Speed checkers for highwaysPresentation Transcript
Guided By -Prof. A. L. Renke Speed checker for highway Performed by - Abhay Mohite - Rahul Kshirsagar
Introduction While driving on highway motorist should not exceed maximum speed limit permitted for their vehicle. However accidents keep occurring due to speed violation since the drivers tends to ignore their speedometers. The speed checker will come for the highway traffic police as it will only provide digital display in accordance with a vehicle speed but also sound an alarm if the vehicle exceeds the permissible speed for the highway.

Speed (kmph) = Distance
Speed (kmph)= 0.001 km (Reading*0.0001)/3600
It will maintain the Safety of Human life on the road.
It can also be used on the bridge for the control of speed.
It can be used on the highway, express highway.
We can direct display speed of vehicle using 8085 microprocessor.
Here we implemented the “SPEED CHECKER FOR HIGHWAYS” from point of view of safety on the Mega Highway.
We feel that if Mega Highway is supported with such an faithful system then it will not only help to maintain the traffic rules but also reduces accidents.
As circuit is compact & user friendly one man can handle the system efficiently.
This project is valid for sequential flow of vehicles.
