Queue Lengths Produced by the New Synchronized and Milwaukee B Interchanges Compared to Existing Designs
Publication: International Conference on Transportation and Development 2020
ABSTRACT
The main objective of this research was to estimate the maximum queue lengths generated by two new designs, including synchronized and Milwaukee B interchanges, in comparison to four existing designs. The methodology consisted of three main parts: (1) building a simulation model calibrated to the geometric features of 30 existing service interchanges; (2) running over 1000 simulation tests using VISSIM and Synchro; and (3) conducting two-way analyses of variance (ANOVAs) on simulation outcomes. Queue lengths were measured for many combinations of traffic volume, turning traffic percentage, traffic distribution, and traffic composition. Based on the results, the Milwaukee B design had the shortest mean queue lengths among all the interchanges considered in this study. The Milwaukee B had queue lengths averaging about 68% shorter than a parclo B interchange, which was the design with the shortest mean queue length among conventional designs. The synchronized and the DDI had similar mean queue lengths.
