A Traffic Network Equilibrium Calculation Method for Satisfying Travel Endurance Requirements

Abstract

The invention provides a traffic network balanced calculation method used for satisfying a trip cruising requirement. Under the condition that an energy charging station exists in a road network, a traveler selects paths of a formed full path, a subpath, a pure subpath, a feasible subpath and the like, on this basis, a traffic network balanced model satisfying the trip cruising requirement is constructed, and a vector projection method is adopted in combination with a distance for satisfying the cruising requirement to limit the shortest path algorithm so that the model can be solved. The model can be solved, so that a flow distribution condition after the energy charging station is laid in the network is obtained, in an initial developmental stage of charging vehicles, the investment in construction of the energy charging station is large, according to the traffic network balanced calculation method used for satisfying the trip cruising requirement, powerful quantitative tools for network evaluation after planning and laying of the energy charging station can be provided, and a basis is provided for scientifically, reasonably and optimally selecting laying sites of the energy charging station.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a traffic network balance calculation method for meeting travel endurance requirements. Background technique [0002] With its advantages of zero greenhouse gas emissions, clean energy with low production costs and low noise, new energy vehicles have become a powerful weapon to solve my country's environmental pollution and over-exploitation of resources. And my country's electric vehicle industry and the use of electric vehicle systems have also entered the ascendant stage. While the large-scale application of electric vehicle technology, there are many theoretical and practical problems that need to be studied and solved. [0003] Traffic scholars often build and solve corresponding models based on some assumptions about traveler behavior, so as to allocate the demand between any two points in the urban network to the road, and obtain the traffic flow v...
