  2. It's a bit difficult to get much from this. For a start, absolute
    numbers are not given, nor the duration of counting. A 100% decline would
    be improbable unless it's from 1 to 0. But you would expect some increases
    of more than 100%.

    FWIW, my spot counts of parked cycles across Ealing borough, 2003-2009,
    suggest flat cycling levels. The moving counts were also flat up to 2008
    but may have ticked up in 2009. Maybe our efforts are preventing decline
    rather than creating growth.

    I would take from the map that the best increases are in areas within
    cycle commuting distance of the City - there's a lot of red in the north
    as well as the west.

    The outer boroughs need local cycling, especially to schools and stations,
    which requires:
    - reduced perception of danger
    - reduced cycle theft (especially at stations)
    - better cycle permeability
    ..... and possibly some impediment to car travel, since cycling tends to
    have less of a speed advantage over the car in outer London.

  3. may just be the type of roads they picked. for example looks like they
    measured at sunbury cross which as a bike there are faster ways if one
    was going from kingston to staines. mainly as the A308 has a lot more
    lights where the back roads by bike at least are a lot faster inspite of
    a mile or so longer there are less lights etc.

  4. Can you tell us where the data came from please. The only two data
    sources I know of are

    1. The mechanical counters on TfL's TLRN (ie trunk) roads, which is
    what TfL uses for the counts in all their press releases.

    2. The data on the DfT's web site, which quite likely is made up by
    some bored census taker There's data from 96 sites in Barnet, for
    example, and sometimes it's possible to guess, by looking at the
    figures, how they were fabricated.

    However, the sites on the map don't look to me like either of those
    sources

  6. Ah, thanks Tom for your answer (see below) It looks as if neither of
    my guesses were correct. The data seems to be from the counts taken
    by the DfT to see how many miles per year there are of each kind of
    traffic in Britain

    The company that made the pretty pictures looks interesting.
