Traffic jams at road crossings is a major issue in a populous country like India. During emergency situations this becomes a major obstacle, which needs to be resolved in order to save a lot of lives especially in case of medical emergencies. After analysis of these research papers, along with some corrections and new ideas, solutions and models were proposed. Out of which, one solution which was thought to be best suited, that included RFID tag and reader, was selected. Components along with specifications were listed and costing estimated. Based on infrastructure and location of traffic junction this solution was further classified into 3 types: Overbridge sensor, sideways sensor and on road sensor. These were again studied and limitations were noted of each type. RFID being placed on each vehicle (special tags for emergency vehicles like Ambulance) are detected by RFID reader. Back-end algorithms were studied and listed which will manage traffic light duration after acquiring live vehicle-congestion data from microcontroller interfaced with RFID reader. This model aims for a revolutionary change in tackling medical emergencies if this model is implemented perfectly. Although some of the limitations viz. additional infrastructure, installing RFID tags on each vehicle, additional maintenance cost needs to be resolved for this to be implemented in crowded cities of India.
