PODCAST: Traffic engineering's role in safely connecting Arizonans

Where do speed limits come from? How are highways engineered, signed, striped, etc., to maximize safety? 

Welcome to the realm of traffic engineering. To explain these and other aspects of state highways, we're pleased to have State Traffic Engineer Kerry Wilcoxon as this week's On the Road With ADOT guest. 

Spend a few minutes with Kerry and host Doug Nintzel and you'll know more about the traffic engineering along state highways. I hope you'll also take away an appreciation for the role drivers play in ensuring highway safety. When nearly all crashes result from driver decisions such as speeding, aggressive driving, inattention and driving under the influence, there's simply no way to engineer our way out of crashes. As we often tell drivers, the keys to safety are in your hands.
