  • Speed profile dictionary
    Patent number: 8954278
    Abstract: A speed profile dictionary and associated lookup tables are disclosed. A set of distinct speed profiles is defined using a statistical analysis routine. Preferably, the statistical analysis routine uses clustering. The speed profiles are then matched to location codes identifying physical locations on a road network and days of the week. Applications using historic traffic data may use the speed profile dictionary and one or more lookup tables instead of a complete historic traffic database, thereby reducing the amount of memory needed to store historic traffic data.
    Type: Grant
    Filed: February 6, 2013
    Date of Patent: February 10, 2015
    Assignee: HERE Global B.V.
