THE USE OF BINARY CHOICE DECISION PROCESS FOR ADAPTIVE SIGNAL CONTROL

This paper identifies and discusses several issues concerning the use of binary-choice decision process for signal-timing adjustment. The problem of making binary choice decisions for timing adjustment is described, and several issues related to the acquisition and synthesis of traffic information for decision making are then identified and analyzed through computer simulation. It is noted that adaptive control based on the binary decision process can use a very limited amount of advance information to produce efficient signal operations. In applying this decision process, the use of incorrect average travel timing in modeling vehicle arrival patterns has only a slight impact on control efficiency, if the discrepancies between the assumed and the actual average travel times are less than 4 sec. To facilitate a binary choice, it is not necessary to evaluate a large number of alternative green extensions.
