With the rapid development of information technology, there is an increasing interest in connected vehicle and related technology. Compared to the large number of simulation studies on connected vehicle, there appeared to be few empirical studies on the performance of networks and applications due to the lack of suitable hardware facilities. Therefore, Chang’an University started to build a cooperative vehicle-infrastructure system test bed with different types of ITS scenarios and communication systems such as 4G-LTE and VANET (Vehicular Ad Hoc Network), which was called CU-CVIS test bed and located in its Weishui campus. In this paper, the architecture and detailed functions of CU-CVIS test bed are presented. Firstly, some important connected vehicle test beds in the world are introduced. Next, based on the demand of applications on connected vehicle, details of CU-CVIS test bed, such as architecture of the test bed, construction of 4G-LTE and DSRC communication systems and result of performance test, are described. The characteristics of CU-CVIS test bed are also presented. Finally, the vision and developing strategy of the test bed in the future are discussed with opportunities and challenges. It can be concluded that CU-CVIS can simulate various connected vehicle scenarios with reliable heterogeneous vehicular network and support future empirical study on connected vehicle and other related technologies.
