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.
