Traffic simulation method and device, computer equipment and storage medium

Abstract

The invention relates to a traffic simulation method and device, computer equipment and a storage medium. The method comprises the following steps: based on initial mesoscopic simulation road condition data and simulation requirements corresponding to a current time period, performing mesoscopic traffic simulation on a target vehicle corresponding to a target travel matrix of the current time period to obtain target driving data of the target vehicle in the current time period, determining the initial mesoscopic simulation road condition data according to the real-time microscopic simulation road condition data of the previous time period corresponding to the current time period; based on the target driving data, conducting microscopic traffic simulation on driving vehicles in the simulation road network corresponding to the initial mesoscopic simulation road condition data, obtaining real-time microscopic simulation road condition data corresponding to the current time period, wherein the real-time microscopic simulation road condition data are used for obtaining the simulation traffic road condition of the current time period corresponding to the simulation requirement. By adopting the method, smooth transition can be ensured during simulation transformation of two adjacent batches.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a traffic simulation method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, traffic simulation technology appeared. Traffic simulation refers to the use of simulation technology to study traffic behavior, and it is a technology that tracks and describes the changes of traffic movement with time and space. [0003] In traditional technologies, traffic simulation is run in batch cycles with a certain granular time window. When the next simulation starts, the current simulated vehicles that are still on the way will be cleared, and then the simulation will be restarted based on the newly generated traffic OD matrix, which will eventually lead to the phenomenon that the vehicles flicker, disappear and discontinuously appear when two adjacent batches of simulation are switched.
