Wireless Rash Driving Detection

The aim of this project is to develop a device to detect rash driving on highways and to alert the traffic authorities wirelessly the speed details and any speed violation. Accidents due to rash driving on highways are on the rise and people are losing their lives because of others mistakes. In the present system, to detect rash driving the police has to use a handheld radar gun and then aim at the vehicle to record its speed.

If the speed of the vehicle exceeds the speed limit, nearest police station is informed to stop the speeding vehicle. This is an ineffective process as after detecting one has to inform the same and a lot of time is wasted. The proposed system will check on rash driving by calculating the speed of a vehicle using the time taken to travel between the two set points at a fixed distance and then transmit the data over 2.4GHz to the central control room. A set point consists of a pair of sensors comprising of an IR transmitter and an IR receiver, each of which are installed on either sides of the road.

The speed limit set by the device is kept at the very location depending upon the traffic. The time taken by the vehicle to travel from one set point to the other is calculated by a microcontroller program. Based on that time it then calculates the speed and displays that on an LCD and also transmits the same. Moreover if the vehicle crosses the speed limit, a buzzer sounds alerting the police both at the location and wirelessly at the control room. This concept can be extended in future by integrating a camera with the system which could capture the image of the number plate of the vehicle to send that to the traffic authorities.
