Abstract
The change of the status of a traffic light at a crosswalk is controlled based on an impaired individual's location with respect to the crosswalk. An appropriate alert indicating the status of the traffic light is determined based at least on the location of the impaired individual. The type of impairment may also be used in determining the appropriate alert. The appropriate alert is generated to inform the impaired individual of the status of the traffic light.
Claims20
A traffic light controller for controlling change of a status of a traffic light at a crosswalk, comprising:
- a transceiver for receiving at least one signal indicating a location of an impaired individual with respect to the crosswalk;
- and
- a processor for controlling change of the status of the traffic light based on the signal and determining an appropriate alert indicating the status of the traffic light based at least on the location of the impaired individual with respect to the crosswalk, wherein the transceiver transmits a signal indicating the appropriate alert.
A wireless device for communicating with a traffic light controller at a crosswalk, comprising:
- a transmitter for transmitting at least one signal indicating a location of an impaired individual with respect to the crosswalk to the traffic light controller, wherein the transmitted signal is used to control a change of a status of the traffic light based on the location of the impaired individual;
- a receiver for receiving a signal indicating an appropriate alert based on the location of the impaired individual with respect to the crosswalk;
- and
- a processor for generating the appropriate alert based on the received signal.
A method for controlling change of a traffic light at a crosswalk, comprising:
- receiving at least one signal indicating a location of an impaired individual with respect to the crosswalk;
- controlling, via a processor, a status of a change of the traffic light based at least one the received signal;
- determining an appropriate alert indicating the status of the traffic light based on at least on the location of the impaired individual with respect to the crosswalk;
- and
- transmitting a signal indicating the appropriate alert based at least on the location of the impaired individual with respect to the crosswalk.
