The problem of traffic congestion is a significant phenomenon that has
had a substantial impact on the transportation system within the country. This
phenomenon has given rise to numerous intricacies, particularly in instances
where emergency situations occur at traffic light intersections that are
consistently congested with a high volume of vehicles. This implementation of a
traffic light controller system is designed with the intention of addressing
this problem. The purpose of the system was to facilitate the operation of a
3-way traffic control light and provide priority to emergency vehicles using aRadio
Frequency Identification (RFID) sensor and Reduced Instruction Set Computing
(RISC) Architecture Based Microcontroller. This research work involved
designing a system to mitigate the occurrence of accidents commonly observed at
traffic light intersections, where vehicles often need to maneuver in order to
make way for emergency vehicles following a designated route. The research
effectively achieved the analysis, simulation and implementation of wireless
communication devices for traffic light control. The implemented prototype
utilizes RFID transmission, operates in conjunction with the sequential mode of traffic lights to
alter the traffic light sequence accordingly and reverts the traffic lights
back to their normal sequence after the emergency vehicle has passed the
traffic lights.
