Intersection Timing Method Based on Mixed Traffic Flow Delay Model

Abstract

The invention relates to an intersection timing method based on a mixed traffic flow delay model, which can obtain an approximately optimal timing scheme for a single intersection under the mixed traffic flow situation according to the characteristics of the mixed traffic flow, including: (1 ) Obtain traffic parameters at the intersection; (2) Establish non-motor vehicle dissipation model; (3) Establish mixed dissipation model; (4) Model the average delay of non-motor vehicles; (5) Obtain the average delay under mixed traffic flow; ( 6) Calculate the optimal timing cycle; (7) Calculate other parameters such as green light time. The invention uses the mixed traffic flow model to solve the timing parameters such as the optimal period of the intersection, and provides an effective timing method for the intersection timing under the mixed traffic flow condition.

Description

technical field [0001] The invention belongs to the field of urban traffic signal control, and more specifically relates to an intersection timing method based on a mixed traffic flow delay model, which can establish a mixed traffic flow dissipation model and a delay model according to the characteristics of the mixed traffic flow, and obtain Approximate Optimal Timing for a Single Intersection with Mixed Traffic Flows. Background technique [0002] With the rapid growth of China's economy and the acceleration of urbanization, a large number of people are pouring into cities. The speed of construction and improvement of transportation facilities is far behind people's growing transportation needs, and the problem of traffic congestion has become increasingly prominent. Traffic congestion not only exists in big cities such as Beijing and Shanghai, but also widely exists in third- and fourth-tier cities. Due to the constraints of economic factors and geographical environment,...

AI Technical Summary

Problems solved by technology

Traditional intersection timing methods, such as the Webster method, are obtained based on the motor vehicle delay model and do not consider the impact of mixed traffic flow, so they are not suitable for traffic conditions where non-motor vehicles have a greater impact
