AI Technical Summary

Problems solved by technology

MATLAB and PARAMICS themselves cannot directly exchange data, while the inter-process communication and message passing technology of WINDOWS or the mixed programming technology of MATLAB and C / C++ are more complicated to implement, and have little connection with traffic simulation

Abstract

The invention provides a data exchange method, based on file sharing, between a PARAMICS software plug-in program and a MATLAB program; the PARAMICS software plug-in program and the MATLAB program can exchange data through the file sharing, so reading-writing of the sharing file can be respectively realized according to a sharing sign value.

Description

technical field [0001] The invention belongs to the field of traffic simulation, and in particular relates to a PARAMCIS and MATLAB data interaction method and equipment based on file sharing. Background technique [0002] The application of intelligent transportation system can improve traffic conditions, and traffic simulation is an important part of intelligent transportation system, which can evaluate and estimate the system and provide a scientific basis for the selection of traffic control algorithms. PARAMICS is a leading micro-traffic simulation software with a dynamic 3D visualization user interface, supporting the simulation of 1 million intersections and 32,000 communities, aiming to design an economical, efficient, driver- and pedestrian-friendly traffic system. PARAMICS software itself provides API functions for users to carry out secondary development. Users can call API functions through C / C++ language to develop plug-in programs, and then compile plug-in prog...
