Dear All

I hope I've come to the right place to ask this question.

I was commenting with a colleague recently how she (living in Sevenoaks)
takes a similar amount of time as me (in Raynes Park) to get into work
(we're based in Monument).

It made me wonder if anyone has re-designed a London travel map in terms of
time frame of reference - i.e. shortest time taken to get to a major London
station (e.g. Waterloo, Victoria, London Bridge, Liverpool Street etc.)
from around the south-east?

Just interested from a commuting viewpoint.

Regards
Richard

There is software available to companies involved in transport planning
which can plot "isochrones" (contours of time) of public transport
journey time to a specific point in London.

Unfortunately I can't immediately see any available on the internet.

Thanks - if you are able to find anything then please report back - it's
something I'd often wondered about and would have thought something would
have been available !

Many thanks

Unfortunately it's not openly available as those companies use the
software to provide information to clients, e.g. when assessing an
office relocation scheme, they can provide the client with maps showing
which areas become closer temporally to the new location, and which
become further away, plotting the change in journey time as a set of
isochrones.

It's pretty interesting stuff; I did have a paper version of one, but
I'm not sure where I put it, otherwise I'd scan it in to show you.

You get strange bubbles in areas where express trains stop. Slough and
Reading would be in the same isochrone for places in zone 1 for example,
but Maidenhead and Twyford would be "higher". Of course time of day and
mode of travel makes a difference too.

When I joined my last company in 1988 the personnel dept had a
printed map for London's public transport, mostly oriented to trains
coming in from outer suburbia, as I recall. The map was ancient
then, disintegrating, and held together with sellotape. I don't
remember who published it. As a child, I remember seeing pre WW II
atlases, old then, with maps of Britain, coloured like contour maps,
showing time to reach London by train.

I think the newer versions of Autoroute do isochrones for cars, and,
of
course, bikes.

There's something funny, though, about the numbers Autoroute produces
if you send it out on a bike at 10 mph.

Every now and again I see "accessibility maps" put out by London's
planning or transport people. I think they credit it to a program
they have called PTAL, or some such. I wonder if you could demand a
copy of the program under the Freedom of Information Act.

PTAL is a scoring system from 1 (or perhaps zero?) to 6, with 6 being
the highest level of public transport accessibility. The southern
portion of the King's Cross development (developers: Argent) has a PTAL
score of 6, as by the time it is built, it will probably have the best
public transport accessibility in the entire country.

PTAL is not a program, it's an acronym.

"public transport accessibility level"

Ken's bunch are quite keen on it - basing parkign standards for development
on PTAL etc. See the London Plan, e.g. p.48

I think it can't be done on a flat map without rearranging the order of
stations on each line.

Thus your Raynes Park (23' am peak) will have to be shown as further
out than Surbiton (18') as will Wimbledon (19').

Commuters from West Byfleet were complaining that with the new
timetable they had only stopping trains in the morning peak (40') but
they do have a fast return service (26'). So West Byfleet must be shown
as further out than Wokng (26' & 23') and possibly as far out as
Farnborough (36' & 39').

Best of luck to anyone trying to generate such a map.

You do it like a weather chart or OS map with contours. The contours
represent the points of equal time and yes some places further out will
have less travel minutes.
