摘要：	Several alternative lane merge strategies have been proposed in recent years to process vehicles through work zone lane closures more safely and efficiently. Among these is the late merge. With the late merge, drivers are instructed to use all lanes to the merge point and then take turns proceeding through the work zone. Its efficiency has been tested on only a limited basis. The purpose of this project was to determine when, if at all, deployment of the late merge was beneficial. The late merge concept was evaluated by comparing it to the traditional merge using computer simulations and field evaluations. Computer simulations included analysis of 2-to-1, 3-to-1, and 3-to-2 lane closure configurations to determine its impact on throughput and the impact of factors such as free flow speed, demand volume, and percentage of heavy vehicles.
