Embodiments of the present invention relate to a method of determining speed information, comprising receiving traffic monitoring information navigation devices (), wherein the traffic monitoring information includes identification information identifying a mobile device (), location information indicating a geographic locations () at which the identification information was received from the mobile device (), and temporal information indicating times at which the identification information was received, and determining speed information associated with the mobile device from the traffic monitoring information.

Navigation device and method

In at least one embodiment, a method is disclosed that includes determining algorithmically a a plurality of vehicle cost values for traveling a plurality of road segments in a vehicle based at least in part on vehicle cost data derived at least in part from position derivative data obtained from at least one vehicle that traveled the road segments (S); associating each of the plurality of road segments with at least one of the vehicle cost values (S); and storing the determined vehicle cost values in a memory device (S). In at least one embodiment, a method for determining a route of travel from a first location to a second location is disclosed. Other embodiments include a map database, storable on a storage medium; a device including a memory () storing a map database, a processor () and an output device (); and a device for use in a vehicle, where the device includes a GPS receiver (), a memory () and a processor ().

Methods, devices and map databases for green routing

A method and system of generating a horizon for use by an ADAS of a vehicle involving recording the historic movements of the vehicle on a road network, and using the recorded data to determine at least a most probable path that the vehicle will take at decision point of the road network.

Methods and systems for generating a horizon for use in an advanced driver assistance system (ADAS)

In a method for creating a digital representation of a transportation network location measurement data is acquired, and a plurality of maneuvers between choke points are generated from the location measurement data. The digital representation of the transportation network is then created and stored based on the plurality of maneuvers.

Methods and systems for creating digital street network database

A method of generating a horizon for use by an ADAS of a vehicle involves using historical vehicle probe data to determine the likelihood that different outgoing paths are taken at a decision point along a currently traversed road segment, and deriving a probability that each path may be taken. The probability is based on historical paths taken by vehicles at the decision point as indicated by the vehicle probe data.
