This study provides an evaluation of the impacts of classroom-based adult bicycle education on bicycling activity, confidence and competency self-perceptions while bicycling, knowledge of the bicycling rules of the road, and mode choice in a sample of residents of the San Francisco Bay Area in the US. Changes were measured with self-administered surveys completed before and six weeks after the course intervention. Self-reported data were validated using objective data collected using the Ride Report app. We used multivariable regression analyses to examine changes in self-...

Adult Bicycle Education Classes Increase Confidence, Feelings of Safety, and Knowledge of Bicycling Rules

2019

Adult bicycle education classes are becoming an increasingly popular strategy to improve safety, mitigate congestion, and reach environmental goals. However, there is limited empirical research on the effectiveness of these classes among adults, and there are no studies evaluating the impacts of classroom-based education on this population. To address this gap in knowledge, a study was conducted evaluating the effectiveness of classroom-based adult bicycle education on delivering changes related to bicycling activity, self-perceptions while bicycling, knowledge of the bicycling rules of...

Evaluating Alternative Measures of Bicycling Level of Traffic Stress Using Crowdsourced Route Satisfaction Data

Approaches for evaluating the quality of bicycling have become increasingly important for planning bicycle infrastructure improvements. Mekuria, Furth, and Nixon’s (2012) “Level of Traffic Stress” (LTS) approach, which requires minimal data inputs and produces a simple and intuitive output, has emerged as a widely-used framework for identifying streets that are “low-stress” for cyclists. The LTS framework is based on a hierarchy of characteristics, largely related to traffic speed and roadway layout, that are presumed to cause higher or lower levels of stress. Despite the apparent...

Social (In) Equity in Access to Cycling Infrastructure: Examining the Distribution of Bike Lanes with Respect to Area-Level Sociodemographic Characteristics in 23 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 has been limited to a small number of cities. We addressed this research gap by examining cross-sectional associations between bike lanes and sociodemographic characteristics at the block group level for 22 large U.S. cities (n = 21,843 block groups). Dependent variables included the presence (yes/no), coverage, connectivity, and proximity...

This report provides Mobility on Demand (MOD) planning and implementation practices and tools to support communities. The report discusses different stakeholders in the MOD ecosystem and the role of partnerships in filling spatial, temporal, and other service gaps. Additionally, the report discusses how MOD can be integrated into transportation planning and modeling. The report also discusses shared mobility implementation considerations, such as rights-of-way management, multimodal integration, data sharing, equity, labor impacts, and the role of pilot evaluations. Finally, the report...

Micromobility Evolution and Expansion: Understanding How Docked and Dockless Bikesharing Models Complement and Compete – A Case Study of San Francisco

Shared micromobility – the shared use of bicycles, scooters, or other low-speed modes – is an innovative transportation strategy growing across the United States that includes various service models such as docked, dockless, and e-bike service models. This research focuses on understanding how docked bikesharing and dockless e-bikesharing models complement and compete with respect to user travel behaviors. To inform our analysis, we used two datasets from February 2018 of Ford GoBike (docked) and JUMP (dockless electric) bikesharing trips in San Francisco. We employed three methodological...

Road safety research in low- and middle-income countries is limited, even though ninety percent of global road traffic fatalities are concentrated in these locations. In Colombia, road traffic injuries are the second leading source of mortality by external causes and constitute a significant public health concern in the city of Bogotá. Bogotá is among the top 10 most bike-friendly cities in the world. However, bicyclists are one of the most vulnerable road-users in the city. Therefore, assessing the pattern of mortality and understanding the variables affecting the outcome of bicyclists’...

Urban transportation is an important determinant of health and environmental outcomes, and therefore essential to achieving the United Nation's Sustainable Development Goals. To better understand the health impacts of transportation initiatives, we conducted a systematic review of longitudinal health evaluations involving: a) bus rapid transit (BRT); b) bicycle lanes; c) Open Streets programs; and d) aerial trams/cable cars. We also synthesized systems-based simulation studies of the health-related consequences of walking, bicycling, aerial tram, bus and BRT use. Two reviewers screened 3302...

What’s the ‘Big’ Deal with Shared Micromobility? Evolution, Curb Policy, and Potential Developments in North America

Susan Shaheen
Cohen, Adam
Broader, Jacquelyn
2021

Shared micromobility – or short-term access to shared bikes and scooters – provides a flexible alternative for households living in urban areas, individuals seeking first- and last-mile connections to public transportation, and those without access to a private vehicle trying to reach jobs and essential services. In this paper, the authors discuss the history, growth, and evolution of bike and scooter sharing in North America; summarize the demographics and impacts of shared micromobility; and explore shared micromobility policies and practices for managing devices and operations such as:...

Assessing Public Health Benefits of Replacing Freight Trucks with Cargo Cycles in Last Leg Delivery Trips in Urban Centers

Increased urbanization, population growth, and demand for time-sensitive deliveries means increased freight movement in cities, which contributes to emissions, noise, and safety concerns. One innovative mode gaining widespread attention for urban deliveries is cargo cycles—bicycles adapted for freight delivery. Despite the recognized potential and possible success of transporting at least 25% of freight via cycle, research remains limited. This research investigates the potential of cargo cycle delivery for last mile freight in Oakland, California, with a focus on the West Oakland...
