If Blackfriars had been modelled using the Danish system, though, I think the end product would have looked very different indeed. In fact, I'd go one step further and say, not only did Transport for London fail to seriously integrate safer cycling into its new junction, it may - by encouraging motor traffic at the expense of cycle traffic - be charging London taxpayers an extra £0.30 per kilometre travelled over the Bridge. That's an awful lot of taxpayer money being wasted.
To be fair, I'm stretching the facts slightly by assuming the average additional 'cost to society' of each urban motor vehicle journey in the Danish model and applying it to each motor journey over Blackfriars Bridge. But I think the point stands: Blackfriars is emblematic of the fact that our transport officials are spending hundreds of millons to make our city centre road network more efficient for motor traffic. But this comes at a significant cost to all of us and it's a cost that we shouldn't have to pay for. Each urban motor vehicle journey costs society as a whole much more than a bicycle journey, just as the Danes say it does, because of increased pollution, road deaths and injuries, time wasted in congestion and so on.
I think it's time to change the model so that the true costs and benefits of the different modes of transport are calculated on a level playing field. London would not only start to look and feel very different if that happened, it would also have a more efficient transport network that works better for all of us and costs taxpayers much less than the current system.
The Mayor wants London to get back to business. Maybe he could start by looking at the way he allocates his road budget and adopt a cost/benefit model more like the Danish version.
