Surveys of ITS trends and standardization activities

Vehicle information technology

JARI previously developed the Probe-Car Information System and promoted the development of related international standards. In line with the progress of IT in recent years, JARI has been engaged in surveys, research studies and international standardization activities related to big data, vehicle interface standardization, security and privacy.

Development of Probe-Car Information System and related international standards

JARI launched development work on the Probe-Car Information System around 2000 as a joint project with universities and private-sector companies. The first private-sector service was rolled out in 2003, and the next step was to initiate development work on a centerless probe data system in 2006. In this system, each vehicle functions as a probe data center, with intervehicle communication and road-vehicle communication capabilities used to exchange probe data, which are stored and analyzed to produce useful information such as traffic reports. A feasibility study was conducted in fiscal 2006, and a high-speed mobile intelligent module was developed in a next-generation robot R&D project in 2007-09. Then, a centerless probe using dedicated short-range communication in the 700 MHz band was developed in 2010. Through these centerless probe development projects, the system was developed and its practical utility was verified.

Big data

Remarkable advances have been seen in IT & consumer electronics (CE) in recent years, which are expected to have a significant impact on the automotive industry in the years ahead. Hurdles to bringing software into vehicles have been lowered in one stroke especially by advances in higher speed wireless communication technologies such as mobile phones and Wi-Fi, flat rate plans for sending data via mobile phones, and the explosive diffusion of smartphones.

The existing Probe-Car Information System is mainly designed to provide information to vehicles in the form of traffic reports about congestion and other conditions, based on data collected concerning vehicle positions and traveling speeds. As a result of the lessening of limitations related to data transmission volumes and communication costs, it is now possible to collect a variety of data from vehicles using sensors to detect the surrounding environment. It is expected that such “big data” can be utilized in various useful ways.

Vehicle interface standardization

ISO/TC 204 has been working on developing a vehicle interface (gateway) standard since 2008 to facilitate the collection of various types of data from vehicles. Beginning in 2013, joint meetings have been held with TC22 to discuss certain aspects of the standard.

Meanwhile, the World Wide Web Consortium (W3C), the standards body for Internet and Web technologies, formed the Automotive and Web Platform Business Group in 2013 for the purpose of standardizing Web technologies targeted at automobiles. The first priority taken up for discussion by the group is to standardize a Vehicle Data API specification, which is currently being examined by several organizations. JARI is participating in this activity and is engaged in collecting information from the standpoint of how to utilize vehicle data effectively, while still ensuring the safety of vehicles. JARI plans to make the information available to everyone in due course.


Security technology must be implemented to ensure the safety of vehicles when collecting vehicle data. This is especially necessary today because the recent use of smartphone applications, among other things, has led to increasing situations where vehicles are connected to open networks. This heightens the risk that vehicle safety could be threatened by malware (viruses and other malicious software) attacks, which were not of much concern in the past. In view of this situation, JARI intends to examine what security measures are desirable for vehicles from the standpoint of protection in an open network environment.

International standard for privacy protection

Protection of privacy is also an issue that is as important as security. JARI previously worked together with Keio University and others to develop ISO 24100:2010 that states the basic principles for privacy protection in probe vehicle information systems. At present, JARI is also collaborating with Keio University and other organizations in activities to establish ISO PWI 16461 that stipulates evaluation criteria for visualizing the level of privacy protection in every constituent element of probe vehicle information systems.

Once big data have been collected, the data are analyzed according to each individual purpose, so there is the issue of who has the responsibility for ensuring privacy and at what juncture. This is an issue that needs to be examined in the days ahead.

As a result of increasing opportunities for vehicles to be connected to the external world, the inherent possibilities of such connections should be pursued along with identifying potential issues and investigating effective countermeasures. JARI intends to gather information around the world on related matters and actively participate in international standardization activities, among other efforts.

Research studies concerning ITS industry trends

Since fiscal 1998, the ITS Research Division has continued to survey the technologies and related industry trends supporting ITS. Besides conducting independent in-house studies, JARI also analyzes the results of questionnaires and interviews in cooperation with ITS-related central government ministries and agencies, organizations, companies and others. Issues of concern are identified along with possible directions to be taken in future work, with the aim of eliciting views and ideas from a broad spectrum of related persons. JARI’s efforts to present the latest trends as well as extensive coverage of ITS in general and frank proposals have been well received, and this information is being used in all quarters.

Research studies concerning ITS R&D/standardization

Research studies concerning standardization of ITS in-vehicle systems

Vigorous activities have been undertaken globally in recent years to develop and standardize cooperative systems that use intervehicle communication or road-vehicle communication capabilities to surpass the limitations of individual drivers or onboard sensors. Europe, the U.S. and Japan are engaged in fierce competition to develop and deploy such systems.

JARI surveys R&D projects and other activities pertaining to vehicles and ITS in Europe and the U.S. and analyzes the strategies being pursued there. The results obtained encourage the development of products having high international competitiveness in terms of performance, quality and cost.

Specifically, JARI studies R&D/standardization trends in Europe and the U.S. concerning the information transmitted in cooperative systems and, based on the results, conducts surveys regarding standardization activities in Japan.

Functionality of next-generation in-vehicle system

The development of international standards is a crucial factor in enhancing the international competitiveness of industry and products. ISO/TC 204 is carrying out activities for developing international standards related to ITS. Activities to standardize cooperative systems for providing safe driving support and other forms of driver assistance are moving ahead under the leadership of Europe and the U.S.

JARI serves as the secretariat of ISO/TC 204/WG1 (Architecture and Terminology) and supports the related standardization activities in Japan and abroad. In addition to promoting discussion of Japan’s draft standard proposals, JARI also actively participates in the activities of ISO/TC 204/WG16 (Wide Area Communication) and ISO/TC 204/WG17 (Nomadic Devices), among other working groups.

International standardization activities concerning ITS

Research on uses of IT & CE technologies in ITS


Moves have been under way in recent years to make vehicles safer, more convenient and more comfortable by using IT and consumer electronics (CE) technologies that have become increasingly more sophisticated and widespread, as typified by the Internet. Meanwhile, the protection of personal data and the assurance of security have also become critical issues.

JARI initiated studies early on concerning personal data protection and the assurance of security, making use of the knowledge gained regarding probe vehicle information protection that we have been involved with since fiscal 2002. Those studies were conducted simultaneously with ones concerning possible uses of IT and CE technologies in ITS. JARI is continuing to conduct activities aimed at achieving such uses in collaboration with the efforts being made by the automotive industry.
