Simulation and Analysis Method of Urban Traffic System Oriented to Traffic Strategy Combination

Abstract

The invention discloses an urban traffic system simulation analysis method oriented to traffic strategy combination. The method firstly combines land development and adjustment strategies, infrastructure construction strategies, traffic management and control strategies; then performs traffic impedance analysis, traffic Demand analysis and traffic distribution analysis to obtain road traffic in the urban traffic system; calculate the target value based on road traffic, and evaluate whether the target value meets the preset conditions; if the preset conditions are met, directly output the recommended traffic strategy combination; otherwise, recombine the traffic strategy , continue to analyze the traffic operation and calculate the target value until the traffic strategy combination that makes the target value meet the preset conditions is found. On the premise that multiple traffic strategies are optional, the present invention can provide reference information for urban traffic decision-making departments to rationally match traffic strategies, and has high application value.

Description

technical field [0001] The invention relates to an urban traffic system simulation analysis method oriented to traffic strategy combination, and belongs to the technical field of urban traffic system planning management and simulation analysis. Background technique [0002] In recent years, as my country's urbanization process continues to accelerate, the urban population density is increasing day by day, and the number of cars is increasing year by year. The ever-increasing traffic demand brings great challenges to the current traffic infrastructure. Urban traffic problems such as traffic congestion, traffic chaos, and energy consumption pollution caused by the imbalance between traffic supply and demand have become increasingly prominent. According to the "National Major Cities Commuting Time Consumption Monitoring Report" released by the China Urban Planning and Design Institute at the end of 2020, more than 10 million people in 36 key cities across the country are suffe...

AI Technical Summary

Problems solved by technology

[0004] Although there are a variety of traffic strategies to choose from, most of the existing research focuses on the design of a single strategy and the simulation analysis of the implementation effect, and there is little research on the combination analysis and comparative selection of multiple traffic strategies

In real life, different traffic strategies often go their own way, or even hinder each other, resulting in waste of traffic resources and affecting the effect of traffic regulation
