A collision avoidance system is an automobile safety system designed to reduce the rigorousness of a collision. Also known as precrash system, forward collision warning system, or collision mitigating system. It uses radar and sometimes laser and camera to detect an imminent crash. Once the detection is done, these systems either provide a warning to the driver when there is an imminent collision or take action autonomously without any driver input by braking or steering or both. Collision avoidance by braking is appropriate at low vehicle speeds. while collision avoidance is suitable at higher vehicle speeds.[1] Cars with collision avoidance may also be equipped with adaptive cruise control, and use the same forward-looking sensors.

Collision Avoidance systems, a subsequent step to collision mitigation, are one of the great challenges in the area of active safety for road vehicles. In India the total annual deaths due to road accidents has crossed 1.18 lakh, according to the latest report of National Crime Records Bureau (NCRB). If these deficiencies are not controlled at early stages they might cause huge economical problems affecting the road side networks. The main part of the work was to carry out a feasibility study on vehicle collision avoidance system using wireless sensor networks. The collision avoidance can be done by IR sensor. Vehicle collision avoidance system can be identified by IR transmitter and IR receiver. Through IR sensors the working of the DC Motor can be controlled, that is, speed of the vehicle can be controlled. The device that converts electrical energy into mechanical energy is called as a motor. A DC Motor is a type of motor that makes use of the DC supply to produce mechanical output. The aim of developing this project is to control the speed of DC motor[6] .Since the motor works at high voltage the motor cannot be directly connected to the microcontroller hence an interface called the motor driving IC is used in between the microcontroller and the motor. To achieve the speed control L293D motor driving IC . The reason for using DC Motor specially is: DC motors have higher controller efficiency, typical 98%

FRONT AND BACK SIDE COLLISION

Our nature of work is used to avoid the collision of vehicles in all directions. In case the cars are moving in front direction still we need to worry about all the other directions like back and other two sides also. If the car is moving in front direction and any other vehicle comes too closer from the front or back side, that is, the vehicle comes in the range of the sensors then the transmitted signal from the transmitting sensor will get reflected from the vehicle and gets received by the receiving sensor and so a message will be sent to the dc motor and the buzzer and so the dc motor will stop and so the car also and an alarm will be activated by the buzzer

LEFT AND RIGHT SIDE COLLISION

In case the car is going in front side if there is any vehicle coming from side direction then our both sides of the sensor will detect and send the message to the buzzer and the dc motor, and the dc motor will decrease its speed, that is, the car will slow down and an alarm will be activated by the buzzer to make driver aware of the situation
