This project is developed for the users to have accident alert in modern traffic system. This device can be used in highly accidental area and pin drop curves to avoid accidents.

It consists of one transmitters and one receivers. One transmitter is connected first (One arm of the curve) and a receiver is fixed just opposite to the transmitter. .

When the vehicle passes the transmitting and receiving unit(One arm ), it senses that one vehicle is crossing. The driver circuit senses vehicle crossing.

If the vehicle particular place, it sends signal to the transistor driver for vehicle to be alert. . Also it captures the vehicle and transferred to the pc.

This project is very much used in traffic controller. It is very accurate and cost effective

Power supply

The power supply unit consists of a 0-12 1A step down transformer. The output of the transformer is given to a full wave rectifier. The rectifier circuit rectifies the AC voltage into DC voltage. The output of the rectifier is given to a 5V regulator. The regulator regulates the DC voltage to 5V which is necessary for the microcontroller and other electronic components


Two pairs of IR Transmitter and Receiver are used as sensors. The transmitter is an IR LED and the receiver is IR receiver TSOP1738. When Infra red rays falls on the sensor, it conducts electricity according to the amount of IR rays falls on it. Two sensors are connected just opposite to the two IR Transmitters
