Over the past 5 years, the number of regular cyclists in New York City (NYC) increased by ~ 140,000 to over 800,000 regular riders. Aiming to promote safe cycling, NYC has developed over 1000 miles of planned commuting and recreational bike paths across its five boroughs. Bike lane obstructions pose a safety risk to cyclists but the extent of such obstructions is unknown. The purpose of this cross-sectional study was to document the frequency and rate of obstructions in protected bike lanes throughout Manhattan, NYC. During the fall of 2018, bicycle obstructions were observed in ten zones of Manhattan, NYC. Three kinds of obstructions within the bicycle lanes were coded: object, pedestrian, and vehicle. A total of 233 obstructions in the protected bike lanes were observed in this study. Obstructions per zone ranged from 11 to 39. The most common type of obstruction was objects, which accounted for 53.2% (n = 124) of obstructions and ranged through zones from 2 to 22. People were the second most common obstruction, which accounted for 28.3% (n = 66) of the obstructions, with a range of 1-22. Vehicles accounted for the remaining 18.5% (n = 43) of the obstructions with a range of 1-9 throughout zones. Findings of this study indicate that, even in "protected" lanes, bikers may be forced into traffic or to approach parked cars, increasing the risk of being "doored."
在过去的 5 年中，纽约市（NYC）的常规自行车骑行人数增加了约 14 万，达到了 80 多万名常规骑行者。为了促进安全骑行，NYC 在其五个行政区内开发了超过 1000 英里的规划通勤和休闲自行车道。自行车道障碍物对骑行者构成安全风险，但这种障碍物的程度尚不清楚。本横断面研究的目的是记录整个曼哈顿自行车道内障碍物的频率和发生率。在 2018 年秋季，在纽约市曼哈顿的十个区观察到自行车障碍物。对自行车道内的三种障碍物进行了编码：物体、行人、和车辆。本研究共观察到 233 个受保护自行车道内的障碍物。每个区的障碍物数量从 11 到 39 不等。最常见的障碍物类型是物体，占障碍物的 53.2%（n=124），范围从 2 到 22。其次是行人，占 28.3%（n=66），范围从 1 到 22。车辆占其余的 18.5%（n=43），范围从 1 到 9，遍及各个区域。本研究的结果表明，即使在“受保护”的车道内，骑车人也可能被迫进入交通或靠近停放的汽车，增加被“开门杀”的风险。
