Summary: This study examines the spatiotemporal patterns of e-scooter trips in four European cities and finds that riding frequencies and vehicle rotation are low. Tourists are the main users of free-floating e-scooters, riding during the day over longer distances but at lower speeds. The peak hour for e-scooter usage is observed in the afternoon, and downtown, waterfront areas, and availability of soft mobility infrastructure attract users. The usage patterns are relatively predictable, especially for commuting purposes.

Summary: The study found that bike sharing can reduce total social cost, even when the operator maximizes its profit. A more attractive metro service can increase the profit of the bike sharing operator. Coordinated operation between bike sharing and metro systems can further reduce total social cost.

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: This paper investigates the mobility patterns of bike-sharing systems from the perspective of bike mobility, rather than user Origin-Destination (OD) data. By reconstructing bike mobility chains (BMCs) and analyzing their spatiotemporal characteristics, the study identifies locality patterns and disparities in bike mobility activities. The results provide valuable insights for urban bike management and broaden the perspective for OD-based data analysis.

Summary: A method to identify DBsMIC is proposed by improving the enhanced two-step floating catchment area and incorporating Bayes' rule, considering parameters such as time, distance, environmental competition ratio, and POI service power index. An empirical study conducted in Shenzhen verifies the high accuracy of the proposed method. The spatiotemporal behavior pattern of DBsMIC is explored using the kernel density estimation method.

Summary: Despite the benefits of cycling, participation rates in Australia are low due to various barriers. This study aimed to identify the specific barriers and enablers of cycling in Melbourne. The main barriers identified were concerns about riding on roads with motor vehicles, collision risks, bad weather, and motorist aggression. The most popular enablers were physically separated bike lanes and improving physical health.

Summary: This study examines the impact of a protected bike lane installation in Boston on nearby bikeshare ridership. The study found a significant increase in bikeshare activity along the new bike lane, as well as on routes unaffected by the intervention. The causal impact of the protected bike lane on affected routes was estimated to increase bikeshare ridership by 80%.

Summary: With the rise of Internet of Things technology, traditional boundaries between people are disappearing. However, this also means that our smart devices are monitoring our daily lives through data collection, making the definition of privacy more complicated. In the age of digital content, concerns about geoprivacy are constantly changing and context-dependent. Various factors influence people's decisions to disclose their location. Current research focuses on computational efforts to protect geoprivacy, without giving enough attention to the variation of geoprivacy perceptions.

Summary: This research examines early fatalities associated with shared e-scooters and identifies potential risk factors and crash configurations. The study found that most crashes involved motor vehicles, with a portion being hit-and-runs. The majority of accidents occurred at night, and adverse weather conditions were present in a significant portion of cases. Two crash types, motor vehicle striking e-scooter from behind and e-scooter operator losing control, accounted for the majority of fatalities. These findings provide important reference for policymakers, stakeholders, and future researchers.

The results show that higher-income and White populations have better access to bike-share service areas. However, as networks expand into lower-income and more racially diverse areas, some equity gaps have narrowed.
