Abstract

A real-time navigation electronic device based on determining current traffic rule information includes a positioning unit, a user interface, an information detecting-and-generating unit and a processing unit. The information detecting-and-generating unit detects and generates information for determining real-time traffic rule. The processing unit generates a navigation route according to the destination and the present position. The processing unit receives the information for determining real-time traffic rule. The processing unit determines if the information for determining real-time traffic rule conflicts with the navigation route or makes the navigation route not the best route. The processing unit re-generates the navigation route according to the destination, the present position and the information for determining real-time traffic rule when the information for determining real-time traffic rule conflicts with the navigation route or makes the navigation route not the best route. The processing unit outputs the navigation route.
