Hi all

I have developed a facility which allows you to find out the best
routes between two London Underground stations, try searching for it at
http://public.ok2life.com/tube/routes. The routes found are colour
coded to indicate line changes and National Rail stations where
available. There is also integrated Google Maps to show you the
surrounding area of each station along the paths found.

Let me know if you have any suggestion/comment for improvement.

An interesting idea. I tried Warren Street to Euston Square . The
fastest route between these two is on foot, but the planner suggested
three routes - one from WS to KCSP (Victoria line) then Circle to
Euston Sq. That one is vaguely sensible.

The others routes were Warren Street to Victoria, then clockwise on the
circle to ES, or northern line to Embankment, then clockwise to ES.
Can I assume that where a journey can be done with only one change it
will go for that even if it is much longer than a journey involving two
or more changes?

Hi Simon

This is correct. The route finder is optimised for the least number of
stops. It makes the assumption that we do not like changing, as it
involves walking between platforms. Sometimes this gives you the
optimal route, sometimes it does not. This is why I offer you the top
three routes to choose from. However, the system at the moment does not
have the knowledge about the short walk between Warren Street and
Euston Square, or Lancaster Gate to Paddington, or Wimbledon to South
Wimbledon etc.

I am working on it ... :-)
