Abstract

Mapping information is presented to a user. Information about dynamic road conditions is integrated into static mapping data to generate dynamic mapping data. The dynamic mapping data is displayed to a user via a display. For example, the dynamic road conditions are obtained from a detector that detects dynamic road conditions. The detector is, for example, a safety warning system detector. Alternatively, the detector may be some other type of detecting device such as a radar detector. The information about dynamic road conditions can also be obtained from a wireless service that accumulates information about dynamic road conditions. Any information about dynamic road conditions obtained from a detector that detects dynamic road conditions can be forwarded to the wireless service to make the information available to other users with access to the wireless service. Positioning information can be used to display to the user a current position relative to the dynamic mapping data. For example the positioning information is obtained from a global positioning system (GPS) or from some other positioning methodology. In order to generate an optimal route for travel between two locations, information about dynamic road conditions can be integrated with the static mapping data to assure a best current route is determined.
