|Every traffic light in Assen. Note how the centre of the city and residential areas have no traffic lights at all. Most traffic lights are on main routes for cars, not for bikes. Some spots show more than one set of lights.|
There are many misconceptions about how cyclists use traffic lights in the Netherlands. In order to try to explain how cyclists really use traffic lights in the Netherlands, this blog post shows every traffic light in Assen and explains what interactions, if any, cyclists have with each example.
You will see from the map above that there are few traffic lights in this city and those which exist are almost entirely on the main routes for motor vehicles. Residential areas have many junctions but no traffic lights in them at all. The very centre of the city also has no traffic lights at all. Many journeys by bicycle can be made without interacting with traffic lights. It was a specific goal when building the new suburb of Kloosterveen outside of the city on the west, that new residents would be able to reach the city centre by bicycle without meeting any traffic lights along the way. Traffic lights do occur on the motor vehicle route from the new suburb to the city.
Traffic lights are to be found where there are most cars, not where there are most bicycles. In many cases, due to the unravelling of driving routes from cycling routes, these traffic lights are not used by cyclists at all so never cause any inconvenience. Most cycle journeys do not involve repeatedly stopping at traffic lights.
Traffic lights controlled crossing are also provided to help cyclists to make convenient and safe crossings of major roads.
In total there are 28 locations with traffic lights in Assen, numbered 1-26 below (with "a" and "b" used where there are two too close together to separate on the map above). They are classified as follows:
Pedestrian and cyclist crossings (1, 6, 13)
These lights are provided in order to improve cyclist safety when crossing potentially busy roads. While cyclists may find a red light when they reach one of these crossings, they never have to wait more than eight seconds (it's often less) before motor traffic is stopped and the light goes green for crossing. Junction one in a west-east direction is shown in this video:
There is also a traffic light at this location which occasionally stops both cyclists and motorists travelling north-south if a bus goes along the bus-road parallel with this cycle-path. However this defaults to green for both bikes and cars and provides only a very rare and very brief inconvenience.
Earlier videos demonstrate both junctions six and 13. These are just as convenient for cyclists as the crossing illustrated in the video above.
Simultaneous Green for bikes (9, 14a, 22, 23)
In Assen, traffic lights prioritize cycling. One of the ways in which this is done is the use of simultaneous green lights on which cyclists ride in any direction, including diagonally, across the junction with no interaction whatsoever with motor vehicles. These are combined with being able to turn right against a red light. Junction 22 is a mid-sized simultaneous green junction which has featured several times on this blog but this principle can also be used successfully on smaller and large junctions.
Where cyclists use traffic light junctions, the simultaneous green layout is the most convenient and safe way to do this.
|Cyclists using the secondary W-E route south of the canal use|
a simultaneous green junction. Those using the primary route
north of the canal have a bicycle road with no traffic lights
The main route for motor vehicles is also west-east in this location. The north-south route connects to residential feeder streets with lower traffic levels.
|Junction 4a. One of three in Assen|
where cyclists have a green light by
default and drivers wait for the light
Three junctions in Assen default to a green signal for cycling and only make cyclists stop if a driver has triggered a sensor. The intention is that it is normally the case that you ride over these junctions without stopping.
There are videos which demonstrate both junction 3 and junction 17.
Traffic light junctions which only exist for motor vehicles (7, 14b, 16, 18, 19, 26)
These junctions simply don't exist so far as cyclists are concerned. They regulate motor traffic along busy roads which provide routes for motor vehicles completely unravelled from cycling routes.
Previous blog posts cover how cyclists use an underpass so that they never have to stop at junction seven and how junction 26 exists only on the unravelled motor vehicle route.
Junctions 16 and 18 don't apply to cyclists at all even though they are in line with junction 17 which defaults to green for bikes. You can see them in this video.
