Evaluation of Lane Closure Strategies for Interstate Work Zones

摘要

A systematic procedure was developed in the present study that can be used tomake a decision regarding the appropriate lane closure strategy at a particular interstate work zone. Four criteria were identified which include such a decision, namely user travel time and vehicle operating cost, traffic control cost, safety, and contractors' convenience. The influences of these criteria were aggregated using the Analytic Hierarchy Approach. The procedure developed in the present study is systematic in nature, simple to use and sensitive to the policy adopted by a transportation agency. A computer program, LANECLOSE, was developed which can be readily used to select the appropriate lane closure strategy.
