I wonder if current navigation apps are smart enough to only propose a new route to a portion of the total number of drivers in that location. Ultimately, the

  At the very least, the estimated time for given routes would update dynamically, as a proposed alternative route became less efficient.

  Have you noticed how good the time estimates have gotten? Clearly they're streering other traffic out of or into the way to keep it even.

    I started noticing this very abruptly - that Google no longer redirects me from congested roadways to low-traffic parallel roads. Now, as soon as I take the exit to a less congested road, my estimated drive time might drop by 5-10 minutes, so clearly Google knows that it isn't sending me down the optimal route. I don't think this used to be the case.

      Interesting - I noticed recently, for the first time, that when I modified a 'fastest' proposed route using local knowledge, I found the predicted time dropped, and that has happened several time since. This may be the result of better predictive modeling, and particularly in recognizing that dumping a lot of traffic into a low-capacity route is pointless. It is probably also a political response to the fact that residential areas don't like having a lot of traffic routed through them, and are pressing for the power to regulate it. Better predictions could also explain toast0's observations even when global optimization is not being attempted.
