Road traffic management is an ongoing challenge. Machine vision (image processing), RFID gates, aerial surveillance, and/or remote sensors technologies are usually used to reduce traffic management problems. However, their major drawbacks are installation difficulties, maintenance over the time, error handling, coverage and cost effectiveness. Thus, low-cost, flexible, easily maintainable and secure traffic management support systems are in demand. Internet-based real time bidirectional communication can be an alternation to solve most of the addressed problems. It can provide significant benefits over the existing surveillance technologies in use to monitor road traffic condition. In addition, dynamic routing is a vital requirement to make the proposed system more realistic. Therefore, decision tree based logic is applied to calculate the road segment weights and provide dynamic routing. The results indicate that the proposed traffic management support system/tool with dynamic routing (weights) is much more effective to find the optimal routes.
