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...

Land Use and Transportation Policies for a Sustainable Future with Autonomous Vehicles: Scenario Analysis with Simulations

Liming Wang
Yao-Jan Wu
Even though there are tremendous uncertainties in the timing and evolution path of the Autonomous Vehicles (AV) technology, it may become a likely reality within most MPOs' long-range regional transportation plan horizon of twenty years. Yet a recent survey of largest MPOs in the US indicates only one of them "even mentions driverless, automated, or autonomous vehicles in its most recent RTP" (Guerra, 2016 page 211). One of the uncertainties in assessing the impacts of AV is their direction: ... Read More
