Within the Houston metropolitan area, a major commitment has been made to develop a system of physically separated transitways in the medians of the existing freeway network. These lanes are reserved for the exclusive use of high-occupancy vehicles. Phase 1 of the first completed transitway opened on the Katy Freeway (I-10W) in October 1984. Initially, only authorized buses and vanpools were designated as eligible users of the transitway. To encourage increased vehicular utilization of the facility, carpools were allowed to use the transitway on a test basis beginning in April 1985. The research study, sponsored by the Metropolitan Transit Authority of Harris County and the Texas State Department of Highways and Public Transportation, was initiated in order to conduct a comprehensive analysis of the effects of permitting carpools to use the transitway. The report documents data collected in October 1989, 4.5 years after carpool utilization of the transitway began. The report compares the 1989 data to similar data collected before carpool utilization was permitted (March 1985) and after carpool utilization was permitted (April 1986, October 1987, October 1988). These comparisons address numerous concerns and provide an indication of the effectiveness of allowing carpools onto the transitway.
