Ok, thanks a lot.

I have another question. Would it be possible to compute the bordering regions of all regions in Europe ? I would like to know, for each and every region, the names of all its bordering NUTS2 regions. If any people has done this, would you know where I could find such a list ?

I am very grateful for your quick answers. I will try it as soon as I have installed the software, working on many projects at the same time.

I had another question before starting the process. Would it be possible a priori to do the same process for regional borders ? If yes, which are the regional borders implemented into the map ? I am looking for European “NUTS2” regions or anything close to it, which are basically the mainly used regions in general. Also, for those two levels, national and regional borders, would it be possible to decompose the number of road crossings ? Such as to obtain a result like this for the national level : _number of road crossings between France and Germany : xx _between Germany and Poland : yy etc and at the regional level : _number of road crossings between Alsace and NordReihn-Westfallen, and then etc for all the regional borders

I don’t know if you have the answers to all those questions, but one never knows ! I will install the software soon and at least try to compute the general number of road crossings at the European level.

Cheers,
