Abstract

Vehicle route-planning system can acquire position signals and surrounding images from vehicle terminal apparatuses in real time. The vehicle route-planning system includes an images-analyzing module and a vehicle route-planning module. The images-analyzing module synthesizes a driving condition signal in real time, according to position signals and surrounding images. The vehicle route-planning module can merge the real-time driving condition signal and a map data to synthesize a real-time driving condition mapping data. When a vehicle terminal apparatus receives a route terminal point configuration, the vehicle route-planning module can generate an optimized vehicle-route signal corresponded to the route terminal point configuration, according to the position signal of the vehicle terminal apparatus, the route terminal point configuration and the real-time driving condition mapping data. The optimized vehicle route signal can be transmitted to the vehicle terminal apparatus receiving the route terminal point configuration.
