Implementation and Comparison of the Improved Traffic Congestion Control Scenario

Wireless Sensor Networks can help to mitigate the problem of congestion in cities. Congestion occurs, when the road infrastructure cannot cope with the increased demand for the particular road segment. This paper presents a congestion control system, which uses sensors installed on the road side units to monitor the data and the cars also having the capacity to collect data from the road infrastructure, will report the data to wireless traffic lights. Each wireless traffic light has its own server capable of processing data and broadcasting the information about the alternative route selection and degree of congestion among servers in another traffic zones. Cars equipped with the navigators have the capability to receive feedback from the wireless traffic lights and other cars in other traffic zones in a city and dynamically adjust their routing paths to control congestion.
