Embodiment Construction

[0054] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the above technical solutions will be further described below in conjunction with the illustrations.

[0055] As shown in the figure, a congestion traffic network balancing method based on the mixed traffic flow of electric vehicles and internal combustion locomotives includes the following steps

[0056] Step 1: Build an abstract traffic network.

[0057] There are multiple paths from the starting point r to the destination point s, and each path is composed of several interconnected road sections, and the total number of people traveling between the starting point and the destination point rs is known. use here figure 2 A simple traffic network with only one origin and destination is described to describe the specific implementation process of the present invention, and the necessity of considering mixed traffic flow in the network is illust...

Abstract

An electric automobile and diesel locomotive mixed traffic flow-based jammed traffic network equilibrium method disclosed by the present invention comprises the steps of firstly converting an actual mixed road network into the abstract nodes and road section networks, constructing a traffic distribution model considering a conventional internal combustion automobile and electric automobile mixed travel mode, and solving the model by a gradient projection algorithm to obtain a conventional internal combustion automobile and electric automobile mixed travel network equilibrium mode and the roadsection traffic flow, thereby accurately analyzing the influence of the electric automobiles on the road network and analyzing how to adjust the road section traffic flow.

Description

technical field [0001] The invention relates to a method for balanced distribution of traffic volume. Background technique [0002] Data show that my country's peak oil output will remain at 200 million tons for a long time to come, but China is a big oil consumer. In 2016, my country's apparent oil consumption was 556 million tons. my country's existing sources of oil imports are mainly concentrated in areas with many wars or international disputes such as the Middle East and Africa, which has led to an extremely unstable state of my country's oil-based energy consumption model. A significant portion of all petroleum consumption is due to transportation by conventional internal combustion vehicles. In recent national energy policy formulation and public discussions, new energy vehicles represented by electric vehicles are considered to be one of the most effective ways to reduce the dependence of transportation activities on petroleum energy. On the other hand, electric v...
