Because the Katy Freeway transitway is the first of a 70-mi network of transitways to be retrofitted in an existing high-volume freeway cross section in Houston, it is important to assess the traffic impacts associated with this type of construction. Operational impacts studied include travel speeds as a measure of travel time delay, traffic volumes as a measure of travel demand served, and lane distributions as a measure of driver reaction to reduced lane widths and restricted lateral clearances. Safety was assessed through an analysis of reported accidents associated with various work area segments and time periods of construction. Results indicate that a detailed traffic control plan can minimize the possible adverse effects of transitway retrofit construction.Read More
