Abstract

This article describes a method of analysis to aid in determining where left-turn phasing is justified. The method, developed by the Michigan Department of Transportation, utilizes the Network Simulation Model (NETSIM) to determine fuel consumption, delay, and emissions at intersections with and without left-turn phasing. Estimated accident reduction with left-turn phasing (from a study by the Kentucky Department of Transportation) is then compared with increased fuel consumption to determine the benefit/cost of proposed multiphase signal operation.
