The findings reveal that remaining driving range plays a critical role, with significant individual variability in its sensitivity, while perceived range anxiety did not significantly influence choices. Recent changes in helmet regulations have shifted preferences towards faster vehicles. Furthermore, dynamic pricing strategies, such as adjusting ride or unlock fees, can incentivize the use of less desirable vehicles with lower battery range or aid in user-based relocation. Nevertheless, low-range vehicles are less likely to be chosen, even with incentives. These insights provide valuable guidance for operators of electric moped sharing system to improve fleet management and optimize user satisfaction through strategic pricing and battery management.</div></div>","PeriodicalId":23277,"journal":{"name":"Transportation Research Part D-transport and Environment","volume":"145 ","pages":"Article 104772"},"PeriodicalIF":7.3,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gelbach’s decomposition indicated that, regardless of bike type, bike infrastructure was the most critical driver of this spatial inequity, with the built environment and socioeconomic/demographic factors also contributing. Specifically, alongside bike-share station dock density, the lack of on-road bicycle lanes in disadvantaged neighborhoods contributed to the inequitable distribution of both bike types.

The results show that while the spatial distribution patterns are similar, accessibility equity is greater with PT with metro, compared to PT without metro or driving. The “relative surplus” and “surplus” types of time accessibility are found in surrounding areas adjacent to the city center, rather than being concentrated in the downtown.
