Overview of the Estimated Fiscal 2000 Budget Request for ITS by the Ministry of Construction

(3) Information Highway Construction

Points for Fiscal 2000

About 50% of the sites of neighboring prefectural offices (Note 1) will be connected with information boxes and the like, supporting the construction of a trunk network for interconnection of telecommunications transmission stations, which are concentrated in the sites where prefectural offices are located.
More information will be made public concerning the situation of information box provision and so on, simplifying the procedures for optical fiber installation.

Fiscal 2000 Involvement

1. Provision of optical fibers for highway management

Optical fibers for highway management will be installed and used to transmit data including real time images obtained from management cameras (ITV) (Note 2).

Highway Management Using Optical Fibers

(Trial use on ordinary national highway No. 17 at Mikuni Pass)
Winter management has been challenging for the zone leading to Mikuni Pass on the border between Gunma and Niigata Prefectures, since this zone is steep and mountainous and is a cold area with snow accumulation. Therefore, we installed ITV to monitor the situation of snow accumulation, freezing, etc. on the highway, and used optical fiber connections so that video images can be checked at offices and branch offices. This has made it possible to determine the situation of roadway snow accumulation in real time, allowing the establishment of an operation system with continuous management and so on, and enabling the efficient planning and direction of snow removal and salting work.

2. Provision of Optical Fiber Capacity Space

(1)

To promote the efficient private sector optical fiber installation, in addition to a trunk network between Tokyo and Kyushu, we will connect about 50% of all sites with neighboring prefectural offices.

Information box provision: About 1,600 km

Notes:

Neighboring prefectural offices: Sites where there are offices of prefectural governments in neighboring prefectures connected directly by national highways and the like.
ITV: Industrial Television (Closed Circuit Television). Cameras are installed on roads and so on to allow rapid determination of the situation on roads, in tunnels, and so on. The term can also refer to the equipment used to transmit and display images from those cameras.
This diagram shows those sites of information box installation which have at least a certain length (generally 50 km) of continuous installation.>
