Signals

If you want to know way too much about traffic signals, you’ve come to the right place.

We’re about to go behind the scenes when an interchange signal system goes into “flash mode” – that’s traffic industry lingo for flashing red lights.

Trevor Eltringham enjoys serving the motoring public by, literally, keeping highway lights on and traffic signals running.

PRESCOTT – A new traffic signal along State Route 69 near Cordes Junction will be activated this week after the Arizona Department of Transportation finishes up a project to improve safety at the intersection with Spring Lane.

Those finishing touches require lane restrictions on SR 69 between mileposts 264 and 265 Tuesday, Aug. 17, from 9 a.m. to 4 p.m. Drivers should expect delays of up to 30 minutes.

The new traffic signal is set to be activated by the morning of Friday, Aug. 20.

PHOENIX –  Lake Havasu City residents and visitors will start experiencing a smoother flow of traffic on SR 95. Traffic signal crews with the Arizona Department of Transportation are installing updated traffic management technology on 20 signals along a 13-mile stretch of the highway

PRESCOTT VALLEY – While traffic has increased with growth, the Arizona Department of Transportation is smoothing the journey along State Route 69 through Prescott Valley using the latest in traffic-management technology.

National Stop on Red Week aims to educate drivers about the dangers of red-light running and to reduce the number and severity of crashes.

With more than 6,000 miles of highway to oversee and maintain, ADOT relies on its fleet of trusty vehicles to help get the job done.

ADOT’s efforts to ease some of the stop-and-go traffic on Grand Avenue have been pretty successful so far, but you don’t have to just take our word – we’ve got the results to prove it!

Before we reveal those findings, let’s back things up a bit first …

Nothing seems to slow a commute down like having to stop at one red light after another. That’s why ADOT is working to synchronize some of its signals – a move that can help traffic flow a little more smoothly while reducing the type of stop-and-go traffic that can lead to congestion.

If you drive Valley freeways during rush hour, you’re probably pretty familiar with ramp meters … They’re the two-light signals positioned at most Valley on-ramps that tell motorists when it’s okay to head onto the freeway. Ramp meters have been used in the Phoenix-Metro area for about the past 20 years and maybe you think not much about them has changed … but, actually they’ve recently become much more efficient!
