Research Highlights

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 aid of effective wayfinding technology. A new report from the National Institute for Transportation and Communities (NITC) explores how to leverage low-cost methods to enable people to more easily move through public, urban indoor and outdoor spaces...

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Andres Figliozzi
Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian interactions, are not well understood. When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable because at high speeds more vehicles can flow per unit of time and roadway section. However, high traffic/vehicles speeds are not desirable for pedestrians who have to cross urban arterials. In parti... Read More
