Automatic Speed Reduction System and Adjustment of Ground Clearance

Most of the road accidents occur due to over speeding and traffic violation. Running vehicle disregarding the red light has become a major problem now a day. Due to increasing number of vehicles on the road, monitoring traffic violation manually has become tedious and too complicated. Reckless driving causes serious causality and even death. The rate of road accident is going on increasing and has become a major area of concern. To reduce the rate of road accident we propose a system which controls the speed of vehicle automatically in any critical zone, without major inconvenience to driver. Here, we review a model based on RFID technology. One RFID reader inside the vehicle reads the RFID tag placed either at speed limit signboard or at traffic light. A controlling module in the vehicle then takes the decision and control the speed accordingly. It is not possible for the off-road vehicle to run at high speed on its standard ground clearance provided considering the city obstacles and on-road cars to run over the rough terrain Automatic Speed Reduction System and Adjustment of Ground Clearance Department of Mechanical Engineering Page 3 with its lower ground clearance. To obtain the good performance at high speed and low speed it is necessary to build one system which can vary the ground clearance. This can achieved by changing the suspension height so that the chassis height can be adjusted with respect to the speed and the quality of roads.
