ESTIMATING QUEUE LENGTHS BY USING SIGNAL94, SYNCHRO3, TRANSYT-7F, PASSER II-90, AND CORSIM

A variety of programs are available to aid transportation engineers in their evaluation of signalized intersection operations. One measure of effectiveness--queue length--is examined. The methods used to estimate queue length, which often are not readily available, are documented for five programs; the definition used by each is clarified; and the queue length estimate of each program is compared with field data from six intersections in Denver, Colorado. Of the programs studied, three produced reasonable results 70 to 85% of the time -- CORSIM, TRANSYT-7F, and SIGNAL94. PASSER II-90 results are reasonable 50% of the time. SYNCHRO3 produces reasonable results 50% or 85% of the time, depending on the queue estimation desired. The queue length estimates for high, medium, and low volume-to-capacity ratio conditions, for all programs, are also documented.
