The logic is simple and obvious - the greater the amount and speed of motorised traffic, the greater the need for safe and high-quality cycling infrastructure. David Hembrow explores this logic further with a recent post on his blog.
But behind this policy lies a wider approach to urban planning. Residential streets are designed for residential use, and road planning ensures that rat-running, the scourge of many of Darlington's streets, is simply not possible.
A few examples of this have appeared in Darlington, notably on the Haughton cycle route on Brunswick Street. But this is the exception rather than the rule for residential streets. Developing a cycling culture in Britain requires town planners and politicians to consider urban development more holistically. Cycling cannot simply be bolted on to an existing plan. Rather it needs to be an integral, and contributory factor, in a wider vision for residential streets, urban mobility, and the place of motorised traffic in our living spaces.
The opportunity is now there for Darlington, and other UK towns, to adopt just this approach, with Local Transport Plan 3, which will frame future transport thinking until 2025, now under consideration. But rather than being scared off by the excellent standards of infrastructure apparent in David and Mark's videos, local authorities in the UK would do well to look again at the example of Bremen in our own film, Beauty and the Bike. In Bremen, levels of cycling are high (25%) despite very patchy standards of infrastructure. Here, cycle paths were first installed in the 1970's, at a time when traffic levels - and infrastructure build standards - were generally much lower than today.

LTP3s around the country really have to decide - is cycling going to continue as a bolt on to car-centric urban transport policy? Or is it time for the UK to begin the long process of de-motorising our towns?
