Rotterdam had an excellent opportunity to do some proper city planning after its city centre was completely bombarded. Unfortunately we decided to return to the old plans, and now they're surprised everything is always locked up. There were some pretty cool plans, I'll see whether I can dig them up if anyone is interested (not really Traffic Engineering any more, more like Urban Planning. Oh well!)

Rotterdam is quite a relaxed city to drive in, traffic isn't that bad except on a few roads like the s'gravendijksewal which should obviously be a tunnel along the entire length and the Coolsingel where cars should not be allowed period.
Also city traffic engineers should probably stop making the green light cycles extra short to discourage car use (they actually admit they do this).

Also i was under the impression that at least in the city center they didn't return to the old street plans which is why everything is on a much larger scale than other Dutch cities.

Even 15-20 minute delays is still pretty horrible from a commuter POV, as is having to drive 30 minutes out of your way to avoid them. You're a government servant; if the public demands a plan B, you might need to go to plan B.

Then again having the bridge collapse under me is also pretty horrible. From what i get from the article there is no reasonable plan B. Bitching about the unavoidable is just childish.
And i agree with GWBBQ, anyone in a high traffic area would gladly pay to have only 15 minutes of delay on their commute.

edit: Come to think of it, how much capacity could a ferry have over the distance of a bridge span? I assume renting a ferry + temporary dock is cheaper than a temporary bridge. Unless of course there is a lot of shipping on the river.

Over here the biggest factor is noise.
Pretty much all new roads are paved with ZOAB (Very open asphalt concrete). It is much more expensive than concrete or even regular asphalt and only lasts 7 years but it has quite a a extreme reduction on the ammount of noise. Last week i drove on a concrete road and i can't imagine driving on those everyday, even for just a few kilometers the noise was maddening.

How often do people from your department go out to check whether as road has been opened? As far as I could understand (google translate isn't working and my Dutch is pretty rusty) it resulted from the ministry thinking the road was already open while the agency waited for the ministry to process the necessary paperwork. A lack of mutual trust in the competence of the other party goes a long way.

It also helps that situations like this are fairly common, finished roads that cannot be used for some reason. The tunnels in the A2 by Utrecht Leidsche Rijn have been done for quite some time but won't open until 2012. The Schwalbe tunnel in the A73 has been open/closed/open/closed again and again. And driving through the country there are a lot of pieces of road that seem to be waiting for the permit open.
So i can imagine everyone assumed it was another piece of finished road waiting for a permit.

Slightly off topic, but traffic related, what do folks think about the standard work day of 5 eight hour days turning more to 4 tens? It would save a day of commuting for people, but I don't know how productivity in certain jobs would be affected. Perhaps congestion wouldn't change too much as industries vary so much in regard to hours of operation and workplace population. Some of the major large industries here (primarily Boeing) seriously affect traffic when shift change comes around.

This is fairly common in the Netherlands. Except we only work 4x9 because we're lazy communists.

I read it only takes a 10-20% reduction in traffic volume to completely eliminate traffic jams (at least that is the situation here). You can really notice Monday and Friday are not as busy any more because most people prefer a long weekend. Tuesday and Thursday are the busiest days.

Bicyclist think no traffic rule applies to them.
It is really hard to be held liable for a accident as a bicyclist. Even while pulling a illegal manouveur if a car hits them it is fairly likely the car driver will be held liable. He should have expected the cyclist was insane and going to pull some suicide move and adjusted his speed to that. I'm not bullshitting, if you can read Dutch here is a example of a case where a bicyclist made a illegal dick move and the tram driver that hit him was still held liable.

The idea is that the guy piloting 1+ ton of steel has a heavier responsibility to other road users.

Isn't the point of speed bumps to improve safety? Seems like such a drastic system would cause more accidents, injuries and possibly deaths than it will ever save.
Most people who speed do not in fact crash. Things are different when they hit a 6inch high steel plate on the other hand. Seems like at best hundreds of dollars worth of damage and at worst death is a bit of a stiff penalty for speeding.

Induction lights use 1/3 the power of sodium lamps and go about ~10 years before needing a replacement bulb. Not as efficient as LED, but the light they put out is almost the same as daylight, doesn't degenerate over time and doesn't have that subtle "shining" effect you get from LED lamps. Until some of the kinks involved with LED lighting are worked out (dimming, voltage flux burnout), Induction is the best product on the market.

