This document describes a speed checker device for highways that uses lasers and light dependent resistors (LDRs) to detect the speed of passing vehicles and display their speed digitally. If a vehicle exceeds the maximum permitted speed, the device will sound an alarm. It provides the block diagram, components used, operating principles, and potential applications and future developments of the speed checker to enhance safety on highways.
Speed checkers for highways
- 1. Guided By -Prof. A. L. Renke Speed checker for highway Performed by - Abhay Mohite - Rahul Kshirsagar
- 2. 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.

- 6. IC 555 Modes of operation MONOSTABLE. ASTABLE.
- 7. Circuit diagram IC 4026 IC 555 Power Supply
- 8. Formula Speed (kmph) = Distance Time Speed (kmph)= 0.001 km (Reading*0.0001)/3600
- 9. Application 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.
- 10. Future development We can direct display speed of vehicle using 8085 microprocessor.
- 11. Conclusion 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.
- 12. Limitations This project is valid for sequential flow of vehicles. It is only for one-ways.
