Innovative Mobility Services & Technologies: A Pathway Towards Transit Flexibility, Convenience, and Choice

Susan Shaheen
2012

The number of senior citizens is expected to double by the year 2020, representing 18% of the nation’s population. After age 75, driving performance begins to decline due to changes in health and medication effects. Indeed, one quarter of seniors over 75 are expected to require alternative transportation services in the future. This chapter examines transit and innovative mobility options to better meet the needs of the growing older population in the near (2011) and more distant (2021) future. Barriers to transit use among older adults include anxiety and confusion about using...

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

Susan Shaheen, PhD and Adam Cohen
2019

This toolkit outlines policies and practices for cities integrating shared micromobility into the built environment. The toolkit is divided into four sections that: 1) define shared micromobility and its impacts, 2) describe users of shared micromobility and market potential, 3) review best practices and case studies for curb space management and related policies, and 4) provide a summary of key findings from the toolkit.

Uber and Lyft have made San Francisco’s traffic much worse, study says

May 8, 2019

Ride-hailing services like Uber and Lyft are so popular in San Francisco that they have become the single biggest factor behind the city’s increasingly snarled traffic, according to a new report.

Researchers analyzed millions of trips and concluded that the services accounted for more than...

Understanding Impacts of Incentives on One-Way Electric Vehicle Carsharing: A Case Study of Car2go in San Diego

April 23, 2019

With carsharing, individuals gain the benefits of private-vehicle use without the costs and responsibilities of ownership. One-way (or point-to-point) carsharing is a form of carsharing that enables members to pick up a vehicle at one location and drop it off at another. Typically, the carsharing operator provides gasoline, parking, and maintenance. Generally, participants pay a fee each time they...

Understanding Evacuee Behavior: A Case Study of Hurricane Irma

Stephen Wong; Susan Shaheen, PhD; Joan Walker, PhD
2018

In September 2017, Hurricane Irma prompted one of the largest evacuations in U.S. history of over six million people. This mass movement of people, particularly in Florida, required considerable amounts of public resources and infrastructure to ensure the safety of all evacuees in both transportation and sheltering. Given the extent of the disaster and the evacuation, Hurricane Irma is an opportunity to add to the growing knowledge of evacuee behavior and the factors that influence a number of complex choices that individuals make before, during, and after a disaster. At the same time,...

Automated Vehicles, On-Demand Mobility and Environmental Impacts

Jeffery Greenblatt

2015

We review the history, current developments, projected future trends and environmental impacts of automated vehicles (AVs) and on-demand mobility, and explore potential synergies. Many automobile manufacturers and Google plan to release AVs between 2017 and 2020, with potential benefits including increased safety, more efficient road use, increased driver productivity and energy savings. Estimates of AV energy use and greenhouse gas (GHG) emissions range from an ~80 % or greater decrease to a threefold increase; however, we argue that net decreases are likely. On-demand mobility services...

The Benefits of Carpooling

Carpooling allows travelers to share a ride to a common destination and can include several forms of sharing a ride, such as casual carpooling and real-time carpooling. Because carpooling reduces the number of automobiles needed by travelers, it is often associated with numerous societal benefitsincluding: 1) reductions in energy consumption and emissions, 2) congestion mitigation, and 3) reduced parking infrastructure demand. In recent years, economic, environmental, and social forces coupled with technological innovations are encouraging shared and pooled services. Shared mobility is...

The Future of Urban Mobility

Implications for Shared Urban Mobility for Latin American Countries

Transportation is arguably experiencing its most transformative revolution since the introduction of the automobile. Concerns over climate change and equity are converging with dramatic technological advances. Although these changes – including shared mobility, automation, and electrification – are rapidly altering the mobility landscape,...

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...

Mobility on Demand (MOD) Sandbox Demonstrations Independent Evaluations (IE)

TSRC and Booz Allen Hamilton are partnering to form the IE team for the MOD Sandbox Demonstrations (Task Order 1). The IE team is working to finalize the Evaluation Plans for each of the eleven (11) projects. So far, four (4) of the reports have been published, which can be found below:
