Submitter's text: "Google location history since I started OTR truck driving 4 years ago. The dots are places where I stopped for more than an hour or so. I like how they sorta form the interstate highway network, you can pick out the I-10, I-40, etc. #trucking"
Damn, he even made it out to Newfoundland.
While sticking mostly to established Interstate corridors (particularly the 40/44/70 continuum), it's interesting to see what non-Interstate corridors that he tended to use could be interpolated from his data. This is what I've got so far:
(1) CA 99, looks like from Bakersfield to at least Stockton.
(2) US 54, Tucumcari, NM > Wichita, KS. With I-35 following, obviously a OKC-avoiding
shortcut.
(3) Avenue of the Saints (US 61, MSR 27, I-380). Hey, gotta get from StL to MSP
somehow!
(4) US 35, OH/WV. Classic diagonal interregional, avoids a lot of potential
chokepoints.
(5) DE 1/US 13 -- Delmarva cutoff, E. Coast S.O.P.
Would be interesting to get a perspective about driving these corridors vis-Ã -vis an all-Interstate set of routes (if that would be feasible). Likely no practical difference on US 35 save the gaps in WV; same with CA 99 and AOS (except slogging through Hannibal), but the others feature at-grade local traffic crossing & mixing. Curiously, all these corridors also figure prominently in the various studies showing commercial traffic volumes -- occasionally equaling or outstripping nearby Interstates (when there are such).
But kudos to the data submitter; even with largely anecdotal information, in the aggregate it illustrates the preferences and predilections of a person who's been in the driver's seat for a few years and has developed some sort of personal algorithm regarding routing; the fact that it corresponds at all with larger databases accumulated elsewhere is in itself striking. This is a "planners, take note!" kind of practical information.
