ボラードとガードレール：車両の侵入を防ぎ、歩行者の通行を妨げない

Show the correct detailing of vehicle barriers along a Taiwanese sidewalk, where the goal is to keep cars and scooters off the walking surface without turning the sidewalk into an obstacle course. Render a line of simple cylindrical bollards set on the kerb line at regular spacing wide enough for a wheelchair and a stroller to pass between them comfortably, each bollard finished in a dark tone with a reflective band near the top. Keep the bollards strictly on the kerb line and out of the walking zone, aligned with the light poles and tree pits. At the sidewalk entrance to a school, show a short run of low pedestrian guardrail set back from the kerb so waiting children cannot step directly into the road, with the rail kept low enough to preserve mutual visibility between drivers and small children. Include a dropped kerb with a tactile strip where the crossing occurs, and no barrier blocking it. Eye-level view along the sidewalk, flat daylight, photorealistic metal, paint and paving, honest Taiwanese street context.
