Voronoi diagram-based hybrid public bicycle scheduling demand prediction method

Abstract

The invention discloses a Voronoi diagram-based hybrid public bicycle scheduling demand prediction method. The method comprises the following steps of S1, obtaining staked and non-staked public bicycle travel data; S2, setting a scheduling area boundary; S3, drawing a Voronoi diagram based on the public bicycle stations with the piles; S4, extracting a time sequence of the travel volume of each sub-region of the Voronoi diagram; S5, determining orders p and q of the ARMA model; S6, predicting the travel volume of the next day by adopting the calibrated ARMA model; and S7, calculating scheduling time and scheduling amount in each subarea. According to the method, scheduling partitioning and demand prediction are carried out by comprehensively considering the public bicycles with piles and the public bicycles without piles, the defect that a traditional research and application method only aims at a single public bicycle is overcome, and the situation that the two kinds of public bicycles are separately operated and repeatedly scheduled is reduced; meanwhile, compared with a traditional method, the scheduling demand generated by the method is more detailed and more accurate.

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...
