Integrated information devices
Personal pagers, cellular telephones, and other mobile digital communications devices could potentially receive transmitted pedestrian signal messages. The increased use of these devices suggests that there may be other technologies and methods to provide information to pedestrians and for pedestrians to call the WALK interval in the future.
Development is ongoing on an integrated handheld computer type device to provide geographic, GPS, intersection layout and real-time signal information to pedestrians who are blind. Communication of a pedestrian call is also being investigated. However, such technology is in the very early development stages.
