Speed bumps like in the pics above are pure madness. They're very dangerous expecially for cyclists and motocyclists. Driving on a dirt road damages your car less than those bumps. It's not in that way that you decrease road fatalities, rather improving law enforcement and suspending licences to who behave in a dangerous way on the road (that is a bit different than fining just to make money).

A2 Utrecht - Amsterdam

A recently released evaluation report of the first 10 finished road projects showed us some insight of the effectiveness of these widening projects.

Most notable was the reduction of traffic congestion on the A2 northbound between Maarssen and the Holendrecht motorway interchange.

Traffic congestion on this section was reduced by 98,5%

The motorway has been widened from 6 to 10 lanes. Even with a lower speed limit, the average rush hour travel time is still 60% shorter than before the widening.

No congestion = cleaner air. Take that, environmentalists.

Well there's a lot of induced demand for more road capacity so equating more or better roads with larger traffic quantities wouldn't be a lie.

Lots of people forget that this will also mean better traffic quality though.

Traffic is now where it belongs; on the safest road type; the motorway. The road itself doesn't create demand. Constructing 40.000 houses in Utrecht next to A2 does, though.

Traffic went up by 13% after the widening, at the same time traffic congestion fell by 98,5%. More traffic does not necessarily mean more congestion. The motorway capacity increased by approximately 65%. However, traffic growth is not as extensive as it was during the 1990's, so I tend to disregard those doomsday scenarios about more congestion due to a road widening to the fairy tales of the netherworld.

I can't beleive you wrote it. I'm sure you know very well that it is not true. Yes, a road always creates demand. If you build a new road or upgrade an existing one, there will always be people that think 'I can drive from A to B in 40 minutes now, let's accept a job there', etc.

Sure, but that's pretty marginal compared to the regular traffic growth due to spatial and economic changes. The effect of that is extremely blown out of proportion by anti-road advocates as if that's the only cause of traffic growth and congestion.

I assure you that if you construct a 2x5 motorway in the middle of nowhere between Harlingen and Leeuwarden it will not fill up with traffic. However, according to the "induced demand" theories it would fill up rather fast because the road itself induces demand.

Nice animation of the new A50 Waal Bridge near Ewijk (close to Nijmegen). They even have sun glare and bumps from the expansion joints in the video.

A27 Utrecht

I took some photos today of the A27 widening to 6 northbound lanes. Originally there were 4 NB lanes; 2 to A27 and 2 to A28. Now it's 3 each. It runs for about 3 kilometers between two motorway interchanges. It's one of a few 6-lane carriageways in the Netherlands.

Traffic congestion Q1 2012 down 30%

The Dutch motorist and tourist association ANWB reports traffic congestion in the first quarter of 2012 was 30% lower than in 2011, and the lowest Q1 since 2006. Especially the evening rush hours were less congested. The ANWB cites the good weather, poor economy and improved infrastructure. The worst congestion spot was northbound A4 near Leiden (which is solved as of today). The busiest rush hour was Tuesday March 20th with a peak of 271 kilometers, which was, a few years ago, about the average rush hour.

Although statistics from the ANWB are more meaningful then merely one personal observation, I can confirm this from my personal experience, driving weekly from the east to the west during the morning (Deventer - Rotterdam) and back during the evening. Exactly as you stated, delays are the worst during the morning (sometimes extending my journey by 45 to 60 minutes) while in the evening there are relatively few delays (maybe 20 minutes).

But still the holiday periods are the best, then you can get to your destination really fast.

The new A5 elevated motorway is slowly approaching the A10 Amsterdam Ring Road. Soon the decks above the motorway will be positioned into place.

I drove under this construction a few hours ago (A10) and i have to say that it is very impressive on the eye.

A4 Leiden

Yesterday, Sunday April 1st, the northbound lanes of the A4 near Leiden were directed through the aquaduct Oude Rijn, with an additional lane available. This was the worst traffic congestion spot in the Netherlands, but no congestion was reported this morning rush hour.

The works are now halfway. The six lanes of A4 are currently running through the 27.50 meter wide aquaduct. However, this is only one of two identical aquaducts, starting this week, construction of the second 27.50 meter wide aquaduct commences, which will be completed in 2014. The end situation in 2014 will feature 2x3 lanes through two aquaducts. There is space for 2x5 lanes.

So now we have a full 3-lane-per-direction highway from Dordrecht to Amsterdam

About time...

An article in the Volkskrant this morning (Dutch, here is a terrible translation, Note that the dutch word "file" means trafficjam, somehow Google translate decided to translate that in file... )

Anyway. the Volkskrant does not agree with most of you. Their line of thought can be summarized as follows:
  1. Congestion has decreased due to the extra motorway lanes
  2. People choose their living location based on the travel time to their work, not on the distance
  3. People move further away from their work as due to the lower congestion
  4. Congestion will thus increase again
I do not fully agree with this but I do think we cannot yet say whether the extra motorway lanes will have a lasting effect on congestion.
