Interaction Steady State Transportation Network and Planning Optimization Model

This paper studies the relationship among flow, density and speed of steady-state traffic network. Taking the inner ring road in Shanghai as an example, the relationship model of three parameters of traffic flow is verified, and the evaluation criteria of traffic conditions are given by three parameters. Based on the three-parameter relationship model of traffic flow, combined with the law of vehicle conservation, the macroscopic steady flow is derived. In addition, the service traffic volume and traffic resistance are selected as the objective function to establish the optimal planning model to achieve the maximum service traffic volume or the minimum traffic resistance. The establishment of the above model provides a new statistical reference value for the driverless car sharing road with private cars and the emotional interaction between the human and the automobile in the era of intelligent Internet of things.
