Microcomputer Tool for Freeway Work Zone Planning and Scheduling

Abstract

Planning and scheduling freeway maintenance and construction activities requires the consideration of tradeoffs between the efficiency of performing the work and the inconvenience to motorists traveling through the work zone. An easy‐to‐use microcomputer software package called QUEWZ‐85 has been developed to assist agencies in analyzing the impact on motorists. QUEWZ‐85 estimates the queue lengths and additional road‐user costs that would result from alternative work zone configurations and schedules. The methodology of the analytical model is summarized and the mechanics of using the software package are described. Several successful applications of the model are discussed. Recommendations for additional research to enhance the accuracy of the model are presented.
