Embodiment

[0089] Based on the actual operating data of No. 11 on the new version of the intelligent dispatching system of Guiyang Public Transport Company, a comprehensive numerical simulation is carried out for a short-term dynamic dispatching method of public transport based on real-time GPS in terms of parameter design and prediction accuracy.

[0090] (1) Threshold design of equalization coefficient

[0091] The threshold value of the equalization coefficient has a crucial influence on the final result of the present invention. Judging from the actual operation of public transport, when the current line is relatively congested, the dispatcher will dispatch more frequently. At this time, the balance coefficient of the algorithm should be more sensitive, so as to adjust the departure interval in time and prevent large intervals. When the current line is relatively smooth, the dispatcher's dispatching frequency is significantly reduced. At this time, the sensitivity of the algorithm's ...

Abstract

The invention discloses a real-time GPS-based short-term dynamic dispatching method for public transport, comprising the following steps: determining the maximum line distance maxdis of two adjacent buses on the current line according to real-time GPS data, and determining Line balance coefficient λ; where the main station and auxiliary station are regarded as virtual buses to participate in determining the maximum line distance between two adjacent buses; the current line balance coefficient λ and the two preset thresholds α 1 , α 2 For comparison, when λ≤α 1 When , no adjustment is made; when α 1 <λ≤α 2 When , readjust the subsequent departure interval; when λ>α 2 , adding vehicles from the main station; the threshold α 1 The value is the line balance coefficient when the bus on the current line runs in an ideal state according to the scheduling plan and satisfies 0<α 1 <α 2 <1.

Description

technical field [0001] The invention is a real-time GPS-based short-term dynamic dispatching method for public transport, and relates to a heuristic algorithm for short-term dynamic dispatching of public transport based on an artificial neural network. Background technique [0002] In recent years, with the gradual increase of the income level of urban residents, the number of private car ownership has shown explosive growth, followed by the deteriorating urban traffic conditions and traffic congestion. How to solve the problem of traffic congestion is a severe test faced by governments all over the world. Public transportation has the advantages of large capacity, high transportation efficiency, low energy consumption, relatively little pollution and low transportation cost. Public transportation vehicles are the main carrier of public transportation and the main choice for urban citizens to travel. Therefore, vigorously developing public transportation has become a Major ...
