Abstract

A survey technique for the measurement of the performance of signalized intersections is described. The technique is simple to perform in the field and produces the following types of information: (a) vehicle delay and its variability, (b) pedestrian delay and its variability, (c) vehicle flow rate, (d) total number of effective vehicle stops, and (e) a complete record of signal phasing and timing. Details are given for implementation of the technique as a conventional field survey, an "instant analysis" field survey, or a simulation model subprogram. The use of the survey technique in the evaluation of schemes for bus priority signalization is also discussed.
