Road traffic accidents (RTAs) have turned out to be India’s biggest emerging challenge. Road safety is an issue of global concern on human life and property. In India more than1,37,000 people were killed in road accidents in 2013 alone, which is greater than the number of people killed in all our wars put together. The main of work is focused on the development of a novel and unique automotive sensor system for the measurement of relative position and orientation of another vehicle in close proximity. The Sensor system based on the use of Ultrasonic sensors and Infrared Sensors, which measures obstacle from some distance. The use of both ultrasonic sensor and infrared sensors in order to measure small inter vehicular distance of the automotives. While the ultrasonic sensors do not work at very small inter vehicle distance and have low refresh rates, their use during short initial time duration leads to a reliable estimator. Voice guidance is used to warn the vehicle after measuring the distances from the sensors. The results show that planar position and orientation can be accurately estimated for a range of relative motions at different oblique angles.