I haven't seen induction here anywhere but LED is going up all over the place. A lot of tunnels have LED lighting now that consist of 3-4 strips op LED running along the roof, the dimming issue is solved by just turning on or off more strips.
I think this picture was already posted in this thread but since it is relevant to the current topic here it is again: A44, old and new lighting side by side.

Do variabele toll rates (like the one in the picture where the toll changes from day to day) work? I can understand a peak usage rate, like during rush hour toll is higher than off hours. But if i am on my way to work or a customer and i see the toll rate has doubled (especially if it is on the order of cents) i am not going to turn around. Even if for some reason it was suddenly $10 i'd still keep going.

If you rear end the guy in front of you at a stop light because you didn't anticipate he could stop (for a traffic light, who would have guessed?) you were going way to fast anyway or didn't keep enough distance and are a bad driver.
These cameras will probably educate people in Toledo on properly anticipating traffic.

The Netherlands has started using section control on the A2. Cars are photographed when passing under a portal entering the section of highway, and is photographed again exiting it. If the time in between is less than the distance divided by the maximum speed, then you have speeded and get fined.

A2 wasn't the first to get it. The (previously) 80km/h part of the A13 has it as well as well as the A12, A4 and Zeeland bridge. It is especially annoying on the A13 where speed just drops to 10kph below the limit and people feel it is now OK to keep a 2 meter distance between cars. 70kph isn't very fast but those few kilometers are still the most uncomfortable to drive in the entire country for my money.

On the A2 it is just ridiculous because it is the widest road in the country with 5 lanes each way, less than 50% filled to capacity and now limited to 100kph.

edit: Good thing is that speeding doesn't have any real consequences other than money. Anything up to a 30kph violation after correction (for inaccurate measurement, usually a few percent) or 40kph on the motorway is a administrative sanction. Cost you money but no points on your license. You could be ticketed doing 40kph over the limit twice a day and nothing would happen other than loads of fines.

There is a regular crosswalk here in town with just a sign and the zebra striping. a few weeks ago they removed the zebra striping but left the signs (i guess just for maintenance or something) and people didn't stop at the crosswalk anymore. They put in the zebra striping again and now people stop again.
Personally i also wouldn't stop for some bright flashing light and a dude in workman gear by the road (not making any indication he wants to cross), i would probably just assume "construction ahead".

As a driver if part of the road markings are missing i am going to ignore the confusing or half finished signs you put up. Shouldn't you disable the strobes until the crosswalk can be finished to spec?

Doesn't throughput increase when you lower the speed limit (to a certain point)? That is one of the reasons many motorways near cities have been limited to 100 kph (the other is air quality), in a area with a lot of exits and merges a lower speed leads to more efficient merging.
I hate those narrower lanes like the ones they have on part of the A12. I understand that it is a great way to skirt the environmental impact analysis but you end up with a road that costs almost as much as a full size road that is extremely unpleasant to drive on.

They mark roadside cameras for measuring traffic flow and air quality as such here to prevent people from panic braking and also to prevent them going up in flames. They aren't as hardened as actual traffic cameras (though even those sometimes need cameras to watch the camera).

We would probably see people drive a lot slower. The past few years i see more and more people who are not driving at the speed limit or even slightly below it. 110 kph vs 130 makes a big difference, my car seems to be most efficient from 70-90 kph where ~3.5L per 100km is possible, at 130 kph this increases to ~6.5L per 100km.

To be fair at 500lbs you should not be comparing them to a big truck but a small car. I'm sure there is a niche for those and i see comparable vehicles on the road here.

My experience with average speed controls is that they are the worst part of my trip when i encounter then even if i am not speeding.
Everyone sets their car to cruise control "their" 5kph under the speed limit. But because everyone's speedo is calibrated different this also seems to turn people into tailgating assholes. So you end up doing 125kph with a car 5 meters behind of you and 5 meters in front of you while people also feel they can now overtake on the right because gently caress you i am doing the speed limit.

Or during more quiet times you end up doing 133kph and are one of the lucky 2000 people per day (per controlled section) who gets to pay their €47 extra taxes. Especially on the A2 which has a design speed of 160kph but a speed limit of 100kph.

It is the same with people stuck in the left lane going 10mph below the speed limit. There is no malice there, they just don't give enough of a gently caress about other people to be inconvenienced by moving 5 meters to the right. I have my car set on cruise control and i guess i am going to have to move to the left again in a few miles so why not stay in the left lane and dedicate spare brain cycles to whatsapp.

