I recently fielded a request from a new member for a map route that would give her the safest route for a road trip scheduled on the 10th of December. Notwithstanding that I still haven't figured out the algorithm that will get our timetravel app up and running, I actually thought about this for a moment....
It turns out that the folks at
wUnderground.com have a tool that allows anyone to look at the "likely road conditions" for any route in the USA as for a time period not to exceed 10 days in the future. I've played around a bit with this and it's a pretty clever approach. So, I think it deserves a mention in this thread!
