QoS-CITS: A simulator for service-oriented cooperative ITS of intelligent vehicles

With the emerging vehicular network and the possible diverse applications, Intelligent Transportation Systems (ITS) have been evolving to Cooperative ITS (C-ITS, CITS) with connected intelligent vehicles, and the topics in this domain also raise more and more research interesting recently. However, subjecting to the immaturity of V2X communication technology and the deployment of intelligent vehicles in large scale, such studies and the corresponding verification are all challenged within current situations. Focusing on several emerging features, such as cyber-physical fusion, vehicular networking, service-carrier etc, a new simulator QoS-CITS for such service-oriented C-ITS is designed. To enhance the adaptivity, an para-reconfigurable architecture is firstly adopted, within which all reservation-based models of traffic objects, state-driven behaviors, cooperation mechanisms, and policies proposed for service-oriented C-ITS are implemented. And then, a series of experiments are conducted via employing parameters within typical scenes, and all fundamental functions of QoS-CITS are verified. With this simulator, researchers can carry out various experiments, not only classic ones but service-oriented, via setting parameters according to their study and verification requirements, and then analyze the performance with statistics data automatically recorded.
