论文摘要
最近提出了自动骑行的自行车，作为一种新的，更有效的自行车共享系统方法（BSS），但相应的环境影响仍然没有研究。在早期技术阶段进行环境影响评估对于影响系统的设计以及最终的环境影响至关重要。因此，本文旨在评估自动共享自行车的环境影响与当前基于车站和码头的系统相比，在不同的建模假设和模式换档方案下。结果表明，自主权可以减少每位乘客公里的环境影响，从而将目前的基于车站的BSS和码头的BSS降低33.1％和58.0％。灵敏度分析表明，自主共享自行车的环境影响将主要取决于车辆使用率和基础设施的需求。最后，这项研究强调了目标替代更多污染模式的模式的重要性，尤其是随着传统的移动模式脱碳并变得更加有效。
Autonomous bicycles have recently been proposed as a new and more efficient approach to bicycle-sharing systems (BSS), but the corresponding environmental implications remain unresearched. Conducting environmental impact assessments at an early technological stage is critical to influencing the design and, ultimately, environmental impacts of a system. Consequently, this paper aims to assess the environmental impact of autonomous shared bikes compared with current station-based and dockless systems under different sets of modeling hypotheses and mode-shift scenarios. The results indicate that autonomy could reduce the environmental impact per passenger kilometer traveled of current station-based and dockless BSS by 33.1 % and 58.0 %. The sensitivity analysis shows that the environmental impact of autonomous shared bicycles will mainly depend on vehicle usage rates and the need for infrastructure. Finally, this study highlights the importance of targeting the mode replacement from more polluting modes, especially as traditional mobility modes decarbonize and become more efficient.
