Actually, that article, and some comments from our very own Dave are quite freaky in some respects as I've been thinking about this for some time.
I can comment from 40 years of living in Livingston, knowing the off road infrastructure intimately, and knowing the car routes intimately, that the path/cycle routes are more direct, and more linked than the on road routes.
Livingston is essentially a grid, you have 2 main roads running North to South. One is a Dual Carriageway which links the M8, and A71, the other is a more minor road which links Adambrae with Deans. There are other main roads which bisect the estates East to West.
Within those main roads there is an 'S' shaped minor road network which connects the various streets within the estates. There are no 'rat runs', every residential street ends in a dead end.
The core path network follows the same 'grid' pattern as the main roads. They are in the most part invisible to the road network, as they run through the middle of all estates to the major work, and shopping areas. They are for the most part 3 meters wide and tarmaced. The residential streets are served with more paths (which are all shared use, 2m wide, and a mixture of paved and tarmac). The residential areas are mostly off road, streets with car parks at end.
As I said earlier there are about 2/3 the number of car parking spaces as there are houses. These are not all used. In most cases it would be possible to get from any house in the town to a work area, or main shopping area at least as quickly as you could in a car.
With regard to local shops, and primary schools, in the estates at least it is easier to walk than it is to drive (dead end streets (to cars) as mentioned above).
Most of the primary schools do not have a drop off area. In fact my old primary school had 2 gated entrances no where near roads, and a 'back entrance' which was the teachers car park, and not available to the general public.
In the case of Livingston, I honestly do believe it was built for walking/cycling, and not to travel freely by car.
Of course, the new 'posh' estates (it still troubles me that I live in an 'equivalent' posh estate elsewhere), are car centric, drive straight up to your double garage.
Again, I'm planning a trip to Livingston next week, any volunteers?
