Advanced accessible pedestrian control system for the physically disabled
First Claim
1. An apparatus, comprising:
- a traffic signal locator configured to determine an availability of a traffic signal;
a transmitter configured to communicate with at least one traffic controller associated with the available traffic signal so as to provide a pedestrian traffic control request associated with establishment of a pedestrian crossing zone; and
a receiver configured to receive a notification that the pedestrian crossing zone has been established and that a pedestrian associated with the traffic control request has exited the established pedestrian crossing zone.

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.

19. A traffic control unit, comprising:
-
at least one traffic signal interface configured to control at least one traffic signal; a radiofrequency transceiver configured to receive pedestrian requests for traffic signal control; and a processor coupled to the traffic signal interface and the transceiver, and configured to establish a traffic signal condition associated with establishment of a predetermined crossing zone in response to the pedestrian request and produce a request acknowledgement for transmission by the transceiver to the pedestrian, wherein the processor is further configured to produce an alarm signal operative to pedestrian an is outside the predetermined crossing zone established in response to the pedestrian request. - View Dependent Claims (20, 21)

22. A traffic control method, comprising:
-
receiving a request from a pedestrian for activation of at least one traffic control device associated with establishment of a safe transit zone; storing a record associated with at least one safe transit zone associated with the traffic control device, and comparing a pedestrian location with the at least one established safe transit zone; activating at least a first traffic control device in response to the request so as to establish at least one safe transit zone; and notifying a pedestrian that the established safe transit zone has been exited based on a comparison of a current pedestrian location and the established safe transit zone, and providing an additional traffic control device activation signal so as to provide an extended safe transit zone.
