1. A computer-implemented method of profiling a driver comprising:
- obtaining, by a position sensor mounted on a vehicle, data representing motion of the vehicle;
generating a network of links from a road map;
generating, for a link of the network of links, one or more link indexes, at least one link index being associated with a feature of the link that influences a behaviour of the driver of the vehicle travelling along the link;
identifying, by a processor, events in the data representing motion of the vehicle, the events including acceleration events and braking events characterised by a speed at which the vehicle was travelling when respective event occurred;
selecting, by the processor, one or more of the events based on a profile index associated with the respective event and on at least one attribute derived from the respective event, the profile index relating to the link on which the vehicle was travelling at a point during the respective event, wherein the profile index relating to the link is derived at least from the one or more of the link indexes relating to one or more features of the link that influence a behaviour of the driver of the vehicle travelling along the link;
determining, by the processor, a driver profile from the one or more selected events;
characterising, by the processor, the driving behaviour of the driver on a basis of the driver profile; and
providing an output interface comprising a display of an overall driver score presented in conjunction with one or more sub-scores that provide a measure of the characterised driving behaviour of the driver.

Abstract
A computer-implemented method of profiling a driver comprises: identifying events in data representing motion of a vehicle; for the events, associating an event with a profile index relating at least to a link on which the vehicle was travelling when the respective event occurred; sorting the events into groups, each group corresponding to a different profile index; determining a driver profile from the events; and characterizing the driving behavior of the driver on the basis of the driver profile.

19. A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause the processor to perform operations comprising:
-
generating a network of links from a road map; generating, for a link of the network of links, one or more link indexes, at least one link index being associated with a feature of the link that influences a behaviour of a driver of a vehicle travelling along the link; identifying events in data obtained by a position sensor mounted on the vehicle, representing motion of the vehicle, the events including acceleration events or braking events characterised by a speed at which the vehicle was travelling when respective event occurred; selecting one or more of the events based on a profile index associated with the respective event and on at least one attribute derived from the respective event, the profile index relating to the link on which the vehicle was travelling at a point during the respective event, wherein the profile index relating to the link is derived at least from one or more of the link indexes relating to one or more features of the link that influence the behaviour of the driver of the vehicle travelling along the link; determining a driver profile from the one or more selected events; characterising the driving behaviour of the driver on a basis of the driver profile; and providing an output interface comprising a display of an overall driver score presented in conjunction with one or more sub-scores that provide a measure of the characterised driving behaviour of the driver.
