Externally Adaptive Speed Controlling

As the volume of traffic on highways and roadways continues to grow at a greater rate than our roads can accommodate the effect of traffic congestion will become an ever increasing burden on city infrastructure. One solution is an adaptive system using real-time signal control to optimize signal timings and minimize delays. A large number and variety of ATCS(Adaptive Traffic Control Systems) have been developed and researched using different control methods and structure to reduce travel times and congestion. Sydney Coordinated Adaptive Traffic System (SCATS), is one such system in which it gathers data on traffic flows in real-time at each intersection. Data is fed via the traffic controller to a central computer. The computer makes incremental adjustments to traffic signal timings based on minute by minute changes in traffic flow at each intersection. It helps to allocate maximum green time for vehicles thus reducing delay. It is implemented using ATMEGA 328 controller which is cheap in cost In order to improve efficiency, an automatic speed controlling of vehicles was also done prior to this, which helps to a to avoid traffic congestion, accidents and fuel usage of vehicles.
