Abstract
The emergency vehicle movement has always been a serious issue in traffic
control management. As if an ambulance is on the move it may face traffic congestions
on the roads, especially on the signals. To allow a free passage to the vehicle, traffic
wardens manually control the traffic and guide that vehicle toward its destination.
The proposed system can electronically guide the vehicle by controlling traffic
lights. The system consists of a Control Unit which has the capability of sending control
instructions to the traffic lights via GSM network.
When a vehicle starts its journey it extracts its current coordinates from the
connected GPS (Global Positioning System) device and provides it the CU along with the
desired destination location’s information by sending a SMS (Short Message Service).
The CU then interprets the SMS and according to the received information it sends
SMS’s to the traffic lights standing along its route. It also calculates the arrival time of
the vehicle and sends it to the respective traffic signal. The microcontroller at the traffic
signal then interprets instructions from the CU and according to those instructions
controls traffic lights, creating a free passage for the vehicle. It also displays the received
arrival time information. When the vehicle has passed that signal the CU then sends
control information to the next signal which also establishes a free passage and this
process is continued until the vehicle reaches its desired destination. By using the
proposed system the excessive burden on the traffic wardens as well as the time
consumption for evacuating passage for such emergency vehicles can be efficiently
