Design and Implementation of an Intelligent Traffic Management System with Manual Override for Emergencies.

Abstract

Nowadays traffic signal controllers are mostly based on microprocessor and microcontroller. These TSC have some drawbacks because it uses the hardware which works according to programme that does not have flexibility. In present traffic control system, fixed time interval is provided for the signals independent of traffic density. Due to this waiting time for vehicles is more so it is not efficient as vehicles consumes more fuel and at the same time causes air pollution. We exploit the emergence of new technique called as "Intelligent traffic light controller". This makes the use of Sensor Networks along with Embedded Technology. The timings of traffic signals at each crossing of road will be intelligently decided based on the traffic density on all adjacent roads. Also we have provided manual control to signals to use it at the time of emergency and failure of automatic control. So overall design of the system helps to reduce traffic congestion on road which yields to have efficient control of traffic. As we have provided manual control, we can control traffic as per necessity. So due to these advantages we go for automatic traffic control system.
