In this situation especially, congestion control in wide network of intersections becomes necessary. Existing studies on traffic control algorithm mainly focused on determining the green light length in a fixed sequence of traffic. Therefore, an ef- fective traffic management algorithm would help in resolving this issue. We have developed STSC: Sensor-based Traf- fic Signal Control, an improved version of adaptive Traffic Control Algorithm, which uses a decentralized system for its opera- tion. In this algorithm we have considered four traffic phases at an intersection, which considers all the possible routes. For this we have used DSRC: Dedicated Short- Range Communications between the vehi- cles and traffic controller to adjust the phases. An additional feature of this algo- rithm is to give free pathway to emergency vehicles. We have also developed an algo- rithm for navigation purpose CTBR:Current Traffic-Based Route telling algorithm, for demand-driven route telling based on current traffic situation. It works by taking input from decentralized traffic controller at a centralized server. The per- formance evaluation shows that our work can improve in current situation and effec- tively manage traffic in a wide range of traffic intersection. This report concludes with some future work and useful remarks. KEYWORDS 1. CTBR: Current Traffic Based Rout- ing. 2. DSRC: Digital Short Range Commu- nication 3. GPS: Global Positioning System. 4.
