Traffic Control for Reversible Flow Two-Way Left-Turn Lanes: State-of-the-Art Report

摘要

This report contains traffic control and effectiveness information for 19 sites with reversible flow, two-way left-turn lane operations. In addition to a detailed description of the traffic control systems, the safety and operational impacts of systems are reported. Also, observations of motorist compliance and problems with each system are discussed. Installation and maintenance cost data have been indexed to 1983 costs to provide a relative comparison among the six basic types of traffic control. Recommendations are presented for laboratory studies to identify traffic control systems that are understood by motorists and meet site-specific conditions, community acceptance, and local budgets.
