Abstract
A mobile traffic controller to aid pedestrians includes a wireless transmitter and receiver that are configured to communicate with a traffic signal or a traffic control system. In response to a user request, the transmitter sends a traffic control request to a traffic signal or a traffic system controller. The request is acknowledged, and when appropriate, the mobile traffic controller receives a message indicating that a crossing is authorized. The mobile controller can include a vibro-tactile or audio output device for communication with the user. In addition, position and orientation systems can be included so that the user can be directed along a preferred path or alerted that a predetermined or legally established passage zone has been exited or is about to be exited.
