A Review of the Optimized Policies for Adaptive Control Strategy (OPAC)
This report gives an overview of Optimized Policies for Adaptive Control (OPAC), a real-time demand-responsive traffic signal timing optimization algorithm for individual intersections. The main difference between OPAC and traditional cycle-split signal control strategies is that OPAC does not use the concept of cycle. Rather, in OPAC, the signal control problem consists of a sequence of switching decisions made at fixed time intervals. It involves a dynamic optimization process which ensures that signal control is always up- to-date. The report discusses OPAC design philosophy, development history, implementation, and reported performance.
