C-ITS stands for Cooperative Intelligent Transport Systems, which enable ITS-stations to interact and cooperate by exchanging secured and trusted messages. There are two channels for exchanging these messages: long-range utilizing commercial cellular networks and short-range using direct communication. In Europe, ITS-G5 technology has been most used short-range technology, but recently 3GPP's C-V2X has emerged as a potential alternative.
The objectives of this study were divided into three sections. 1) Deploy and demonstrate EU-wide EU CCMS system, 2) Test and demonstrate the operation of C-V2X (LTE-V2X) technologies defined by 3GPP, and 3) Investigate the applicability and compatibility of C-Roads platform specifications together with C-V2X technologies. To achieve these objectives, C-Roads platform specified C-ITS service was implemented at a traffic-light controlled intersection.
