Problems solved by technology

[0002] In the existing traffic flow simulation technology, the following methods are usually adopted. First, the fixed traffic flow simulation of the specified line, that is, the traffic flow movement mode and trajectory are artificially specified. This method affects the vehicle trajectory, speed, direction, turning, lane change and Actions such as parking are pre-set to make vehicles in the traffic flow move in the expected way, which is only suitable for the reproduction of specific scenarios; second, the simulation is based on the car-following model and the lane-changing model, that is, according to the distance between vehicles and the expected The speed determines the speed of the vehicle. When the distance between vehicles is greater than the distance that can be merged into, the vehicle merges into and changes lanes; obviously, the above methods have poor diversity and poor authenticity.

Abstract

The invention discloses a simulation method and device, electronic equipment and a storage medium, and relates to the field of intelligent traffic and traffic flow simulation. The specific implementation scheme is as follows: the method comprises the steps of receiving a simulation request, wherein the simulation request at least indicates to calculate the driving characteristic of a target vehicle in a specified simulation environment; determining road information based on the simulation environment specified by the simulation request, and obtaining the lane change characteristic of the target vehicle under the road information; calculating to obtain a reference driving characteristic of the target vehicle under the lane changing characteristic, wherein the reference driving characteristic at least comprises a reference speed and a reference driving direction; and selecting a target driving characteristic matched with the reference speed and the reference driving direction included inthe reference driving characteristic from a preset real traffic flow database as the driving characteristic of the target vehicle in the simulation environment. Therefore, the diversity of simulationschemes is enriched, and meanwhile, the authenticity is also improved.
