Well, I guess it is just a a measure for "increase" security, as tunnels are considered more dangerous in case of accident.

Most of the tunnels I can remember have usually a lower speed limit than the generic limit on the rest of the road. But that's true that it depends on the particular case. Most of times

Anyway, many times lower speed limits without obvious reasons are finally quite arbitrary.

A1 HOV lane

Today it's exactly 20 years ago the first HOV lane opened in the Netherlands. This carpool reversible lane was constructed in the median of A1 between the Diemen interchange (A9) and the Muiderberg interchange (A6). Construction lasted 3 years and cost 62 million guilders. It opened on 27 October 1993.

The carpool lane was in operation for less than a year. Former transportation minister Westerterp was a vocal opponent of the carpool lane and stated he would drive in the lane alone and get a test trial. It worked and the carpool restrictions were scrapped in august 1994.

The reversible lane was widened to two lanes in 2011. It will be replaced by a new alignment with 5+2+5 lanes in the next couple of years.

A severe windstorm is affecting the Netherlands today. One station at Vlieland Island recorded sustained 12 Beaufort winds, which is hurricane-force. Even inland stations recorded 9 or 10 Beaufort, which is unusual. The highest gusts were over 150 km/h.

This led to chaos on the roads and the railways. Train services have been extensively cancelled and the fire department had thousands of calls in the last few hours. Many trucks were turned over by high winds, especially on north-south motorways, resulting in many bridge and road closures. Parts of the facade of towers across A12 in The Hague plunged down on the motorway, resulting in a closure.

This Polish trucker was not happy today. His entire combination got blown over at the A27 motorway. As you can see in the video, winds were very strong, road signage was also torn apart.


http://nos.nl/video/568018-boom-valt-op-rij-autos.html

This video shows a large tree collapsing onto parked cars in Purmerend.


http://nos.nl/video/568090-omvallend...n-zaandam.html

This is a stupid move, a guy tried to save is his car but the tree collapsed onto him and his car in Zaandam.

As you can see with most downed trees is that they fall over with their entire root system, they don't just snap off. This is because of the high ground water table in the Netherlands. Most trees don't grow their roots very deep.

N62, Sloeweg, Zeeland

The tender procedure for the widening of the N62 in Zeeland province has started. The contract will be awarded in early 2014 and full-scale construction will begin in April/May 2014. Preparatory works already begin next month to relocate utilities.

N62 will be widened from 2 to 4 lanes and provide full 4-lane access to the Westerschelde Tunnel. Separate projects south of the tunnel will also widen the N62 to 2x2 lanes, most notably the Sluiskil Tunnel, a twin-tube bored tunnel under the Gent - Terneuzen Canal. Breakthrough of the second tube is expected next month.

N388 closed due to massive tree-falling

Around 30 trees were blown over alongside the N388 due to the heavy winds earlier today. The road will be closed for through traffic for an uncertain amount of time. Cyclists will be able to use the road (the cyclepath is blocked, but due to car traffic not being allowed they can drive on the road itself), also emergency vehicles and locals will be able to use the road.

Transportation and environment minister Melanie Schultz went on a ride-along with truckers and attended truck inspections along several motorways with the police and ILT (Inspection for Living environment and Transportation). Statistics show 1 in 10 foreign truckers are exceeding cabotage limits, thereby competing unfairly with domestic trucking.

Schultz seem more attracted to these problems than her predecessors. She already vetoed a proposal to loosen cabotage regulations, which would have allowed more foreign truckers to participate in domestic trucking at wages Dutch truckers can't live off.

N69 Valkenswaard

Decades of talks have finally resulted in a final route of the N69 in Noord-Brabant province. Regional partners and the province have agreed on the route of N69 to relieve Valkenswaard of through traffic, which is one of the worst non-motorway bottlenecks of the Netherlands. Construction will commence in 2015, project cost is € 140 million.



