VISSIM and MATLAB based internet-of-vehicle simulation platform construction method

Abstract

The invention discloses a VISSIM and MATLAB based internet-of-vehicle simulation platform construction method, including the steps of simulating vehicles through the VISSIM, saving a road network to astorage directory, registering a VISSIM COM interface object in the VISSIM, creating a VISSIM COM service interface in the MATLAB, loading the road network and setting simulation parameter through the MATLAB according to the road network storage directory, acquiring information of traffic objects in real time through the MATLAB, calculating traffic model optimization results and feeding the results to the VISSIM, performing optimization control to the traffic objects through the VISSIM according to the optimization results. By the method, the internet-of-vehicle simulation platform can be constructed rapidly while various algorithms in the environment of the internet-of-vehicle can be realized, workload in programming is reduced greatly, and meanwhile, effects of various traffic models and algorithms can be tested; therefore, the method has high practicability and has a great significance in development of various intelligent traffic models and control algorithms in future.

Description

technical field [0001] The invention belongs to the technical field of traffic engineering, and in particular relates to a method for constructing a vehicle networking simulation platform based on VISSIM and MATLAB. Background technique [0002] With the development of Internet of Vehicles technology (vehicle-road coordination, vehicle-vehicle coordination), conditions have been created for the collection of richer and more comprehensive traffic information. The Internet of Vehicles technology can not only collect vehicle position and speed information in real time, but also collect output data of traffic signal control, including vehicle delays and queuing information, through wireless communication between roadside facilities and vehicle-mounted devices, and between vehicles and vehicle-mounted devices. , which provides an opportunity for the development of dynamic timing methods for traffic signals. At the same time, research on various new traffic models related to the ...
