Learning an Interpretable Traffic Signal Control Policy

Understand

Signalized intersections are managed by controllers that assign right of way (green, yellow, and red lights) to non-conflicting directions.

• Optimizing the actuation policy of such controllers is expected to alleviate traffic congestion and its adverse impact.
• Given such a safety-critical domain, the affiliated actuation policy is required to be interpretable in a way that can be understood and regulated by a human.
• This paper presents and analyzes several on-line optimization techniques for tuning interpretable control functions.
