Presentation Description

High Occupancy Vehicle (HOV) lanes, by definition, allow access to only vehicles with a required occupancy to live up to their performance requirements. When non-HOV access is also granted, performance monitoring and correction of facilities with degraded performance become a legal requirement per Title 23 of the United States Code, section 166 (23 U.S.C. § 166). In this paper, the HOV lane performance monitoring and improvement program in California is presented, including an annual Degradation Reporting (DR) and an annual degradation mitigation Action Plan (AP). The specificities of the monitoring and reporting, causational analysis and research, treatment strategies, and project delivery challenges are discussed at length. It was revealed that up to 34% of the monitored HOV and High Occupancy Toll (HOT) facilities in California was deemed degraded due to various causes including demand exceeding capacity, speed sympathy between HOV and congested neighboring General Purpose (GP) lanes, and access issues. Efforts are ramping up across the state to mitigate the degraded performances.
