A nice little visual sketch.
EXT. A PELICAN CROSSING - DAY
A girl is stood at the side of the road at a pelican crossing. The odd car drives past. She presses the button. After a moment the tone sounds. We see the box above the button where the word "Walk" is illuminated. The lights stay green. The girl begins to walk across the road and is suddenly hit by a bus and knocked out of shot. The tone stops. A few more cars drive past. After a moment the lights turn red and the tone sounds again. A car stops at the crossing. We see the box above the button again where the words "Simon says walk" are illuminated.
