Abstract
Cooperative vehicle systems are developed in many forms, such as in-vehicle systems from different vehicle manufacturers or aftermarket devices provided by third parties, using either 3G cellular communication or G5 vehicle ad-hoc networking communication. The traffic industry develops different roadside units and a variety of interfaces to legacy roadside systems. The behavior of cooperative systems is inherently more complex than that of the individual systems alone due to the interactions of the cooperative applications, and differences in sensing and communication devices, communication media etc. Technical evaluation of the correct, safe and reliable operation of these systems and ultimately the verification and validation thereof, is a necessity for efficient, clean and safe traffic. A permanent test site for cooperative systems will facilitate the development and deployment of cooperative systems. It allows assessing the quality and performance of cooperative systems, to ensure interoperability, and to determine their impact for a more efficient, cleaner, and safer traffic environment. This paper presents the methodology and infrastructure of the DITCM test site for technical evaluation, and shows field test results that motivate further standardization of applications and basic technology. The design and implementation of the DITCM test site will be described, and how it is used as an innovation environment focused on improving the quality of cooperative systems and on facilitating a rapid deployment of these systems.
