无障碍缘石斜坡：坡度、警示带与落差收头

Render a close, detailed study of a correctly built kerb ramp where a Taiwanese sidewalk meets a crossing. Show the ramp running in the direction of travel rather than diagonally into the intersection, aligned squarely with the crosswalk beyond, at a gentle gradient with flared sides that themselves are walkable. Detail a yellow tactile warning field at the bottom of the ramp, set the full width and one paver course back from the kerb edge, with truncated domes clearly modelled. Show the transition to the road as a true flush joint with no lip, and the gutter shaped so water runs past rather than ponding at the base. Keep a level landing at the top of the ramp inside the sidewalk so a wheelchair can stop and wait without rolling. Show a wheelchair user descending the ramp, plus a stroller and an older pedestrian using it. Use a low three-quarter view close to the ramp so the geometry, gradient and tactile detail are all readable, raking afternoon light to reveal the surface plane, and photorealistic concrete, granite and tactile-tile textures.
