Abstract

This paper describes the development of a procedure for predicting the arrival flow profile for an intersection approach. This profile describes the variation in flow rate during the average signal cycle, as it would be measured a specified point downstream of a signalized intersection. The research indicates that platoon decay (due to mid-segment driveway access and egress) tends to have a more significant impact on the arrival flow profile than platoon dispersion. Platoon dispersion reflects drivers desireto increase their headway, while platoon decay reflects vehicles departing the platoon at mid-segment access points. The procedure is recommended for inclusion in the Urban Street Segments chapter of the forthcoming 2010Highway Capacity Manual
