Quantitative method for preponderant trip distance of transportation mode based on generalized trip cost

Abstract

The invention discloses a quantitative method for a preponderant trip distance of a transportation mode based on generalized trip cost. The method comprises the steps as follows: basic parameter information such as a unit time value of residents in a city and a fuel charge are firstly acquired, the situation of the city is researched and a related parameter of a trip limitation condition of each transportation mode is determined accordingly; then an average trip consumption model, which is changed according to the trip distance, of each trip mode in the city can be acquired according to each acquired parameter; then a utility function model of each transportation mode can be acquired according to a trip consumption function; and then the utility function is corrected by taking into accountlimitation conditions such as physical power, money and energy of a traveler. Therefore, a probability density function of each transportation mode under the same trip distance is acquired, and a matlab tool is used for fitting the acquired probability density function, that is to say a preponderant trip distance function of each transportation mode is acquired.

Description

technical field [0001] The invention relates to a method for quantifying advantageous travel distances of various travel modes in a city based on generalized travel costs, and belongs to the technical field of urban road traffic planning and management. Background technique [0002] With the application of Internet + technology in all walks of life, more and more emerging travel methods appear in people's daily life. The choices are more varied. The Ministry of Transport clearly proposed to optimize my country's transportation structure and promote the construction of a comprehensive transportation system. [0003] After long-term research by the inventors, it has been found that each mode of transportation has different technical and economic characteristics and advantages, and has its unique reasonable use range under certain circumstances and conditions, that is, each mode of transportation has an advantageous travel distance. Within a certain distance range, this mode ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problem of determining the advantageous travel distance of each transportation method when multiple transportation methods coexist in the city, the present invention provides a method for quantifying the advantageous travel distance of urban comprehensive transportation methods based on generalized travel costs, which can Make up for the shortcomings of the commonly used methods of transportation, provide a reasonable basis for the formulation of construction plans that meet the needs of urban transportation development, promote the optimal allocation of resources, and realize the healthy development of urban transportation network economic benefits