What about a hybrid law, like allowing bikes on sidewalks but with strict speed limits (10mph) that get stricter when passing pedestrians (like no more than 5mph delta to pass a pedestrian)? And likewise, minimum speeds on public roads, and outright prohibition from roads with speed limits higher than a bicycle can reasonable go. With such provisions enacted, bicyclists could be permitting on both sidewalks and roads depending on conditions and speeds.

How would you ever enforce this? For one most bicycles aren't even equipped with a speedo. Even if it has one it is not calibrated.
Enforcement would be hell, most police departments do not have equipment for enforcing such rules, even if they had it the calibration would probably not be valid at such low speeds. Since your suggestion specifically mentions a difference in speed we not only need to laser/radar the bicycle but also the pedestrian, at exactly the same time.

Sidestepping the question if moving bicycles to the sidewalk is desireable it is clearly not practical. The only real goal of such a law could be to throw up as many barriers to entry for cyclists as possible.

35mph is not that fast, fastest roads you are expected to share with cars in the Netherlands is 60kph (37mph) (often not even with a painted bike lane). Perfectly safe if drivers are well educated. I personally don't feel unsafe biking on a 37 mph road without a helmet.
edit: Not that your rule would help for these roads, these are mostly country roads and farm acces roads, they don't have a sidewalk either. My solution for your suburban scenario is to reduce the speed limit of the road to 35 or 40 mph, narrow the lanes and put in a painted (not fully segregated) bicycle lane. Should cost no more than repainting the road surface.

People get ticketed for speeding on bikes in New York City (the speed limits are set identical for cars and bikes, and it's easy to tell if you're on a bike and easily outpacing free flowing traffic). Plus your average police-issue rader equipment in the states is more than capable of reading down to 10 mph and working against bikes - the cops in my hometown used to let kids do speed-tested races with the cops announcing winners based on the radar gun results and that even worked for like 8 year old kids running on their own.

It is not just a question of can it read down to 5 or 10 mph but what is the margin of error at those speeds?
I've only had tickets with hard proof before because for a cop to actually write a ticket based on eyeballing or pacing you you need to be speeding a lot. Even if this is common practice in the US does anyone really believe a cop can look at a pedestrian, look at a bicycle passing the pedestrian at the same time and accurately estimate the difference in speed? This seems very incredible. Especially since the difference between a correct speed and speeding 50% is only ~3 mph.
edit: a fixed 10mph speed limit would be enforceable, but i don't see how you can enforce the 5mph difference rule.

How would you write a speed ticket for a bike anyway, not like they have license plates. Chase down and stop every single person speeding? That seems kind of expensive.

Pedestrians are walking, a dude booking it on a bike is fast. It's not hard. The intention of the 10 mph limit would be that reckless bikers are going to do significantly more than that.


But you know a cop is just going to park near a busy sidewalk and just ticket every single biker. So why not keep the law as it is (bikes don't get to use the sidewalk)?
Since appearently "From a distance of 400 yards and a angle of 30 degrees i estimated you were doing 10 mph and the person you were passing was doing 3 mph, here is your ticket" is sufficient proof.
The solution to people using a healthy environmentally method of transportation that don't have a place to go on the road is not to make that method of transportation less appealing by restricting their speed and making them subject to arbitrary fines and require them to purchase additional equipment (a speedometer).
Why not let them continue to use the road? Just because it annoys some drivers? They will get used to it.

edit: As someone who drives a car motorcycles annoy me, i'm not lobbying to have them moved to the sidewalk or bicycle path and restricted to 20mph. And i don't think anyone is going to argue motorcycles are way more dangerous than either bicycles or cars.

As part of the urban renewal program for the Bijlmer they actually lowered a bunch of those raised "dreef" roads in the Bijlmer. It was found that the lack of (car) traffic along some roads lowered the feelings of safety.
Bijlmer was sort of a urban planning experiment that didn't work so well. Amsterdam has been reconstructing and rebranding it for a few decades now. They demolished a lot of the huge high rise appartment blocks (think banlieu style blocks with similar social problems) and have been transforming the road grid to a more traditional system. Also they don't call it Bijlmer anymore but rebranded it to Zuid-Oost (South-East).

You can park in the city center in any city. Amsterdam, the Hague, Utrecht. It just isn't very cheap, up to €7 a hour in Amsterdam.
For big purchases it does help if your shop is car accessible.
