Abstract

The invention discloses an SUMO traffic simulation scene accurate construction method based on data conversion. The method is based on existing actual measurement road network data and a lane level road network model. Data conversion, self-organization and reprocessing are carried out on basic object element information forming SUMO road network sub-files, a relevant conversion tool is combined, effective and available SUMO road network files are created and generated and used for SUMO simulation, and therefore accurate construction and control of a simulation scene are achieved. According tothe method, the problems of road network topological structure errors, low execution efficiency and the like caused by complex data formats and complex workloads after conversion processing are solved.

Description

technical field [0001] The invention relates to the technical field of traffic simulation, in particular to a method for accurately constructing a SUMO traffic simulation scene based on data conversion. Background technique [0002] As an open-source microscopic traffic simulation software, SUMO can support external data in multiple formats because of its scalability and high compatibility. However, the following problems exist in the construction of traffic simulation scenes by applying it at present: 1. Different types of external road network data such as OSM map data, VISSIM, MATSim, etc. have various object elements, which are relatively complex, and further editing is still required after direct import and conversion. Processing, for large-scale and complex simulated road networks, the workload is heavy and very complicated; 2. Due to the limitations and constraints of external data sources, formats, and naming rules, the imported data types cannot well meet the person...
