Abstract:
This report documents the activities of an 11-month research project that considered various pedestrianrelated factors and developed revised warrants for the installation of a traffic signal that are more sensitive to pedestrians and cyclists.|Three warrant recommendations were made as a result of this research. The recommendations are summarized below with the warrants that are affected for each recommendation. The research shows that results from warrant analyses with the revised warrants better match professional engineering judgment than the results of warrant analyses using the current warrants. The warrant recommendations should not be used until they are officially adopted by the Texas Department of Transportation.|Include pedestrians and cyclists in the minor-street approach volumes for all warrants that currently consider only vehicles for the minor-street approach volumes (Warrants 1, 2, 9, 10, 11, and 12).|Include a 30 percent volume reduction factor in the above warrants based upon the presence of certain types of pedestrian trip generators such as medical facilities, pedestrian transportation facilities, and activity centers serving pedestrians (Warrants 1, 2, 3, 9, 11, and 12).|Change the existing pedestrian warrant to a mid-block only pedestrian crossing warrant, remove language about pedestrian crossing speeds, and add a reduction factor for high-speed roadways or built-up areas (Warrant 3).
