Abstract

A macroscopic model for estimating the mean speed along urban surface streets is presented. The model captures all geometric, control, and demand conditions identified in the Highway Capacity Manual as being significant factors influencing travel time and levels of service along urban streets. The proposed model is calibrated using a combination of CORSIM, VISSIM, and SYNCHRO simulation models. Regression analyses are performed to determine the speed penalty imposed on the free flow speed resulting from each of the twelve predictor variables representing geometric, control, and demand conditions on urban streets.
