I'm bored and am playing with having a dynamic display of bus arrival times from Point 1 to Point 2.
I live in Sydney and there is a page which I can use to get the times but it has me curious.
This link to get times (example)
(Follow the red line. give or take.)
This is the flow:
But it doesn't work as expected.

This is what I get as output:
Journey 1 Leg 1 stops: Frederick St at Banks St, Ashfield, Frederick St at Albert Pde, Ashfield
Journey 1 Leg 2 stops: Frederick St at Albert Pde, Ashfield, Frederick St before Elizabeth St, Ashfield, Elizabeth St before Alt St, Ashfield, Elizabeth St at Bland St, Ashfield, Ashfield Station, Brown St, Stand C, Ashfield
Journey 1 Leg 3 stops: Ashfield Station, Platform 5, Ashfield, Croydon Station, Platform 5, Croydon, Burwood Station, Platform 6, Burwood
Journey 1 Leg 4 stops: Burwood Station, Burwood Rd, Stand E, Burwood, Westfield Burwood, Victoria St, Burwood, Victoria St at Shaftesbury Rd, Burwood, Victoria St at Lucas Rd, Burwood, Burwood Girls High School, Queen St, Croydon, Queen St opp Webb St, Croydon, Blair Park, Queen St, Croydon, Lang St after Queen St, Croydon, Church St opp Centenary Park, Croydon, Church St at Croydon Rd, Croydon, Croydon Rd at Dalmar St, Croydon, Great North Rd opp Harrabrook Ave, Five Dock, Great North Rd at Longview St, Five Dock, Great North Rd opp Club Five Dock RSL, Five Dock
And then it goes on to Journey 2, so I won't include it for now.
But I don't get what's happening.
It seems to me that it thinks I walk from one side of the road to the other and catch the bus going in the opposite direction and all this other stuff which complicates what I'm wanting to get/do.
The API_KEY is removed. Sorry. But I'm sure you understand.
Anyone near by mind having a look and help me understand how to get it working?
I have a few bus routes / train time tables I want to see dynamically see their times on a GUI.
