A STUDY OF THE EFFECTS OF DESIGN AND OPERATIONAL PERFORMANCE OF SIGNAL SYSTEMS -- FINAL REPORT

This report presents the findings of a research project entitled "Effects of design on Operational Performance of Signal Systems" sponsored by the State Department of Highways and Public Transportation in Texas in cooperation with the U.S. Department of Transportation, Federal Highway Administration Areas covered include the following: peaking characteristics of volumes at intersections in Texas during rush hour traffic conditions, left turn capacity of an approach having no protected signal phasing as related to opposing traffic volumes and intersections of different geometric design, effects of signal phasing and length of left turn bay on intersection approach capacity, and development of a new field evaluation technique for signalized intersections. In addition, research was conducted to improve the Department's PASSER-II signal progression program. Platoon movement along an arterial street and the effects of progression on vehicle delay are investigated. /FHWA/
