Statistical Inference for Multimodal Travel Time Reliability

Avinash Unnikrishnan
Miguel Figliozzi , Subhash Kochar
Travel time reliability is a key metric of interest to practitioners and researchers. There are several metrics available for travel time reliability - buffer index, planning index, probability of travel time being higher than a specific value, etc. ... Read More

Research Roadmap for the AASHTO Council on Active Transportation (NCHRP 20-123(02))

Jennifer Dill
Chris Monsere , Nathan McNeil
The objective of this project is to develop a research roadmap that can be used by the AASHTO Council on Active Transportation to focus its efforts to foster, support, monitor, disseminate, and implement research on active transportation. The roadmap ... Read More

NSF Collaborative Research: RAPID: Maintain Mobility and Reduce Infection Through a Resilient Transit and Micromobility System

John MacArthur
The COVID-19 pandemic has caused unprecedented disruptions to health, the economy, and transportation systems in cities. The key strategy to combat growth in the infection rate is through "social distancing," maintaining physical separation from othe ... Read More

Exploring Data Fusion Techniques to Derive Bicycle Volumes on a Network

Sirisha Kothuri
Joseph Broach , Nathan McNeil , Kate Hyun , Stephen Mattingly
Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized tr ... Read More

New Mobility For All: Can Targeted Information And Incentives Help Underserved Communities Realize The Potential Of Emerging Mobility Options?

Nathan McNeil
John MacArthur
Technology enabled new mobility options such as ride-hailing (e.g. Uber, Lyft), car-sharing (e.g. ReachNow, Car2Go and Zipcar), and micro-mobility (e.g. bike and scooter sharing), along with services such as ride matching, online/mobile travel inform ... Read More

National Scan of Bike Share Equity Programs

John MacArthur
Nathan McNeil , Joseph Broach
As bike share systems around the United States have grown in number and size in recent years, there has been an increasing effort to ensure that those systems are accessible to all residents, particularly those who have the fewest resources or have b ... Read More

Data-Driven Mobility Strategies for Multi-Modal Transportation

Yao-Jan Wu
Xianfeng Yang , Sirisha Kothuri
By using various modes (e.g., walking, cycling, automobile, public transit, etc.), multi-modal transportation systems are effective in increasing people’s travel flexibility and reducing congestion. Hence, it is critical to understand how roadway s ... Read More

Incorporating Bicycle Activity and Vehicle Travel Reduction from Bicycle Infrastructure into Strategic Planning Tools

Joseph Broach
Kristina Currans
Planners and modelers at all levels of government have been grappling with the problem of how to better represent bicycling when modeling and forecasting future scenarios. Planners want to know how and to what extent infrastructure projects can incre ... Read More

Novel Approaches to Model Travel Behavior and Sustainability Impacts of E-Bike Use

John MacArthur
Christopher Cherry
Electric bikes (e-bikes) are a new mode of transportation that could substantially improve efficiency in the transportation system if adopted as substitutes for cars. Researchers at University of Tennessee, Knoxville, Portland State University, and ... Read More

Bicycle Detection and Feedback Assessment

Christopher Monsere
David Hurwitz
Bicycling is increasing in the United States -- the number of trips made by bicycle more than doubled from 1.7 billion trips in 2001 to 4 billion in 2009 (National Household Travel Survey, 2009). With the increase in bicycling rates, there is a criti ... Read More

Road User Understanding of Bicycle Signal Faces on Traffic Signals

Christopher Monsere
Sirisha Kothuri
Bicycling is increasing in the United States – the number of trips made by bicycle more than doubled from 1.7 billion trips in 2001 to 4 billion in 2009 (NHTS, 2009). With the increase in bicycling rates, there is a critical need for cycling infras ... Read More

Developing Data, Models, and Tools to Enhance Transportation Equity

Amy Lubitow
Julius McGee , Raoul Liévanos
Data from travel surveys are used to forecast demand, inform transportation investments, and craft urban policies. Because these data are so essential to shaping our transportation system, it is critical that hard-to-reach populations—such as low-i ... Read More
