Введение. В статье рассматривается возможность формирования стратегии оптимизации дорожного движения на основе макроскопической фундаментальной диаграммы между городскими районами. Построены зоны притяжения при максимальном и минимальном значении пограничного контроля по категории разных типов зоны притяжения. Сформированы стабильные зоны посредством соединения зон притяжения и проанализированы изменения их формы с разными значениями экзогенного потока и эндогенного потока.

Introduction

Introduction. The article considers the possibility of forming a traffic optimization strategy based on a macroscopic fundamental diagram between urban areas. The zones of influence are constructed with the maximum and minimum values of border control, respectively, according to the category of different types of the zone of influence. The stability zones were formed by connecting the zones of influence and their shape changes with different values of exogenous flow and endogenous flow were analysed.

Materials and methods

Materials and methods. The data on the traffic flow of the central part of the Jinan (PRC) road network are presented and an urban bizonal system is constructed using the obtained macroscopic fundamental diagrams. The modelling of the state of traffic flows was carried out and the regularity of their changes at different parameters of border control was obtained using the mathematical modelling MATLAB complex.

Results

Results. As a result of the study, the traffic management solutions were obtained for the relatively parameter of completed and incomplete trips. The generalized options for optimizing traffic in the considered urban areas are proposed – four combinations of strategies for traffic management are performed serving the design optimization option with different traffic flow conditions.

Discussion and conclusions. For each multi-zone system of the road network, it is necessary to form its own characteristic variant of optimizing the traffic flow.
