Data about transport in London!

Complaints data from TfL

As covered here by London Reconnections, TfL have released some figures (at the back of this report by the Commissioner to the TfL Board) on complaints received from the public about various transport services in London during the financial year 2011/12. The summary table, reproduced below, shows that complaints levels per 100,000 journeys made were much higher on the Dial-a-Ride and Cycle Hire services than on the mainstream services.

One thing that might be of note is that according to the figures for bus complaints, there were around 4,700 complaints made in 2011/12 about ‘poor or dangerous driving’ by London bus drivers.

Road casualties in London in 2011

In late June TfL published a factsheet on road casualties in 2011, which you can find alongside previous versions here. There were 29,257 casualties recorded by the police in 2011 (inevitably an under-estimate, since many injuries don’t get reported, particularly the less serious ones). Of these, 159 were fatalities, 2,646 were serious injuries, and 26,452 were slight injuries.

The number of people killed or seriously injured (KSI) fell 3% from 2010 to the lowest number since 1986 (the earliest year of police reporting at Greater London level). But there were huge differences in trend for different categories of road user: while the number of car occupant KSIs fell by 31% and the number of bus or coach occupants by 12%, the number of cycling KSIs increased by 22% and the number of pedestrian KSIs by 7%.

Of course, these divergent trends are partly due to different trends in traffic for each mode, with car traffic generally falling and cycling rising in recent years. But it’s very unlikely that car traffic fell by 31% or that cycling rose by 22%, so it is highly probable that the car casualty rate fell and the cycle casualty rate rose. We should get more evidence on casualty rates when DfT update this table and others in a month or so.

It is also worth noting that DfT publish very detailed data for every single recorded casualty recorded on data.gov.uk. The data is at case level so you can analyse it any way you like, but be warned that the data is quite complex (you may need to match vehicle records with casualty records, for example) so it might take some time to understand.

London Overground usage stats

In case you missed it, here’s a superb analysis by London Reconnections of a recent TfL report on the current and future usage of the London Overground.

Updated: trend in cycling flows on TLRN

We have posted previously about TfL’s statistics showing the trend in cycle flows measured on their network of main roads in London. Data for the second quarter of 2011/12 is now available and the charts below (and accompanying data) have been updated accordingly.

It’s important to note, though, that this is just one way of measuring trends in cycling in London, and probably not the best.

Parking spaces in London

TfL have made available (through their ‘Romulus‘ site) two studies of the number of parking spaces in London, the first carried out in 1999 and the second in 2004/05. You can find them by expanding the ‘Reports’ section of the left-hand menu, but be warned, they’re both big files (56mb in the case of the first one!).

The most interesting bit is probably the impact of the congestion charge on parking availability in Central London, as reported in the second study:

  • In central London there was a reduction of 45% in the number of parking spaces for employees at workplaces, compared with 1999/2000. With the introduction of congestion charging in 2003 there was less incentive for employees to drive to work in central London, and there were fewer small car parks available for employee parking.
  • There was also a 10% reduction in spaces available to the general public in central London car parks. The overall reduction in central London car park spaces (excluding those in residential car parks) was 24%. By contrast there were increases in available car park spaces in inner and outer London, outside the central area. In inner London there was an increase of 23% and in outer London an increase of 30%.
  • There was a reduction in on-street parking spaces other than at meters and pay-and-display areas. In central London there were 27% fewer spaces on single-yellow or single-red lines, which normally allow parking in the late evening and at night. In inner and outer London there were 9% fewer unrestricted on-street spaces.

Traffic casualties in London since 1901

TfL’s most recent report on traffic casualties shows that 126 people died in collisions on London’s roads in 2010. While this figure represents a terrible loss of life, one which can and should be reduced, it is also – as TfL point out – the first time the number of road fatalities has fallen below 150 since their records began in the 1970s.

It is in fact possible to go further back in history then that. Statistics for 1901 onwards were collected by the London County Council and then the Greater London Council, first covering the Metropolitan Police District and then (from the mid 1960s) the Greater London area. Fortunately these two geographies match up fairly well – the Metropolitan Police District is larger than the Greater London area, but until around the mid 60s its outer reaches were sparsely populated enough to make little difference. Using LCC and GLC statistical reports found in the libraries of the London School of Economics and the Greater London Authority, we reconstructed trends of fatalities and total casualties (i.e. including ‘serious’ and ‘slight’ injuries) in London between 1901 and 2010, shown in the two charts below.

Some clear overall patterns emerge. First, each world war resulted in a large fall below trend in both fatalities and total casualties. Taking the effect of the wars into account, the basic trend in terms of fatalities seems to be an increase to a peak of around 1,400 a year in the early 1930s, followed by a long decline that continues to this day, with the 2010 figure of 126 deaths the lowest in the entire record. Total casualties peaked much later, in the early 1960s at 70-80,000 a year, and have fallen proportionately less to around 30,000 a year.

The chart below, derived from the two above, confirms that fatalities have fallen as a share of total casualties over time, though again with notable breaks from trend at the time of the two world wars. The overall downwards trend is presumably due to improvements in emergency care and overall health over time, with the ‘blips’ during the wars probably due to a combination of factors such as blackouts and a shortage of medical care.

You can download the data for these charts in csv format here. In a future post we’ll look at the long-run trend in cyclist casualties.
