IamA traffic engineer, AMA!
I am a licensed professional civil engineer who specializes in traffic engineering, illumination design, and ITS. I've also done a good bit of land development engineering. So ask me some questions if you want to. I know Chris Pratt is hogging all the spotlight right now, but if you can tear yourselves away from him for a minute to focus on
ramparttraffic engineering maybe you'll learn something about the fascinating world of traffic engineering, illumination, ITS, and some land development engineering.
Edit: here's some proof: my Texas engineer pocket card.
Another edit: I think I've answered all the questions that are currently up, and I'm pretty tired so I think I'll turn in. I'll check back tomorrow morning and answer anything else that comes up.
