I wrote this week about my new Android app, which checks for road traffic problems affecting UK routes. I mentioned that it wasn’t ready for release yet, because there are a few admin issues that I need to sort.
One of the problems is in how I get the routing data.
The app relies on comparing the locations of traffic problems with the user’s route.
Getting the location of traffic problems isn’t too hard as there are feeds from the Highways Agency and the BBC that offer that.
But getting a detailed description of a route between two places, in a format that I can use to compare against the traffic problems, proved harder.
