| dc.description.abstract | 本研究旨在透過 106 至 112 年度的人行道檢測數據，了解台灣人行環境近年的變化趨勢。研究採用k-mean集群分析法，就人行道淨寬、全路寬及人行道占比(人行道占比)三個面向進行分群與分析。結果發現，每年約有30%左右的抽查道路，其人行道淨寬未達1.5公尺的法定下限，這些路段多集中在全路寬16至20公尺的較窄道路。而在符合寬度標準的道路中，約六成路段的人行道占全路寬比例僅約20%。檢視歷年全路寬分群結果，更可看出當道路越寬，人行道占比反而有下降趨勢。以30%人行道占比為人行道占比標準，106及107年度的整體表現較佳，109年度則最差。但即便在較佳年度，人行道占比達30%以上的比例仍不到兩成。研究建議主管機關應優先改善全路寬20公尺以下路段的人行道寬度，在條件允許下盡可能拓寬人行空間。規劃較寬路段時，則應以人行道占比30%為目標，適度平衡人車需求。對於原本路幅寬大但人行道比例偏低的路段，可評估縮減車道寬度，提升人本導向。未來除了寬度，人行道鋪面平整度、無障礙設施完備性、遮蔭綠化舒適度等，也應納入考量。制定更完善的人本環境指標與配套措施，以全面提升人行空間品質，打造更加友善宜居的城市。 | zh_TW |
| dc.description.abstract | This study aims to understand the recent trends in Taiwan′s pedestrian environment through sidewalk inspection data from 2017 to 2023. The research employs the k-mean clustering analysis method to group and analyze three aspects：sidewalk net width, total road width, and suitability (sidewalk ratio).The results show that approximately 30 % of the surveyed roads have a sidewalk net width below the legal minimum of 1.5 meters each year. These sections are primarily concentrated on narrower roads with a total width of 16 to 20 meters. Among the roads that meet the width standard, about 60 % of the sections have a sidewalk ratio of only around 20 %. Examining the total road width clustering results over the years reveals that as the road becomes wider, the sidewalk ratio tends to decrease.Using a 30 % sidewalk ratio as the suitability standard, the overall performance in 2017 and 2018 was better, while 2020 was the worst. However, even in the better years，the proportion of sidewalks with a ratio above 30 % was still less than 20 %.The study suggests that the authorities should prioritize improving the sidewalk width of road sections with a total width of 20 meters or less and expand the pedestrian space as much as possible when conditions permit. When planning wider sections, a sidewalk ratio of 30% should be targeted to balance the needs of pedestrians and vehicles. For sections with originally wide road widths but low sidewalk ratios, reducing the lane width can be considered to enhance a people-oriented approach.In the future, besides width, factors such as sidewalk pavement evenness, accessibility facilities, and shade and greenery comfort should also be considered. Establishing more comprehensive people-oriented environment indicators and supporting measures is necessary to comprehensively improve the quality of pedestrian spaces and create a more friendly and livable city. | en_US |
