Evaluating Public Transit Modal Shift Dynamics In Response to Bikesharing: A Tale of Two U.S. Cities

Elliot Martin, PhD
Susan Shaheen, PhD
2014

Public bikesharing—the shared use of a bicycle fleet—has recently emerged in major North American cities. Bikesharing has been found to decrease driving and increase bicycling. But shifts in public transit have been mixed. The authors evaluate survey data from two U.S. cities to explore who is shifting toward and away from public transit as a result of bikesharing. The authors explore this question by mapping geocoded home and work locations of respondents within Washington DC and Minneapolis. Respondents were mapped by their modal shift toward or away from bus and rail transit. The...

3rd Annual Shared Micromobility State of the Industry Report

North American Bikeshare & Scootershare Association
2022

NABSA is pleased to present our third annual Shared Micromobility State of the Industry Report. In 2021, the industry continued to respond to the COVID-19 pandemic with shared micromobility filling critical gaps in essential mobility. The industry continued to rebound and demonstrate tremendous resilience, with the number of systems growing past pre-pandemic levels. This report tracks that progress and the trends that are emerging in the industry.

To inform this report, we have collected data across a wide variety of topics, including ridership metrics, user profiles, employment,...

Shared Micromobility: Policy, Practices, and Emerging Futures

Susan Shaheen, Adam Cohen, Jacquelyn Broader
2022

Shared micromobility services provide travelers with short-term access to shared devices, such as bikes and scooters. Common shared micromobility services include bikesharing and scooter sharing, services that allow these devices to be used for on-demand one-way or roundtrip travel. Advances in internet technology (IT)-based systems led to the growth of shared micromobility since its advent with bikesharing in Europe in the 1960s. However, shared micromobility ridership began to decrease during 2019, in part due to challenges like improper device parking. Generally, shared micromobility...

App-Based, On-Demand Ride Services: Comparing Taxi and Ridesourcing Trips and User Characteristics in San Francisco

2014

The rapid growth of on-demand ride services such as uberX and Lyft, or “ridesourcing,” has prompted debate among policy makers and stakeholders. At present, ridesourcing’s usage and impacts are not well understood. Key questions include: how ridesourcing and traditional taxis compare with respect to trip types, customers, and locations served; whether ridesourcing complements or competes with public transit; and potential impacts on vehicle kilometers traveled. We address these questions using an intercept survey. In spring 2014, 380 complete surveys were collected from three...

Shared Mobility: The Potential of Ride Hailing and Pooling

Susan Shaheen, PhD
2018

Shared mobility with pooled rides is the linchpin for leveraging vehicle automation and electrification to reduce congestion and emissions and to create livable urban communities. The sharing of rides is older than horse-and-buggy travel. Recent innovations make sharing easier, more convenient, and more efficient. Innovative mobility services premised on pooling can lower travel costs, mitigate congestion, and reduce greenhouse gas emissions. They also offer travelers more mobility choices between the traditional bookends of auto ownership and public transit. While the realm of...

Transportation Network Companies Might Be Pulling Riders from Public Transit, but This Could Change

Susan Shaheen, Elliot Martin, Adam Stocker
2023

Transportation Network Companies (TNCs, also known as ridehailing and ridesourcing) have expanded across California over the past decade and changed the way people travel. Using a smartphone, travelers can quickly summon a vehicle from almost anywhere and know what the estimated wait time, travel time, and cost will be before stepping into the vehicle. While TNCs are clearly addressing an unmet need for travelers, their growing popularity has raised a number of policy questions, including if TNCs are shifting people away from public transit and other travel modes (e.g., carshare,...

Impacts of Transportation Network Companies on Vehicle Miles Traveled, Greenhouse Gas Emissions, and Travel Behavior Analysis from the Washington D.C., Los Angeles, and San Francisco Markets

2021

Transportation Network Companies (TNCs) like Lyft, Uber, and their global counterparts have expanded around the world over the past decade and have changed the way that people travel around cities and regions. The individual mobility benefits provided by TNCs have been clear. Passengers can summon a vehicle quickly via smartphone from almost anywhere to take them almost anywhere, with advance communication on estimated wait time, travel time, and cost. TNCs may also provide users with added mobility benefits, especially for those living in areas where public transit service is...

Just A Better Taxi? A Survey-Based Comparison of Taxis, Transit, and Ridesourcing Services in San Francisco

2016

In this study, we present exploratory evidence of how “ridesourcing” services (app-based, on-demand ride services like Uber and Lyft) are used in San Francisco. We explore who uses ridesourcing and for what reasons, how the ridesourcing market compares to that of traditional taxis, and how ridesourcing impacts the use of public transit and overall vehicle travel. In spring 2014, 380 completed intercept surveys were collected from three ridesourcing “hot spots” in San Francisco. We compare survey results with matched-pair taxi trip data and results of a previous taxi user survey. We also...
