Description

technical field [0001] Embodiments of the present invention relate to the technical field of data simulation, and in particular, to a traffic simulation method, apparatus, electronic device, and computer-readable storage medium. Background technique [0002] With the development of society, the holdings of motor vehicles continue to increase, and the pressure of traffic flow in traffic areas is also increasing. How to effectively alleviate the traffic pressure and how to adjust the traffic conditions in a controllable manner are urgent problems to be solved at present. Using computer technology to simulate and analyze traffic data can not only provide data support for the formulation of traffic management strategies, but also reduce the number of traffic detection devices and greatly reduce detection costs. However, most of the traffic simulation technologies in the prior art are based on the agent (agent) mode, in which the agent can represent a single individual, such as p...

Problems solved by technology

However, most of the traffic simulation technologies in the prior art are based on the agent (agent) model, wherein the agent can represent a single individual, such as pedestrians, vehicles, etc., and can also be composed of multiple individuals, such as drivers, passengers and vehicles. In actual application, the inventors found that this technology is limited by the cooperation mechanism between agents. For example, when the dynamic traffic data of an individual or several individuals in the agent are related to multiple simulation computing nodes, that is When the traffic behavior of an individual or several individuals in an agent spans multiple simulation computing nodes, due to the huge amount of communication data between the simulation computing nodes, it is difficult for the system to accurately calculate and simulate the dynamic traffic data of the agent in real time , so whenever a startup time is triggered, the simulation system based on the agent mode will traverse all agents to update their status, resulting in a decrease in simulation performance, and because the agent mode focuses on the vehicle, it cannot solve the problem of road network maintenance The problem of updating dynamic road network data, so it is only applicable to static road networks, cannot solve the problem of road network information upgrade well, and cannot meet the needs of large-scale traffic simulation
