Disclosed herein is a method of route planning for global positioning system (GPS) based navigation systems. The method identifies route segments used in a GPS based navigation system and records an actual historical time of travel for at least one route segment traveled by users of the GPS based navigation system travel. The actual historical time of travel comprises the amount of time taken by a user of the GPS based navigation system to go from a beginning of the route segment to an end of the route segment. With embodiments herein, the day and time that the route segment was recorded is also noted. Then, the actual historical time of travel and the day and time for the route segment can be stored in a database. This information can be stored for a single-user or can be combined from a plurality users of the GPS based navigation systems.
