Road marking experiment on road 54 Lahti-Riihimäki. The idea of the double marking is to keep the opposite traffic flows more apart. No analysis published yet.

A double center line is the standard road marking on two-lane roads in the Netherlands (usually a continuous line, banning passing even on straight and clear sections).


N331 Vollenhove - Zwartsluis-5 by European Roads, on Flickr

The lanes on an 80 km/h road in NL are only 2.75 m wide (between the center and edge markings). Trucks barely fit within the lines. I assume they are a bit wider in Finland.

I think the double center line may produce safer two-lane roads. People are less likely to drive closer to the center of the road (thus closer to opposing traffic). Even if you straddle the center line there's still some space left, it could reduce the amount of head-on collissions.

How common are they? (According my experience, most of the Norwegian road network is too narrow to allow such an arrangement.)

In Norway it is quite common to have a 10 cm rumble strip on each side of the yellow centerline. According to the Norwegian Public Roads Administration (Statens Vegvesen), the rumble strips have reduced the number of fatalities and serious injuries by 60%.

But the case was not about the rumble strips but about the double centerline 70-100 cm in between.

I know, but you said the roads are usually too narrow for 70-100 cm of centerlines, so I just explained to you how it actually is in Norway

So you are completely right, we unfortunately do not have space for that kind of center "lanes", but at least we have something to compensate for it. And it works quite well, too.

There are roads in Norway with double, widely spaced center lines. Not sure when they first appeared, but it's at least 10 years ago.

Yup. 10-metre-wide expressways were fairly common builds over here in the 70s, 80s and 90s. Quite a few have been rebuilt into motorways, but the remaining ones - originally 1.5+3.5+3.5+1.5 - have been remade as 1+3.5+1+3.5+1 roads. That is also the current standard for new main road projects with an AADT of 4-6000 (8000).

Why not use the swedish solution? Looks far better than any easy-to-cross lines.
(yes, the same barriers are used on 1+1 sections too)

Cheaper without the fence than with it. If a comparable decrease in accidents is achieved without a fence, then the fence is not needed. Well, finding that out is one reason behind the testing anyway.

Also there are times when overtaking is not supposed to be prohibited, only discouraged. And of course (minor) accidents with might only require temporary closure of one lane.

[QUOTE=Alexander Kanavin;132568407]

Most of the 2+1 roads in Sweden are those 13 meters wide roads which were earlier 1+1 with wide shoulders. They do not meet the Swedish standars for new roads. Sweden has not built many new 2+1 roads. The upgrade was rather cheap but building a new road to meet the standards is not.

The minimum width of a 2+1 road with a barrier in Finland is 13.50 meters. This is feasible in a few cases only: The probability to meet a tractor on another agricultural device should be minimimal. The default minimum width 15.75 meters.

All Helsinki region's road infrastructure projects were delayed 10-25 years including Ring III/E18 3rd phase that was going to start this year (only Klaukkala's by-pass, half-reduced to 1+1 and Tuusula's by-pass (northern section, the southern one that exists will remain 1+1 with it's expected 30 000 ADT)... This for financing giant f-ing tram projects -.-' This is all linked to pacts of Greens supporting some things the National Coalition wants (like NATO).

The upgrade near Oulu was last year planned to be 2x3 for 12 Km's, now just two lousy on-off-lane-sections, and Lahti by-pass will be 1+1 most of t it lenght and without an interchange with the city's main street (will happen the same as in Tampere, a need of upgrade to 2x2 in 1 year that will be constructed after 20 years...). The 2+1-section north from Oulu that will be constructed has already ADT 15 000.

Turku ring (E18) eastern section upgrade to 2+2 with 12 000-20 000 ADT nowadays will _maybe_ be financed. Finland has betrayed the EU in fact; E18 was accorded to be entirely motorway by 2015. This must be the first time Finland betrays the EU...

I mean, absolutely ridiculous and stupid! Lipponen's cabinets giant motorway projects were a success on economy and uneployment rates; you can't just save and not invest at all (investing on bikes and trams is not valid investing nationwide or even city-wide at all).

The only hope for Ring III and the 3rd lanes between Klaukkala and Ring III on 3/E12 is that Vantaa finances them by herself, like Ring III 1st phase and like Espoo is financing Ring I reconstruction on it's southern part, it seems, by 2022, up to 1 from 51, though Espoo is a rich city...

Helsinki city planning council insists (led by Greens and the National Council) on converting all city accesses into 1+1bus+tramx2-lane "boulevards". Despite several critique from city planners and normal people living outside the city center, the council's spokesman says that Helsinki does not want people from outside it's boundaries in cars and said all critique is ridiculous.

This is how elitist Greens can get.. Helsinki will in the future be built only for 20-35-year-old persons who are all in excellent conditions. No seniors, disabled, families, commuters etc, only hipsters. The main argument used by the spokesman was that this will help to open new cafes (!)! You'll have to carry your TV in your bike. The spokesman expressed an ambition of the most radical anti-car-plan worldwide.

The National Coalition supports this because Greens agreed to spare a golf club near the center, and because frankly said it's leader in Helsinki Männistö is a jerk. The party will split in half. If they use enforcement, they will lose to the Greens in the 2017 municipal elections. This could be used by SDP, whose voters live outside the center.

Very brave, because the state has warned several times the council for this plans. I hope it will also use law enforcement for prohibiting the destroy of nationwide important and European routes.

After this exit and the exit 18 currently under construction are complete, the only remaining unused exit numbers on 3/E12 will be 5 and 44. Neither of them will be taken into use in the near future, because the respective projects are in the inactive state.
