Main Roads needs to get out of slow lane

Earlier this year, I wrote about work done around the world to improve the efficiency of roads and reduce congestion.

It included an article about research under way at Carnegie Mellon University in Pittsburgh to build smarter traffic lights – signals that could gather accurate information about traffic conditions and volumes and transfer that information further down the road.
An initial trial of the system resulted in a 40 per cent improvement in traffic flow and a 30 per cent reduction in car stops.
One of its co-ordinators, Dr Stephen Smith, said a growing city like Perth “would benefit from testing and investing in new technologies like those being used in Pittsburgh”.
