Quality Of Traffic Flow On Urban Arterials Phase I

The report identifies measures of effectiveness (MOE's) for quality of flow in urban arterial streets and describes a series of studies which will lead to the development of models which will predict values of the MOE's from roadway, traffic, and environmental characteristics. The specific measures of effectiveness are: travel time, intersection stops, intersection delays, travel time variance, and service volume. Studies include a so-called "basic" study which will use a carefully controlled sample of urban arterial segments drawn from 22 urban areas of varying sizes. An additional sample of intersections will be drawn from eight small urban areas. Supplementary special studies address the influence of heavy vehicles and grades, parking, left turns through oncoming vehicles and pedestrians and weaving maneuvers near interchanges.
