Effectiveness of California’s High Occupancy Vehicle (HOV) System

California’s HOV system comprises 1,171 lane-miles, with 803 miles in the South and 366 in the North. This study analyzes peak period traffic data from hundreds of loop detectors over many months in order to evaluate the system’s effectiveness. The study finds: (1) HOV lanes are underutilized: 81% of HOV detectors measure flows below 1,400 vehicles per hour (vph); (2) Many HOV lanes suffer degr...

Impacts of Increasing Vehicle - Occupancy Requirements on HOV / HOT Lanes

at http://trid.trb.org/view/2009/C/881189 From the abstract: This paper describes an empirical research investigation of SOV behavior in the I-394 HOT facility in Minneapolis, Minnesota, known as MnPASS. Using traffic and tolling data from March 2008, the research team conducted a visual time series analysis, price elasticity analysis, and developed a utility-based mode choice model for SOV beh...

Evaluating Air Quality Benefits of Freeway High Occupancy Vehicle (HOV) Lanes in Southern California

In the past decade, a variety of questions have been raised concerning the effectiveness of high occupancy vehicle (HOV) lanes. In Southern California, HOV lanes evaluation studies have recently been conducted, justifying the effectiveness of HOV lanes in several ways. However, very little research has been performed in evaluating the air quality benefits of HOV lanes. In this paper, a study is...

Impact of High Occupancy Vehicle (HOV) Lane Incentives for Hybrids in Virginia

This paper examines the impact of Virginia’s policy of exempting hybrid-electric vehicles from minimum occupancy requirements on state HOV lanes. Virginia registration statistics are used to compile hybrid market shares on a county level to compare the impact of HOV lane access to other socioeconomic variables. The HOV incentive is shown to have a significant impact in Northern Virginia, but no...
