Even numbered highways will be in north-south direction and odd numbers would in east west direction.2 digit highways are major ones and 3 digit ones will be offshoots. The order of numbering starts from north to south.So NH 13 would be some where in north in the east west direction and and NH 944 will be an offshoot on NH44 which runs in north-south direction,somewhere in south i guess. We need to analyse more on the data to verify if pattern followed is uniform and truely scientific. Of course there are certain mistakes like it never says what is number of the Krishnagiri-Bangalore which forms part of both NS-corridor and golden quad. > It was incorrectly tagged as a state, i corrected it to locality but i > guess it would take time for it to show up in the low zoom tiles.-- > Thanks. So vandals have started appearing. Nice! So we have grown to reach masses or what :) [1] http://www.indiamike.com/india/buses-automobiles-motorcycles-and-bicycles-f117/new-national-highway-numbers-t110066/ -- Regards Srikanth.L Google Profile <http://j.mp/SrikanthL>
