mysociety.org has an interesting article about travel-time maps:
using buses, trains and other forms of public transport. But what if you don’t
yet know what journey you want to make? How can maps help then?
This may seem a strange question to ask, but it is one we all face in
several situations:
- Where would I like to work?
- Where would I like to live?
- Where would I like to go on holiday?
These are much more complicated questions than those about individual
journeys, but one thing they all have in common is transport: can I get to and
from the places I’m considering quickly and easily?
The maps on this page show one way of answering that question. Using colours
and contour lines they show how long it takes to travel between one particular
place and every other place in the area, using public transport. They also show
the areas from which no such journey is possible, because the services are not
good enough.
