物理环境特性的客观评价(如速度限制、自行车基础设施)沿着青少年的实际自行车路线仍未得到充分研究,尽管它可以提供重要的见解,以了解为什么青少年更喜欢一条骑行路线而不是另一条骑行路线。本研究旨在通过比较青少年自行车手的实际骑行路线和最短的骑行路线之间的物理环境特征差异,从而深入了解确定青少年自行车手的路线选择的物理环境特征。
在根特(法兰德斯市,比利时北部)被指示佩戴全球定位系统设备,以识别自行车旅行。对于所有确定的自行车旅行,计算了可能采取的最短路线。不是最短可能的自行车路线的实际自行车路线被划分为街道段。使用基于Google街景的工具对细分进行了审计,以评估沿实际和最短自行车路线的物理环境特征。
在160次实际骑行中,73.1%与最短的自行车路线没有区别。对于不是最短自行车路线的实际自行车路线,限速30公里/小时,与尽可能短的自行车路线相比,街道一侧几乎没有窗户的建筑物的道路和没有自行车道的道路的出现频率更高。混合土地利用,与商业目的地的道路,主干道,自行车道用白线与交通隔开,与尽可能短的自行车路线相比,小型自行车道和照明覆盖的自行车道在实际自行车路线上的出现频率较低。
结果表明,距离主要决定了青少年骑行的路线。此外,青少年在住宅街道上骑自行车更多(即使没有自行车道),而在繁忙的街道上骑自行车更少,主干道.地方当局应提供无机动交通的捷径,以满足青少年沿最短路线骑自行车的偏好,并避免沿主干道骑自行车。
The objective evaluation of the physical environmental characteristics (e.g. speed limit, cycling infrastructure) along adolescents\' actual cycling routes remains understudied, although it may provide important insights into why adolescents prefer one cycling route over another. The present study aims to gain insight into the physical environmental characteristics determining the route choice of adolescent cyclists by comparing differences in physical environmental characteristics between their actual cycling routes and the shortest possible cycling routes.
Adolescents (n = 204; 46.5% boys; 14.4 ± 1.2 years) recruited at secondary schools in and around Ghent (city in Flanders, northern part of Belgium) were instructed to wear a Global Positioning System device in order to identify cycling trips. For all identified cycling trips, the shortest possible route that could have been taken was calculated. Actual cycling routes that were not the shortest possible cycling routes were divided into street segments. Segments were audited with a Google Street View-based tool to assess physical environmental characteristics along actual and shortest cycling routes.
Out of 160 actual cycling trips, 73.1% did not differ from the shortest possible cycling route. For actual cycling routes that were not the shortest cycling route, a speed limit of 30 km/h, roads having few buildings with windows on the street side and roads without cycle lane were more frequently present compared to the shortest possible cycling routes. A mixed land use, roads with commercial destinations, arterial roads, cycle lanes separated from traffic by white lines, small cycle lanes and cycle lanes covered by lighting were less frequently present along actual cycling routes compared to the shortest possible cycling routes.
Results showed that distance mainly determines the route along which adolescents cycle. In addition, adolescents cycled more along residential streets (even if no cycle lane was present) and less along busy, arterial roads. Local authorities should provide shortcuts free from motorised traffic to meet adolescents\' preference to cycle along the shortest route and to avoid cycling along arterial roads.
