HOV Lane Performance Monitoring System

This project evaluated performance measures for HOV facilities. The northbound and southbound HOV lanes on I-270 were used for a case study based on 2013 data. Data from sources including Bluetooth and stationary detectors were imported and analyzed. An innovative data clustering method was developed to separate travel time data on HOV and general purpose lanes. Two separate algorithms based on both hard and soft clustering were examined. A fuel efficiency procedure was applied for estimating fuel savings on HOV lanes. Value of time, cost of fuel and vehicle occupancy data were collected from creditable sources. By blending travel time, volume and occupancy data several performance measures including travel time savings, person throughput, and fuel savings were calculated for HOV lanes. Economic performance of the HOV lanes was estimated by applying financial factors including value of time and fuel cost. This approach was the first attempt to evaluate performance of HOV facilities by taking advantage of traffic data from various sources. In future all components of the system will be developed and added to the integrated software. By installing Bluetooth sensors on US-50 in Maryland, the system can be expanded to cover more HOV corridors. The approach can also be used to produce performance measures on high occupancy toll (HOT) lanes.
