IT would be interesting to the US number with non-interstate freeways, but that may be too hard.

Absolutely, with all the massive plans, national as well as European, things will change over the next few years. I might just revisit this issue, but it'll have to wait a day or so. Suddenly, bored turned to busy...

I calculated it all with the newest Rand McNally Road atlas of 2008.

I have it at home (i'm at work right now).

The Netherlands:
5012 km of highways (sounds a bit too much to me, but it's what the CBS tells me?
41 (000 sq. km)
394.3 (inhabitants per sq.km)

5012/41/394.3 = 0.31

5012 km is the number of "rijkswegen" i think. Those aren't all freeways.

1091/446/70 = 0.03

Morocco 2010:

2435/446/70 (wont change that bad in 2 years i think) = 0.078

Anyway,here's Hungary's...
1013km - 93030km2 - 109p/km2 :that makes it 0,09
and if I count the approximate final length,then it will be about 0,29.

First it's 1013, not 1030. Second, it's HUNGARY, not Alaska.

Haven't you guys noticed you're calculating too much here?

Length of motorway network per 1000 sq km ÷ population density = length of motorway network per 1000 inhabitants.

So, Slovenia:

457 km ÷ 2000 (2,000,000 inhabitants) = 0.23

That's 0.23 km per 1000 inhabitants (the same method as the original one). Wouldn't the number be nicer, if we say how many people get on 1 km of motorway? In case of Slovenia that would be 4376 inhabitants per 1 km. And why wouldn't we include Alaska? It's sparsely populated anyway.

in The Netherlands it's 7.087 per km. In the Randstad, it's over 10.000 per km. (one of the highest in the developed world).

The Randstad has about 11.850 inhabitants per kilometer motorway.

so you are calculating the following: (Length_of_mways/Area) / (population/Area)

this formula can be reduced to: [lenght of mways / population]

I think this is a good and simple indicator, but not perfect:


- maybe it would be better to divide the LENGTH with the number of cars
(a country with higher motorisation level - cars/pop - needs more motorway)

- maybe it would be more better to correct this number with the average car usage (km/year)...
(a country with higher average car usage needs more motorway)

and this is not perfec yet, because a low pop-density country can be satisfied with a good primary main road network - it is absolutly enough for its low AADT - however a high pop-density country needs motorways everywhere...


So, I think the most important thing is to have a good quality road network which avoids(bypasses) residental areas.

where traffic is low (AADT<4-5000e) a two lane main road is enough.
higher traffic needs more lanes (and grade separation).

where are you from where that last thing is usual? Many Dutch 2 lane main roads have over 20,000 AADT.

from hungary...

20.000 is an extreme number, these roads should be updated to (alleviated by) motorways...

the 5000 AADT limit is my opinion (and not the hungarian reality :-((

Some Dutch records concerning number of traffic by number of lanes:

traffic lights: Julianaplein Groningen ~112,000
2 lane highway: 25,000? (not sure, there are many overcrowded 2 lane roads)
4 lane non-motorway grade crossings: N44 Den Haag 57,000
2x2 motorway: A15 Sliedrecht: 110,000
2x2 motorway with merging lanes: A28 Zwolle 116,000
2x3 motorway: A20 Rotterdam: 180,000
2x3 motorway with mergin lanes: A4 Badhoevedorp 190,000
2x4 motorway: A27 Utrecht 194.000
2x5 motorway: A12 Utrecht 220.000
busiest: A16 Rotterdam 232,000 4x3 lanes
