Abstract
The present invention provides a method for guiding traffic flow in vehicle-dense regions based on a three-dimensional traffic system, relating to a method to alleviate traffic pressure. The method includes: positioning a drone above the downstream of a vehicle-dense region; aerially photographing traffic condition information, and acquiring image data information from a captured traffic condition information image; determining traffic guidance information for a vehicle upstream to the vehicle-dense region; transmitting by the drone the determined traffic guidance information to a vehicle-mounted terminal of an upstream vehicle, transmitting by a downstream vehicle its traffic guidance information to the vehicle-mounted terminal of the upstream vehicle; weighting by the vehicle-mounted terminal of the upstream vehicle the traffic guidance information from the drone and from the downstream vehicle, and transmitting the result to a vehicle display; driving by a driver according to information displayed on the vehicle display until the vehicle leaves the vehicle-dense region. The present invention can effectively reduce the driver's frequent “start-stop” maneuver, so that the vehicle can pass the dense region slowly and smoothly.
