Embodiment Construction

[0030] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0031] The present invention provides a method for quantifying the superior travel distance of urban comprehensive transportation modes based on generalized travel costs. By quantifying the travel consumption of each transportation mode under the same travel environment and travel distance, the consumption of travel time, money, etc. is uniformly represented by cost. Conditions such as traveler's physical strength restriction and travel vehicle fuel restriction are added, and the advantageous travel distance model of each mode of transportation is proposed, so as to determine the advantageous transportation range of each mode of transportation in the urban comprehensive transportation network.

[0032] Taking the urban area of ​​Nanjing City, Jiangsu Province as an example, the travel distance range of common transportation modes in the city is ...

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 ...
