What is the use of the "GAP"?

Wilhelm told it correctly, the Diesel boom was maybe a bad idea.
Someone who knows about refining crude knows that its not so easy to change these processes, especially in short term.

So at first that diesel was cheaper by lower tax on the fuel (in germany) led to a higher use, which of course increased the price.

Also it was the case, that the tax for the car was higher, whilst for the fuel it was cheaper. So everyone needed to decide where the breakeven might be.
If you had a bigger family thus a bigger car and could not afford drinving fast and for fun you would choose a diesel.

This means that a change in diesel policy would bite those peolpe with less money more, not those with sportcars of course. And the environmental zones are more strict for diesel, like discussed here. So for this kind of sandplay of the rich the poor suffer.

Of course in cities there is more public transport, something i encourage. But it took a while for example until there were special permits for transports if you were moving. Who was biten by the fact, that helping your child to start in a new city was impossible with your diesel car (no transport). You know it: Those unable to pay a company for doing the job.

By the way: smog means something visible. It can also be unhealthy if you don't see anything. To compare whith beijing.... well, is funny. Its like telling a beggar to be proud not to be eritrean. That might be true, but helps no one.

What is often forgotten, and i told it very often until know, is that children and retired suffer more in accidents with cars, the young don't drive themselves and not all of the old still can do it, even if the numbers increase. So the car-maniac policy is just unfair, because it prefers one group, which is strongest over alls the others. Public transport is much more fair.

If you think bigger, you can plan cities like in trumped america, where its impossible to go anywhere without car and where even sidewalks are often missing. Thats an physical environment where you are locked inside a car-maniac policy. But in europe there could at least be a financial lock-in. public transport cannot go everywhere. If the share is small, there won't be a close net.

The fact that i write here qualifies me for petrolhead i think

There are also hybrid solutions. So make public transport in dense areas very good en fine-gridded with free car parking on the edges for the people in the villages or the ones which like to make large trips once in a while. It's true that it means big investments for some countries like the US.
So for example my father-in-law which lives just south of Brussels in a village, it's impossible to get hence the nearest bus stop is 11 kilometers away, while the area is still densely populated with it's interconnected villages. They are (very slowly) expanding the light rail around Brussels to the nearest big villages to have this hybrid solution as it is cheaper than heavily expanding the bus network or upgrading the entire ring road of Brussels which is way over capacity. And has the advantage of being cleaner. But it does mean the public transport in the city itself must be very good if he wants to reach his destinations without completing a marathon each day.

In the Netherlands the Randstadrail is essentially this, although in practice it's more rebranding than actual adding connectivity (except for the metroline between Rotterdam and the Hague which has transfer point on the villages along the route).

The design of the tunnel is mandated by the Amsterdam - Utrecht railway, where it crosses underneath. They will fit the tubes under the existing rail viaduct, so that viaduct dictates the location of the tubes. This way they don't have to shut down or temporarily relocate the railway.

They said that the actual health concerns are more likely in your own house than along a motorway. Many houses are poorly ventilated, especially with cooking a lot of PM 2.5 is emitted. They measured values of up to 670 g/m of PM 2.5 which is 67 times over the WHO recommended limit, and far higher (Chinese-style) concentrations than what you'll find along motorways.

The research organization TNO stated that 90% of PM2.5 exposure is indoors, with significant spikes during and after cooking.

A13 Delft

Construction of rijksweg 13 (A13) at Delft in 1937. It was the first divided highway in the Netherlands, though it is usually not considered to be the first true motorway, as it had only one grade-separated junction at that time. A13 does hold the distinction for being the first six lane motorway in the Netherlands in 1960.

Now THAT is some green technology

Probably all that well-laid ballast is because of the watery soil around there

Also, notice the bricks. Early Dutch motorways had brick shoulders, brick ramps and occassionally even brick mainline pavement. The brick industry was quite big in the day and a good lobby meant involvement even in motorway construction. This faded out after World War II, probably in the early 1950s. The bricks were also important because of settlement of the embankments.

A12 Zevenhuizen - Bodegraven was built with a brick pavement in 1937. The rest of the route from The Hague to Utrecht had concrete slabs. Post-war A12 east of Utrecht also had bricks as far east as Veenendaal. It was one of the earliest motorway projects to resume after the war.

Bricks were probably discontinued in the early-to-mid-1950s. According to autosnelwegen.nl, the brick A12 east of Utrecht was opened in stages in 1949-1951, but it was replaced with concrete by 1956.

Using horses was still quite common at that time.

Trying to get my bearings with the A13 construction pics.
I think the first one is looking toward The Hague from aproximately where IKEA is now. I'm guesing the overbridge is at Zestienhoven?

The overpass is where the Brasserskade bridge is presently. At that time it was the only bridge over rijksweg 13 between The Hague and Rotterdam.

Brick kinda makes sense in a more closed economy, where clay is abundant, but stones are not.

A20 Rotterdam - Gouda

Minister of Transportation Melanie Schultz has started the plan approval procedure for the A20 expansion east of Rotterdam today.

173 million has been allocated to this project, but funding won't be available until 2023. It may be expedited to 2020 if South Holland province can pre-finance the project.

They are initially focusing on widening only the Nieuwerkerk - Moordrecht segment to six lanes. A study is also examining if it is feasible to expand all of A20 to the Gouwe interchange at A12, but it could create another bottleneck there, due to the Gouwe Aquaduct which doesn't have much space left.

They are also considering a capacity upgrade of N457, to get local traffic to the Gouda area off the motorway before it reaches A12. This could reduce traffic merging onto A12.

2016 traffic figures

Traffic on the Dutch motorway network grew by 3.1% in 2016, a total of 69.9 billion kilometers were traveled on the motorways.

Traffic growth was most strongly in the early rush hour and during the day.

Traffic congestion increased by 13.1%, but is more spread out than before. The number of intense bottlenecks has been reduced.

A4 at Leiden is the number 1 bottleneck in the Netherlands. This segment has a completely failed configuration of 2+1 lanes.

Traffic congestion due to roadworks amounted to only 2.9%.

Billions of vehicle kilometers traveled (2000-2016):

N302 / N23 Hoorn - Enkhuizen

Constructor Heijmans has now ceased all works on the N302 expressway between Hoorn and Enkhuizen.

There has been a dispute between Heijmans and North Holland province since 2015 over financial setbacks in the project which Heijmans thinks are due to the province. They recently moved the dispute to the Council of Arbitration of the construction sector. North Holland province has been urging Heijmans to move it to arbitrary for 1.5 years now, however a settlement may take a long time to reach...

The soil conditions proved to be more difficult than expected, which caused delays and financial losses for Heijmans. Heijmans thinks the province should pay for this. The province says Heijmans should pay for it.

There will be significant consequences for Heijmans if it loses the case. It risks a 10% fine of the contract value (which was 200 million) plus tens of millions of euros of unforeseen expenditures. It is the fifth problem project for Heijmans in a year.

The constructor Heijmans and North Holland province reached an agreement, the details of which are yet unknown, but construction will resume 'immediately'. The case for the court of arbirtration has been cancelled. The new completion date for N302 Hoorn - Enkhuizen is late 2018, which is one year later than originally planned.

This is good news, because the court case would've likely taken a year or more to reach an agreement.

Heijmans will release a statement tomorrow morning (before the stock market opens) detailing the impact on its finances.
