Accurate Speed Limits In Real Time

Hi

Does your api use heading and elevation as allowed parameters to be sent in addition to lat /long in order to determine the speed zone of a point on a given road ??

How does the system account for different speed zones on parallel roads or entry / exit ramps on / off a freeway for example, so that the car driving in a lane closes to the parallel road with a different speed limit to the road being driven on does not have the speed limit of the parallel road being incorrectly indicated as the speed limit for the road being driven on.
