Australia's New South Wales (NSW) government will soon initiate trials for the $600-million (US$404-million) M4 Smart Motorway project.
NSW's Roads and Maritime department has for several months been installing 41 gantries along the motorway to keep drivers updated on traffic conditions and alerts, using data from traffic sensors deployed every 500 meters, and at exit ramps. The gantries are equipped with lane use management signs, which display variable speed limits, lane closures, and merge instructions, as well as estimated travel times and cause for delays. Ramp meters will be installed at certain entry ramps, to control the flow of on-ramp traffic, during times of heavy congestion.
"When the project is complete, these systems will talk to each other and automatically adjust to incidents and congestion without a manual operator intervening," says Minister for Transport and Roads Andrew Constance.
