Segregation Myths #1

There are a few common canards used to attempt to discredit anyone who dares to talk about going Dutch with respect to cycling infrastructure here in the UK, including:

1) We'll never get segregation on every street.
2) There isn't room on British streets for separate cycle facilities.
3) People need somewhere to park their cars.


1) We'll never get segregation on every street

In The Netherlands (and Denmark for that matter) they don't even come close to having separate facilities for cyclists on every street. Instead they have specific guidelines for how much separation is required in a given location (Separation Principles) based on factors including the importance of said route as a main commuting route for cyclists, the volume of motorised traffic on said route and the speed of motorised traffic on said route. The degree of separation increases with all of these factors, from zero segregation on a quiet service road up to wide separated cycle lanes all red traffic signal phases at functions to allow cyclists and pedestrians to turn in whichever direction they wish at junctions, or roundabouts with radial exits and legal priority for cycle traffic.

An advantage of this type of infrastructure is its calming effect on motor traffic, due to the reduction in motor traffic capacity. This has obvious benefits for pedestrians without bringing cyclists and motorists into conflict in the way that conventional lane narrowing does, as it is usually implemented without any serious consideration for the needs of cyclists.

2) There isn't room on British streets for separate cycle facilities.

Now that we have addressed the myth that Dutch-style infrastructure means putting a separate cycle lane on every street, we have gone a long way to addressing canard number two. The roads which most unattractive and unsafe for cyclists at present are the very same roads which have require the very highest level of separation of cycle and motor traffic under the rules of the Separation Principles. These roads are the widest and fastest roads we have, roads which are easily capable of accommodating Dutch-quality separate infrastructure for cyclists. In Manchester, good examples of roads matching this description include Upper Brook Street (A34), Oxford Road (B5117), Princess Road (A5103), Chester Road (A56) & Regent Road (A57), to name a few. Reducing the speed and volume of motor traffic reducing road capacity on these streets has wide-ranging benefits to pedestrians and the local community in which these roads are situated.

Unlike current approaches to tackling motor traffic speed and congestion through road capacity reduction and lane narrowing, using the space taken away from motor traffic to build Dutch-quality infrastructure does not necessitate bringing cyclists and motor traffic into conflict and so enhances the attractiveness and convenience of cycling rather than further diminishing it.

3) People need somewhere to park their cars.

Ignoring for now the obvious oddity that is the widely accepted phenomenon that is the routine storing of personal property on the public highway, in addressing canard number two, we have gone a long way to tackling this one too. The streets I named are generally of the kind which have either blanket parking bans, or at least have peak-hours parking bans along most of their length. The biggest roads are the roads where parking is already prohibited all the time, and where it is not prohibited all the time, it definitely should be (I'm looking at you, Upper Brook Street).

Even if implementing Dutch-style infrastructure did mean displacing some established car parking, I don't see why this should be regarded as a problem. It is a very depressing prospect that the safety of vulnerable road users be regarded as a lower priority than the publicly-subsidised storage of personal property on the public highway. Streets are primarily intended for people and movement, not storage.

  1. The whole principle of increasing non-motor movement is reallocating the ability to move from motor vehicular modes to non-motorvehicular modes.

    In London it was the Congestion Charge that gave cycling it's big push (followed by the tube and bus bombs) by changing the cost of motor vehicle use. Manchester failed to follow the same route.

    How you actually do this is probably best worked out on a case by case basis. My favourite is simply closing roads to motor traffic altogether.

    The day that motor vehicles are banned from Manchester's Oxford Road will be the day that we begin to hope that sanity has prevailed...
