ROAD SURFACE INDICATION STRUCTURE AND ROAD SURFACE INDICATION SYSTEM
PROBLEM TO BE SOLVED: To provide a road surface indication structure and road surface indication system that are capable of improving visibility.SOLUTION: A road surface indication structure comprises: a fluorescent layer 9 that performs fluorescent conversion on light 27 having a first wavelength and emits light 21 having a second wavelength included in a visible region; an upper layer 11 that is provided above the fluorescent layer 9 and transmits the light 27 having the first wavelength; and a lower layer 13 that is provided under the fluorescent layer 9 and reflects the light 27 having the first wavelength and the light 21 having the second wavelength. The upper layer 11's transmission factor for the light 21 having the second wavelength is higher as an incident angle is larger.SELECTED DRAWING: Figure 2
【課題】視認性を向上させることができる路面標示構造及び路面標示システムを提供する。【解決手段】路面標示構造は、第１の波長の光２７を蛍光変換し、可視域に含まれる第２の波長の光２１を発する蛍光層９と、蛍光層９よりも上方に設けられ、第１の波長の光２７を透過させる上方層１１と、蛍光層９よりも下方に設けられ、第１の波長の光２７及び第２の波長の光２１を反射する下方層１３と、を備え、上方層１１は、入射角が大きいほど、第２の波長の光２１に対する透過率が高い。【選択図】図２
