Arterial signal synchronization is one of the most cost effective methods for reducign vehicle operating costs and improving traffic flow performance along urban arterials. Arterial signal optimization codes, such as PASSER-II and TRANSYT-7F, have been developed to assist traffic engineers in coordinating traffic signal settings along urban arterials and around networks. The main objective of these programs can be either to (1) maximize progression bandwidth; (20 minimize disutility function; or (3) combination of the above two approaches. This paper concentrates on a comparison study between all these options of optimizing signal timings.
