The Federal Highway’s Administration’s (FHWA’s) Exploratory Advanced Research (EAR) Program began research on "Intelligent Situation Awareness and Navigation Aid for Visually Impaired Persons" to develop an assistive system for blind and severely visually impaired citizens to navigate and travel independently. Phase I of the research explored and developed situation awareness and assistive navigation technologies to provide blind or visually impaired people with obstacle avoidance and intelligent wayfinding capabilities in indoor environments by enabling them to use wearable sensors such as cameras, three-dimensional orientation sensors, and pedometers. In Phase II, the researchers will extend the research to outdoor pedestrian environments to provide blind users with waypoint navigation, path planning, and advanced warning of special events, such as detours and hazards, through interaction with global positioning systems, geographic information systems, and intelligent transportation systems infrastructure.

One of the Principle Investigators, Zhigang Zhu, for an FHWA Exploratory Advanced Research (EAR) Program sponsored-project on "Intelligent Situation Awareness and Navigation Aid for Visually Impaired Persons" was recognized. In May 2013 during the President's awards, The City College of New York presented Professor Zhu with the President’s Award for Excellence.
