A great new mapping system has been created that will show you everywhere within 30minutes trave ltime of a postcode. Great for working out the most feasible places to live for a given work location or vice versa – it also throws up comibnations of public transport you might not have thought about:

The map has taken over four years in development using the free open source data set the National Public Transport Data Repository and assuming sensible journeys combining public transport.

I’ve had a look and found it fascinating.
