When we were in Britain last October we drove from one of our parents to the other. It was an interesting experience being back on Britain's roads and making a long journey by car. One of the things we especially noticed after our absence from Britain's roads was how attempts had been made to limit speeds on roads through villages, but that they were inadequate. Speeds remained too high, and conditions for cyclists and pedestrians remained unpleasant.
The example above is of the A153 entering the village of Coningsby in Lincolnshire, and that's the example I'll use in this blog post. There are hundreds of villages along similar roads in the UK. but this is the one by which I stopped and took some photos:

Dangerous British example: Cycle on the road through a pinch point with 40 mph (64 km/h) motor vehicles. |
The national speed limit of 60 mph ( 100 km/h ) applies along most of the length of the A153. On entering the village this falls to 40 mph ( 64 km/h ). A reduction in speed is encouraged by signs and a central reservation which doubles as a space for pedestrians to cross the road, though there there is nothing other than grass verge to walk on if you reach the other side of the road.
The A153 has no parallel cycle or pedestrian path. Anyone who wants to travel the 4.5 miles between the next village, Mareham-le-Fen and this one has to use the road. Many journeys are made between villages separated by this sort of distance in order to shop, use sport facilities, go to school or to commute. Coningsby is a desirable destination from Mareham because there are more shops and other facilities in this larger village. However, because cycling along here means being overtaken by vehicles travelling at 100 km/h, very few people would consider it. We stopped for several minutes to take these photos and no cyclists or pedestrians were seen. Everyone who was making this journey made it by car, van or truck.
Where there are two vehicles heading in opposite directions, there is very little room for a motorist to overtake a cyclist.
A few metres past the 40 mph speed limit signs there is a central reservation. It is narrow and does not require drivers to divert much from a straight line. Many vehicles are still travelling in excess of the speed limit when they reach this point. Calls can be made that drivers should slow to well below the speed limit when passing a cyclist inside the pinch point, but they won't be heeded. The result is that anyone on a bicycle will be passed extremely close by a motor vehicle which arrives in the same place at the same time. This does not make for a pleasant or safe experience when cycling. Alternatively, the cyclist can "take the lane" and attempt to force motorists approaching from behind to brake sharply, but this also is doesn't make for pleasant or safe cycling and causes resentment amongst drivers.
This design of road, and this design of traffic calming, is lethal. What's more, given the high speeds that remain through the village, it doesn't even result in particularly pleasant conditions for those who live there.
The reason why this particular feature of the road grabbed my attention was that a few days previously I'd pointed out something very similar in concept to the
study tour group from Vilnius when they visited us in Assen.
If you had heard only a description of these two roads and not seen the physical reality then they would probably sound like almost the same thing. However, they are not the same in practice. Here is the "equivalent" traffic calming design in Assen:

The Witterhoofdweg has a speed limit of 60 km/h ( 37 mph ) before the signs and 30 km/h ( 18 mph ) through the village. This is the speed limit through most villages in this area. A third of the Dutch road network now has a speed limit of 30 km/h or lower.
|
Safe Dutch example: Speed limit is 30 km/h (18 mph) and cyclists have a completely separate cycle-path rather than riding through the pinch point with motor vehicles |
The central reservation is much larger than the British example and requires drivers to change course quite dramatically as they drive around it. You couldn't drive through here at the speeds at which drivers in Britain routinely enter Coningsby.
The reservation is 4.5 metres wide, meaning there is ample space in which to wait to cross the road even with a loaded bicycle. On the other side of the road there is a cycle-path which you may well want to reach. Now how on the left side of the photo you can see the three metre wide cycle-path which continues the entire length of the village, even though the speed limit on the road is 30 km/h. At junctions with side-roads in the village, the cycle-path has priority. This results in a continuous, convenient and stress free experience for cyclists.
Looking in the opposite direction we get a good view of the cycle-path as it enters the village. The complete separation of cyclists and drivers ensure that making cars swerve to slow them down doesn't in any way endanger cyclists passing this point at the same time.
For most of the distance from Assen the cycle-path is separated by too large a distance from the road for it to easily appear in photos taken from the road. This cycle-path is four metres wide.
At the opposite end of the village there is a similar traffic calming construction. Cyclists retain a very good degree of
subjective and actual safety right through this village and out the other side.

At the time when we took this photo it was a cold winter day in the Christmas holidays. However, there was a regular stream of cyclists, as there always is. When the schools are in session, this is part of a route taken by thousands of children each day who ride their bikes from villages to the South West of Assen into the city. Witten, where these photos were taken, is just 3.6 km from the centre of the city. However, this is merely the half way point to the next village, Bovensmilde, which is 6.6 km away - almost exactly the same distance as Mareham-le-Fen to Coningsby, and many people travel along here by bike from other villages considerably further away than that. Because the distance can be covered on cycle-paths, the experience will be pleasant and safe when doing so, and it's convenient to cycle, people cycle.
Written descriptions of these two traffic calming devices would sound the same. However, in reality they are different. Aerial views of both traffic calming features to the same scale:
Coningsby. The signs are above the top of this view, the central reservation is just behind the truck. No need to divert at all while driving through here. While there is space for a cycle-path, none has been built - View Larger Map
Witten. The signs are very close to the central reservation (see shadows to the right), motorists have to divert from a straight line to cross this point. Cycle-paths lead in all directions, all separated from the road, some by a considerable distance - Grotere kaart weergeven
Now I expect some readers to point out that the A153 is a larger more strategic road than the Witterhoofdweg. They'd be right of course. But larger roads in the Netherlands have rather more care taken to preserve the rights of cyclists and pedestrians to go about their everyday business in peace, not less. A traffic calming feature like this simply has no place on a busy road like the A153.
In Britain, the same ideas have been used as in the Netherlands, but they are often applied in a much weaker way, and often in staggeringly inappropriate places. That is what the blog posts tagged "
lost in translation" show.
