Abstract
Nowadays, the Internet of Vehicles has become the focus of global technological innovation and transformation in the automotive industry. Its flow modelling appears to play a very important role for designing and controlling the transportation systems, since it is not only necessary for improving safety and transportation efficiency but also can yield a series of society, economy, and ecosystem environment problems. Considering the characteristics of the frame structure includes states and actions and discrete and continuous aspects of traffic flow dynamics, both petri net and Z have proved to be useful tools for modelling the Internet of Vehicles. It can formally describe the vehicle behavior accurately with petri net and more details with Z frame structure. A new integration formal method of time petri net and Z is presented in this paper for modelling the vehicle behaviors and traffic rules through taking into account state dependencies on external rules. Moreover, a case study in the Internet of Vehicles is proposed to deal with the accurate localization of events. It shows that this formal verification methods significantly improves the safety and intelligence of the Internet of Vehicles.

Summary
With the development of communication technology, wireless sensing technology, automatics, artificial intelligence, and so on, the Internet of Vehicles techniques come out. PZN has a good advantage in describing traditional systems, since specification Z has a good frame structure both in state description. The hybrid methodology which combines the advantages of both specification Z and Petri nets is very suitable for modelling and analyzing the Internet of Vehicles system. Some researchers used time Petri nets to model the requirements and software of system [29,30,31,32,33,34], but it lacked specific rule descriptions and state depictions. Motivated by the previous experience in formal verification of requirements modelling and analyzing of networked software, in this paper, TPZN (integration Time Petri Net and Z) is proposed to formal modelling and verifying the Internet of Vehicles systems. A case study shows the modelling method in detail. is formal method is proved greatly by improving the safety and validity of the intelligent vehicle systems
