Route 2 takes 10 minutes longer than route 1 due to stoplights and traffic.
Results after two weeks: Taking route 1, I can average 41mpg with little effort. Cost per trip was always over a dollar, though, from $1.03 to $1.21. Taking route 2, my average is closer to 37mpg, but my cost per trip is from $0.91 to $1.03.
I'm surprised that the results so far show me it's better to take the route with more stoplights and traffic to minimize cost. It will be interesting to analyze this more closely with more controlled driving and without winter conditions.

In this case the congested route works but that might not be necessarily true. In this case it works out but you are also going 4 miles farther. Which on a 14 mile trip is quite a bit.
That is why instrumentation is so important. Without it it would be impossible to tell. I shave 2 mpg off my commute by re routing to miss one traffic light. Sometime it counter intuitive and that's where instrumentation is so critical.
Congrats on the findings.
