Effectiveness of California’s High Occupancy Vehicle (HOV) System
The effectiveness of California’s high vehicle occupancy (HOV) system was evaluated using traffic sensor data. Reliable peak hour speed and flow measurement data was collected from loop detectors from 700+ stations for 128 weekdays. It was found that: an HOV lane suffers a 20% capacity loss compared with multi-lane freeways; HOV lanes are either under-utilized or suffer degraded operations; HOV lanes do not measurably increase car-pooling; HOV lanes do not reduce overall congestion in a reasonably well-managed system. Much more is to be gained by operating the existing freeway system more efficiently than by adding HOV lanes. HOV facilities can, however, play an important role in a well-managed overall freeway system in California.
