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.

    A fledgling advanced lane management assist system can take the guesswork out of selecting the right lane on a congested freeway, as its inventor Robert Gordon explains. As drivers we’ve all done it and control room staff see it all the time – motorists on congested freeways switching into what they perceive is a faster lane, only to come to a halt a few moments later and watch vehicles in the other lanes continue to move past. Now, by re-analysing readily available data in an advanced lane management as

    Applications of long range radar technology are demonstrating its effectiveness as a first line of defence for highway managers – adding greater resilience and capability to existing systems. Development efforts are bringing long range millimetric wave radar to the fore as a very useful tool for managers of highway networks. Application of radar for wide area monitoring in traffic management remains in its infancy. But recent projects are demonstrating how it can now serve to enhance detection of incidents

    Intelligent intersection control systems have a growing role to play in making urban traffic more efficient. Robin Meczes reports. The idea of every traffic light turning green as you approach it has long been a dream for many an urban driver – and none more so than those driving heavy goods vehicles (HGVs), which are slow and difficult to bring to a halt and then accelerate back to normal travel speed. But that dream has become a reality for some drivers in a small number of cities around Europe in the las
