Abstract

At signalized intersections, due to variability in vehicle types necessitates converting mixed traffic flow in to equivalent passenger car flow with a help of passenger car units. This study proposes a technique to estimate saturation flow by converting mixed traffic flow from vehicle per hour to PCU per hour by estimating the PCU values using time occupancy method during the saturated green time with different level of traffic interaction. Traffic discharge and clearance time have been extracted from the video of collected data. Regression based stream equivalency models are developed for quick and easy estimation of saturation flow.
