JP-A-9-318371

  According to the device described in Patent Document 1, the driver does not notice that the speed limit set for each travel point has changed during the travel, and the vehicle is not allowed to remain over the speed limit. There are cases where the vehicle keeps running, and in such a case, unfortunately an unexpected accident is often caused, but it is effective in preventing the occurrence of such an accident.

The various monitoring points described above are generally referred to as orbis (commonly known as mouse traps), and include a fixed type and a mobile type. The fixed type includes a radar type and a type equipped with a speed measuring machine (measuring camera) and a speed warning plate. There is also a loop coil type measuring sensor equipped with a camera and a loop sensor. As a next-generation type, what is called an “NH system” that determines the vehicle speed from blurring of photographic images when a traveling vehicle is photographed with a digital camera is being studied. The radar type includes a so-called stealth type that emits a radar wave (radar wave) only for an instant. In addition, there is a device that uses a photoelectric tube type or infrared type measurement sensor to measure the time for a vehicle to pass through a certain section to determine the vehicle speed.
In addition, the mobile type includes a radar type enforcement machine mounted on the patrol car roof. Road traffic information refers to information indicating these signals and installation positions.

FIG. 3 is a block diagram of a conventional road traffic information receiving apparatus.
