The navigation system comprises a monitoring device which is at each intersection and is used for capturing the pass video and/or image of a vehicle at the intersection and sending the pass video and/or image through a wireless transmitting module, and a vehicle-borne navigation device which plans a travel route in advance and receives the pass video and/or image of the (n+1)th intersection in the travel route to be viewed by a driver when the vehicle which is configured with the vehicle-borne navigation device is about to travel to the nth intersection of the travel route. The vehicle-borne navigation device is internally provided with a voice identification sub system. The navigation system of the invention is applied to judge the pass ability of a road intuitively, the path planning is realized, the real-time performance is good, and the traffic condition is more intuitive.
