Development of Reliable Models of Signal-Controlled Intersections

Abstract

The paper considers an approach to building various mathematical models for homogeneous groups of intersections manifested through the use of clustering methods. This is because of a significant spread in their traffic capacity, as well as the influence of several random factors. The initial data on the traffic flow of many intersections was obtained from real-time recorders of the convolutional neural network. As a result of the analysis, we revealed statistically significant differences between the groups of intersections and compiled their linear regression models as a basis for the subsequent formation of generic management decisions. To demonstrate visually the influence of random factors on the traffic capacity of intersections, we built distribution fields based on the fuzzy logic methods for one of the clusters consisting of 14 homogeneous intersections. Modeling was based on the Gaussian type of membership functions as it most fully reflects the random nature of the pedestrian flow and its discontinuity.

Forecasting the Amount of Traffic-Related Pollutant Emissions by Neural Networks

“…An important component of urban air quality engineering is trafficrelated emission management, which depends on the number and type of vehicles and their dynamic performance indicators (Wen et al, 2019;Kelp et al, 2020;Glushkov and Shepelev, 2021). According to international methodologies and approved standards (Ntziachristos et al, 2009;garantru, 2019;GOST R 56162-2019GOST R 56162- , 2019, the amount of emissions is primarily determined by the amount, type, and nature of traffic flows (Equation):…”

Evaluation of the orderliness of the road safety provision systems in Russian cities

“…Today, it is hard to find road areas with traffic lights, working in the two-phase mode, in the biggest Russian cities (Makarova et al, 2017). Four-, five-, and six-phase traffic light modes have become more and more common for Russians (Gorodokin et al, 2017;Makarova et al, 2020;Glushkov and Shepelev, 2021;Shepelev et al, 2022).…”
