A Comparison of Heat Effects on Road Injury Frequency Between Active Travelers and Motorized Transportation Users in Six Tropical and Subtropical Cities in Taiwan

Hsu, CK
Rodriguez, Daniel
2024
Road traffic injuries (RTIs) pose significant public health threats, particularly for vulnerable road users such as pedestrians and cyclists. While recent studies have revealed adverse impacts of heat exposure on RTI frequency among motorized road users, a research gap persists in understanding these impacts on non-motorized road users, especially in tropical regions where their vulnerability can be heightened due to differential thermal exposure, adaptive capacity, and biological sensitivity. In this study, we compared associations between high temperatures and RTIs across four different...

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

Shaheen, Susan
Cohen, Adam
Farrar, Emily
2019

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...

To Pool or Not to Pool? Understanding Opportunities, Challenges, and Equity Considerations to Expanding the Market for Pooling

On-demand mobility services such as bikesharing, scooter sharing, and transportation network companies (TNCs, also known as ridesourcing and ridehailing) are changing the way that people travel by providing dynamic, on-demand mobility that can supplement public transit and personal-vehicle use. Adoption of on-demand mobility has soared across the United States and abroad, driven by the flexibility and affordability that these services offer, particularly in urban areas where population density and land use patterns facilitate a reliable balance of supply and demand. The growth of app-based...

Planning and Accommodating the Micromobility Revolution and Its Impact on Public Health

Quistberg, Alex
Rodriguez, Daniel
2024

Micromobility has grown immensely over the past decade, encompassing both public shared systems and private ownership, and, as Burford et al. have found, a surge in user injuries and deaths has accompanied the growth. Micromobility refers to the use of small vehicles, such as bicycles and scooters, that are either human powered or electric. These vehicles are ideal for short trips—although electric-powered micromobility has expanded the potential distance range.

What Makes the Route More Traveled? Optimizing U.S. Suburban Microtransit for Sustainable Mobility

Pan, Alexandra
Shaheen, Susan
2025

Microtransit services that provide pooled on-demand transportation with dynamic routing have been used in low-density areas since the 1970s, but improvements to routing technology have led to a resurgence of interest in the past decade. Questions remain about the effectiveness of microtransit to serve riders in low-density, car-dependent suburban areas. Better understanding of the factors underlying microtransit ridership can improve usage of these services and shift travelers to more sustainable modes in suburban areas. We compile a database of suburban microtransit programs from 32...

Communities Are Experimenting with Microtransit to Fill Critical Gaps in Public Transit Service – What Have We Learned so Far?

Shaheen, Susan
Cohen, Adam
Wolfe, Brooke
Martin, Elliot
2024

Microtransit is a technology-enabled transit service that typically employs shuttles or vans (Figure 1) to provide on-demand transportation with dynamic routing. While many rides are dispatched and paid via a smartphone, many services also provide a telephone booking option. A few services accept cash payment and street hails (similar to taxis). Variations of microtransit can include fixed schedules and routes and larger or smaller vehicles. Typically, microtransit services are operated by or provided on behalfof a government entity or nonprofit organization, although privately operated...

What Is the Connection? Understanding Shared Micromobility Links to Rail Public Transit Systems in Major California Cities

Shaheen, Susan
Martin, Elliot
Ju, Mengying
2024

As shared micromobility (bikes and scooters) has proliferated throughout urban areas, there has been growing interest in how it facilitates connections with rail transit systems. This study explores the magnitude of interactions between shared micromobility and rail public transit systems using shared micromobility trip data and rail transit schedule data. We evaluate over one million trips from October 2019 to February 2020 in four California cities (San Francisco, Los Angeles, Sacramento, and San Jose) and develop criteria to identify trips connecting to rail transit. These include...

Benchmarking “Smart City” Technology Adoption in California: An Innovative Web Platform for Exploring New Data and Tracking Adoption

Post, Alison, PhD

Hill, Mary
Huang, Amy
Soga, Kenichi, PhD
Zhao, Bingyu, PhD
2021

In recent years, “smart city” technologies have emerged that allow cities, counties, and other agencies to manage their infrastructure assets more effectively, make their services more accessible to the public, and allow citizens to interface with new web-and mobile-based alternative service providers. This project developed an innovative user-friendly web interface for local and state policymakers that tracks and displays information on the adoption of such technologies in California across the policing, transportation, and water and wastewater sectors for a comprehensive set of local...

Best Practices for the Public Management of Electric Scooters

Reinhardt, Karl
Deakin, Elizabeth, SM., J.D.
2020

This research projects evaluates the social, environmental, and safety impacts of shared electric scooters (e-scooters)’ through a literature review, a nationwide scan of state and local laws and regulations, and a case study of Oakland’s experience with e-scooters, including an analysis of the city’s user survey and our own in-depth interviews. E-scooters offer an enjoyable, low-cost travel option, but are used mainly by young, affluent, white males. To improve equity, cities are requiring e-scooter rental companies to serve low-income and minority communities and some further mandate...

Shared Mobility in Low- and High-Income Regions

2022

Although shared and informal transport are not new concepts in low- and middle- income countries (LMICs), a variety of economic, environmental, and social forces are contributing to the growth of shared mobility in LMICs around the world. Shared mobility—the shared use of a vehicle, motorcycle, autorickshaw, minibus, scooter, bicycle, or other travel mode—is an innovative transportation strategy that enables users to have short-term access to a transportation mode. This paper documents key shared mobility and informal transport concepts, terms, and definitions around the world. The paper...
