A demand forecasting method for hybrid public bicycle dispatching based on voronoi diagram

Abstract

A hybrid public bicycle dispatching demand prediction method based on Voronoi diagrams, comprising the following steps: S1, obtaining public bicycle trip data with and without docks; S2, setting dispatching area boundaries; S3, drawing Voronoi diagrams based on public bicycle stations with piles; S4. Extract the time series of trips in each sub-area of ​​the Voronoi diagram; S5. Determine the order p and q of the ARMA model; S6. Use the calibrated ARMA model to predict the next day’s trips; S7. Calculate the scheduling time in each sub-area and Scheduling volume. The method of the present invention comprehensively considers the public bicycles with piles and pileless public bicycles for dispatching partitions and demand forecasting, breaks the disadvantages of the traditional research and application method only for a single public bicycle, and reduces the situation that the two types of public bicycles operate separately and repeatedly dispatch; at the same time , the scheduling requirement generated by the method of the invention is more detailed and accurate than the traditional method.

Description

technical field [0001] The invention relates to the fields of urban public bicycle dispatching and shared bicycles, and relates to a Voronoi diagram-based hybrid public bicycle dispatching demand forecasting method. Background technique [0002] As a low-carbon and environmentally friendly way of travel, public bicycles have been favored by the majority of travelers, and have been promoted on a large scale in many cities in my country in recent years. However, one of the most prominent problems of public bicycles at present is the "unbalanced distribution of vehicles", that is, public bicycles are often piled up in large numbers in some areas, while they are very scarce in other areas, which has caused great distress to commuters. Therefore, public bicycle operators need to regularly dispatch bicycles to achieve space rebalancing. In our country, there are two types of public bicycles, with and without piles. The two forms of public bicycles influence each other but work in...
