ABSTRACT OF THE DISCLOSURE A street crossing signal device for blind pedestrians. The device indicates the direction of a pedestrian crosswalk, so that the blind person can orient himself in that direction, and provides a signal to that person when the lights at that crosswalk are actuated to invite pedestrian crossing. The device comprises a rigid hand rail which is secured to a post at the crosswalk, with the hand rail having at least a portion thereof oriented in the direction of the crosswalk. The device further comprises a vibrator means which is secured within the hand rail. The vibrator means when actuated causes the hand rail to vibrate. Also provided are means to mechanically isolate the hand rail from the post so that vibrations from the hand rail are not transmitted to the post. Electric circuit means associated with traffic control lights at the crossing are also provided, so that only when the lights at the crosswalk are in a designation inviting pedestrian crossing, the vibration means is actuated.
