Dear Bin,
Thank you for your reply. I have also drawn the bridges as normal intersections but, being a highway, there are still much less intersections than the main streets of the grid (which have intersections every 100m or less, while the highway has one every 300 or 400m). But it is precisely the lack of intersections that makes the highway a very fast route, attracting more cars than the main streets. But this high vehicle traffic is not shown on the global choice map. Maybe I should draw the extension of the highway beyond the metropolitan area, showing how it connects to the larger territory but I still don't get it because this haighway is mainly used by people who work on the periphery and work at the city center, so the regional connection doesn't seem that important. I attach the NaCh 25k with the highway marked in black (it is only a section but it appears orange and it is one of the main routes, more used than the others that appear red), maybe this will help, thank you,
Mariona Oliver
