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...

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...

Municipal Investment in Off-Road Trails and Changes in Bicycle Commuting in Minneapolis, Minnesota over 10 years: A Longitudinal Repeated Cross-sectional Study

We studied the effect of key development and expansion of an off-road multipurpose trail system in Minneapolis, Minnesota between 2000 and 2007 to understand whether infrastructure investments are associated with increases in commuting by bicycle. We used repeated measures regression on tract-level (N = 116 tracts) data to examine changes in bicycle commuting between 2000 and 2008–2012. We investigated: 1) trail proximity measured as distance from the trail system and 2) trail potential use measured as the proportion of commuting trips to destinations that might traverse the trail system....

Mobility on Demand (MOD) Sandbox Demonstrations Independent Evaluation (IE) – Chicago Transit Authority (CTA) Integrated Fare Systems From Transit Fare to Bike Share Project Evaluation Plan

The Mobility on Demand (MOD) Sandbox Demonstration Program provides a venue through which integrated MOD concepts and solutions – supported through local partnerships – are demonstrated in real-world settings. For each of the 11 MOD Sandbox Demonstration projects, the MOD Sandbox Independent Evaluation includes an analysis of project impacts from performance measures provided by the project partners, as well as an assessment of the business models used. This report constitutes the Evaluation Plan for the Chicago Transit Authority (CTA) Integrated Fare Systems -From Transit Fare to Bike...

Social (In) Equity in Access to Cycling Infrastructure: Cross-sectional associations Between Bike Lanes and Area-Level Sociodemographic Characteristics in 22 large US cities

Cycling advocates have recently argued that low-income and minority communities across the U.S. have disproportionately low access to bike lanes. To date, however, quantitative evidence of disparities in access to bike lanes is limited to a small number of cities. We address this research gap by examining cross-sectional associations between bike lanes and...

Shared mobility-the shared use of a vehicle, motorcycle, scooter, bicycle, or other travel mode-provides users with short-term access to a transportation mode on an as-needed basis. Shared mobility includes various travel modes and service models that meet the diverse needs of users including: carsharing, bikesharing, transportation network companies (TNCs, also known as ridesourcing and ridehailing), and others. The following section, TravelModes, provides U.S. Department of Transportation, American Planning Association, and SAE International definitions of the most common shared mobility...

Shared Micromoblity Policy Toolkit: Docked and Dockless Bike and Scooter Sharing

Susan Shaheen
Cohen, Adam
2019

Shared Micromobility – the shared use of a bicycle, scooter, or other low-speed mode – is an innovative transportation strategy that enables users to have short-term access to a mode of transportation on an as-needed basis. Shared micromobility includes various service models and transportation modes that meet the diverse needs of travelers, such as station-based bikesharing (a bicycle picked-up from and returned to any station or kiosk) and dockless bikesharing and scooter sharing (a bicycle or scooter picked up and returned to any location). Early documented impacts of shared...

Mobility on Demand: Evolving and Growing Shared Mobility in the Suburbs of Northern Virginia

For as long as there have been cities, there have been suburbs. 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. Shared mobility can enhance access and reduce social exclusion in lower-density environments and provide transportation options to carless and public transit-dependent households, particularly in areas without high-quality, fixed-route public transportation service. This chapter discusses the design and evolution of...
