Using a 4-month long trip data from 2019, this street-segment-level (N=13,367) study deployed negative binomial regression to build trip generation and destination models. The extent of the impact of built and social environment-related attributes varies at different temporal dimensions of e-scooting. Regarding spatial pattern, university areas and areas close to downtown generated substantially higher trips than other Minneapolis areas. In terms of temporal pattern, trips are more diffused at night and morning, and more concentrated in midday and evening. The high percentage of residential, commercial, and institutional land uses, a higher land use mix, high-valued parcels, and more food-related Points of Interest are strongly associated with e-scooter usage. E-scooter is heavily used in areas with more bike-dependent commuter, less car-dependent commuter, and young-aged people. Further, the presence of a sidewalk, bike-share station, bus stop, and transit shelter on a street segment positively affect scooter usage. These findings will assist e-scooter operators and city planners to formulate policies. Further, by strengthening the literature, this study can serve as a foundation for cities new in e-scooter mobility.</p></div>","PeriodicalId":100933,"journal":{"name":"Multimodal Transportation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772586322000375/pdfft?md5=b360d6294a55b40b27aa06a737f7cbc5&pid=1-s2.0-S2772586322000375-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72073623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In comparison, this paper develops models to combine all the cabin capacities, including economy and premium (business/first), and solve the optimization simultaneously.

The connection Cologne-Frankfurt, for instance, is frequently used as the prime example for air-rail mode substitution, where a high-frequent rail service from Cologne Main Station to the integrated air-rail terminal at Frankfurt Airport completely replaced air service between the two cities in the year 2007. In recent years, Lufthansa and Deutsche Bahn have gradually expanded this role model into a whole network product covering 24 cities connected for Frankfurt Airport, advertised as Lufthansa Express Rail. In this study, we analyze the potential benefits of Lufthansa Express Rail for the 24 cities in terms of journey time and journey fare, comparing it to flights departing from the 24 origin cities directly. Our results indicate that the network and schedule together do not lead to obvious advantages for either time-sensitive or price-sensitive passengers, compared to the prime example Cologne-Frankfurt.
