Operational Evaluation of Dynamic Lane Merging In Work Zones with Variable Speed Limits

摘要: Intelligent Transportation System (ITS) technology has been developed to improve the safety and mobility of traffic in around work zones. In several states US, use Dynamic Lane Merge (DLM) system initiated enhance smooth operations zone areas. The DLM usually takes two forms; dynamic early merge late merge. variable speed limit (VSL) systems at zones is also one those measures. It anticipated that VSL by helping driver determining maximum he or she should travel. Besides adding improvement safety, they are expected main goal this paper report on an evaluation operational effectiveness DLMS i.e. Early Late Merge, presence a system. More specifically, VISSIM model was utilized simulate 2-to-1 configurations for six scenarios namely: Work Zone without DLMS, with DLMS. Assessment these terms throughput various demands motorists’ adherence level were conducted. found through simulation above mentioned low medium demand volume levels (V0500, V1000 V1500), there no significant difference between Maintenance Traffic (MOT) plans mean throughputs. However, higher (V2000 V2500), SDLMS produced throughputs all compliance rates truck percentages except when 2,500 vph 60%, where it produces significantly lower
