The fast development of automotive and transport industry has brought a series of problems,such as huge number of vehicles,high energy consumption,frequent accidents and huge economic losses,thus seeking a new way to achieve effective vehicle and traffic management is of great significance.One possible solution is to build a National Automobile Internet Infrastructure(NAII)and develop new technologies via this platform to manage vehicle and traffic efficiently. We will describe the key constituent elements of this "Internet" of mobile vehicles based on its core concepts,and deeply explore its scientific connotation.We will analyze the enormous challenges faced by NAII and focus on exploring the integration and innovation approaches for its key technologies.Based on our analysis and some existing or foreseeable typical application scenarios,we will further interpret the broad prospects and far-reaching impact in future automotive and transport industry. <<
