There's been major work to implement a partial Intelligent Transportation System in Fargo. I'd like to see this continue into the future in partnership with FM MetroCOG and the three main cities.

Yesterday there was an awful two car accident on East bound I-94, which took up all three lanes of traffic right at the beginning of rush hour traffic. It would've been nice to be warned of an accident ahead as I went under several overpasses before getting to it...

9th St. S./Veterans Blvd.
45th St. S.
I-29
25th St. S.
S. University.

That's five places I could've been warned (as well as several thousand other motorists at the time) of the upcoming accident and I could've diverted off to a different road or taken a route through town.

You could also use these systems to dynamically adjust the speed limits on certain roads due to heavy load, or even to inform approach automobiles they are going to fast for the existing conditions (icy roads).

Another thing is have the data being collected in realtime and available publicly so it can be incorporated into web/phone applications to give live traffic conditions.

Another system includes LED lights in the ground for visual indicators of where to stop/not cross over. I've included that video...

Here's a few examples I've found...
