Traffic congestion problem is a phenomena which contributed huge impact to the
transportation system in country. This causes many problems especially when there are
emergency cases at traffic light intersections which are always busy with many vehicles. A
traffic light controller system is designed in order to solve these problems. The system is
proposed to operate, when it receives signal from emergency vehicles based on radio
frequency (RF) transmission.
The proposed system includes a mechanism with an automatic traffic light
controlling system to overcome this delay of first aid service. An ambulance can thereby
easily find a freeway to reach the victim in a minimal time and thereby providing first aid
as soon as possible. This is possible by using an RF transmitter on the ambulance which
will communicate with the RF receiver mounted on the signal post in the traffic control
system. To control the traffic signals automatically, and to move towards the location in
minimal time. Thus, the traffic light gets controlled by the intelligent ambulance itself, in
such a way that it could provide free path to the ambulance.
