That's a very basic traffic counter. It can only count the number of axles.

I installed double-tube traffic counters. These can also classify vehicles by type and by speed. Their data is very reliable as long as they are not vandalized. Light pole mounted radar counters are less prone to vandalization, but in my experience it is difficult to get reliable readings, especially if there are also cyclists on the road.

Typical traffic counters with rubber tubes don't register cyclists or children jumping on it, they don't displace enough air to be registered.

I've seen them in The Hague where they had stickers on them saying "Please don't vandalize this machine; it only counts the traffic, it doesn't fine anyone."

For some people that is an incentive to vandalize it.

I've had dozens of traffic counters vandalized. Because it keeps on recording, you can see when they were vandalized (often the tubes are cut with a knife or pair of scissors). Nearly all counters were vandalized on Saturday or Sunday morning between 0100 and 0500 hrs.

New billboards near A28 to be turned down on Sundays to appease ultra-religious community

Quote:
Two highway advertising hoardings close to the Bible Belt village of Staphorst will be switched off on Sundays, local companies have decided.

The screens will be attached to a 40-metre high telecoms mast next to the A28 and 30 local firms have set up a foundation to manage the advertising.

However, they have now decided not to use the screens on Sundays, out of respect to the staunchly Protestant local population, local broadcaster RTV Oost said.

There are stories that back in the 1960s, when A28 was just completed through Staphorst, people would throw bricks to passing cars on Sundays.

Chris, do you work for a Department of Transport in the Netherlands or something?

There will be 14 types of new traffic signs this year including for example:
*special signs to mark bus/tram lanes
*signs to mark trucklanes
*passing place signs



This is to make sure that there is one standard instead of every municipality making there own designs (or mix-match of current signs).

No, much highway engineering and consultancy in the Netherlands is done via private consultancies. We cater mostly to municipal governments. I worked mainly with traffic counting, highway design (AutoCAD) and air quality & highway / railway noise modeling.

N305 Almere - Dronten

Flevoland province for the first time uses styrofoam embankments at the N305 twinning project. It saves about three months in settling time. Not everybody is convinced this is a durable solution though. It isn't applied regularly in the Netherlands.

Is it a experimental project?

I've seen it used in some road projects in Italy, as a lightweight replacement for clay boggy soil. It is paramount that whatever is beneath the replaced mass is stable within the tension limits of the replaced material.

It is paramount that whatever is beneath the replaced mass is stable within the tension limits of the replaced material. It is particularly useful for things like ramps near viaducts. I don't know how to explain exactly the interaction of the force vector of passing traffic and the physical properties of the material, just that is is less prone to subsidence and lateral motion.

The DBFM (Design Build Finance Maintain) contract comprises the widening of the A12 between Ede and Grijsoord from 2 x 2 to 2 x 3 lanes and the maintenance of the stretch Veenendaal – Ede – Grijsoord for a period of 16 years after making available.

(...)

The work will commence at the start of 2015 and the widening of the road will be completed by the end of 2016. The maintenance contract will run until the end of the summer of 2032.

N7, Groningen

The final environmental impact statement (F-EIS) or 'tracébesluit' of the N7 Groningen expansion project will be signed by minister Schultz on Monday 29 September. This completes the plan approval prodecure.

The N7 project is the most anticipated road expansion project in northern Netherlands in decades. Earlier plans called for a new A7 alignment south of Groningen, but traffic studies found out the far majority of traffic on N7 has a destination or origin in the city of Groningen, and is not through traffic. Therefor, a new bypass would do little to relieve congestion in Groningen, but would have a very high cost.

The current plan will expand N7 in Groningen to eight lanes and become completely controlled-access. The Julianaplein traffic lights is the busiest traffic light in the Netherlands, processing over 130,000 vehicles per day. Because of urban constraints, it will be an 80 km/h 'autoweg' (expressway).

It's used frequently here in Canada. But it is interesting for NL... one would think light weight to be most important, to stop the country from sinking

N61 Hoek - Schoondijke

A new short four-lane segment of N61. It's a pity that they didn't twin the entire route to four lanes.

I don't get why we don't have a EU standard for those signs...
