Five Minutes to Home 13 March 2014

Where on the road am I five minutes from home?

I have data. I can check this. (Images follow.)

Algorithmically, I look for the first data point that's within a suitably small distance from home; then I track back five minutes and plot where I was at that moment. Simple!

Obviously the motorway will be faster than the other roads, but it's surprising to me just how inconsistent it is, given that one can usually travel at the maximum legal speed. It may well be that variations in the last mile or so (off the motorway) are making the difference.

It's not as inconsistent as the other, more urban routes, though.

This actually has some use to me. I tend to listen to audiobooks while en route, and I recode them into five-minute chunks since I use various different devices and I don't have an automated way of transferring my progress between them. So when I'm less than five minutes from home, I shouldn't start another chunk.
