Method and apparatus for creating cost data for use in generating a route across an electronic map

A non-transitory computer readable medium including a computer program comprising computer program code means adapted to perform, when said program is run on a computer, a method for creating cost data for use in generating routes across an electronic map of navigable segments, the method comprising:

• receiving probe data from a plurality of users, the probe data comprising, for each user, movement data indicative of the movements of the user with respect to time, and physical exertion data indicative of at least one measure of physical exertion associated with the movements of the user over time;
• processing, for each of one or more navigable segments, the probe data received from a plurality of users traversing the same navigable segment, the processing comprising:
• scaling probe data received from each of the plurality of users that traversed the same navigable segment based at least in part on an ability profile for the corresponding user;
• and
• deriving, based at least in part on the scaled probe data, normalized routing cost data for the same navigable segment;
• associating the routing cost data with the one or more navigable segments of the electronic map;
• providing, to a user device, the electronic map, wherein the electronic map is configured to enable the user device to determine a suggested route based on the routing cost data associated with the one or more navigable segments and at least one of an ability profile and one or more user specified parameters.

A system for creating cost data for use in generating routes across an electronic map of navigable segments, the system comprising one or more processors, said one or more processors being arranged to:

• receive probe data from a plurality of users, the probe data comprising, for each user, movement data indicative of the movements of the user with respect to time, and physical exertion data indicative of at least one measure of physical exertion associated with the movements of the user over time;
• process, for each of one or more navigable segments, the received probe data received from a plurality of users traversing the same navigable segment, the processing comprising:
• scaling probe data received from each of the plurality of users that traversed the same navigable segment based at least in part on an ability profile for the corresponding user;
• and
• deriving, based at least in part on the scaled probe data, normalized routing cost data for the same navigable segment;
• associate the routing cost data with the one or more navigable segments of the electronic map;
• providing, to a user device, the electronic map, wherein the electronic map is configured to enable the user device to determine a suggested route based on the routing cost data associated with the one or more navigable segments and at least one of an ability profile and one or more user specified parameters.
