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.

Highlights

Hamburger roundabouts with traffic signal control have limited application in the road networks of large cities
Hamburger roundabouts with traffic signal control have limited application in the road network of such cities as Fairfax (USA), Minsk (Belarus), Samara (Russia), and some others. Such a transport junction is intended to ensure traffic management by giving priority to those moving in the main direction, allowing them to go through the central island
The traffic flow intensity values and data on the traffic signal control cycles were introduced in the traffic model; transport delays were determined for each approach; the average transport delay at the intersection was determined;

Summary

Introduction

Hamburger roundabouts with traffic signal control have limited application in the road networks of large cities. Keywords Traffic, hamburger roundabout, transport delay, traffic signal cycle. In the case of signalized roundabouts, traffic flows approaching the intersection pass it at a green light (as in the case of standard intersections), and left-turning traffic flows move simultaneously with those moving straight ahead.
