Where do people die on urban roads?

30 Sep

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.

Making urban roads safer for pedestrians

29 Sep

Philip Hammond has explained today that he wants us to drive faster on motorways in order to create a ‘healthy economy‘, ‘generate hundreds of millions of pounds of economic benefit‘ and ‘put Britain back in the fast lane of global economies‘. This proposal was evidently resisted by the Health Secretary and the Energy Secretary for obvious reasons and the RAC Foundation estimates that driving 10 mph faster increases fuel use and CO2 emissions by more than 20%; the AA have reported that we are actually driving more slowly now in response to increased fuel costs. Hammond says it won’t increase road casualties – others disagree. I think this whole proposal is rather unhelpful and may well back-fire on the government. However…

My main interest here is on the needs of the pedestrian and Philip Hammond also promised a big expansion of 20 mph speed limit zones in urban areas where nearly all of the 403 pedestrian road fatalities, 5,000 serious injuries and 20,000 slight pedestrian injuries occurred during 2010; 42% of all road fatalities also occurred in urban areas. We need to continually remind people of the scale of the road safety problem in our country and press for these 20 mph limits in residential areas which have proved to be very effective.

Here are a couple of maps showing the scale of our road safety problem. The first map shows the locations of all pedestrian deaths (red dots), serious injuries (purple dots) and slight injuries (blue dots) on GB roads between 2000 and 2008; other road deaths and serious injuries are shown using lighter grey dots. The boundaries are parliamentary constituencies. Click on the map to enlarge.

This second map shows all road fatalities (red), serious injuries (purple) and slight injuries (blue) for 2008 when 2,500 people died and 26,000 were seriously injured.

Since 2005 the United Nations has supported the inspiring World Remembrance Day for Road Traffic Victims which is an opportunity to reflect and remember those killed on our roads. It takes place this year on 20th November with services across the UK and all round the world. Why not ensure that a suitable remembrance service is held near where you live this year?
