While I can't be sure, I believe that my TomTom Go 730 gives left turns a higher penalty than right turns when calculating a route.
I've seen it pick different roads to go A->B than to go B->A where the only reason I could discern for the difference was minimizing the number of left turns.

- Splines 15y agoNot to discount your possibility, but interestingly enough it's possible there are bugs in the mapping data. See http://testoptimal.com/ref/starwest-2006-mbt-tutorial.pdf http://testoptimal.com/ref/starwest-2006-mbt-tutorial.pdf, page 99 for a neat example. It's sort of ironic, I remember reading a much more in-depth paper from Harry about this specific work, but I can't find it. :-/
- LargeWu 15y agoIt might be minimizing driving time, which would in fact give preference to right turns over left, since you often have to wait for left turns.
- roguecoder 15y agoI remember seeing a paper that suggested outlawing all left turns except onto cul de secs or where at least one road is one way would shorten driving times for everyone. Every time I get stuck behind a huge long line of jerks trying to turn left I think of that and seethe.
