Impact of Lane Closures on Roadway Capacity, Phase 2, Summary.

摘要

In a previous project (BD545-61), University of Florida researchers developed a simulation program, FlagSim, based on major factors that influence work zone performance measures for lane closures on two-way, two-lane roads. They also developed methods to estimate traffic diversion from the work zone. In this project, the same team advanced their work by calibrating FlagSim with field data, also addressing the effect of grade on work zone performance and updating the estimation of traffic demand in work zones.
