Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention displays the presence of a level crossing or the approach of a train to a car driver or a pedestrian on a level crossing where a railway and a road intersect at a plane. Further, the present invention relates to an improvement of a level crossing display device for preventing a level crossing accident. Conventionally, in order to prevent a level crossing accident, a level crossing display device such as a level crossing sign and a level crossing warning device has been provided on a level crossing road in order to prevent a level crossing accident. For example, a sign called a "cross mark" having a substantially "X" shape, a warning light for notifying the approach of a train by blinking two red lights, or a train direction indicator for notifying the running direction of the train by an arrow light And so on. [0003] These railroad crossing display devices are not regulated by laws and regulations in terms of their layout and the like, but are generally installed in a nation-wide manner by consultation between railway operators and road managers. It was a fact. [0004] However, the degree to which a car driver or the like visually recognizes the railroad crossing display device depends on the scenery such as a building around a railroad crossing, an advertisement signboard, and the road conditions such as a hill and a curved road. It is empirically known that, depending on the location, the visibility of a car driver or the like is improved by changing the arrangement of the level crossing signs. [0005] However, the above-mentioned conventional level crossing signs and display devices are generally appropriately fixed to columnar members erected on the road side of the level crossing, and the arrangement positions of the respective signs are naturally determined. As a result, there is a problem that the degree of freedom of arrangement is small. SUMMARY OF THE INVENTION The present invention has been made to solve the above problem, and an object of the present invention is to provide a railroad crossing display device having a high degree of freedom in arranging railroad crossings. [0007] In order to solve the above-mentioned problems, a railroad crossing display device according to a first aspect of the present invention provides a train driver with information related to a railroad crossing where a road crosses a railway plane.
