Problems solved by technology
[0004] Since the OD information cannot fully reflect the travel conditions of the vehicles in the traffic scene, there is a large difference between the simulated operation of the generated simulated vehicles and the operation of the vehicles in the actual traffic scene, which makes the road network simulation model after the final training inaccurate

The embodiment of the invention provides a road network simulation model construction method and device and electronic equipment, and is applied to the technical field of traffic simulation, and the method comprises the steps: determining a continuous driving path of each target vehicle based on electronic police vehicle passing data of a traffic scene; transmitting each continuous driving path to road network simulation software, so that the road network simulation software simulates and operates a plurality of simulation vehicles according to each continuous driving path in a static road network simulation model of the traffic scene; acquiring simulation state information of the traffic scene represented by the static road network simulation model when a plurality of simulation vehicles are operated in a simulation manner; if the difference between the simulation state information and the target traffic state information meets a model convergence condition, obtaining a trained road network simulation model; otherwise, adjusting traffic dynamics model parameters in the static road network simulation model, and continuing to train the static road network simulation model. According to the scheme, the accuracy of the road network simulation model can be improved.
Description
technical field [0001] The invention relates to the technical field of traffic simulation, in particular to a construction method, device and electronic equipment of a road network simulation model. Background technique [0002] Aiming at the current increasingly serious traffic congestion problem, the road network simulation model plays an important role in analyzing and dealing with complex traffic scenarios. Among them, the road network simulation model is a model for simulating the road environment and vehicle running state in the traffic scene. [0003] In related technologies, the construction process of the road network simulation model includes: obtaining OD (Origin Destination, origin and destination) information and traffic state information of pre-statistical traffic scenes, the traffic state information is used to reflect the congestion state; based on the OD information, in the static The corresponding simulated vehicles are generated in the road network simula...
