Exploring the Use of Crowdsourced Data Sources for Pedestrian Count Estimations

Sirisha Kothuri
Nathan McNeil , Kate Hyun , Stephen Mattingly
Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. For safety analysis, they are ... Read More

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

Joe 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

Integrate Socioeconomic Vulnerability for Resilient Transportation Infrastructure Planning

Liming Wang
John MacArthur , Yu Xiao
This research project develops a novel methodology for assessing transportation network vulnerability and resilience, with a particular focus on incorporating social vulnerability into the analysis. The study addresses a critical gap in existing rese ... Read More

Pedestrian Wayfinding Under Consideration of Visual Impairment, Blindness, and Deafblindness: A Mixed-Method Investigation Into Individual Experiences and Supporting Elements

Martin Swobodzinski
Amy Parker
Navigating an unfamiliar place is uniquely challenging for people with disabilities. People with blindness, deafblindness, visual impairment or low vision, as well as those who use wheelchairs, can travel more independently in urban areas with the ai ... Read More

Pedestrian Behavior Study to Advance Pedestrian Safety in Smart Transportation Systems Using Innovative LIDAR Sensors

Taylor Li
Sirisha Kothuri , Xianfeng (Terry) Yang
Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another ... Read More

Statistical Inference for Multimodal Travel Time Reliability

Avinash Unnikrishnan
Miguel Andres Figliozzi , Subhash Kochar
Travel time reliability – or the consistency and dependability of travel times from day to day, and at different times of day – is a key metric that significantly affects people’s travel behavior. Since businesses rely heavily on transportation ... Read More

Exploring Data Fusion Techniques to Estimate Network-Wide Bicycle Volumes

Sirisha Kothuri
Joe Broach , Nathan McNeil , Kate Hyun , Stephen Mattingly
In order to make sure bicyclists' needs are considered when improving a transportation system, planners and engineers need to know how many people are biking, and where. Traditional bicycle counters can provide data for limited sections of the bi ... Read More

Connected Streetcar Project

Kristin Tufte
Larry Head , John MacArthur
This project will create a foundation for deploying connected vehicle infrastructure and facilitating connected vehicle research for the NITC UTC. Connected Vehicle (CV) technology and the associated data has the potential to help us better understan ... Read More

Data-Driven Mobility Strategies for Multimodal Transportation

Yao-Jan Wu
Xianfeng (Terry) Yang , Sirisha Kothuri
How can we use a variety of data-driven speed management strategies to make transportation safer and more efficient for all modes–whether you’re driving, walking or taking transit? The project was led by Yao Jan Wu, director of the Smart Trans ... Read More

Bi-objective Optimization for Battery Electric Bus Deployment Considering Cost and Environmental Equity

Xiaoyue Cathy Liu
Aaron Golub , Ran Wei
Led by Xiaoyue Cathy Liu of the University of Utah, researchers have created a web-based modeling tool that enables U.S. transit providers to explore the impacts of changing over their systems to battery electric buses, or BEBs. The researchers ran ... Read More

Methodologies to Quantify Transit Performance Metrics at the System-Level

Travis Glick
Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applie ... 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
