[0012] The ETC system is a system developed mainly for alleviating congestion near a tollgate, which is one of the main causes of congestion on an expressway. This eliminates the need to stop the vehicle and pay the fee, so that traffic congestion at the toll booth is reduced. If traffic congestion is eased, energy saving,
It will also contribute significantly to environmental improvements such as air pollution and noise reduction around the tollgate.

As described above, the automatic toll collection system has various advantages. In Japan, the automatic toll collection service has been provided at the expressway tollgate in the Chiba area and a part of the metropolitan expressway tollgate since the summer of 2000. It will be started.
By the end of 2003, E to 730 toll booths nationwide
TC lanes will be installed.

[0014]

It is expected that the number of toll booths 31 in which ETC lanes 32 are installed will increase in the future, but ETC lanes 32 are now installed in all toll booths. Do not mean. Therefore, even if the toll roads are the same, there are toll booths 31 where the ETC lane 32 is installed and toll booths where the ETC lane 32 is not installed.

[0015] By the way, as described in the section of "Prior Art", the ETC
When the lane 32 is installed, the on-board ETC

However, when the ETC lane 32 is not installed at the tollgate to which the vehicle is going to pass, unlike the case where the ETC lane 32 is installed,
The guidance that the ETC lane 32 is not installed is not provided. Further, in the conventional navigation system, since the ETC lane 32 is not taken into consideration, no information on the presence or absence of the ETC lane 32 is provided. That is, when the ETC lane 32 is not installed at the tollgate to which the vehicle is going to pass from now, neither the ETC on-board unit 11 nor the navigation system provides guidance that the ETC lane 32 is not installed.

Accordingly, if the toll gate to which the vehicle is going to pass is not provided with the ETC lane 32 (that is, if there is only the conventional lane 33), there is no guidance beforehand, so the occupant is informed that there is no guidance. Therefore, it must be inferred that the ETC lane 32 is not installed at the toll booth where the traffic is going to pass.

However, it is uneasy for the occupants to use the no-guidance. In the future, the penetration rate of the tollgate 31 in which the ETC lane 32 is installed will increase, and if the passenger gets accustomed to the ETC system, the traffic will not pass due to the fact that there is no guidance. It may be very difficult to guess that the ETC lane 32 is not installed at the toll booth that is going to be installed.
