PASSER IV-96, Version 2.1, User/Reference Manual (1477-1)

PASSER IV is a program for timing traffic signals in networks based on progression bandwidth optimization. This manual describes how to use PASSER IV-96, Version 2.1, to obtain optimal signal timings. PASSER IV is capable of optimizing signal timings for arterials as well as multi-arterial closed-loop networks. The program explicitly handles one-way and two-way arterials in a network and thus is able to deal with conventional and three-level diamond interchanges in isolation or as subnetworks within a larger network of arterials. The program is composed of two modules: the user interface and the optimization module. The user interface is extremely easy to use and provides the following features: file management functions, data entry/edit modes, graphic display of network, running the optimization routine, and running the TRANSYT-7F program. Further, it provides full mouse support. The optimization module performs bandwidth maximization. In addition to its own output report, the optimization routine is capable of generating input data files for use with the TRANSYT-7F program to perform bandwidth-constrained delay minimization. Thus, PASSER IV provides a network signal-timing optimization capability that was previously available only for arterial problems through the combined use of the two programs PASSER 11 and AAP.
