Mister Y’s mysteries (part 8): Crossing over
Posted by Yacoob on April 18, 2013
At South African traffic lights*, why does the green light stay on for such a short time for pedestrian crossings? It’s only green for a few seconds before it turns red again – which is usually not enough time for the average person to cross the road. The light then flashes red for quite a while longer – even though cars must still remain stationary (since the light is still red for them).
Is it a cruel joke to encourage people to run across roads? Or did the initial designers just grossly miscalculate the timing?
Is it like this in other countries too?
* In South Africa, we call our traffic lights “robots”. Apparently, that amuses people from other countries.
