Abstract

The invention discloses a traffic demand prediction method and device, and electronic equipment. The method comprises the steps of obtaining a trip chain of each target trip crowd in a target area; generating a model based on the trip chain and the trip data, and generating predicted trip data of each target trip crowd; determining a traffic distribution result of the target area based on the predicted travel data of each target travel crowd; if the traffic distribution result does not meet a preset convergence condition, calculating traffic comprehensive impedance according to the traffic distribution result, obtaining updated predicted travel data of each target travel crowd by combining the traffic comprehensive impedance, and obtaining an updated traffic distribution result based on the updated predicted travel data of each target travel crowd; and if the traffic distribution result or the updated traffic distribution result satisfies a convergence condition, outputting a traffic demand prediction result in the target area, the traffic demand prediction result including predicted travel data and the traffic distribution result. The accuracy of the travel demand prediction result can be improved.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a method for predicting traffic demand, a device for predicting traffic demand, electronic equipment, and a computer-readable storage medium. Background technique [0002] Urban transportation demand forecasting mainly predicts the future based on the past and current status of the transportation system and its external systems, combining historical experience, objective data and logical judgment, the process of the development law and future trend of the transportation system. It is not only a forecast of the future, but also a decision-making, that is, it is necessary to explore and grasp the future development law of traffic demand, and to correctly guide and reasonably control future traffic demand based on existing resource conditions. Traffic demand forecasting is an important part of urban traffic management planning, and the accuracy of its r...
