Locations may include modifiers to change how routes are calculated.
Using the Heading Parameter
When you specify waypoints (origin, destination, and intermediates) for a route, you can specify the direction you want the vehicle to head when it arrives at each waypoint. You can use this feature to ensures that the vehicle arrives on the same side of the road as the consumer waiting to be picked up. When you don't specify a heading, the vehicle can arrive on the wrong side of the road.
Specifying a heading for a waypoint
Heading values are whole numbers that align with the compass directions, and therefore range from zero to 359. For example, a value of 0 indicates a heading direction of due North.
Example
The following example demonstrates how to set a
heading
for a waypoint.
{ "latLng": { "latitude":37.419734, "longitude":-122.0827784 }, "heading": 127 }
Using the Side of Road Parameter
When specifying a waypoint, you can request that the route go through whichever
side of the road the waypoint is biased towards by using the side_of_road
parameter.
Example
The following example demonstrates how to set
side_of_road
for a waypoint.
"location": { "latLng": { "latitude":37.419734, "longitude":-122.0827784 }, } "sideOfRoad": true
