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.
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.
