Variable Speed Limits: Safety and Operational Impacts of a Candidate Control Strategy for Freeway Applications
In this paper, the authors provide an analysis of variable speed limit signalization (VSLS) systems in their capacity of allowing transportation managers to provide dynamic response to presented speed limits given contingencies like weather and traffic. Two major qualifications are given regarding earlier work in VSLS which this paper attempts to investigate. First is that only a limited number of jurisdictions have applied VSLS to their roadways and thus there is little documentation to support robustness of safety and operations and, second, is that all of these jurisdictions have been in Europe and may not directly translate into North American situations or elsewhere. To correct these issues, researchers have evaluated a candidate VSLS system in Toronto, Ontario in Canada on an urban freeway. A microscopic simulation model was applied to the test site and combined with categorical crash potentiality models to estimate safety.
