Automatic Reduction of Vehicular Speed in Speed Restricted Areas using Wireless Technology

Abstract

With the advanced technology being incorporated in automobiles, the acceleration in all the vehicles has been improved significantly. People using such vehicles have ver  little control on the upper speed limit of the vehicle while passing through small lanes, residential colonies as well as in speed restricted areas like school zones, banks, hospitals under construction areas etc. As a result the residents in such lanes had to resort to putting a number of speed breakers to avoid accidents. Erecting such speed breakers has many short term and long term effects both for the driver as well as the vehicle. Also, on main roads and highways, generally sign boards are kept which alerts the driver regarding speed limits at school zone, narrow road ahead, under construction area and so on so that the speed of the vehicle has to be reduced. But the driver of the vehicle either ignores the sign boards or the sign boards will not be visible due to the trees grown beside the road thereby covering the sign boards. Thus, there is a need to reduce the upper speed limit of vehicles. Also if this speed reduction is made possible without the intervention of the driver, the robustness of the action will be improved.
Thus, this paper proposes the design of a wireless communication and control system that would control the upper speed limit of vehicles traveling on a certain road. The proposed system is simulated using Proteus 7 software and implemented using PIC Microcontroller (PIC16F877A), RF Module and other related components.
