Physical demonstration of mathematical traffic model
Now, for the first time, researchers from several Japanese universities have recreated this effect by placing 22 vehicles on a 230-metre single-lane circuit. The drivers drove at a steady 30 kilometres per hour, and whilst initially the traffic flowed smoothly, eventually a backwards travelling shock-wave developed which forced some cars to almost stop and others to increase their speed to 40 kilometres per hour to catch the car in front.
