A REPORT ON THE USER'S MANUAL FOR DIAMOND INTERCHANGE SIGNALIZATION--PASSER III

The report describes the user's manual for PASSER III, a practical computer program developed to assist the traffic engineer in determining optimal traffic signal timings for pretimed or traffic-responsive, fixed-sequence signalized diamond interchanges. The program is applicable to isolated interchanges as well as to a series of interchanges through which progression is desired along the frontage roads. In addition, design engineers may use PASSER III to evaluate the effectiveness of proposed interchange design alternatives. PASSER III can evaluate any signal timing plan that might exist at a signalized diamond interchange. The program also determines the level of service for each phase at the intersections which make up a diamond interchange. PASSER III provides all data required to implement the signal timing plan it calculates. Two typical example programs, an isolated interchange and a frontage road progressive system, were coded and executed by PASSER III. The completed input data card coding forms and the program output, including time-space diagrams for the progression solution, are contained in the report.
