Effective and Robust Coordination of Traffic Signals on Arterial Strees. Volume 2: Guidelines of Design; Final rept

摘要

These guidelines focus on the use of the software package Synchro/SimTraffic in designing traffic signal plans for arterial streets. This package in general effectively reduces the efforts of traffic systems engineers and improves the quality of the designed coordination. However, it is noted that sometimes advanced knowledge and techniques beyond the routine use of the software are needed to obtain satisfactory signal solutions. Two cases are frequently encountered and reported by INDOT signal systems engineers: (1) the initial solution is not fully in line with the INDOT criteria for a good coordination plan; and (2) additional field-tuning is needed since the actual operational performance of the signalized arterial system deviates substantially from the performance predicted with the software.
