公共自行车近期文献综述

提供公共自行车服务的城市数量快速发展,从20世纪90年代末屈指可数发展到如今超过800个。通过综述近期公共自行车文献,总结公共自行车研究领域的若干议题。便捷性是出行者使用公共自行车的主要动机。省钱是促使低收入群体使用的原因,与停放站间距离是预测会员数量的重要指标。在一些国家,只有不到半数会员每月使用率少于一次。男性使用率高于女性,但性别失衡情况并未如私人自行车那样显著(至少在自行车使用率低的国家)。年会员最普遍的出行目的是通勤。与私人自行车使用者相比,公共自行车使用者不常佩戴头盔,但在法律强制佩戴头盔的国家,其使用水平则受到影响。公共自行车使用者相比私人自行车使用者不易受伤。未来发展方向包括电动自行车集成、GPS全球定位系统、无停放站系统和改进的公共交通一体化。指出应开展更多研究量化公共自行车在出行方式选择、尾气排放、拥堵和健康方面的影响。

Bikeshare:A Review of Recent Literature

The number of cities offering bikeshare has increased rapidly, from just a handful in the late 1990s to over 800 currently. This paper provides a review of recent bikeshare literature. Several themes have begun to emerge from studies examining bikeshare. Convenience is the major motivator for bikeshare use. Financial savings has been found to motivate those on a low income and the distance one lives from a docking station is an important predictor for bikeshare membership. In a range of countries, it has been found that just under 50%of bikeshare members use the system less than once a month. Men use bikeshare more than women, but the imbalance is not as dramatic as private bike riding (at least in low cycling coun-tries). Commuting is the most common trip purpose for annual members. Users are less likely than private cyclists to wear helmets, but in countries with mandatory helmet legislation, usage levels have suffered. Bikeshare users appear less likely to be injured than private bike riders. Future directions include integra-tion with ebikes, GPS (global positioning system), dockless systems and improved public transport integra-tion. Greater research is required to quantify the impacts of bikeshare, in terms of mode choice, emissions, congestion and health.
