Urban multi-mode traffic network transportation capacity coordination evaluation method

Abstract

The invention discloses an urban multi-mode traffic network transportation capacity coordination evaluation method. Firstly, an urban multi-mode traffic network is used as a research object; the overall service level of the network is balanced, and all sub traffic networks are matched with one another; then, based on the supply and demand characteristics of the urban multi-mode traffic network, atopological structure and a road section impedance function of the urban multi-mode traffic network are constructed; and a random user equalization model is adopted to allocate and solve the passengerflow of each sub-traffic network in the urban multi-mode traffic network, and a single network service level, a traffic network Gini coefficient and a demand proportion between traffic modes are selected as an evaluation system of the transport capacity coordination level of the urban multi-mode traffic network. On the basis of fully considering supply characteristics and state attributes of theurban multi-mode traffic network, a scientific and effective theoretical method is applied to analyze and evaluate the passenger flow distribution state of the urban multi-mode traffic network, so that the operation state of the whole urban multi-mode traffic network achieves the optimal effect.

Description

technical field [0001] The invention relates to the field of urban traffic planning and management, in particular to a method for coordinating and evaluating the transportation capacity of urban multi-mode traffic networks. Background technique [0002] With the development of rapid urbanization, the scale of cities continues to expand, and the total traffic demand, average travel distance and time increase significantly. constitute the stages of development of the multimodal transportation network. "Multi-mode travel demand and multi-mode network supply" has become the main trend of China's urban comprehensive transportation development. The urban multi-modal transportation system has high complexity in terms of network supply performance, travel behavior decision-making, traffic demand and supply balance, and resource collaborative planning and allocation. As the supply facility of urban transportation, the urban multi-modal transportation network structure has an import...

Problems solved by technology

[0003] In recent years, the urban multi-modal transportation network based on "walking connection network, urban road network, conventional bus line network and subway rail network" has begun to take shape, forming a network of "cars, conventional buses, subways, conventional buses + subways, It is a typical commuting mode based on five modes of travel: car + subway. However, various transportation networks lack efficient connection and coordination, and the potential ability to serve diverse travel needs and complex traffic flow operation and transformation has not been fully utilized, and it is difficult to actively guide travel.
