PREDICTED POSITION OFPREDICTED POSITION OF

VEHICLESVEHICLES If 10 Hz GPS receivers are used, then the vehicles can

exchange position information once every 100ms. Between two successive GPS readings the vehicles can

exchange their other dynamic information 10 times. After a new GPS reading is obtained, a vehicle can predict

(using speed, acceleration and direction, etc.) the next positions of the neighboring object vehicles, every 10

msec.

OUR PROPOSEDOUR PROPOSED

ARCHITECTUREARCHITECTURE In our architecture, a vehicle collects data from the

GPS receiver, electronic compass, accelerometer,speed sensor, etc., and then exchanges that set of data with other neighboring vehicles in order towarn drivers about impending collisions.

The successful operation of a CollisionWarning/Avoidance system will depend on howaccurately the distance between vehicles can bemeasured and how fast the set of data can beexchanged among the vehicles

CONCLUSIONCONCLUSION Intelligent Transport Systems aim to tackle the problems of roadsafety and congestion.Various safety systems exist that warn of hazards or that

automatically intervene to assist the driver.Safety systems need to be carefully implemented to avoid giving the

driver too much or too little to do.Congestion could be reduced by road charging, and by better

network management and information provision.Road charges could reflect the costs of congestion and pollution.

Integrating different systems could reduce costs.Development of new automotive systems.
