Abstract: A method of creating a speed estimation representative of vehicle speed along one or more road segments. In at least one embodiment, the method includes obtaining at least reference speed data from a reference source of data and second speed data from a second source of data, wherein the second source is different from the reference and the speed data is indicative of vehicle speed along the or each road segment; using the reference speed data to verify the second speed data and modifying the second speed data according to the verification; and generating an estimation of vehicle speed for the or each road segment based upon the verified second speed data.

Abstract: A method of providing a graphical indication of traffic congestion along a stretch of physical road notionally divided by a traffic information provider into one or more road segments is disclosed. The invention also covers a navigation system, portable navigation device, and or software capable of implementing such a method.

Abstract: A method of displaying navigation information and A navigation device comprising a receiver to receive traffic information, whereas the device is programmed with a map database and software that enables to display a current position of the device on a road navigation map, the device is further programmed to be able to display a status bar providing information about a planned route, whereas the user can plan a first route by inputting a first position and inputting a second position and store said first position and said second position, the user can initiate a displaying of received traffic information assigned to said first route between said stored first position and said stored second position independent from the current position, and after displaying of received traffic information assigned to said first route between said stored first position and said stored second position a second route is calculated between the current position and a destination.
