how is this map created?

The above website has a animated google map.
I have looked at the source code and can understand the basic co-ordinates used, however the route function seems to be coded

As you can see its coded like this:

How can I create a similar animated map for a walking tour route?
It seems the code to create the route, ie, the blue lined route is in some special code.,

There must be a way to create a similar kind of map but cant understand how, anyone any ideas?
I did email the website creator but they will not reply.

thanks for the link but its not exactly the same as the original link
i gave,.
its how to create the specific route as shown in the blue. It does not
follow a normal google map direction, its a bus route so passes along
non direct streets. In the source code i can understand the co-
ordinate part its the creating the specific route that seems to be
encrypted/coded as sjown but the gobblegook as shown above.
