And to be clear, I'm not advocating against apps altogether. Just that the way they're implemented seem to ignore any urban designing. There's no real weighting to roads meant to carry through-traffic. Sometime it feels like it's simple floodfill pathfinding.
I think you're right. AFAIK Google tracks the real-time position of every android device with GPS and location services turned on and uses that to evaluate traffic, then route people around traffic congestion. The algo is essentially trying to work around the appalling failures of "Just one more lane bro i promise just one more lane!" by utilizing all available streets to get from A to B. It is subverting urban design, but in the US at least urban design is terrible and actively counter-productive, consistently making traffic worse in many cases. This does cause problems - Lots of traffic through neighborhoods and increased wear on roads that were never intended to support serious traffic. But it's a reflection of the system trying to find a workable route through the terrible design of urban America.
i feel like Google Maps is pretty freakishly accurate about traffic. I'll map the route from my moms house just to make sure i'm not getting screwed. For public transit nothing is close to Google.
I find google pretty bad for finding new public transit routes even though it's decent at time estimates.
A lot of the time it takes me to less-connected stops that are slightly closer, even though an extra 2 minute walk is worth it to go to the stop that has more busses or trains flowing through it.
I always have to look at which stops are near me, and the routes near me to make a decision as to where to go
I think it optimizes for time and fuel costs, which works most of the time. In my area it almost always takes you along through roads (though it's also kind of e-z mode here). Very annoyingly though the edge cases end up with people driving way too fast by elementary schools.
Fair.
