Hi,

Here let me clarify , I have no intentions to peep in to or any evil intention towards tfls database and other related information.

But , ofcourse Millions of users are greatly beniftted the way it serves the information. http://journeyplanner.tfl.gov.uk/

So , If we want to create some site like tfl, journeyplanner , what are the basic things we need to keep in mind.

• Which Architecture We should use?

• Can We create this website using ASP.NET(Should be able to)?

• Is TFL integrating it's website with google maps or any other GPS

Edit:

While you enter the Zip/Pin code or Station name , it creates a map automatically from source to destination and calcculates the distance also.

My Question here is , How do they calculate the distance , do they keep help of Maps or GPS or they created there own webservic?
