14 and a half feet please


View larger map
The image above is from a cycle path which I use for a good part of my commute. I've written before about how this path is great for commuting at a decent pace, and shown how this cycle path has priority over side roads. The cycle paths here are 2.5 m ( 8 feet ) wide, that's the minimum allowed for a unidirectional cycle path. Such paths should also be separated from the road by a minimum of 1.5 m (just short of five feet), however, in this case, the separation is actually about 4.5 m ( 14 and a half feet ).

Back in Britain there is currently a campaign called "3 feet please" (link is not longer correct), which is asking merely for motorists to give cyclists 3 feet ( 0.9 m ) of clearance as they pass cyclists. The campaigners behind this correctly notice that "Fear of traffic" (i.e. a lack of Subjective Safety) prevents people from cycling in Britain, but their suggested fix is woefully inadequate.

"3 feet please" didn't originate in Britain. It is actually an idea that the British have imported from the USA. The problem is that while this passing distance requirement is law in some American states, the cycling rate in the USA is just as low as it is in the UK. Britain copying America or America copying Britain is never going to result in a high rate of cycling (and you can add any of the other English speaking countries to this. Australia, New Zealand etc. They all have about the lowest rate of cycling it is possible to have).

It's no good looking to where people don't cycle to find ways to encourage people. You need to look to where people cycle a lot. The Netherlands leads the world by a wide margin. 3 feet is not enough. Complete segregation of cyclists from motorists is what is actually required to make the masses feel that cycling is safe. It's also required to make cycling efficient and safe.

This can be achieved by a combination of two means: high quality cycle-paths with proper traffic light and roundabout design, and by treatment of roads to achieve segregation without cycle-paths. The concepts of Sustainable Safety lie behind the Dutch success.

The Dutch highway code tells drivers to pass cyclists with a minimum 1 to 1.5 m gap. However just like everywhere else this doesn't mean it actually happens because just as everywhere else, drivers make mistakes. What keeps cyclists safe in the Netherlands is not tbe law but the physical infrastructure which exists where most cycled journeys are made. To learn from the Netherlands it is necessary to emulate the things which really make a difference here, not just anything which is "Dutch". Note that the example cyclists are shown riding side-by-side. That's normal in the Netherlands.
This infrastructure isn't only for high speed adult commuters. I also made a video showing how school children use this same cycle path to get into the city from a village. Note also that in this instance the cycle paths have a concrete surface which is smoother, and faster to ride on than the asphalt of the road. This type of surface is increasingly common in the Netherlands.

School cycling route from a village into the city


The village of Vries is about 8 km North of Assen. It is a village of fewer than 5000 people. There is no secondary school in the village so most children of secondary school age in the village cycle each day to Assen to go to school.



The school which is the shortest distance from the centre of Vries is on the Groningerstraat in Assen, around 8.5 km (5.25 miles) South. Not all of the children attend this school, some of the others go a few km further into Assen and some ride in the opposite direction to Groningen, about 18 km North of Vries. Some children sometimes ride a bus, but there is no "school bus". The schools do not have drop off zones for parents to deliver children by car, and arriving at school by car is extremely rare. These children predominantly cycle to school, as is the case all across the Netherlands.

The cycle path provided for this route is of very high quality and encourages cycling. I covered this cycle path before. It also forms part of the route of my commute to Groningen.

Even though in this case the driving route and cycling route are the same, cyclists only go through two sets of traffic lights, while drivers go through four. The difference was explained in a previous post.

If you want to encourage a higher cycling rate where you live, this is the standard of provision to aim for. Not only do children cycle in greater numbers here than elsewhere, but the same is also true of the entire population. The degree of subjective safety on cycle paths like those shown in the video is the reason why cycling here is so appealing.

There are many other school travel stories, and don't miss the video of primary school children riding to school.

Note that the google maps imagery of this route is a bit outdated, but what is on streetview is quite good.

Borrowing a velomobile


I worked at the ligfietsgarage today, a Saturday, as we had several people wanting to try the Sinner Mango velomobile.

The demo machine isn't needed until Tuesday, when I next work there, so I've borrowed it for the weekend and rode home today on the Mango, leaving my PDQ at work.

It's the first time I've ridden such a machine more than a few hundred metres, so I was timid with it to begin with as I started on the 31 km trip back home. As I grew more confident I was quite happy with speeds around 36-37 km/h, roughly the top speed I'd expect on the PDQ, but in the second half of the commute I started to get more used to it and went a bit quicker.

It doesn't initially accelerate very quickly, but your speed can just continue to increase. Wow, it's fast. In open stretches on the cycle paths between villages I was going along sometimes at 45 km/h without really trying all that hard.

When I arrived home, the elapsed time was just under 52 minutes, the best average speed I've done to date for the commute. If I was to use this bike every time then I'd get used to it and the average would perhaps drop a little on good days.

Several months later: I now own my own Mango.

I've previously shown my commute here and here, or you can see more velomobiles here.

A tale of three traffic lights

Heading back into Assen yesterday from the North I realised I'd not yet mentioned the efficiency of cycling in this location. There are three sets of traffic lights here within a few hundred metres, but they're (mostly) not for cyclists...

