Although electric scooters (e-scooters) are gaining ground rapidly, research on analysing their users' experience lags far behind practice. Level of Service (LOS) is a promising approach to bridge the gap between research and practice via quantifying e-scooter riders' experience. We reviewed the state-of-the-art literature of e-scooters concerning their users' experience and proposed a preliminary framework for developing e-scooter LOS (SLOS). The findings suggest a lack of studies to evaluate SLOS, and e-scooters are rarely considered in the LOS estimation of other transport modes. Considering the impact of e-scooters in both modal substitute and supplement calls for unique SLOS indices in each scenario to reflect their user's experience realistically. Future studies should analyse the interaction of e-scooters with other road users, particularly pedestrians. This study highlights the importance of treating e-scooter as a distinct transport mode and contributes to matching policy and practice to integrate e-scooters into transport planning.

尽管电动滑板车（e-scooters）正在迅速普及，但分析其用户体验的研究远远落后于实践。服务水平 (LOS) 是一种很有前途的方法，通过量化电动滑板车骑手的体验来弥合研究与实践之间的差距。我们回顾了关于电动滑板车用户体验的最新文献，并提出了开发电动滑板车 LOS (SLOS) 的初步框架。研究结果表明缺乏评估 SLOS 的研究，并且在其他交通方式的 LOS 估计中很少考虑电动滑板车。考虑到电动滑板车在替代模式和补充模式中的影响，需要在每个场景中使用独特的 SLOS 指数，以真实地反映用户的体验。未来的研究应该分析电动滑板车与其他道路使用者，特别是行人的互动。本研究强调了将电动滑板车视为一种独特的交通方式的重要性，并有助于将电动滑板车纳入交通规划的匹配政策和实践。
