Here Maps: Give Directions To Correct Side Of The Street

Occasionally when calculating a route it seems the vehicle ends being directed to the wrong side of the street. I realize we can specify pass through waypoints before the final des

Solution 1:

You can use NavigationWaypointParameter with LinkPositions to set a direction you want to drive through a certain waypoint. For example:

https://route.api.here.com/routing/7.2/calculateroute.json?
app_code={app_code}
&app_id={app_id}
&mode=fastest;car
&waypoint0=link!-22020941
&waypoint1=link!-948669856

This should give you the route you are looking for, with the bus heading towards the south-east with the destination on its right.

You can change the direction of the link traversal by changing it's prefix. For example, changing -948669856 to +948669856 gives you the original, shorter route, with the bus heading north-west and the destination on the left side of the road.

Note that you can get the link ids through reverse geocoding using the Geocoder API. The link id is the <ReferenceID> under <MapReference> in the <Result>.
