LABORSAVING METHODS FOR IMPROVED OPERATION OF COMPUTER-CONTROLLED TRAFFIC SIGNAL SYSTEMS: 1.5 GENERATION SYSTEM FUNCTIONAL DESCRIPTION AND SOFTWARE DEVELOPMENT GUIDELINES

This report provides a functional description of the 1.5 Generation control system concept. The system described is the one which was found to be the most effective of several alternatives studied in the analyses of References 1 and 2. The material of this report serves as a basis for developing design specifications for the 1.5 Generation system applications software. The primary objective of the 1.5 Generation control system is to reduce the labor intensiveness of the task of developing pre-stored traffic signal timing plans used in the First Generation central computer controlled signal system. A secondary objective of the concept is to detect long term trends in the degradation of performance of the pre-stored timing plans used in a First Generation system.
