Special Use Lanes and Ramps: Challenges to Effective Traffic Monitoring

Special use lanes and major freeway ramps present unique challenges to monitor. The prevalence of special use lanes emerged during the Vehicle Probe Project (VPP) validation data collection in New Jersey in the spring of 2009. Special use lanes include High Occupancy Vehicle (HOV), Local and Express Lanes, High Occupancy - Toll (HOT) lanes, and reversible flow lanes. Likewise, measuring delay on interchange ramps is becoming increasingly critical to order to maintain an accurate overly picture of traffic flow. The objective off this project is to characterize the challenges of accurately monitoring these facilities, review the VPP data as it provides tools in these areas, and provide guidance to Coalition members on best practice for traffic monitoring on such facilities.
