Embodiment Construction

[0055] The present invention will be further explained below in conjunction with the drawings.

[0056] The method for estimating the traffic demand of a public bicycle service point of the present invention has the following steps:

[0057] 1) Virtual grid division; find an equilateral hexagon that exactly covers 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 , Perform virtual meshing of these triangles in turn, and set these discrete virtual triangle regions as a unit, set the virtual triangle unit as ijk (counterclockwise sequence number), i, j, k are 3 nodes, and the coordinates are respectively Is (x i ,y i ),(x j ,y j ),(x k ,y k ) (x is the latitude direction, y is the longitude direction).

[0058] 2) The borrow and return function of the virtual triangle unit; the borrow and return function is

[0059] s = a 1 + a 2 x + ...

Abstract

The invention discloses an estimation method for a traffic demand of a public bicycle service point. The estimation method specifically comprises the following steps of 1) dividing virtual grids; 2) virtualizing a borrowing and returning function of a triangular unit; 3) analyzing to solve a bicycle lock ratio ([alpha]) and a unit natural demanded quantity (Funit); 4) performing incremental matrix calculation for a public bicycle unit demand; 5) synthesizing and introducing conditions for a public bicycle system; and 6) solving an equation set. According to the estimation method for the traffic demand of the public bicycle service point, the traffic demand of the public bicycle service point is estimated reasonably by fully utilizing a principle of a finite element analysis method, the situations that bicycles cannot be borrowed or cannot be returned are avoided, and guiding significance is achieved for development of public bicycles.

Description

Technical field [0001] The invention belongs to the technical field of intelligent transportation systems, and specifically relates to a method for estimating the traffic demand of a public bicycle service point. Background technique [0002] Public bicycles are a rapidly developing new mode of transportation at home and abroad, effectively solving the problem of the last mile of public transportation. However, the estimation and deployment of public bicycle service points have brought new challenges. Currently, estimates are often based on manual experience, which cannot well meet people's needs for public bicycle travel. Summary 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 studying the mechanics of the planar thin pla...
