Method for creating Paramics road network based on XML (Extensive Markup Language) road network data

Abstract

The invention relates to a method for creating Paramics road network based on XML (Extensive Markup Language) road network data. The method comprises the following steps of: S1, analyzing the XML road network data, generating a road section link table, and traversing the road section link table to obtain a starting point coordinate, an ending point coordinate and corresponding attribute values of each road section; S2, creating a road network node link table, adopting the starting point coordinate and the ending point coordinate of each road section as node elements, and storing the node elements in the road network node link table according to serial numbers; S3, searching the related road sections of various node elements in the road network node link table in the road section link table, and generating a new road section link table according to the starting point coordinate and the ending point coordinate of the searched relevant road sections; S4, respectively generating nodes files and links files according to the road network node link table and the new road section link table; S5, using the generated nodes files and the links files to generate a road network. According to the method, large-area complex road network is created while disturbance of road network topology caused by reading errors is prevented.

Description

technical field [0001] The invention relates to the field of micro-traffic simulation, and more specifically, relates to a Paramics road network construction method based on XML road network data. Background technique [0002] Micro-traffic simulation technology can describe the environment, vehicles and other components of the traffic system and their traffic behavior in detail, and can display them dynamically in real time. This technical method has incomparable advantages compared with traditional research methods in the study of micro-traffic behavior and regional traffic control strategies. In recent years, micro-traffic simulation software has developed rapidly, among which the micro-traffic simulation software Paramics has been widely used in the field of micro-traffic simulation relying on powerful functional module groups. [0003] The basis of micro traffic simulation research using Paramics software is to establish the basic road network of the simulation object ...

AI Technical Summary

Problems solved by technology

At present, the road network is constructed mainly through the Modeller module and the Converter module that comes with the software. The Modeller module constructs a simple road network by manually drawing points and lines, but it is powerless for complex road networks in large areas; although the Converter module can realize TRIPS and SATURN Such as the conversion of the road network map format in large areas, but when using this module to construct the road network, there will be errors in reading the attributes of nodes and links, resulting in confusion in the topology of the road network
