ADAPTATION OF THE TRAFFIC SIGNAL CONTROL DESIGN METHOD TO A HAMBURGER ROUNDABOUT

Abstract

Introduction: Currently, hamburger roundabouts with traffic signal control have limited application in the road networks of large cities. During analysis of scientific and technical literature, we established that it does not contain any systematic information on the possibility of their application or methods to determine their parameters. Purpose of the study: We aimed to adapt Webster’s method of traffic signal design to hamburger roundabouts with traffic signal control, considering the specifics of traffic management. Methods: In the course of the study, we used methods of traffic analysis and simulation in the field-proven Aimsun software, recommended for use by scientific and technical literature on traffic management. We also assessed the efficiency of the adapted method by using the simulation results and comparing average transport delays at intersections considering the standard and adapted methods. Results: It was established that the adapted method of traffic signal cycle design reduces the average transport delay by 28% on average.
