Method for updating speed limit of e.g. car in section of transport network of digital map, involves inputting vehicle speed at section by driver, and determining new actual speed limit in section based on vehicle speed

摘要

The method involves determining and evaluating actual speed of objects i.e. vehicles, which move in a section. The actual speed is compared with current speed. A new actual speed limit in the section is determined when a compared result deviates from the actual speed about a fixed, predetermined speed difference value. Vehicle speed at the section is input by a driver during moving the vehicles along the section. Another new actual speed limit in the section is determined with respect to the vehicle speed.
