Title: A Comparative Safety Study of Limited versus Continuous Access High Occupancy Vehicle (HOV) Facilities
Abstract: This report presents a summary of findings from comparative studies of the safety performance between two different types of High Occupancy Vehicle (HOV) facilities in California: continuous access versus limited access. The findings indicate that HOV facilities with limited access offer no safety advantages over those with continuous access. This determination was reached, based on measurements by percentage of collisions, collisions per mile, collisions per vehicle miles traveled (VMT), or collision severity. The author also investigated the relationship between HOV design features and safety performance of HOV facilities, taking into particular consideration a key design feature of shoulder/total width. The findings reveal that maintaining adequate shoulder and total width is essential. A quantitative estimate for the relationship between shoulder and total width versus safety performance of HOV lanes is provided. The report also documents the findings from investigations of other influential factors on safety performance of HOV facilities, such as design features of the ingress/egress section in limited access HOV facilities, congestion, and High Collision Concentration Locations.
