Design Standards of Urban Roads and Accessory Works Article 20
Regulations governing the barrier-free facility designs of urban roads:1. The barrier-free facilities of roads have a continuous design; placement of objects obstructing pedestrian passage in these areas is prohibited.2. Where slopes are required in barrier-free passages, gradient of slope shall not exceed a ratio of 1:12. Clear width of the sloping path shall be at least 0.9 meter.3. Where the entrance and exit areas of overpasses and pedestrian underpasses are not in the same level as the road surface, a warning area shall be constructed to warn pedestrians of elevation change.4. Where the barrier-free passage leads into a crosswalk at the intersection of a road, passage shall be in the same level as the road surface or a slope shall be constructed in the juncture.

市區道路無障礙設施設計規定如下：
一、無障礙通行空間採連續性設計，且不得設置妨礙行人通行之障礙物。
二、無障礙通行空間設置坡道者，坡道斜率不得大於一比十二；坡道淨寬不得小於零點九公尺。
三、人行天橋與人行地下道出入口及路面高低差變化位置，應設置警示帶。
四、無障礙通行空間於交叉路口連接行人穿越道時，應與路面齊平或設置坡道。
