Further, as the vehicle 20 approaches the pedestrian 34, it is also possible to change the color of the illumination light of the recommended areas 67 and 68 or the type of light animation so as to draw more attention to the pedestrian 34. .
  • FIG. 10 is a view showing still another example of the irradiation pattern of the irradiation light by the road surface lighting device 10. As shown in FIG. FIG. 10 shows an example of an irradiation pattern for irradiating the recommended area 69a, the non-recommended area 69b, and the boundary 69c.
  • the road surface lighting device 10 can change the irradiation pattern such as the color of the irradiation light, the intensity of the irradiation light, and the blinking of the irradiation light.
  • the boundary line may be highlighted as the vehicle 20 approaches the pedestrian 34. Highlighting of the border, for example, changing the border into a noticeable color, increasing the brightness of the border, thickening the border, changing the border from no blinking to blinking, border It is conceivable to animate the blinking of the line.
  • Animating is, for example, a method of forming a boundary line by a series of a plurality of points, giving a time difference to blinks of a plurality of points, and making it appear that a light point moves on the boundary line.
  • the irradiation position setting unit 156 sets the irradiation position of the irradiation pattern with respect to the position where the target pedestrian 34 is present. At this time, the figure or character is deformed so as to be easily read from the direction in which the pedestrian 34 is facing and illuminated.
  • the irradiation position is set in consideration of the position of the pedestrian 34 or the unevenness or inclination angle of the road surface.
  • the planned travel route of the vehicle 20 (for example, the route indicated by the broken line in FIG. 5C) that is vehicle information is taken into consideration. It is possible to set a non-recommended area, further set a recommended area, and set a recommended area and a non-recommended area more accurately.
  • the movement path for guiding the pedestrian 34 to the recommended area can be irradiated with an irradiation pattern (for example, an arrow) that is easy to understand, and the anxiety of the pedestrian 34 can be reduced.
  • an irradiation pattern for example, an arrow
  • the road surface lighting device 10 according to the present embodiment is used, as shown in FIGS. 9A and 9B, the time until the vehicle 20 passes can be displayed for the pedestrian 34. Therefore, the pedestrian 34 can be provided with a preparation time for the passage of the vehicle 20, and the anxiety of the pedestrian 34 can be alleviated.
