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 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.

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.

New TfL report about onwards travel from Central London termini

Just noticed that TfL have recently published a report about onwards travel from the main Central London rail termini, which you can find here. It looks at who uses the termini, where they are going (in terms of location and trip purpose) and how they get there. Here’s a chart of onwards distance travelled by mode:

One of the more interesting findings is the make-up of the group of people that usually cycle their onwards journey: “Cycling is dominated by a particular demographic. Eighty two per cent of cycle journeys are made by men and 60 per cent of cyclists are aged between 25 and 44”. The new Cycle Hire scheme doesn’t seem to have changed this much.

TfL report on London Travel Demand Survey

Not sure when it came out, but TfL have published a report (link here) analysing data from the 2007-10 dataset of their London Travel Demand Survey. It’s full of interesting stuff about how, when and where Londoners travel, the chart below being just one example.

Casualties from collisions with goods vehicles, by mode

The 2010 London Freight Data Report (pdf), prepared for TfL by a team from the University of Westminster, has a wealth of information about goods vehicle traffic in London, some of it already already analysed over at Cycle of Futility.

The chart below is based on table 4.4 from the report, and shows the number of fatal and serious casualties resulting from collisions in which goods vehicles were involved in London, by mode of travel, for 1994-98 (averaged) and for 2008, the latest year available.

The (relatively) good news is that the number of car/taxi occupants, pedestrians, goods vehicles occupants and bus/coach occupants killed or seriously injured in collisions with goods vehicles has fallen sharply between 1994-98 and 2008. The bad news is that the trend for motorcyclists is almost and the number of cyclists killed or seriously injured (KSI) in collisions with goods vehicles has actually risen over the period, so that cyclists now account for 19% of goods vehicle-related KSIs, up from 8% in the mid 1990s.

Pedestrian Countdown Trial: Unpublished Appendices

The Pedestrian Countdown trial was conducted in 2010 for Transport for London by consultancy Transport Research Laboratory (TRL).

The “blackout” phase used at pedestrian junctions where neither the green nor red man is showing was replaced by a “countdown” phase, where a timer counts down the seconds that pedestrians have to finish crossing the road.

A number of other changes were also made to signal timings, for both road traffic and pedestrians. The following is a summary:

Pedestrian phases



Green man




Pedestrian red


Total pedestrian time


Road traffic phases




– “Pedestrian red” is the grace period at the end of the pedestrian phase where the red man appears but road traffic signals are still red.

– “Blackout” is the period for pedestrians after the green man where there is no green or red man showing, and is the phase wholly replaced with Countdown.

Changes in time

We have composed the following graphs with data from the TRL Technical Appendices (see below), which show average changes to both pedestrians and road traffic timings across all sites:

Changes to pedestrian time

Changes to road traffic time

N.B. “After” in the pedestrian phase is the “After 1” trial, immediately after PcATS is installed. The appendices do not contain the figures for the tweaked “After 2” trial, three months later, though we are told the green time is the same. We can infer from the decreased green and increased red time that road traffic faces in the After 2 trial (compared to After 1) that either blackout/countdown or pedestrian red time (or both) is slightly increased.


Transport for London published a summary report following the trial:

Pedestrian Countdown Project Report

It contains several unpublished appendices which we have obtained through Freedom of Information request and publish here for your perusal.

Exposure to transport noise in London

Among the wealth of information in the the GLA’s new State of the Environment Report are two tables (p. 57) showing estimates of the number of dwellings and people in London exposed to noise from roads or railways above particular noise thresholds. We used this data to produce the chart below.

Trend in London cyclist casualties by severity

Transport for London’s factsheets and reports on collisions and casualties in London can be found here. General reports covering all modes are published annually (first as factsheets then in more detailed reports), while topic-specific factsheets, for example on pedestrians or cyclists only, are less frequent.

The latest factsheet on cyclist casualties was published in November 2010 and reported on casualties in 2009, with breakdowns by borough, age, gender etc. It also includes a table summarising the trend in cycle casualties in London as a whole since 1986. We have extracted the data from this table and added 2010 data from the most recent all-modes factsheet. The chart below shows the trend, and you can download the resulting table in csv from this link.