Junction 19. On the other side of these traffic lights is the motorway. The only reason why you would reach this point on a bicycle is if you were that sort of vehicular cyclist who is determined to ride on motorways. There are far better routes North from Assen by bike than this one and they have fewer traffic lights too. View Larger Map
Traffic lights with only incidental interaction with cyclists (12, 25)
|To access the hospital from the city|
centre we follow the cycle path in
red directly to cycle parking by the
front door. It's only necessary to cross
using the lights from the South
Junction 25, at the hospital entrance, is a major junction for motor vehicles combined with a simple crossing for bikes.
Major road junctions with cycle crossings on some sides of the roads (2, 4b, 5, 8, 10, 11, 15a, 15b, 20)
|Junction 15a (15b is nearly identical)|
A major junction for cars. Delays are
short for cyclists and there is time to
cross all six lanes without stopping
in the middle.
|Junction five. In the video below, I ride|
from South to North here. Pink/red
show cycle-paths/my route.
Junction five is illustrated in the video below. This video also demonstrates the junction timing. Note how the delay before crossing is not long (these cyclists reached the junction only slightly ahead of me) and how when cyclists are given a green light, it stays green long enough that a large group can cross this major junction (in this case five lanes of traffic) in one:
Where there is a requirement for cyclists to be able to turn right, these junctions provide for safe right turns when there is a red light (a privilege which motorists don't enjoy in the Netherlands). It is very rare that anyone should have to ride across two arms of these junctions as part of one manoeuvre because in each case, another route exists.
Junction eight is really only a crossing so far as cyclists are concerned. It featured in a video showing children on a school trip.
Oldest junctions, soon to be replaced (21, 24)
|Outside the railway station. Cycle|
routes (not all are cycle-paths)
highlighted. This is being changed.
Junction 21 is an interesting example. It's the least satisfactory traffic light junction in Assen and because it's right next to the railway station, it's one of the first pieces of infrastructure that people see when they visit the city.
This is the closest example that we have of the sort of thing that seems to come to mind to many people outside this country if they try to think of what a typical Dutch traffic light junction looks like. It's actually one of the oldest pieces of infrastructure in this city, dating back to 1989 when the existing railway station was built.
|This junction dates from the 1980s. It's the most awkward traffic light junction for cyclists in Assen and often requires people to make a two-stage turn. Don't take inspiration from older infrastructure like this. It is soon to be removed.|
|In the near future, through motor traffic|
will be underground while cyclists
stay at ground level. No traffic lights
will be required so no more delays or
multi-stage turns for cyclists.
When this work is complete, this last of these older style traffic-light junctions in Assen will be gone. No traffic-lights will be required here once the main road is underground, greatly increasing convenience for cycling. The cycle-route between the railway station and the centre of the city will no longer have any traffic lights on it.
Places where there used to be traffic lights, but they're no longer needed
|The first traffic lights installed in Assen were here. They|
are no longer needed because this is now nearly car free
Like all city centre streets in Assen, and across the Netherlands, the streets in the photo on the right was dominated by motor vehicles in the mid 20th century. This was the busiest street in Assen and the first traffic lights in the city were installed here in order to deal with the traffic.
However, the city centre streets are now either completely car free or now nearly car free. They can still be used as a through route by bike but not by car. The removal of through motor vehicles meant that the traffic lights were no longer needed at this location or several others in the city centre, making cycling more convenient.
Watch a video which demonstrates this street in action in the 1970s and now.
How well does this combination of junctions work ?
Every junction in Assen, whether with traffic lights or otherwise, can be used safely by every cyclist in Assen. What's more, this infrastructure is not only safe but also convenient. Children, older people, those with disabilities all use the same infrastructure as confident adults and fast cyclists because the same infrastructure works best for everyone in terms of both safety and convenience. No-one is expected to choose between a safe route and a convenient route.
Of Assen's 28 traffic lights, six simply don't "exist" so far as cyclists are concerned. Two more of the local traffic lights have only incidental influence on cyclists. Three are provided specifically to create safe crossing points for cyclists and three more default to green for bikes so rarely cause slowing for cyclists.
An underpass built in the 1970s
allows cyclists from the east of the
city to pass under three railway lines
and two roads, and avoid the old
set of traffic lights by the station.
