Evaluation of high-occupancy vehicle lanes in Texas, 1994. Interim research report, September 1994-August 1995

This report evaluates the operation of freeway high-occupancy vehicle (HOV) lanes in Texas through calendar year 1994. As of the end of 1994, HOV lanes were in operation on the five following Houston freeways: (1) Katy Freeway (I-10W); (2) North Freeway (I-45N); (3) Northwest Freeway (U.S. 290); (4) Gulf Freeway (I-45S); and (5) Southwest Freeway (U.S. 59S). The only HOV facility in operation in Dallas as of the end of 1994 was on the East R.L. Thornton Freeway (I-30E). This research report provides an analysis of data related to the (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` trendline analysis (where applicable) and a comparison to control freeways are used as a means of assessing the impacts of the HOV facilities.
