ITS is appreciated as one of the most promising multimedia businesses, and the potential market is estimated about 50 trillion yen (by VERTIS).
*ITS:Intelligent Transport Systems
Nine Development Areas of ITS (Development)
Advances in navigation systems Electronic toll collection systems Assistance for safe driving Optimization of traffic management Increasing efficiency in road management Support for public transport Increasing efficiency in commercial vehicle operations Support for pedestrians Support for emergency vehicle operations ITS User Services
ITS user services are set by allocating users for each of the nine different development fields in accordance with individual users' needs and conditions under which these needs arise. Framework of ITS User Services

ITS Development and Deployment Milestones
ITS Development and Deployment Milestones
Relation Between ITS and Japan's Standard of Living
ITS is an advanced information network system for road traffic indispensable to the national lifestyle. Thus, in accordance with its deployment, Japan's standard of living is expected to improve greatly in all phases of transport safety and amenities. The relation between ITS and the national lifestyle in the 21st century is assumed as described below.
(1) First Phase (around 2000)
"Service Start of Part of Leading Systems Including the Navigation System" -- Beginning of ITS
In this period, which is the initial stage of ITS, traffic information will be distributed via VICS and similar systems which have already begun service. Traffic congestion information and optimum routes will be displayed on the in-vehicle navigation system so that the driver can achieve pleasant travel including travel time reduction. In the last half of the first phase, electronic toll collection will be started so that traffic congestion at the tollgate will begin to be eliminated.
(2) Second Phase (around 2005)
"Start of User Services" -- Traffic System Revolution
In this period of the 21st century, user services of ITS will be introduced gradually, starting a traffic system revolution. Information distributed to the users by ITS will include service information and public transport information about the destination, which will have enhanced content to further improve the user services. For example, when a trip is being planned, a destination that meets the stated needs and requests of the user is retrieved such that the optimum route and transport facilities up to the destination can be easily selected by considering travel time and other important factors.
The number of traffic accidents on the expressways and ordinary roads will be reduced by supporting the driver's safe driving and improving the pedestrian's safety. If a traffic accident occurs, quick notification and proper traffic restrictions will prevent further damage. Quick response of emergency and rescue activities will save the life of a person who would have not survived in the traditional situation.
On the other hand, the fixed-schedule character of public transport organizations will be maintained and information services will be enhanced to greatly improve the convenience of public transportation. An attempt will be made to improve the efficiency of transactions concerning transport operators so that the nation will benefit from reduced logistics costs.
(3) Third Phase (around 2010)
"Advances in ITS and Enhanced Social System" -- Automated Highway Systems- Realization of a Dream
In the third phase, ITS is advanced to a higher level. As well as the spread of infrastructure and in-vehicle equipment, legal and social systems will be enhanced to firmly establish ITS as a social system, so that the effects will be nationwide. With the realization of further advanced functions, automated driving will be started for full-scale service; the inside of the vehicle will be a safer and more pleasant place.
(4) Fourth Phase (after 2010)
"Maturity of ITS" -- Innovation of Social Systems
In the fourth phase, which is the final period of this project, all systems of ITS will already have been deployed. A full-scale advanced information and telecommunications society will be established with the nationwide optic fiber network and innovative social systems.
In this period, the number of automated driving users will have started to increase such that automated driving will be established as a general system. ITS will come to a period of maturity and be accepted by the nation as a basic system pertinent to road and other means of transport. With full-scale ITS deployment, it is expected that the number of deaths caused by traffic accidents will greatly decrease from that of the present in spite of increased traffic volumes and density. All roads including those within cities will have less traffic congestion, enabling pleasant and smooth travel. In addition, a reduction in business traffic will enable harmonization with the roadside environment and the global environment.
