Abstract

Variable Speed Limit (VSL) is a vital component of Active Traffic Management (ATM). The VSL system manages freeways by changing the speed limits according to traffic statuses, weather conditions, and environmental indexes. It has been employed on freeways in the US and European countries. This paper provides a review of the US and European practices of VSL systems. These VSL systems have been summarized from the aspects of system objectives, VSL control algorithms, VSL evaluation methods, and evaluation results. Summary tables are presented to summarize these issues and provide additional information about the systems' regulation, data collection equipments, and display devices. Finally, based on the implemented systems, suggestions for future implementations of VSL system have been made.
