Exploring the Use of Crowdsourced Data Sources for Pedestrian Count Estimations

Principal Investigator: Sirisha Kothuri

Co-Investigators: 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

Expanding Transmobilities: An Art-Informed Methodology For Genderdiverse Travel Behavior

Principal Investigator: Nicholas Puczkowskyj

There is a significant gendered travel behavior research gap in the transportation literature. A plethora of transportation literature identifying and contrasting cisgender disparities exists, but more inclusive approaches to genderdiverse identities ... Read More

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

Principal Investigator: Martin Swobodzinski

Co-Investigator: 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

Principal Investigator: Taylor Li

Co-Investigators: 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

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

Principal Investigator: Nathan McNeil

Co-Investigator: John MacArthur

Low-income residents, immigrants, seniors, and people with disabilities – these are people who stand to gain the most from new tools and services that reduce transportation costs and travel time. However, issues of affordability, technology adoptio ... Read More

Evaluation of Portland Shared E-Scooter Pilot Program Goals and Outcomes

Principal Investigator: John MacArthur

Co-Investigator: Jennifer Dill

Shared electric scooters (e-scooters) are fast becoming a mobility option across the U.S. Many cities are permitting their operation, in part, as a way to provide another option to driving private cars. This could reduce private vehicle miles travell ... Read More
