Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an as-needed basis. The term shared mobility includes various forms of carsharing, bikesharing, ridesharing (carpooling and vanpooling), and on-demand ride services. It can also include alternative transit services, such as paratransit, shuttles, and private transit services (called microtransit), which can supplement fixed-route bus and rail services. With diverse options for mobility on the rise, smartphone...

Mobility and the Sharing Economy: Industry Developments and Early Understanding of Impacts

Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an “as-needed” basis. Shared mobility includes various forms of carsharing, bikesharing, ridesharing, on-demand ride services, and microtransit. Additionally, smartphone and mobile “apps” aggregate and optimize these mobility services and are critical to many shared mobility modes. Courier network services connect couriers using their personal vehicles or bicycles with freight and seek to disrupt the existing...

Encouraging walking and cycling as means of transportation may have diverse benefits, such as reduced pollutant emissions and increased physical activity in the population. At the same time, individuals who shift to active travel modes may also experience increased risks of traffic...

Bicycle use for commuting is being encouraged not only to address physical inactivity, but also vehicular congestion, air pollution and climate change. The current study aimed to ascertain the urban environmental correlates and determinants of bicycle use for commuting (bicycle commuting) among the working or studying population in Barcelona, Spain. Adults (n = 769; 52% females) recruited whilst commuting within Barcelona (Spain) responded to a comprehensive telephone survey concerning their travel behaviour. Based upon...

Overview of Shared Mobility

Susan Shaheen
Cohen, Adam
2018

Shared mobility—the shared use of a vehicle, bicycle, or other travel mode—is an innovative transportation strategy that enables users to have short-term access to a transportation mode on an as-needed basis (1). Shared mobility includes various service models and transportation modes that meet diverse traveler needs. Shared mobility can include roundtrip services (vehicle, bicycle, or other travel mode is returned to its origin); one-way station-based services (vehicle, bicycle, or other mode is returned to a different designated station location); and one-way free-floating services (...

Peer-To-Peer (P2P) Carsharing: Understanding Early Markets, Social Dynamics, and Behavioral Impacts

Shared mobility services have now become firmly integrated into urban transportation systems across the globe. Carsharing, bikesharing, ridesourcing or transportation network companies(TNCs), and other systems now offer urban travelers access to transportation services that had long been previously only possible through personal vehicle ownership. Carsharing is arguably the pioneer mode of the sharing economy, given it ushered in a new way of thinking and access to the private automobile in the 20thcentury.Since its North American inception in Montreal in 1994, carsharing has undergone...

Public bicycle-sharing initiatives can act as health enhancement strategies among urban populations. The aim of the study was to determine which attitudes and perceptions of behavioural control toward cycling and a bicycle-sharing system distinguish commuters with a different adherence to bicycle commuting.  Methods: The recruitment process was conducted in 40 random points in Barcelona from 2011 to 2012. Subjects completed a telephone-based questionnaire including 27 attitude and perception statements. Based on their most common one-way commute trip and...

Short-Term Planning and Policy Interventions to Promote Cycling in Urban Centers: Findings from a Commute Mode Choice Analysis in Barcelona, Spain

Cycling for transportation has become an increasingly important component of strategies to address public health, climate change, and air quality concerns in urban centers. Within this context, planners and policy makers would benefit from an improved understanding of available interventions and their relative effectiveness for cycling promotion. We examined predictors of bicycle commuting that are relevant to planning and policy intervention, particularly those amenable to short- and medium-term action. We estimated a travel mode choice model using data from a...

Neighborhood Sociodemographics and Change in Built Infrastructure

While increasing evidence suggests an association between physical infrastructure in neighborhoods and health outcomes, relatively little research examines how neighborhoods change physically over time and how these physical improvements are spatially distributed across populations. This paper describes the change over 25 years (1985–2010) in bicycle lanes, off-road trails, bus transit service and parks, and spatial clusters of changes in these domains relative to neighborhood sociodemographics in four US cities that are diverse in terms of geography, size, and population. Across all...
