Embodiment Construction

[0055] Further illustrate the present invention below in conjunction with accompanying drawing.

[0056] The estimation method of public bicycle service point traffic demand of the present invention, the steps are as follows:

[0057] 1) Virtual grid division; find an equilateral hexagon that can completely cover the research area from the area covered by the bicycle service, and connect the center of the hexagon to the six vertices with straight lines to form six equilateral triangles , these triangles are divided into virtual meshes in turn, these small virtual triangles obtained discretely are set as a unit, and the virtual triangle unit is ijk (numbered counterclockwise), i, j, k are 3 nodes, and the coordinates are respectively for (x i ,y i ),(x j ,y j ),(x k ,y k )(x is latitude direction, y is longitude direction).

[0058] 2) The loan-return function of the virtual triangular unit; the borrow-return function is

[0059]

Abstract

The method for estimating traffic demand of public bicycle service points, the specific steps are as follows: 1) virtual grid division; 2) borrowing and returning function of virtual triangular element; 3) analyzing and solving the lock ratio (α) and the unit natural demand (Funit); 4) Calculation of demand increment matrix of public bicycle unit; 5) Synthesis of public bicycle system and introduction of conditions; 6) Solving equation system. The invention makes full use of the principle of finite element analysis method, reasonably estimates the traffic demand of public bicycle service points, avoids the situation that cannot be rented or cannot be returned, and has important guiding significance for the development of public bicycles.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation systems, and in particular relates to a method for estimating the traffic demand of a public bicycle service point. Background technique [0002] Public bicycles are a new mode of transportation that is rapidly developing at home and abroad, effectively solving the problem of the last mile of public transportation. However, the estimation and deployment of public bicycle service point traffic demand has brought new challenges. At present, it is often estimated based on artificial experience, which cannot well meet people's demand for public bicycle travel. Contents of the invention [0003] The present invention overcomes the disadvantage that the prior art cannot provide the estimation and layout of the traffic demand of the public bicycle service point, and provides an effective method for estimating the traffic demand of the public bicycle service point. [0004] When stud...
