Automation of traffic light control (TLC) systems is the major focus area compliant with Industry 4.0. The majority of the adaptive TLC systems are designed for homogeneous traffic of four-wheeler vehicles and are responsive to the prevailing traffic conditions at a junction. Further, they do not serve priority vehicles such as public transport (buses) or emergency vehicles (ambulance, fire trucks, etc.). The traffic dynamics considered in this work are less-lane-disciplined, heterogeneous traffic (two-three-four-wheeler vehicles), as found in the majority of developing countries. This work proposes a novel adaptive TLC system for heterogeneous traffic scenarios which is responsive to the prevailing traffic conditions at a junction, and also serves priority vehicles at a preference than the regular traffic. The proposed system supports multiple levels of priority among the priority vehicles, and efficiently schedules traffic lights at a junction to cause minimal interruption to the other regular traffic.
