I changed it into "Motorway, Freeway and Expressway can all mean the same!", which is what I orgininally meant.

The British road authorities seems to agree with the Norwegians, check page 3 of this document.
There's just a note to users on page 3.
The tables for capacities in this document, however, are rather converse to the initial claim. They state greater lane capacity for 2 lane road than for 4 lane roads. The difference isn't significant though.

Basic dumb.people meanings in grade schoolers english:

CAR ROAD =
- 2x2 3x2 + lanes
- directional segregation (be it a concrete wall , a 3m wide gap , steel rails , etc)
- large side stoping lanes/hardshoulders
- exits/entrances are not at level
- segregated route such that a pedestrian , an animal or a non motorized veichle is forbiden to enter/circulate
- some may add other "localized" carachteristics such as: tolls , service areas (for fuel , food , hotels, etc) , etc etc etc
- have some bizzar combinations of names such as: auto+route , auto+pista , auto+estrada , motor+way , high+way , something.odd+way , auto/moto+foreighn.language.meaning.road , etc

Priority route =
- anything is permited here ... from CAR ROAD to DIRT ROAD ... usualy just means that is a MAIN ROAD ... with aleatory standards aplied ... wich are different from country to country ...
- call it expresso+way , via+rapida , auto+via , whatever+wherever ...

DIRT ROAD = the rest ... with or without asphalt ...

Changing subjects:

2 lane = 20.000 vehicles
2+2 lane = 65.000 vehicles
3+3 lanes = 100.000 vehicles

or something like that

We would have to upgrade almost all remaining 2x2 motorways if 65.000 is the limit.

I think these are the Dutch top intensities:

2 lane = 30,000 various provincial roads
2x2 lane = 110,000 A15 Sliedrecht, A28 Utrecht
2x3 lane = 180,000 A20 Rotterdam
2x2 through + 2 merging lanes on both sides = 204,000 (A27 Utrecht).

Sorry, I meant page 11, you are right if you think about similar standard single carriageways in Britain, but not dual carriageway (or single direction roads) which I was thinking about:

Single carriageway, two lanes, capacity each direction, hourly capacities:
UAP1, 6.75 m, total: 1320, lane: 1320
UAP1, 7.3 m, total 1590, lane 1590
UAP2, 6.75 m, total: 1260, lane: 1260
UAP2, 7.3 m, total 1470, lane 1470
UAP3, 6.75 m, total: 1110, lane: 1110
UAP3, 7.3 m, total 1300, lane 1110

Single carriageway, 4 lanes, capacity each direction, hourly capacities:
UAP1, 14.6 m, total 3050, lane 1525
UAP2, 14.6 m, total 2100, lane 1050

Dual carriageway, 4 lanes (2+2), capacity each direction, hourly capacities:
UM (motorway), 7.3 m, total: 4000, lane 2000
UAP1, 6.75 m, total: 3350, lane: 1675
UAP1, 7.3 m, total 3600, lane 1800
UAP2, 6.75 m, total: 2950, lane: 1475
UAP2, 7.3 m, total 3200, lane 1600
UAP3, 6.75 m, total: 2300, lane: 1150
UAP3, 7.3 m, total 2600, lane 1300

I.e, all dual carriageway 2+2 urban roads have higher lane capacities than similar standard single carriageway roads according to this British publication (of course, there is no similar standard for motorways). For rural roads I guess the difference is higher, but there safety is still a better argument for building dual carriageways.

In the Netherlands, they use 2200 to 2500 per lane. That's why we widen our roads too late. I heard the Coentunnel (A10 Amsterdam) has 3000 vehicles/hour/lane during rushhours. However, the Coentunnel is jammed for most of the day.

I drove from Abcoude to Utrecht (A2) and on to Germany on the A12. From Abcoude to Driebergen most of the traffic was jammed. I made some pics of it.

