Accident prevention smart zone sensing system

Every year about 1.3 million of people dies in road accident, besides 20–50 million are injured or disabled. Most of them occur as a result of ignoring traffic signals and signs. The conventional system for traffic signs and signal, shown through the road sided sign post or traffic signal post, may pass unnoticed due to bad weather conditions or driver's ignorance or other distractions. This study proposes a system that combines a smart traffic signaling technique and a smart automobile to avoid the road accident. The smart automobile consists of a micro-controller, sonar sensor and a RF receiver with a display embedded in a car whereas the smart traffic signaling system consists of a microcontroller based RF signaling transmitter that placed in every traffic signal or sign post. The sonar on the smart automobile will help to avoid clash by measuring the distance of surrounding vehicles. Therefore, the proposed system ensures that no vital traffic sign will go unnoticed, whatever the condition is. It can be utilized in special areas with sudden sharp & high curve, heavy traffic zones.
