Abstract

The invention discloses an SUMO and UNITY joint simulation traffic network method and system, and the method comprises the steps: building a three-dimensional twin scene corresponding to a road network used by an SUMO simulation program through employing Unity, placing three-dimensional twin vehicles in the scene, and carrying out the call of functions of vehicle positions, attitudes and traffic light states in a function library TraCI.NET in the Unity scene; and updating the phases of the traffic lights and the positions and postures of the three-dimensional twin vehicles in the three-dimensional twin scene by using information returned by the SUMO simulation program, thereby achieving a three-dimensional effect of SUMO traffic simulation. According to the method, Unity is selected to make a three-dimensional twin simulation scene, and the defects of SUMO in the aspect of three-dimensional display are overcome; the powerful three-dimensional graphic function of Unity and the powerfulmicroscopic traffic simulation function of SUMO are combined, microscopic traffic can be conveniently simulated, and the simulation effect can be visually seen.

Description

technical field [0001] The invention relates to the technical field of traffic simulation, in particular to a SUMO and UNITY joint simulation traffic network method and system. Background technique [0002] SUMO is an open source microscopic traffic simulation software. Using this software for simulation requires writing three files: (1) road network file - this file can be generated using the road network editor that comes with the software, or converted from other maps such as OSM; (2) traffic flow information File—the departure time of the vehicle and the driving route of the vehicle in the road network file need to be defined in this file; (3) Simulation configuration file—the road network file and traffic flow information file used for simulation need to be specified in this file. Once you have the above three files, you can run a traffic simulation, which allows you to see traffic conditions such as current traffic flow down the road network and congestion. [0003] ...