We're riding on a cycle path which is four metres ( 13 feet ) wide and separated from the road by a 3 m ( 10 feet ) green area. This set of traffic lights is for drivers who wish to use the motorway, which goes over the cycle path on a bridge just behind the camera. No need for cyclists to stop here.

This second set does have a light for cyclists, but it defaults to green for bikes. Drivers who wait in the right turn lane here or who are leaving the industrial estate on the right can trigger a green light for themselves and for the cycle light to turn red. Otherwise it will be green for bikes. I featured this before, with a video. Cyclists can also make a left turn here.

Now the third set. This again doesn't interfere with cyclists at all. No need to slow down or stop here on a bike. Neither cyclists nor drivers can make a left turn here, but drivers may have to stop to let other motor vehicles coming from the left merge. The scooter like vehicle on the cycle path is a three wheeled electric buggy which transports the rider in her wheelchair. People with all sorts of disabilities make much use of cycling infrastructure in the Netherlands. Next to that person on the right of the cycle path is a cycle only access to the industrial estate.

A video showing the three sets of traffic lights from the point of view of a cyclist:

The speed limit on this busy road is 50 km/h (30 mph). Cyclists are not expected to share the road with cars even at these relatively low speeds.

Maintaining priority in the countryside. How a route between a village and a city can be made extremely attractive for cycling.

A 2.5 m wide cycle-path of concrete, unbroken for 5.5 km in
length, with priority over all side-roads. This is unidirectional,
it's the same on the other side of the road. It's not called a
"superhighway", it's just a "fietsroute+"
and it took only €360K
from the local cycling budget to fund this (+€1.5M from other
sources).
On longer trips between towns, it's also important to maintain priority for cyclists so that journey times are not made excessively long.

This junction is on the main cycling route north from Assen to Vries. Note how the concrete surface of the cycle path, which is smoother than the asphalt surface of the road, continues through the road rather than the other way around. Also note the prominent give way markings (triangles) so that motorists are in no doubt about who has priority at this junction.

The raised areas with red paving prevent motorists from cutting the corner. The corner radius on the road here has been made deliberately sharp in order to slow down motor vehicles entering or leaving this side road.

The path has been upgraded to "fietsroute+" standard, which was publicised last year on postcards from the local government:

The only marketing was a postcard which listed the plus
points of the fietsroute+
This standard, as described by the text in the green dots on the postcard, requires that the route has:
  • Clear signposts
  • Easy and safe crossings
  • Minimum of 2.5 m wide cycle path (on both sides of the road, as each side is unidirectional).
  • Socially safe route
  • A direct route from A to B
  • Surface of concrete or asphalt with no or little roughness (but enough that you don't slip, of course).
On the back it reads "Cycling in Drenthe gets still more enjoyable and safer. Several cycle paths in our province are being upgraded to a Fietsroute+. Assen to Vries is the first"

"As well as the cycle path, the bus stops along the route are being improved. There is more room for parking bikes and later this year new shelters."

This stretch has been completed for some time, and work is now taking place on improving other routes to the same standard.

The effort put into these paths pays off in allowing cyclists to ride very quickly, take a direct route and to do this in great safety. The road which is paralleled by this route has an 80 km/h (50 mph) speed limit, but has relatively little traffic due to not being the signposted route for drivers and due to there also being a motorway which offers drivers the choice of 120 km/h.

Older junction before it was upgraded in 2009
The cycle path itself isn't new. Even having priority over side roads is not entirely new. This is an upgrading of an existing facility. This photo shows a junction on a cycle path alongside the same road some way north of Vries. This stretch had not yet been upgraded when this blog post was originally written. The older junction had some roughness as you rode over it due to cyclists having to use the less smooth surface used for minor roads relative to that used for cycle paths. With the upgraded cycle-path surface, the difference is even more extreme.

Here's an example of a van driver giving way to the cycle path. In this photo you can see clearly how at this junction the cycle path remains on the same level while drivers who wish to cross it have to go over a bump caused by the different levels.

This photo taken over my shoulder at an older junction shows a driver giving way as he turns into a side road. You can see how the cycle path is apart from the road at the point of the give-way. This allows space for one car length between the road and the cycle-path.

The new way to cross a side-road. Very clear priority for
cyclists.
Finally here's another photo of one of the newer junctions. It's not the same one as in the top photo, though it looks virtually identical.

These routes are extremely popular, both with commuting adults and with school children. A very fast friend who lives around the corner from me travels 30 km each way along this route to get to work in Groningen. At the same time, parents have few fears that their children will not be safe travelling on such a well engineered route.

How successful is this route ?
This section of cycle-path links a village of just over 4000 people with a city of 65000 people. While the target population for this cycle-route is not huge, this route is so attractive as a means of transport that more than a thousand cycle trips per day are made along. That is success.

How it looks in reality

The fietsroute+ features from one minute into this video. The preceding minute is of a secondary route which bypasses the city centre.

Two other posts about this route show school children commuting along it and going along in a velomobile at 40 km/h. Facilities like this are for every cyclist, fast, slow, young or old. Read more about fietsroute+.

The route features on our Cycling Study Tours. However, if you're impatient, you can get a glimpse of what it looks like to ride along it by looking at a series of stills and films that I put online here.
