AN ASSESSMENT OF CARPOOL UTILIZATION OF THE KATY HIGH-OCCUPANCY VEHICLE LANE AND THE CHARACTERISTICS OF HOUSTON'S HOV LANE USERS AND NONUSERS. FINAL REPORT

In an effort to address the congestion problem and improve mobility levels within the Houston metropolitan area, the Metropolitan Transit Authority of Harris County and the Texas Department of Transportation have joined together to develop an extensive system of high-occupancy vehicle lanes within the medians of the existing freeway network. Phase I of the first completed HOV lane opened on the Katy Freeway (I-10W) in October 1984. Initially, only authorized buses and vanpools were designated as eligible users of the HOV lane. To encourage increased vehicular utilization of the facility, carpools were allowed to use the HOV lane on a test basis beginning in April 1985. Texas Transportation Institute (TTI) is currently monitoring the impacts associated with permitting carpools to use the HOV lane. In addition, TTI is also engaged in an assessment of public attitudes concerning the HOV lanes being developed in Houston. This assessment is being accomplished through the periodic distribution of survey questionnaires to both HOV lane users and nonusers. This report documents data collected in the Katy Freeway corridor in October 1990, 66 months or 5.5 years after carpool utilization of the Katy HOV Lane began. The 1990 data are compared to similar data collected before carpool utilization was permitted (March 1985) and after carpool utilization was permitted (April 1986, October 1987, October 1988 and October 1989). These comparisons address numerous concerns and provide an indication of the effectiveness of allowing carpools onto the Katy HOV Lane. Also included in this report are summaries of survey data collected along the Katy, North, Northwest and Gulf Freeway/HOV Lane corridors from April 1985 through October 1990. The primary intent of these surveys was to: 1) determine perceptions of HOV lane utilization; 2) identify why commuters have chosen their present travel mode; and 3) assess attitudes and impacts pertaining to the HOV lanes. Demographic data and data concerning general travel characteristics were also collected.
