the motorist to tune

into the correct AM frequency for 24/7

traffic information and also has flashing

beacon lights for traffic alerts. When the

beacons are flashing, there is a traffic alert,

therefore motorists are advised to tune into

the appropriate AM station.

o NO LONGER USED – TECHNOLOGY BEING

PHASED OUT BY ODOT


70 |

COMMUNICATIONS NETWORKS

o Bandwidth is the rate of data that can be

transferred across the communications medium,

e.g. megabits per second (Mbps), gigabits per

second (Gbps)

o Latency refers to the time it takes data to move

from point to point on a network, otherwise

known as delay. Typically measured in

milliseconds between devices.

CALCULATIONS

o Voltage drop & Cable SizingVoltage drop is the amount of voltage loss over a length of wire due to the

inherent resistance of the wire, and is a function of voltage, current,

distance, and conductor size/material.

Vdrop = 2 x load(amps) x distance (ft) x cable resistance (ohm/ft)

Voltage drop is calculated between the power service and the ITS cabinet to

ensure the voltage supplied to the cabinet is sufficient to power the

equipment.

CALCULATIONS

o Power service sizingThe Power Service must be sized for the amp load of the ITS equipment and

voltage drop between the power service and the ITS cabinet.

Depending on the distance and the associated voltage drop between the

power service and the ITS equipment, a higher voltage power service may be

specified and a step down transformer will be installed near the ITS

equipment.