Just only junction is annoying to use - the old junction at the railway station which is soon to be removed and will no longer cause inconvenience. Even at this location, though, there are ways in which many people can completely avoid the delays caused by that junction.
Infrastructure that we don't have. Lessons to be learnt
|A current proposed design in|
New Zealand. In the 1970s
there was a road in Assen
which looked a bit like this
but this dangerous design
was removed many years
ago. This would never be
built now. Kiwis !
Please do not build this !
|The sort of thing that many people think|
of as a "Standard Dutch Junction". This
is again a proposal for New Zealand,
described as "Dutch" though it's not.
Again it's not something I'd want to
see. In any case, large junctions are
but a small part of the picture.
The junction closest in design to these that we have is the outdated example by the railway station which, as described above, is being removed. Yes, Assen is getting rid of junctions which look like that, not building more of them.
Badly designed junctions lead to inconvenience. They perhaps also result in a reduction in safety as people try to find more convenient ways to make turns across traffic without having to stop twice.
Unfortunately, the idea that there is such a standard traffic light junction design, that it looks something like this, and that it's something to emulate, has become popular. I've seen this idea pop up in many places. In this case, it's gone so far as to the other side of the world. It is precisely to help people to avoid making mistakes like this that we began running cycling infrastructure study tours way back in 2006. It's not too late for New Zealand's planners, or those from elsewhere, to avoid making expensive and dangerous mistakes. You can do a lot better than this. Contact us. Ask for advice. We're here to help you.
|Much more common than any traffic|

area, has a 30 km/h speed limit, raised
table, small corner radii, and most
importantly it's not a through route for
We often have people ask us how the Dutch accommodate their "huge" junction designs on minor roads. The correct answer is, of course, that they don't do so because they do not need to.
Most junctions are not "huge". Most junctions are not busy. This is by design. Most junctions simply are not on the routes of through motor traffic. You'll note from the map at the top of this blog post that Assen simply doesn't have many traffic lights, and large parts of the city contain none. Many Dutch towns are like this.
In reality, at the most common design of junction in the Netherlands there is very nearly nothing at all to see. However, this is possible for reasons that go well beyond merely how you design traffic light junctions. Minor roads and residential streets have almost no motor traffic on them. To a far greater extent than other nations, the Netherlands has removed opportunities for rat-running.
Cycling routes are unravelled from driving routes to a great extent, making routes for cycling more direct and allowing cyclists to avoid traffic light junctions on their journeys. The only junction at which stopping is irritating is the older style junction at the railway station. This is from another age and we won't have to put up with it for much longer.
Readers may recall that when I visited London last year I was frustrated with the low speed and stop-start nature of cycling in that city. Many places in the world are like London in this regard. By contrast, it is rare that I stop for a traffic light when cycling in Assen and that is how it should be. Journeys by bicycle must be continuous and direct.
If cycling is convenient as well as safe then people will cycle. Apart from the few traffic lights installed specifically to allow cyclists to cross roads, cyclists do not need traffic lights. What they do need is a very dense grid of very high quality car free, or very nearly car free, routes.
If you want to emulate the Dutch success you need to emulate the best of Dutch practice. Don't make or accept proposals for second best.
|Learn about real Dutch cycling infrastructure|
Assen provides an excellent example of how to do the right for cycling. This city has no university and therefore does not benefit from a large student population which would boost the cycling modal share regardless of infrastructure quality. Assen's higher than average modal share for a Dutch city (a higher cycling modal share than any city outside the Netherlands) has been achieved by investing in a very comprehensive network of better than average infrastructure which is constantly being improved.
On our tours we also visit Groningen, which for many years has been the top cycling city of the Netherlands. Different design choices were made in Groningen. There's also much older and less polished infrastructure than what we have in Assen. This gives an opportunity to compare how well different things work, to point out some errors and to show how older designs differ from modern designs.
We're independent. This means we are not supported by government or engineering companies. We can be entirely candid about what is good and what is less good. We have no commercial reason to push one idea over another, we only tell you what works.
Just like the traffic lights, all the roundabouts in Assen also work very well for cyclists. Read the older post "Every Roundabout in Assen".
