CONNECTED ROADSIDE TRAFFIC DETECTION AND CONTROL SYSTEM
20230186765 · 2023-06-15 ·

A system for prioritizing traffic having a traffic signal controller (TSC), a processor, a database, and one or more detectors configured to detect the presence of a vehicle having a vehicle identifier. The system is configured so that the processor is in communication with the TSC and at least one detector, and the detectors are configured to detect passing vehicles having a vehicle identifier. In a case the vehicle identifier has a record within the database, the processor an approximate travel time of the vehicle identifier between a location of the detector where the vehicle identifier is detected and a traffic signal connected to the TSC, and a command is set to be sent from the processor to the TSC to change the traffic signal connected to the TSC in a direction of travel of the vehicle identifier if one or more conditions are met. The command sent from the processor to the TSC has a delay of between zero seconds and the approximate travel time calculated.

Multi-agent reinforcement learning for integrated and networked adaptive traffic signal control

A system and method of multi-agent reinforcement learning for integrated and networked adaptive traffic controllers (MARLIN-ATC). Agents linked to traffic signals generate control actions for an optimal control policy based on traffic conditions at the intersection and one or more other intersections. The agent provides a control action considering the control policy for the intersection and one or more neighboring intersections. Due to the cascading effect of the system, each agent implicitly considers the whole traffic environment, which results in an overall optimized control policy.
