Abstract: The present invention relates to a spectrum-expanded road electric sign, a road electric sign control system, and a traffic information acquisition device using the same. To this end, the spectrum-expanded road electric sign of the present invention comprises: a housing provided with a substrate therein; a visible LED array including a plurality of visible LEDs repeatedly arranged on a substrate to allow various types of traffic information to be visually recognized by a driver; and an infrared LED array including a plurality of infrared LEDs repeatedly arranged adjacent to the respective visible LEDs. As a result, even in the case where the driver's visibility is not sufficiently guaranteed due to adverse weather conditions, infrared light in the non-visible light range is also emitted, making it possible to capture an infrared video by capturing infrared images.

Abstract: The present invention provides a concrete vacuum tube segment for a hyper-speed transportation system using ultra-high performance concrete (UHPC) and a manufacturing method thereof. A concrete vacuum tube segment for a hyper-speed transportation system can be easily manufactured using UHPC, in which shrinkage and structural cracking do not occur due to mixing a binder and a short fiber to secure airtightness on the basis of a maximum fill theory, and accordingly, shrinkage of the concrete vacuum tube segment can be reduced even in a partial-vacuum state in which the magnitude of drying shrinkage is very small and quick drying occurs; when mixing the UHPC, an antifoaming agent is mixed and a circular vacuum pump is used to remove generated entrapped air to minimize the entrapped air; and a capsule-type crack healing material, which is able to repair fine cracks, is compacted to secure airtightness of the concrete vacuum tube segment.
