North Freeway Transitway: Evaluation of the Second Year of Barrier-Separated Operation (339-12)

This report documents the second year's operation of the I-45 North Freeway Transitway in Houston, Texas. The second year covers the period from December 1985 to November 1986. A detailed discussion of the construction sequencing and traffic control strategies implemented is also presented. Impacts to the freeway mainlane traffic are assessed through an analysis of travel times and speeds, vehicle and passenger flow rates, and freeway accident rates. Transitway operation is assessed through an analysis of high-occupancy vehicle demand volumes and peaking characteristics, park-and-ride volumes, travel time savings, occupancy rates, violation rates, disabled vehicle incident rates, and a variety of other performance measures. Comparisons are made for the second year of transitway operation with that of the previous year.
