Welcome to the Roadscapes Wednesday segment! Each week here on Geek Alabama, Roadscapes Wednesday will feature roads and infrastructure related topics. Geek Alabama Editor / Publisher Nathan Young is often called the “road geek” for a good reason, Nathan loves roads and loves talking about roads!
I’ve been asked constantly about how traffic signals and train crossings work together. Train preemption wiring and programming is the answer! There’s a lot to it, as you’ll see in todays episode.
