Project Status Report
GROUP D29.4.2015
Project Overview
• Highway Safety. ITS and
Emergency Vehicle
Management System
• We are focusing feasibility,
cost analysis and some other
modifications that might have
come about in discussions.
Current Status
• What progress has been made since the previous
milestone?
• Ideas regarding Accident Trigger System, ATMS, Road
magnetization and Breathalyzers were discussed and
technical specs were discussed.
Accident Reporting System:
Stakeholder Model
GovernmentPoliceManufacturersNGOsDriversNon Drivers
The Feasibility as far as logistics go
• Accident Reporting Systems are only in its incipient stages in
India. A notable development, however, is Janwani. It has done
Vehicle Tracking Analysis and Accident Reporting Surveys in
the city of Pune.
• The Indian Govt. must plan and execute a Fatality Analysis
Reporting System or FARS to estimate the number of
accidents that happen at specific places , at specific times and
involving specific types of vehicles
BUT WHAT IS FARS?
• Fatality Analysis Reporting System (FARS) was created
in the United States by the National Highway Traffic
Safety Administration (NHTSA) to provide an overall
measure of highway safety, to help suggest solutions,
and to help provide an objective basis to evaluate the
effectiveness of motor vehicle safety standards and
highway safety programs. FARS contains data on a
census of fatal traffic crashes within the 50 States,
the District of Columbia, and Puerto Rico.
OTHER STAKEHOLDERS:
• The Police: Should help in registering FIRs of accident cases as
quickly as possible. This will also help in creating databases of
accident survey for the FARS established by the government.
• Manufacturers: Of course, the cars they provide should have
the necessary equipment compatible with the ARS technology.
• Drivers and non- drivers: With ARS in play, a lot of lives can
and will be saved.
• Hospitals: Ambulances and support services must be at the
ready and thus , coordination is essential
• NGOs: They can partake in creating awareness.
The Cost Mechanics :
• One side of the equation: Medical costs, material costs,
police costs, administrative costs of insurances , loss of
bread winners for families and pedestrians.
• The other side: Initial setting up costs, coordination ,
equipment costs, monitoring units , etc.
• Only one argument!!! Which is more costly? Life or all
these preventive measures.
A LOOK AT THE COST DATA FOR ROAD SECURITY IN SWITZERLAND
Technical aspects:
How exactly will the accident be detected?GPS and vibration sensors are used. In this system, the
vibration sensor, GPS and GSM is placed in the vehicle. If an
accident occurred the vibration sensor senses the vibration
level and if it exceeds the threshold limit, the system will
consider that
there is an occurrence of accident in that particular location.
Then the system will activate the GPS to gather the location
detail and sends the location of the vehicle through GSM to
the control station. The control stations can then notify the
appropriate agencies.
One important question?
• How will you ensure that the signal will be sent?
• Will take the help of black box technology to ensure the
controller is not destroyed in the impact of the crash.
Life saving is a team effort..
• Drivers need to follow saftey rules
• Never mix drinking with driving
• Preferable to ply below the speed limits in high traffic
zones
• Keep away from cell phones on the road.
• Be alert and active
MAGNETISATION OF ROADS
• MAGNETISATION OF ROADS AT FLYOVERS
• MAGNETISATION OF ROADS AT TRAFFIC JUNCTIONS
MAGNETISATION OF ROADS AT FLYOVERS
• At vertical curves, centrifugal force acts opposite to the
direction of Gravitational force. This reduces normal
reaction and so is the friction reduced.
• This causes difficulty in applying brakes and changing the
direction of motion of the vehicle.
• Installing magnets at top of a flyover will diminish the
effect of centrifugal force.
• N= mg- mv^2/r
• After magnetization ,
• N= mg-mv^2/r + F(magnetic)
• This will increase the friction and help the driver not to
lose control over the car.
Cost estimation
• For vertical curve of 150m radius, we need to install
magnets in area 8 x 3.5. Installing this much magnets will
cost us approx. 200 us dollars.
• The cost will increase with the decrease in radius and
increase in average speed of vehicle at the flyover.
Advantages
• Active functioning of brakes and steering.
• Reduces the chance of accidents
Disadvantages
• Electromagnets will make the flyover prone to thunder and
lightning
• Effect on the reinforcements like steel
• Will affect the magnetic systems of radios , etc.
Magnetisation at traffic junctions
• As discussed earlier , brake failures at traffic junctions
could be disastrous, so our plan is to install smart
electromagnetic technology at these junctions that will
detect brake failure and will apply external brakes.
• Smart cameras installed at these junction points will
analyse speed of a vehicle and if in given range , if its not
decelerating it will trigger electromagnetic system
installed in the road that will pull the car downward. This
will increase the normal reaction and hence , increase the
frictional force. This will lower the speed of the car.
• U= ∫m(x)B(x) dv
• F=-dU/dx (pull force)
• Force of friction would be (μ) .mg + F (magnetic)
Cost estimation
• Smart traffic cameras will cost around 28000/- and we
need 4 such cameras at each junction. High strength
electromagnets will cost us about 1000 us dollars.
• Cost for installing processors and required softwares at
the traffic junctions.
