This paper presents a computer program which provides a tool for making choices between coordinated and free operation on an arterial roadway under semi-actuated control. The decision is made based upon a disutility function which is a combination of the number of stops on the artery and the average cross street waiting time. The program can be used on real-time signal control systems, such as closed loop systems, to dynamically identify the need to interconnect or release coordination on arterial roadway when major street traffic volume is low, such as during late night hours.
