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.

Traffic speeds and congestion by region

Last month the Department for Transport published new quarterly statistics on congestion on local authority ‘A’ roads, which include most motorways and carry about 80% of all traffic in England. The chart below shows trends in average speeds (and by implication, congestion) in each region during the equivalent quarter of each year back to 2008 (click for full size).

This illustrates a few points:

  • Congestion is much higher in London than in any other region, unsurprisingly.
  • However, London is the only region where congestion did not worsen between 2008 and 2010 (as shown by lower speeds).
  • However however, speeds increased and congestion fell in every region apart from London between 2011 and 2012.

To what extent this latter trend is due to transport policies or to factors such as different weather conditions or different economic fortunes is open to speculation.

Car ownership in London continues to fall

We’ve posted before about falling car ownership in London, as measured by the number of cars per household. The latest figures from DfT show this figure continuing to fall in London, from 0.78 cars per household in 2008/09 to 0.76 in 2009/10. Meanwhile it’s up very slightly in the rest of Britain, to 1.21 cars per household. So there are roughly three cars for every four households in London, compared to nearly five in the rest of Britain.

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.
