When it comes to urban traffic and different complex situations on the road, it is observed that these situations occur due to huge increase in the number of vehicles, fixed time signals and unruly vehicle drivers. Besides it there is a requirement of making special arrangements for priority vehicles and parked vehicles on the road without disturbing the usual traffic. There are some initiatives taken up currently by the traffic authorities, but still the different systems developed for handling different complex traffic situations do not work in unison. In this paper the design and development of a Priority Vehicle Management System (PVMS) is proposed to handle lifesaving emergency services or urgency-based services. PVMS is an automatic intelligent real time system which detects the presence of an emergency vehicle at the traffic signal and provides immediate access to the priority vehicle such as an ambulance, fire brigade, the police van, and the VIP (very important person) vehicle. The proposed solution is based on multistage decision-making approach where events occurring at different stages are unknown, but probabilities of occurrence of events are known. For practical implementation a shortrange RFID (Radio frequency Identification System) system is used. Priority algorithm and mission critical option table are used for decision making if more than one priority vehicle is detected. The proposed work is complete in all the respects for all the traffic situations
