A user records a navigation instruction for a maneuver at a junction via their navigation device. The user indicates a distance before the junction at which the maneuver should be provided. The user does this by providing an input to the navigation device when a current position is at the relevant distance while driving around. The device then determines the maneuver in a digital map to be associated with the instruction by determining the next maneuver in a calculated route the user is following. The navigation device uploads the navigation instruction and the associated maneuver and distance to a central navigation instruction database. Other users may then download and use the navigation instruction.

Methods and systems for obtaining navigation instructions

Embodiments of the present invention relate to a device including a module () which is operative in a low-power state of the device (). The module () is arranged to determine whether a traffic situation on a route has more than a predetermined affect on the route, and to cause the navigation device () to output a notification in response thereto which alerts the user of the device to the traffic situation despite the device being in the low-power state.

Navigation device and method

A method of determining data indicative of an individual driver workload is disclosed. The method involves obtaining a generic driver workload parameter, the generic driver workload data being based on data indicative of the behavior of multiple drivers when performing a maneuver at a node or traversing a set of one or more segments of an electronic map. An individual modifier representative of the behavior of an individual driver is generated and used to determine an individual driver workload parameter indicative of the workload of the individual driver when performing the maneuver at a node or traversing the one or more segments of an electronic map based on the generic driver workload data for performing the maneuver at the node or traversing the one or more segments of the electronic map.