A single motorway lane has a capacity of ca. 1600 /hr.
This numbeer can be counted every day on the tidal-flow lane of the A1 Diemen-Muiderberg.

Motorway / highway standards of your country

Hi guys,

Would all of you guys mind sharing the infos about the motorway / highway standards of your countries...? For me, it is important as highways, motorways and expressways are built with certain standards applied by the government of the respective countries. The factors being considered include lane width, design speed limit, access control, and applications.

Let me start first with the Malaysian highway standards...

All highways and expressways in Malaysia are subject to Malaysian Public Works Department (JKR) urban/rural highway standards, ranging from R1/U1 to R6/U6. The application of the standards are as follows:-
  • R6 (high-speed expressway) /U6 (urban expressway) - High-speed motorway-standard toll expressway with full access control (access via grade-separated interchanges only), with the maximum speed limit of 110 km/h. All expressways must be dual-carriageway with at least 4 lanes (2 lanes per direction). All rural expressways must have emergency lanes but some urban expressways do not have emergency lanes, for example Sungai Besi Expressway (Expressway E9). Exclusive for toll expressways administered by Malaysian Highway Authority. Max design speed: 120 km/h (rural); 100 km/h (urban).
  • R5 (main federal/state highway) / U5 (primary urban highway) - partial access control (can be accessed via interchanges, roundabouts or at-grade junctions). Some R5-grade highways may have certain characteristics of a typical R6 expressways (emergency lanes, interchanges, dual-carriageways) but the lane width limited to 3.5 m. Max design speed: 100 km/h (rural); 80 km/h (urban).
  • R4 / U4 - Secondary federal/state/urban road with relatively medium geometric design, partial access control (usually via at-grade junctions, but in some cases the road can also be accessed via interchanges) and lower speed limits. Max design speed: 80 km/h (rural and urban).
  • R3 / U3 - Tertiary federal/state/urban road intended for local traffic only, with partial or no access control. Max design speed: 60 km/h (rural); 50 km/h (urban).
  • R2 / U2 - Roads with the lowest geometry design for a typical 2-way 2-lane road, intended for local traffic only. Max design speed: 50 km/h (rural); 40 km/h (urban).
  • R1 / R1a / U1 / U1a - Single-lane road with very low traffic encounters. Max design speed: 40 km/h (rural and urban).

Lane width:-
  1. R6/U6: 3.6 m
  2. R5/U5: 3.5 m
  3. R4/U4: 3.25 m
  4. R3/U3: 3.0 m
  5. R2/U2: 2.75 m
  6. R1/U1: 5.0 m (whole width)
  7. R1a/U1a: 4.5 m (whole width)


Examples of applications:-

Rural:-
  • R6: North-South Expressway (Expressways E1 and E2)
  • R5: Federal Route 1 (national road from Bukit Kayu Hitam to Johor Bahru)
  • R4: Selangor State Route B33 (Kuala Selangor-Batang Berjuntai)
  • R3: Highland sections of Federal Route 145 (Simpang Pulai-Cameron Highlands-Gua Musang)
  • R2: Entrance road from Federal Route 94 junction to Felda Taib Andak, Kulai, Johor
  • R1: Paved single-lane village roads

Urban:-
  • U6: Ampang-Kuala Lumpur Elevated Expressway (Expressway E12)
  • U5: Kuala Lumpur Middle Ring Road 1 (Jalan Tun Razak, Mahameru Highway, Jalan Damansara, Jalan Istana and Jalan Sungai Besi)
  • U4: Jalan Sultan Ismail, Kuala Lumpur
U3-U1: Cannot think of any!

The Netherlands

SW (Stroomweg) (highest category)
An SW is the highest road category in the Netherlands, and are divided in national stroomwegen, and regional stroomwegen. They are intended to be high speed roads.

