Arizona DOT upgrades camera system

Arizona’s traffic operations centre was built more than twenty years ago; the first traffic camera was installed over Interstate10 in 1990. That’s all changed now thanks to a recent US$2.1 million upgrade of the camera system by Arizona Department of Transportation (ADOT) which replaced cables with fibre optic lines, so the cameras now show fresh images every ten seconds rather than every five minutes.

Arizona’s traffic operations centre was built more than twenty years ago; the first traffic camera was installed over Interstate10 in 1990.

That’s all changed now thanks to a recent US$2.1 million upgrade of the camera system by 6576 Arizona Department of Transportation (ADOT) which replaced cables with fibre optic lines, so the cameras now show fresh images every ten seconds rather than every five minutes. The upgrade has also replaced the 32 video screens in the traffic operations centre, enabling staff to scan up to 160 images simultaneously.

Information from the cameras is used provide drivers with the most accurate travel times on the changeable signs above some freeways and to manage incidents and deploy first responders, Highway Patrol cars or tow trucks.

“Now, the system will help give users a much better, accurate story,” said Darrell Bingham, ADOT’s project manager on the upgrade. “The benefit to drivers will be more information when they need it the most to avoid congestion and make informed decisions during their commute.”

Last year, almost 9.4million visitors went to ADOT’s traffic site at az511.gov to check the cameras - nearly 26,000 visits a day from people who rely on the cameras to plan their trips. Travellers can get up-to-the-minute travel times, road conditions and alerts via the web or by calling the toll-free 511 number. The online service gives the added benefit of live traffic footage.

    Refurbishing old dynamic message signs can save money and increase technical capabilities as David Crawford discovers. Evidence is growing on both sides of the Atlantic of the scope for retrofitting old or technically out-of-date dynamic message signs (DMS) with new electronic equipment, to save on the costs of installing full-scale replacements. In the last four months of 2014, a number of US states progressed programmes that achieved savings of more than US$1.75 million (€1.56million).

As more and more traffic data is necessary to satisfy the needs of traffic management centres and traveller information systems, and as traffic detection technology becomes more ubiquitous, transportation authorities are pressured to find more economical ways of expanding their detection systems. Caltrans District 12 is leading this push by deploying the latest detection system from Case Global

    A survey into the effectiveness of weather-related variable message signs on a trans-mountain highway has some interesting results, as Alexis Bacelar told ITS Europe. A study in the Massif Central region of France evaluating the usefulness of winter weather warning signs has highlighted the effect of variable message signs on driver behaviour. During the winter of 2009-2010, road operator Massif Central Direction Interdépartementale des Routes (MC DIR) started installing bad weather-specific variable messag

    David Crawford welcomes the adoption of European-style ITS technology by the US. The Jane Addams Memorial Tollway in Illinois, US is well on the way towards becoming a ‘smart traffic corridor’, taking full advantage of active traffic management (ATM or ‘managed lanes’) technology that originated in Europe. It is one of the first American toll roads to do so; preliminary work began in 2014 and will continue through to 2016. Jane Addams is one of four toll roads operated by the publicly-owned Illinois State T
