The United States Department of Transportation (USDOT), the Road Bureau of Ministry of Land, Infrastructure, Transport, and Tourism (MLIT) of Japan, and the European Union’s European Commission Directorate General for Communications Networks, Content &amp; Technology (DG CONNECT) have a long history of sharing information on ITS (Intelligent Transportation Systems) activities. A US-Japan-Europe ITS Task Force was established specifically to facilitate the exchange of information and identify areas for collaborative research for the development and deployment of ITS in the three nations. The Task Force identified the following four high-priority areas for conducting collaborative research:<br />
1. International Standards<br />
2. Evaluation Tools and Methods<br />
3. Probe Data<br />
4. Automation in Road Transport<br />
To continue the initial joint US-Japan work documented in the US-Japan Collaborative Research on Probe Data: Assessment Report [1], published in November 2013, this report documents the work conducted from the fall of 2013 through the fall of 2015 to:<br />
1. Add probe system and probe data inputs from the European team;<br />
2. Significantly expand on the initial assessment, providing an extensive expansion on assessing the three applications;<br />
3. Discuss cross-cutting issues that affect all three applications; and<br />
4. Introduce the next steps for future collaboration
