Abstract

Recent achievements of international harmonisation and standardisation of advanced communications technologies for road vehicles and Intelligent Transportation Systems (ITS) allowed the developments of complex cooperative ITS (C-ITS) solutions by paving the way of novel ITS applications emerging from proof-of-concept designs to real industrial implementations. The Internet-of-Things (IoT) is a relatively new concept of communication, by means of which everyday physical objects will be connected to a global network (i.e., the Internet) and will be able to identify themselves to other devices in a uniform way. Based on preliminary results published by the authors, this paper provides a comprehensive idea of how the concept of IoT might converge with the C-ITS field by the assessment of a combined technology and extension of the current C-ITS standards. It also presents the results of integration of the IEEE 802.15.4 networking technology and the 6LoWPAN network protocol in the architecture and operation of ITS Station Architecture. Moreover, convergence methodologies are investigated from multiple views to identify the basic principles and requirements of the new technology for harmonised C-ITS use cases and standards. Reference implementations of the proposed approaches are presented along with the detailed verification of the concept through a road-safety V2X scenario, which was implemented by the authors as part of one of the outdoor C-ITS evaluations performed at the ITS World Congress in 2012.