National stroomwegen are usually motorways, which have grade-separated intersections, are prohibited for slow or non-motorized traffic and have a speed limit of 100 or 120 km/h. The lane width is usually 3.5 m. They always feature an emergency lane.
Regional stroomwegen are expressways, but there are few expressways which have motorway-standards. They can be 2x2, but often lack a shoulder. The speed limit is 100 km/h or lower. They can also feature only one lane per direction, and do not always feature a median.

GOW (GebiedsOntsluitingsWeg) (main road)
There are 2 categories: in and outside city limits. Outside the city limits, they have a speed limit of 80km/h, and 50 or 70km/h inside city limits. Their lane width is usually 2,75m and can have 2x2 lanes, but with traffic lights or even roundabouts. These roads carry the bulk of the non-motorway traffic.

ETW (ErfToegangsWeg) (secondary or lower road)

These roads are less important roads, and usually cover a rural area with a 60km/h limit, despite how the road layout is (often 60km/h roads are designed at a 80km/h speed limit). Inside city limits, they are in residential area's witha 30km/h speed limit, but often they also include thoroughfares inside neighborhoods which looks like a 50km/h road.

My comments on this system: The idea of classifying roads is good, but often they degrade roads with a 20km/h lower speed limit than the road is designed for. This results in a major amount of speeding and speeding tickets. They are popular spots to install speed camera's, resulting in a huge amount of speeding tickets. Many drivers are frustrated by these low speed limits.

In czech republic we have those cathegories:

example D26,5/120... D means cathegory of road, 26,5 is whole width and 120 means design speed
  • D (dálnice = highways)
    • D 33,5/120 (100,80) - highway with 3+3 lanes, lane width 3,75 , 3,75 and 3,5 m
    • D 27,5/120 (100,80) - highway with 2+2 lanes, lane width 3,75 m
    • old D 26,5/120 (100,80) - no usage now, highway with 2+2 lanes, lane width 3,75 m
  • R (rychlostní silnice = expressway) - lower standarts of curves and gradient than by highways
    • R 33,5/120 (100,80) - expressway with 3+3 lanes, lane width 3,75 , 3,75 and 3,5 m
    • R 27,5/120 (100,80) - expressway with 2+2 lanes, lane width 3,75 m
    • R 25,5/120 (100,80) - expressway with 2+2 lanes, lane width 3,75 m
    • old R 24,5/120 (100,80) and R22,5/-- - expressway with 2+2 lanes, lane width 3,5 m
  • S (ostatní silnice = other roads) - yet divided into first class road, second class and third class
    • S 24,5/100 (80,70) - first class road with 2+2 lanes, lane width 3,5 m
    • S 20,75/90 (80,70) - first class road with 2+2 lanes, lane width 3,25 m
    • S 11,5/90 (80,70) and S 9,5/-- - first class road with 1+1 lanes, lane width 3,5 m
    • S 7,5/-- S6,5/-- and S4/-- (usual design speed 70-30kph) - road with 1+1 lanes, lane width 3,0 to 2,75 m

  • MR, MS, MO, Mok - city roads
    • MR - urban speedway
    • MS - main streets (collecting road)
    • MO - frontage roadway
    • Mok - frontage roadway with shoulder

Croatia

A roads (A1-A11) are full profiled motorways (autoceste). mostly tolled (about 95% of them)

B roads are so called fast roads (brze ceste). they might be same as motorways, but without SOS lanes, or they can be 2 way roads with or without SOS lanes, but with all denivelated intersections. currently there are only B8 and B9 existing (although there are more roads with B standards). tolls are collected at large objects.

D roads (državne ceste) are state roads.

