ETC 2.0 service on the Metropolitan Expressway
Operating the ETC 2.0 service made it possible to provide drivers with various services such as assistance to avoid traffic jam and safe driving assistance.
1. Assistance to avoid traffic congestion
Provides a wide range of road traffic information, and the car navigation intelligently selects the route. In addition to providing road traffic information for the entire metropolitan area, it displays simple graphics for short distances and wide ranges, providing easy-to-understand service.
When moving between large cities, it provides wide-area road traffic information (required time to destination, road closures, traffic jams, etc.) from ITS spots before junctions where a path can be selected.
It also provides comparisons of routes to the main landmarks on the Metropolitan Expressway as well as comparisons of ordinary roads.
2. Safe driving assistance
Alerts for hidden traffic jams
It alerts you beforehand at spots prone to traffic accidents, such as blind spots just ahead of a curve where you can suddenly encounter traffic jams.
Alerts for obstacles on the road
Information on obstacles such as fallen objects is provided with ITS spots, and compatible car navigation systems automatically display information as you approach the obstacle.
Provides information with images
Provides road traffic conditions with real-time still images.
3. Internet connection service
Provides Internet connection service for some car navigation systems. You can obtain local tourist information and facility information, as well as access the site on the Internet.
By collecting information (probe information) such as car driving speed using the ETC 2.0 service, we track road traffic conditions in real time. It allows us to provide more accurate road traffic information.
