Freeway management system for Sydney's M4 motorway

In a bid to improve Sydney's roads and congestion, Australia's Federal and New South Wales governments are to jointly fund a project to equip the full length of the state's M4 motorway with technology which will improve traffic flows and ease congestion along this vital part of Sydney's road network. The US$17 million project will provide the M4 with an electronic freeway management system consisting of variable speed limit sign, entry ramp signalling, CCTV, digital traveller information signs, and signs advising drivers of lane and speed restrictions.

Transport minister Anthony Albanese says, "Retrofitting the motorway with this cutting-edge technology would give authorities the tools to better manage traffic flows, respond quickly to accidents, and deliver real time information to motorists so they can plan their journeys and avoid frustrating delays.”

    Situated in San Diego County, California, the growing city of San Marcos has seen its population increase by 53.5 per cent since the turn of the century. Although this dramatic population increase has spurred economic growth bringing new business, homes and opportunities to the city, it has also increased traffic congestion along its central corridor, San Marcos Boulevard. This became the most congested arterial in the city, and, by 2006, the second-most travelled corridor in San Diego County.

    As part of a wider Hertfordshire County Council strategy to ease congestion across the county, the council is installing variable message signs to provide live incident information, managed by a centralised control centre at County Hall. The centre opened in October last year at a cost of around US$600,000 and is operated by eighteen staff, who monitor the county’s road network. If an accident occurs, traffic signals can be adjusted and messages displayed in a bid to redirect traffic ease congestion. Mainte

    John Kendall considers the public’s awareness of the benefits of ITS. While the results of developing ITS technology may be clear to readers of ITS International, there is far less evidence that drivers have any appreciation of what the technology is doing for them. So how aware are drivers of the developments that are designed to make their journeys less congested and safer?

    When Texas A&M Transportation Institute was asked to devise a temporary traveller information system for work zones, it started by asking drivers what they need. Robert Brydia explains the thinking, implementation and results. US Interstate 35 (I-35) runs roughly north–south originating in Laredo, Texas and ends 1,500 miles away in Duluth, Minnesota having passed through Oklahoma, Kansas, Missouri and Iowa. Within Texas the I-35 splits into I-35E and I-35W passing through Dallas and Fort Worth respectiv
