Relationship between roadway design (geometric parameters) and flow characteristics in evaluating performance of conventional roundabout

Abstract

This paper evaluates the relationship between Roadway Design (Geometric Parameters) and Flow Characteristics under variance range of volume at the weaving area of conventional roundabout. A weaving section of roundabout was investigated and collected from the traffic video recording devices. Previously, the data capture and reduction was made and regressions analysis of data transformation is used to develop the Weaving Section Flow (Qwsf) model as a New Research Method using MINITAB software and the model developed was tested successfully for its validity and sensitivity analysis. Finally, the relationship of Roadway Design (Geometric Parameters) and Flow Characteristics were performed and elaborated through this study.
