Caroline Russell from Islington Living Streets left a comment on my last post highlighting the fact that people get killed and seriously injured on artery roads, not on the residential roads where 20 mph speed limits are to be promoted by the government. Personally I think 20 mph limit area for residential roads are great and reduce the level of intimidation or pedestrians, I live in one. I am however also aware that people do indeed get killed and seriously injured on the arterial roads. Here is a map showing all killed and seriously injured in the period 2000-2008 inclusive for part of Islington/Hackney showing that injuries and deaths do indeed occur on arterial roads.
Killed and Seriously injured – Islington and Hackney. 2000-2008
Here is a map for a larger area – notice how the arterial road network is visible even at this scale solely from the location of traffic casualties. click to open the image at full resolution.
Killed and Seriously injured – North London. 2000-2008
And here is one for most of north London. Again the arterial road network can be identified very easily. Click to open the image at full resolution.
Killed and seriously injured – Greater London. 2000-2008
