An Advanced Ambulance Rescue System Using Prioritized Traffic Switching

SKU: Ambulance Rescue System Using Prioritized Traffic Switching Categories: ,



Traffic congestion and tidal flow management were recognized as major problems in modern urban areas, which have caused much uncomfortable for the ambulance. Moreover road accidents in the city have been nonstop and to bar the loss of life due to the accidents is even more crucial. To implement this we introduce a scheme called AARS (Automatic ambulance rescue system). The main theme behind this scheme is to provide a smooth flow for the ambulance to reach the hospitals in time and thus minifying the expiration. The idea behind this scheme is to implement a ITS which would control mechanically the traffic lights in the path of the ambulance. The ambulance is controlled by the central unit which furnishes the most scant route to the ambulance and also controls the traffic light according to the ambulance location and thus reaching the hospital safely. The server also determines the location of the accident spot through the sensor systems in the vehicle which encountered the accident and thus the server walks through the ambulance to the spot. This scheme is fully automated, thus it finds the accident spot, controls the traffic lights, helping to reach the hospital in time.


  • There is loss of life due to the delay in the arrival of ambulance to the hospital in the golden hour. The ambulance in the traffic signals. It would be of great use to the ambulance if the traffic signals in the path of the hospital are ON.
    • Post Accident Detection Systems
    • Lack of Intelligence in the detection systems.
    • Fails to track the collision and pre-damage status
    • Way of monitoring people to be manual
    • Time delay (first aid).                                 



  • A new design for automatically controlling the traffic signals and achieving the above mentioned task so that the ambulance would be able to cross all the traffic junctions without waiting.
  • For easy access the server maintains a database for each node, and hence each node will have a unique id for addressing it.
  • The ambulance is guided to the hospital by the server through the shortest route. The vehicle unit installed in the vehicle senses the accident and sends the location of the accident to the main server. The main server finds the nearest ambulance to the accident spot and also the shortest path between the ambulance, accident spot and the nearest hospital.
    • Wireless technologies used for information transferring.
