Method of Transmitting a Traffic Event Report for a Personal Navigation Device

A method of transmitting a traffic event report for a traffic event from a personal navigation device comprising processing circuits, positioning circuits, memory circuits, an input interface, a display, and networking circuits, the method comprising:

• the positioning circuits determining a position of the personal navigation device;
• the processing circuits calculating a speed of the personal navigation device according to the position;
• the processing circuits determining a street the personal navigation device is traveling on according to the position;
• the processing circuits calculating a difference of a speed limit of the street and the speed of the personal navigation device;
• the processing circuits displaying a traffic event report dialog in the display upon detection of the difference being greater than a predetermined threshold;
• the input interface receiving traffic event data through user input into the traffic event report dialog;
• and
• the networking circuits sending the traffic event report comprising the traffic event data to the server.
