abstract="Article describes a remote-control device which helps to stop all traffic at crosswalks. The hand-held device, when pushed, squeaks to let a blind pedestrian know when to cross. It will work at any intersection that has a traffic signal equipped to receive the signal. After the device is triggered, traffic at all four crosswalks comes to a halt. The device then emits a tone indicating that the intersection is clear for visually-impaired pedestrians to cross both streets of an intersection. When time is nearly up for a safe crossing, the device emits a series of beeps. Currently, the device is in use at one Norfolk, Virginia intersection which houses the special receiving equipment needed to read the remote's transmission.<p />",
