German style traffic signals ( the light goes from green to red same as normal but when it changes to green it flashes the orange with the red then switches to green):
Animated Pedestrian crossings with a countdown timer (counts down the time it will stay green and when it will change to green):
At first it would be interesting for locals but eventually i think they would get used to it and one day laugh at the people from Sydney or Melbourne who think its cool and wish their city was like Adelaide... :wank:
