Abstract

A mobile computing device can determine a first waypoint distance that indicates a distance from the device's location within which a first waypoint of a route cannot be located. This distance can be sent to a server as part of a map data request. The distance can be based on a device velocity, a request latency time, an instruction intake time and an instruction reaction time. The request latency time represents the delay from sending a request to receiving route information in response. The instruction intake time represents the time it takes for a user to read or listen to a first waypoint instruction. The instruction reaction time represents the time it takes a user to react to a first waypoint instruction. Route information contains information identifying a first waypoint that is further away from the device position supplied with the request than the first waypoint distance.
