Real-time Guidance Method for Car Navigation

Abstract

The invention discloses a real-time guidance method for bus taking navigation and belongs to the technical field of intelligent traffic. The method comprises the following steps: determining an origin, a destination and departing time; carrying out path planning according to the coordinates of the origin and the destination, and obtaining the time cost of each road section in the path planning according to the departing time and a path planning result in combination with dynamic traffic data; correcting the time cost of each road section according to the actual departing time and the current position of a user and utilizing characters, voice and / or graphical representations to carry out real-time guidance at each road section. On the basis of providing the character and map demonstration of the path planning result, the real-time guidance method can further provide the progress bar of journey stages and expected time for arriving at each stage point, and can also provide a whole-journey real-time guidance function. The real-time guidance method has the advantages of simple and visual journey demonstration, timely and accurate prompt, and safety and convenience in use. The use convenience of passengers in navigation is greatly improved, and the occurrence of accidents is reduced when navigation equipment is used during motion.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a real-time guidance method for car navigation. Background technique [0002] With the rise of smart terminals, navigation software based on smart terminals has emerged one after another. The software function has developed from the original single driving route planning to today's multi-route planning for driving, riding, and walking, which greatly facilitates people's travel. [0003] The travel route planning function provided by the current navigation software plans the travel route according to the departure and destination information set by the user, provides users with walking and travel route information, provides detailed route display on the map, and The section and the bus section are distinguished to help people better understand the bus route information. The result of intelligent route planning frees people from the trouble of querying paper map...
