PASSER II‐84 Microcomputer Environment System—Practical Signal‐Timing Tool

Abstract

The development of the PASSER II‐84 microcomputer environment system is summarized. It was designed in research conducted jointly by the Texas Transportation Institute (TTI) and the Texas Department of Highways and Public Transportation (SDHPT) in cooperation with the U.S. Department of Transportation, Federal Highway Administration (FHWA). Significant enhancements were made so traffic engineers at virtually any location could analyze traffic operation problems efficiently. The study combined microcomputer technology and newest PASSER II‐84 for traffic engineering applications. This maximizes progression and reduces delay, stops, and fuel consumption in optimizing arterial operations. A PASSER II‐84 microcomputer environment system was developed for MS DOS‐ and PC DOS‐based microcomputers. Program documentation and revised input and output management programs were also implemented in this system.
