Hello, the work is easy:
There is two shape files, the first one is a line geometry indicating roads the second one, is point geometry indicating portal number.
Things to do:
1.- Snap points to lines
2.- Merge attributes from points to lines
3.- Get a new shape file (line geometry, with the information of both)
And the same for 52 regions, the final result will be 52 shape files as indicated in step 3.
