Samenvatting
Many traffic engineering models use the length of vehicular delay as a primary measure of effectiveness for intersections. A problem with using delay as a criterion for rating intersection effectiveness, however, is that drivers probably evaluate delay differently at different types of intersection control. The purpose of this study is to present the methodology and findings of an undergraduate study at the University of Pretoria on the relative importance of delay in affecting driver levels of satisfaction at different types of intersection control. Although the results are preliminary, they tend to support measures of effectiveness currently used by the Highway Capacity Manual. (A)
