Problems solved by technology

The editing work is completely manual, and the road data information in the existing road construction drawings and engineering drawings cannot be reused. Therefore, the entire process of editing the simulated road network is time-consuming and laborious, and the degree of automation is not high, and the existing road data cannot be used

Abstract

The invention relates to a system and method for constructing traffic simulation road network data, belonging to the technical field of traffic simulation. The system and method for constructing traffic simulation road network data are characterized in that the operation is easy, the manual edition workload is simplified, the ability to generate the road network automatically is enhanced, and theadaptability is strong. The technical scheme adopted comprises that the completed road layer data is automatically cut into different road sections, and the road sections and the intersection type aredefined through manual interaction; then the road section information including the road number, road name, road type, road length, road width and the lane number and the like is constructed throughthe information such as the road center line, the lane boundary line and the lane width; the lane turning and communication relationship in different road sections are edited through manual interaction, and auxiliary information such as emergency stop distance, lane change distance and the like is added to automatically generate intersection information, associate different road sections, and construct a simulation road network logically. The system and method for constructing traffic simulation road network data have the advantages of being widely used in the simulation construction of traffic.

Description

technical field [0001] The invention relates to a system and method for constructing traffic simulation road network data, belonging to the technical field of traffic simulation. Background technique [0002] Traffic simulation is a mathematical model that describes the real-time movement of the transportation system during a certain period, and provides an important tool for studying complex traffic problems. The road network is the skeleton of the traffic system, and the accuracy of the description of the road network will have an impact on the traffic simulation effect. The current mainstream VISSIM, TransModeler and Paramics traffic simulation software all provide road network editing tools, adopting "node-arc", "line connection" and other methods to define the simulated road network structure. However, the current mainstream VISSIM, TransModeler and Paramics traffic simulation software all provide road network editing tools and have independent file formats. It is nec...
