VISSIM Calibration of Roundabout Traffic Performance

Open publisher page 5 citations

Abstract

More realistic and accurate traffic simulation of two-lane roundabouts is needed. Accurate traffic simulation will support reliable traffic analysis for isolated roundabouts as well as road networks that combine signalized and unsignalized intersections and their interaction. Three existing two-lane roundabouts were studied to obtain data for reliable calibration of the VISSIM micro-simulation software. Data were differentiated by interior and exterior lanes for both entry and circulatory lanes of the roundabout. Multiple parameters in VISSIM were studied to obtain more realistic results including temporal gaps between vehicles, speed profiles (approaching and circulating speed), and car following model parameters.
