Implementation of An Emergency Vehicle to Traffic Lights Communication

First light signals for controlling traffic were operated manually by the police. The next types were operated on a ¿fixed-time¿ basis by purely mechanical devices. Later developments included linking up a number of local fixed-time controllers with a master controller. The latest and most popular types are the traffic lights that are operated by the passing vehicles themselves by using detectors placed in the roadway. Traffic blocking is a major fact that causes delay to emergency vehicles. To bar loss of human life due to accidents, Emergency Traffic Light (ETL) control system has been proposed. The main goal behind this system is to provide a smooth flow for emergency vehicles such as ambulances to reach their destinations in time and thus minimizing the delay caused by traffic jams.
