Control Strategies and Detector Placement Guidelines for a 1.5 Generation Traffic Control System

摘要

The objectives of this study were twofold. The first objective was to evaluate and analyze alternative traffic signal timing optimization strategies for purposes of selecting the best strategy for inclusion in a 1.5 Generation traffic control system. The second objective of this study was to establish guidelines to be used by practicing traffic engineers in determining locations of detectors required to effectively accomplish the following functions using the selected strategy: a) computation of optimal signal timing plans in a 1.5 Generation mode of system operation; b) automatic selection of prestored timing plans in a First Generation traffic responsive mode of system operation; c) identification of 'poor' timing plan performance.
