THE IMPACTS OF CARPOOL UTILIZATION ON THE KATY FREEWAY TRANSITWAY 30-MONTH "AFTER" EVALUATION. INTERIM REPORT

A major commitment has been made in the Houston area to develop physically separated transitways in the medians of freeways. The lanes are reserved for high-occupancy vehicles. Phase I of the first completed transitway opened on the Katy Freeway (I-10) in October 1984. Phase 2 opened in June 1987. To increase potential utilization of this facility, carpools began using the transitway on a test basis in April 1985. This research study, funded jointly by the Metropolitan Transit Authority of Harris County and the Texas State Department of Highways and Public Transportation, was initiated to undertake a comprehensive analysis of the effects of permitting carpool utilization. This report documents the data collected in October 1987, 2.5 years after carpool utilization of the transitway was permitted. In this report, these data are compared to similar data collected both before carpool utilization was permitted and on several occasions after carpool utilization was permitted.
