Hi,
I’ve seen in some apps when they display in the map the bus stop (red circle with the platform letter) they also show an arrow icon pointing the direction.
I wonder how can we get this info.
Is it the direction of a straight line connecting the current stop and the end stop or it’s some info we can get from the api?
It might not be possible to just use a straight line assumption for this kind of arrow: quite often the “reserve” bus stop will be accessed via a pedestrian crossing. For example, the Bus Stop X at Stratford City bus station has awkward-looking arrows pointing to it at the bus station’s main screen.
Albert,
http://content.tfl.gov.uk/syndication-developer-guidelines-bus-stop-locations-routes.pdf, pages 5 & 6:
“heading”
Number
“Direction the bus is travelling in when it arrives at the bus-stop. This is expressed from 0° to 359°.”
Have a look at Our open data - Transport for London under “Bus stop locations and routes” and the file bus-stops-examples.csv which contains ‘Location_Easting’, ‘Location_Northing’ and ‘Heading’.
Hope this helps,
Simon
