Does anyone know how to detect the road speed

I. E. If one of our vehicles was driving on a certain road above the speed limit, we would want to know

But no idea where to get this data from Any help appreciated Thanks

  • What part of the world are you in? That will change were you might get the data from. – Nathan W Aug 9 '13 at 5:08
  • It needs to be international, but I guess I could use multiple providers? – Quade Aug 9 '13 at 5:24

This kind of data is very expensive. If you don't have many thousands of dollars/euros to spare (a small European country can cost you 20k € per year), your only chance is OSM. Check this road speed visualization from ITO to get a feeling for what kind of data is available: http://www.itoworld.com/map/124

  • In Finland there is Digiroad it used to cost 300€ might be cheaper now. – simplexio Aug 9 '13 at 8:09

    @simplexio are you sure €300,-- will buy you a license for commercial use? – underdark Aug 9 '13 at 14:50
  • see digiroad.fi/aineisto/en_GB/delivery , "Digiroad customers are only charged extraction costs." and "EUR 200 + VAT / delivery format / delivery" – simplexio Aug 12 '13 at 11:53
  • ITO world doesn't have a solution yet, but they want to do something in future Can i get this data direct from OSM I.e. pass in lat and Long and return a speed limit for this position/rd? – Quade Aug 12 '13 at 13:52
