After a two separate incidents of wrong way drivers this week, one resulting in a fatality, drivers might be wondering what’s being done to stop these incidents from happening.

Drive around the city’s freeways and you’ll see the many big bright red signs dotting various freeway exit and entry points - they read "Do Not Enter" or "Wrong Way."

Despite these oversized warnings, wrong way drivers are still a problem on Valley freeways.

So what else is being done to curb the problem?

In a statement, the Arizona Department of Transportation said its designing a wrong-way detection system that would use thermal camera technology to alert wrong-way drivers, law enforcement and other drivers on the road of a wrong-way vehicle.

ADOT said the system would be the first of its kind in the country. A pilot system will be installed sometime this fall.
