1. Introduction
Intelligent Transport Systems Division isconducting the collaborative research with USand EU in ITS (Intelligent Transport Systems)
field. Between Japan and US, we have had theworkshop with Department of Transportation
every year since 1993 and Japan-US task force
meeting comprised of practitioners was set upin 2009 and is held several times a year.
Between Japan and EU, we have had theworkshop with Communications Networks,
Content and Technology office every year since
1994. At the same time we exchange ouropinions for making the collaborative researchplan through teleconference. In this paper, we
will report the trend and results especiallyabout three fields of “probe data”, “evaluationtools and methods” and “internationalstandard”, which are agreed to be examined
before anything in the collaborative research
between Japan and US.
2. Trend and result of research“Probe data” : through Japan-US task force
meeting, we discussed the comparison of probe
systems and probe data items between Japanand US and the application candidates enabledby probe data, and put the mid-term report ofcollaborative research in October, 2012. The
summary of the mid-term report was presented
and the fact sheets were distributed at ITS
World Congress Vienna 2012. Hereafter, wewill rank the application candidates, define theservices of selected applications and arrange
the issues in realizing the system. Then weplan to pull the final report together by ITS
World Congress Tokyo 2013.
“Evaluation tools and methods” : in October,
2012, we agreed to the collaborative researchplan where we conduct the comparison andanalysis of evaluation indicators andmeasurement methods in experiments orsimulation cases on cooperative systems of bothsides (Japan and US), the preparation of thedefinitions of terms, the classification andsystematization of evaluation indicators andmeasurement methods, and the arrangementof issues and lessons learned from the

List The Application Candidates Enabled byProbe Data
Application
Estimate traffic managemanet measures
1(e.g., travel time, speed, delay)
2 Identify bottlenack locations
3 Identify accident‐prone locations
4 Identify road closures
5 Detect stopped vehicles or obstacles on the roads
6 Identify duration of congestion
7 Determine pavement traction conditions
8 Identify HazMat vehicles
9 Incident management/Emergency response
10 Route guidance
11 Traveler information
12 Intelligent signal systems
13 Freight operations
14 Transit operations
15 Intelligent network (freeway/arterial) flow optimization
16 Eco‐Signal Operations
17 Eco‐Lanes
18 Dynamic Low Emissions Zone
19 Road and infrastructure deterioration diagnosis

measurement of evaluation indicators, etc. We
plan to put the mid-term report of thiscollaborative research by ITS World Congress
Tokyo 2013.
“International Standard” : as an observer, wekeep on attending “standardization working
group” of “technical task force” onstandardization of cooperative ITS, one of thecooperation fields between EU and US
governments. Thus we collect information andoffer
ourknowledge
about“securitymanagement” and “communications protocol.”3. Development hereafter
Based on the result of the research so far, wewill conduct the collaborative research bytrilateral cooperation of Japan, US and EUhereafter.
