Sampling-based park-and-ride facility attraction demand quantitative classification calculation method

Abstract

The invention relates to a quantitative classification calculation method for quantitatively describing the demands of different positions in an urban park-and-ride facility attraction demand range and belongs to the urban traffic planning field. The method comprises the following steps that: a virtual analysis network of a park-and-ride facility attraction demand range area is constructed according to demand point samples and geographic coordinate positions which are obtained through investigation; the distribution density of sampled demand points is calculated through using a kernel function in probability theory; and the total demand density of each position in the facility attraction demand range is calculated and classified through using an adaptive kernel density analysis theory and a numerical value superposition method. The quantitative classification calculation method can be utilized to quantitatively analyze demand intensity distribution of each point at different directions and different distances in the park-and-ride facility attraction demand range, and can classify the demands in the facility attraction demand range through the total demand density, and has a favorable role of reference in the determination and analysis on distribution characteristics of the park-and-ride facility attraction demand range, and provides a new method for park-and-ride facility demand forecast.

Description

technical field [0001] The invention relates to a quantified and graded calculation method for quantitatively describing the requirements of different locations within the range of attraction demands of urban parking and ride facilities, belonging to the field of urban traffic planning, which can be used to measure the demand intensity of each point within the range of attraction demands of parking and ride facilities , to analyze the distribution of attraction demand, and then provide a new method basis for the demand forecast of park-and-ride facilities. Background technique [0002] Park&Ride, as a mode of transportation, usually refers to the establishment of park-and-ride facilities outside the central city (or congested area), encouraging private car travelers to park there, and transfer to public transportation to enter the city center. In order to alleviate the traffic pressure in the central area of ​​the city and promote the utilization of the urban public transpor...

AI Technical Summary

Problems solved by technology

[0004] In short, the current domestic and foreign research on the attraction demand of park-and-ride facilities is mainly based on the determination of the range of attraction demand based on surveys and the trend analysis of demand changes with factors such as distance. There is no quantitative analysis of the demand for different locations within the range of facility attraction demand. Therefore, it is particularly necessary to conduct research on quantitative and hierarchical calculation methods for park-and-ride facilities to attract demand
