Summary: Shared bikes, shared e-scooters, and public transit are the main public transportation modes in big cities, and their combination can provide a convenient and flexible multi-modal transportation service. However, they play different roles in a multi-modal transportation system. A case study in Austin explores their unique characteristics and spatial complementarity or competition. The results show that public transit has more pronounced commuting characteristics, while shared bikes are more likely to be used for commuting compared to shared e-scooters. Interestingly, there is spatial segregation between where shared bikes complement public transit and where shared e-scooters complement public transit.

Summary: This study conducted a Geographic Weighted Regression to investigate the impact of various factors on e-scooter trip density in Louisville, KY. It found that factors like land use, age distribution, gender distribution, Walk Score, and Park Score influenced the density of e-scooter trips in the Traffic Analysis Zones. The study suggests that using GWR can provide better insights than a global Ordinary Least Squares model, with local goodness of fit ranging from 0.732 to 0.895.

Summary: Dockless e-scooter services can expand mobility options for underserved neighborhoods but may widen access gaps. Compared to docked bikeshare, shared e-scooters have higher overall spatial accessibility but longer idle time. Bikeshare system's equity program is more effective than e-scooter operators' in promoting usage in low-income neighborhoods.

Summary: This study examines the factors influencing the integration of shared e-scooters with public transit, using 35-day trip data from Chicago. The results show that weather conditions, design features, and multimodal network density significantly affect usage. The frequency of transit service has a positive effect on e-scooter-train integration, while the effect on bus and e-scooter integration is not significant. Safety-related variables and demographic characteristics are also found to be important factors. These findings provide valuable insights for urban planners and policymakers to enhance infrastructure, safety, and encourage efficient e-scooter-public transit integration.

Summary: This study examines how factors such as weather, day of the week, holidays, and special events influence the trip frequency of shared e-scooters and bikeshare in Louisville, Kentucky. The results show that rain decreases the usage of both modes, with certain days of the week experiencing higher usage.

Summary: Shared-e-scooters are being introduced in cities worldwide, but there is often a lack of understanding of their characteristics, benefits, and risks. This research examines scooter use in five North American cities and identifies similar demand patterns across the cities. The study also finds that trip characteristics are consistent across the five cities, but change over time within the same city. Additionally, factors such as weather, infrastructure, sociodemographics, land use, and transit accessibility significantly impact scooter demand.

Summary: Shared e-scooters were introduced in urban public spaces to promote a modal shift from cars in short-distance trips and improve sustainability, resilience, and equity in urban transport. However, without integrated planning strategies, this mode of transport can lead to problems such as illegal parking, an increase in head injuries, and a lack of population diversity among users. A case study in Braga, Portugal was conducted to assess the actual and potential users of shared e-scooters, their socioeconomic profiles, and usage patterns. The results showed usage inequalities among genders, ages, and income ranges, highlighting the need for more socially equitable mobility policies.

Summary: The study found that the design of the braking system affects the safe use of e-scooters, with more riders preparing the left hand brake. However, only one third of riders could correctly identify the basic braking system of the shared e-scooter they last used, and high proportions of illegal behavior were reported by riders.

Summary: This study evaluates the impact of shared e-scooters on public transit and driving reduction. Survey results show that shared e-scooters have been used as a mode of transportation to connect with transit and replace car trips. The study also reveals that certain demographics, such as males, non-Whites, and individuals without a college degree, are more likely to use shared e-scooters.

Summary: This paper explores the potential for replacing car trips with e-scooters in Germany and the resulting impact on greenhouse gas emissions. The analysis shows that 13% of daily car trips, equivalent to 2% of car kilometers in Germany, are suitable for substitution. The level of emissions reduction depends on factors such as e-scooter lifetime and the type of vehicle being replaced. The best-case scenario could achieve a daily reduction of approximately 5.8 kt of CO2eq by replacing trips with conventional cars with e-scooter travel, but replacing battery electric cars may lead to increased emissions under certain conditions.

Summary: This study provides a review of literature on modal shifts in the US and other countries, revealing that shared e-scooters may be a good strategy for reducing car dependence in many US cities. However, the extent of integration between shared e-scooters and public transit varies by city, suggesting the need for technology, regulations, and incentives to ensure successful integration.

Summary: This study examines the impact of shared e-scooters on bus ridership in Louisville, Kentucky, prior to the COVID-19 pandemic. The results show that shared e-scooters do not significantly affect local bus ridership, but could potentially complement express bus routes. Further research on express routes is recommended.

Summary: This paper introduces a sequence of models for optimal overnight charging and rebalancing of shared electric scooters. By allowing charging of e-scooters on rebalancing vehicles, the proposed hybrid approach can produce good quality solutions for large-scale instances in a much shorter computation time. The study demonstrates the efficiency and effectiveness of the integrated operations at both local and line-haul levels.

Summary: Bikesharing is an affordable mode of transportation that can potentially reduce car usage in cities. However, it is often used more by affluent populations. Indego, Philadelphia's bikeshare, aimed to promote equity by integrating e-bikes into their system. This study found that the integration of e-bikes successfully increased usage in disadvantaged areas.
