Problems solved by technology

Dispatching management mainly relies on manpower, and the operation plan is formulated based on the experience of bus dispatching managers, and the overall technology is still relatively backward
Under such circumstances, the traffic flow on the road increases during the peak period, and the speed of the vehicles slows down, which is likely to cause traffic congestion. In addition, the number of buses on each line is limited, which will easily cause vehicle outages and traffic jams

Embodiment Construction

[0030] 1. Overall design

[0031] The overall design concept of the present invention is: through relevant mathematical models, predict bus passenger flow and travel time between stations, and realize the generation of a peak period scheduling method that changes with passenger flow and travel time. Firstly, the line passenger flow based on the bus swiping card data and the analysis method of the travel time based on the bus GPS data are described, and then the improved gray Markov model for the station passenger flow prediction and the bus travel time based on the BP neural network based on the L-M algorithm are established. The prediction model is used to analyze the road congestion according to the predicted travel time results; finally, the bus departure interval model is established and a reasonable and effective peak-hour scheduling method is proposed. figure 1 is the overall flow chart.

Abstract

The invention introduces a prediction method for a station passenger flow and inter-station journey time. The method comprises the following steps that: establishing a station passenger flow prediction model; establishing an inter-station journey time prediction model; establishing a bus departure interval model; and finally, on the basis of the passenger flow prediction model and the inter-station journey time prediction model, solving the bus departure interval model so as to realize the dynamic scheduling of buses.

Description

technical field [0001] The invention relates to a bus scheduling method, in particular to a dynamic scheduling method based on bus passenger flow and inter-station travel time prediction. Background technique [0002] The public transportation system is the main carrier of urban passenger transportation. It has a wide range of services, low cost and high efficiency, energy saving and low carbon. It is closely related to the formation, development and rise and fall of a city. important sign. However, as the urban population continues to grow, the traffic demand is uneven in time and space, making it difficult for the existing public transport system to meet people's travel needs. At present, the service level of urban public transport in my country is still at a relatively low level. The backward dispatching level of public transport is one of the fundamental reasons for the backward quality of public transport services. The bus scheduling method is simple, the technology ...