N69 was actually planned as a motorway in the 1970s. The De Hogt motorway interchange (A2/A67) was originally built with a southward extension in mind, but this option was scrapped because it would affect the Dommel River area too much. The interchange was rebuilt between 2006-2010 as part of the Eindhoven bypass widening.

The current plan is called the "West Parallel", where N69 will turn northwest and connect with A67 near Veldhoven. A new interchange with A67 will be constructed.

Belgian N74, which is a motorway-grade 120 km/h road, dead-ends at the Dutch border, and traffic has to funnel down on a two-lane road through the center of Valkenswaard with near-constant congestion. Approximately 20.000 vehicles per day go through Valkenwaard. There is substantial commuting from Belgium to Eindhoven due to lower housing prices in Belgium and less regulation.

Those trees are planted too close to the road. Does not need to be a hurricane to make it happen.

Those are probably close to 100 years old oak trees and have been planted historically on main roads in The Low countries, many of wich now downgraded in The Netherlands because they have been bypassed by new roads. In Flanders the trees on busy routes have all been long gone due to overbuilding along those routes or widening of the old main routes yet some less busy roads remain such as the picture above.

It has little to do with the road. The ground water table in the Netherlands is very high, so the trees don't grow their roots very deep. The soil is so soft that trees fall over while taking a huge amount of soil with them, like this:

Actually, it has a lot to do with the road. The roads to not permit the roots to grow under them, so the trees do not have any support from the area which the road occupies. Hence, it will move back and forth when the wind comes in a direction that affect the sideways movement until the entire tree falls down.

It has primarily to do with old trees and roads yes, but it is very common practice to still plant the trees too close to the roads or not give them enough root space. The primary root space of a tree is usually in the top ten cm and quite often in the top three, so the water table issue is really not that significant. The roots that penetrate deeper than ten cm is usually not for anchoring anyway.

mobility balance, 2013

The KIM institute has published its mobility balance for 2013.

Some key findings;

* delays grew 55% between 2000 and 2008 but have since returned to 2000 levels.
* reduction of traffic congestion is nearly entirely attributed to road widenings, traffic levels are still growing.
* traffic congestion in the northern part of the Randstad was twice as high as the southern part of the Randstad prior to 2010. This area was prioritized and congestion dropped significantly more in the northern than southern part.
* expected annual traffic growth until 2017 is +1.5%
* growth of per capita driving is topping out, but not declining
* carpooling is declining, solo driving is up. Carpooling declined by 12% since 2005.
* solo driving is up by 11% since 2000, but less since 2008.
* growth of driving amongst young adults has declined, but car ownership did not. Reduction of driving among young adults is not expected in the future, current declines are due to the recession and lower job participation, not a long-term reduction.
* senior citizens are driving more.
* the rise of internet and social media does not result in less driving.
* train passenger kilometers grew 19% between 2000 and 2012. Almost none of this is due to a modal shift, effects are chiefly a larger population and higher OV-studentenkaart usage (free student travel accounts for 25% of public transport usage).
* cycling kilometrage increased by 14% between 2000 and 2012. Growth is nearly entirely attributed to the electric bicycle, regular cycling remained unchanged.
* freight transport is declining due to economic recession, 15% lower than pre-recession levels.
* 1/10th of domestic CO2 emissions is due to car traffic, emissions per car are declining, but are offset by higher car usage.
* the economic cost of congestion and accidents in 2012 was circa € 20 billion. Congestion cost in 2012 was down 14% compared to 2011.

What measures will be taken too discourage traffic from using the old road (which is more direct)?

It's freeflow with 2 exits. Only at Veldhoven there will be intersections. Well, probably, since that is part of a different project.
Check here for 'pictures' of the future alignement.

I still think it would be much better to draw it straight into A2/N2 at Knoopunkt De Hoog, may it cost some works on the river.

I hate it when roads are connected with corners... that's a perfect way to make people think the old straight road is better.
