Assisting Vision-Impaired Pedestrians To Cross Streets: An Innovative Acoustic Ranging Approach
This project aims to leverage innovative techniques to develop an intelligent system that assists blind pedestrians to decide when it is safe to cross streets, especially at the uncontrolled crossing locations, where neither traffic lights nor STOP signs are available. While great social resources have been designated to install the Accessible Pedestrian Signals (APS) at intersections to provide guidance instructions to people with visual impairments, it is economically infeasible to equip all intersections/walkways across the nation with such infrastructures.
