Abstract:Intelligent Transportation System in case of cities is controlling traffic congestion and regulating the traffic flow. This paper presents three modules that will help in managing city traffic issues and ultimately gives advanced development in transportation system. First module, Congestion Detection and Management will provide user real time information about congestion on the road towards his destination, Second module, Intelligent Public Transport System will provide user real time public transport information,i.e, local buses, and the third module, Signal Synchronization will help in controlling congestion at signals, with real time adjustments of signal timers according to the congestion. All the information that user is getting about the traffic or public transportation will be provided on users day to day device that is mobile through Android application or SMS. Moreover, communication can also be done via Website for Clients having internet access. And all these modules will be fully automated without any human intervention at server side.
