AUTOMATIC AMBULANCE RESCUE SYSTEM
[attachment=49734]
Abstract
Traffic congestion and tidal flow management were recognized as major problems in modern urban areas, which have caused much thwarting for the ambulance. Moreover road accidents in the city have been incessant 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.
INTRODUCTION
There is loss of life due to the delay in the arrival of ambulance to the hospital in the golden hour. This delay is mainly caused by the waiting of 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. Thus we propose 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. Every traffic junction will have a controller controlling the traffic flow. The traffic junctions are referred to as nodes and each node will have a GSM modem connected to the controller.
AUTOMATIC AMBULANCE RESCUE SYSTEM
Our system consists of four main units, which coordinates with each other and makes sure that ambulance reaches the hospital without any time lag. Thus our system is divided into following four units,
• The Vehicle Unit
• The Main Server
• The Ambulance Unit
• The Node Circuit.(Traffic Junction Unit).
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. The server then sends this path to the ambulance. Also using this information the server controls all the nodes in the path of ambulance and make it ON, which ensures that the ambulance reaches the hospital without delay. The architecture of this system is shown in the fig 1.
SENDING CO-ORDINATES TO THE AMBULANCE:
The server will also find the nearest hospital and calculates the shortest path connecting the ambulance’s current location, the accident spot and the nearest hospital. The shortest path will contain nodes in the path. The server takes the GPS co- ordinates of all the nodes in the shortest path from the NODES database and along with GPS co- ordinates of the accident spot and the hospital; it transmits it to the ambulance unit in a format specified below.
CONCLUSION
In this paper, a novel idea is proposed for controlling the traffic signals in favor of ambulances during the accidents. With this system the ambulance can be manoeuvred from the accident spot to the hospital without time lag. The AARS can be proved to be effectual to control not only ambulance but also authoritative vehicles. Thus AARS if implemented in countries with large population like INDIA can produce better results. The AARS is more accurate with no loss of time. But there may be a delay caused because of GSM messages since it is a queue based technique, which can be reduced by giving more priority to the messages communicated through the server.
