The basic objective was to identify variables that are significant to the pedestrian effect on vehicle flow through at-grade intersections. Data were collected and analyzed to determine if a statistical relationship existed between the selected variables and the vehicle-seconds of delay being caused by pedestrian-vehicle frictions as a result of both vehicular and pedestrian movements at the study intersections. The multiple-regression analysis of the data produced three regression models that should give accurate estimates of the vehicle-seconds of delay. The first model included the data for all 6 study intersections, 3 with all one-way streets intersecting and 3 with 1 one-way street and 1 two-way street connecting. The second model was applied to 3 intersections with one-way streets intersecting. The third model was derived from the data on 3 intersections with 2 one-way street legs and 2 two-ways street legs. A definite statistical relationship was found to explain the pedestrian effects on vehicle delay at typical urban intersections. /author/
