AN EVALUATION OF HIGH-OCCUPANCY VEHICLE LANES IN TEXAS. FINAL REPORT

This report evaluates the operation of freeway high-occupancy vehicle (HOV) lanes in Houston and Dallas through calendar year 1992. As of the end of 1992, HOV lanes were in operation on four Houston freeways: Katy Freeway (I-10); North Freeway (I-45); Northwest Freeway (US 290); and Gulf Freeway (I-45). The only HOV facility in operation in Dallas as of the end of 1992 was on the East R.L. Thornton Freeway (I-30E). Since 1988, an annual report has been prepared through this research project that summarizes the status and effectiveness of freeway HOV improvements in the State of Texas. This research report provides an analysis of data related to: 1) operation of the HOV lanes; 2) operation of the freeway mainlanes; 3) combined HOV lane and freeway data; and 4) data relating to transit usage and operations. Both a "before" and "after" trend line analysis (where applicable) and a comparison to control freeways are used as a means of assessing the impacts of the HOV facilities. As of the end of 1992, 46.5 miles of barrier-separated HOV facilities were in operation in Houston, while 5.2 miles were in operation in Dallas. Approximately 70,000 daily person trips are served on the Houston HOV lane system. Sixty percent of total person trips on the Houston HOV lanes are being served by carpools and vanpools, with the remaining 40 percent being served by buses. The East R.L. Thornton HOV lane in Dallas serves approximately 16,500 daily person trips. Sixty-four percent of these trips are being served by carpools and vanpools, with the remaining 36 percent being served by buses.
