Embedded Based Accident Alert project is developed for the users to have accident alert in modern traffic system.
This device can be used in highly accidental area to avoid accidents. It consists of two transmitters and two receivers. One transmitter is connected first and a receiver is fixed just opposite to the transmitter. The other transmitter is connected at the same side but something away from the first transmitter. The second receiver is connected just opposite the second transmitter.
When the vehicle passes the first transmitting and receiving unit, it senses that one vehicle is crossing. When it crosses the second unit, it also senses. The microcontroller unit calculates the speed=displacement/time taken.
If the speed exceeds the particular value, it sends signal to the other side vehicle to be alert. The telephone controlling unit controls the telephone operation to make a call to the administrator.
The same setup is used in the other side of the bend(Road) also. A camera is connected at the critical places. It automatically captures the vehicles which cross the area with very high speed. The captured image is stored in a PC.
This project is very much used in traffic controller. It is very accurate and cost effective
