The Automatic Ambulance Rescue System (AARS) aims to address traffic congestion and improve ambulance response times in urban areas by automating traffic light control along the ambulance's route. When an accident occurs, a vibration sensor detects it and sends an alert with location coordinates to a central control unit, which then notifies nearby ambulances and changes traffic lights to green. This fully automated system enhances efficiency in emergency response and aims to minimize loss of life.

1. AUTOMATIC AMBULANCE RESCUE SYSTEM
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 an IT’S 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.
Existing System:
Till now there should be the need of manual power to intimate the accident to the
ambulance. It will lead to the human losses. So we go for the GSM based system to intimate the
accident to the ambulance from that place itself.
Proposed System:
In proposed system if a vehicle has met accidents, immediately an alert msg with the
location coordinates is sent to the Control center. From the control center, an msg is sent to the
nearby ambulance. Also signal is transmitted to all the signals in between ambulance and vehicle
location to make it green. The vehicle accident observed using vibration sensor and in the control
section it is received by the microcontroller and then the nearby ambulance is received from the

2. PC and controller sends the message to the ambulance. The signal to Traffic signal section is
transmitted through RF communication.
