Abstract:

Most signalized conventional diamond interchanges in America operate in only one signal phasing sequence and this limits the efficacy of the signal system. The Texas State Department of Highways and Public Transportation (SDHPT) developed by 1984 an urban diamond controller that provided two phasing sequences that produce improved efficiency and reduced traffic delays over that provided by conventional controllers. Many of these controllers have been installed in the Dallas-Ft. Worth metroplex area of which Arlington is included. Traffic engineers with the City of Arlington began to experiment with innovative control ideas to provide additional phase flexibility at signalized diamond interchanges beyond the two-sequence system. This study describes the results of their development work and the quality of traffic flow provided at three interchanges studied in Arlington during the summer of 1988 by the Texas Transportation Institute.
