example

[0074] Here is an example of an embodiment where the user uses the touch screen to check cameras on alternate possible routes. FIG. 1 shows a map of a travel area displayed on a PND screen 10 . Note that the location of the vehicle with the PND installed is indicated, as well as the requested destination and the approximate location of the two static traffic cameras. The user touches the camera icon displayed on the screen to select camera 1 . The PND downloads the appropriate image from the proxy server. FIG. 2 shows an image from the camera 1 displayed on the PND screen 20 . According to the direction of the arrow near the camera 1 in FIG. 1 , the camera 1 is pointing in the opposite direction to the possible route of the user through the camera 1 . This example is in the United Kingdom, where traffic drives on the left. Thus, the user's likely route is suffering from congestion because the image shows congestion on the side of the road where traffic is traveling in the ...

Abstract

A navigation device displays a route superimposed on a road map, together with one or more symbols each indicating a location for which audio or visual traffic information exists, each symbol being selectable to play back the audio or visual information. Visual traffic information can be from a fixed traffic camera; a driver can hence rapidly view a video feed or still image from a traffic camera to allow him to assess the traffic conditions.

Description

technical field [0001] The invention relates to a navigation device for displaying traffic information. Background technique [0002] Technological advancements and the increasing pressure of congested road environments have spurred the development and adoption of personal navigation devices (PNDs). The acronym PND is sometimes used to mean "portable navigation device", but will be given a broader definition in this A personal navigation device of any kind that is fixed in a car). A PND may be a dedicated navigation device (e.g., a device whose primary function is navigation) or may have multiple other applications (e.g., a media player), or may have a primary function other than navigation (e.g., it may be a mobile phone ). PNDs are primarily (but not exclusively) used in automobiles and other motor vehicles. The PND incorporates a map database containing road information and points of interest. It typically includes software that allows the user to enter a destination...