D1-D9 (one digit) are main routes in the country. some of them have collission with motorway routes (for instance D4 doesn't exist anymore, but its route is completely the same as A3 motorway's - that's because D numbers are much older than A numbers)
D20-D64 (two digits) are not representing that important routes as one-digit D roads, but they might be in better cindition than some one-digit D roads.
D100-D524 are third graded state roads. again, not neccessarly in poor condition. also, there are some three-digits D roads in fantastic condition because new built bypasses or connectors get those numbers. D1xx roads are located at the islands. D2xx go to or from border crossings. D4xx go to or from ferry- and air-ports. D3xx and D5xx have no rules.

some of D roads are "blue" roads (reserved only for motorized vehicles) and some are built in really high standards, for instance D28 has 25 km long section which is pure B road (2+2, no SOS lanes, no same-leveled intersections)

ŽC roads (županijske ceste) are county roads. they may lead between 2 counties, but they are going mostly through inhabited places and have no such high standards as D roads. numbers are in rage ŽC1001-ŽC6253 (allways 4 digits)

LC roads (lokalne ceste) are local roads. it is the lowest class of the roads allways out of some importatn routes. range of numbers: LC10001-LC69065

5-digit road numbers? I don't think I have ever seen that before, are these roads signed?

no. i haven't seen them anywhere signed (if you mean at direction signs), it's only at paper. those are really unimportant roads, long up to some 15 km and usually connecting 2 villages. but those 4 digit can be seen at signs

What about this then?



We're a big country, so we need many numbers. They are rarely signed though.

In czech republic we also have 5-digit road number. In third class roads. For example III/15269.

Here I´m posting the whole road system of south-moravian district
http://www.rsd.cz/sdb_intranet/sdb/i...je/kraj_jm.jpg
If you look closely, you can see that first class roads have one or two digits, second class roads have 3 digits and third class roads have 4 or 5 digits.

But I never saw number of third class road on the road sign.

Slovakia

In Slovakia it's similar to Czech republic: D 26,5/120: D - category of road; 26,5 - whole width and 120 - design speed

D - motorways (diaľnice)

D 28/140, 120
D 26,5/140, 120, 100, 80
D 24,5/140, 120, 100, 80

Majority of Slovak motorways is build using D26,5/150, 120, 100 or 80 parameters. (Design speed 150 is not in use anymore).

R - expressways (rýchlostné cesty) - I think no explanations are needed for both motorways and expressways. Maybe only that all those parameters can be modified for 6 lanes just by adding 7 to the width. For example D26,5/120 becomes D33,5/120 when it's six laned.

rarely R 26,5/120, 100, 80
R 24,5/120, 100, 80
R 22,5/120, 100, 80
R 11,5/120, 100, 80

Majority of Slovak expressways is build using R 22,5/120, 100 or 80 parameters.

C - roads (cesty) - Every road is member of some class, we have 3 classes. First class roads have one or two digit numbers, e.g. I/61. Second class roads have three digit numbers, e.g. II/499. Third class roads have four or five digit numbers, e.g. III/06596.


First class roads:
C 22,5/100, 80 and 70
C 11,5/80, 70 and 60
C 9,5/80, 70 and 60;

First class roads connect important national and international destinations, important border crossings and the most important cities.

Second class roads:

C 22,5/100, 80 and 70
C 11,5/80, 70 and 60
C 9,5/80, 70 and 60;
rarely C 7,5/70, 60 and 50

Second class roads connect districts, regions and smaller cities and towns.

Third class roads:
C 11,5/80, 70 and 60
C 9,5/80, 70 and 60
C 7,5/70, 60 and 50
C 6,5/60, 50

Third class roads connect municipalities with first and second class roads. They also connects first and second class roads with each other on places where it's necessary. They have mostly local importance.

Ok, here are Estonian standards.

Motorway:
Project speed: 140km/h. Traffic density: >8 000 cars/day



I class road aka expressway:
Project speed: 120km/h Traffic density: > 6000 cars/day



II class road
Project speed: 120km/h Traffic density: 3000-8000 cars/day



III class road:(the most common one in Estonia)
Project speed: 100km/h Traffic density: 1000-4000 cars/day



IV class road:
Project speed: 80 km/h Traffic density: 200-1500 cars/day



V class road:
Project speed: 60km/h Traffic density: < 200 cars/day
