Road traffic navigation system and navigation route generation method

Abstract

The invention relates to a road traffic navigation system, which comprises a road traffic monitoring system, an information processing center and an intelligent terminal. The road traffic monitoring system consists of a plurality of monitors which are distributed on all road sections for monitoring instant traffic conditions of the road sections where the monitors are positioned and regularly refreshing information of the road, which is stored in the information processing center. Maps, vehicle information and traffic information of all the road sections and nodes positioned in the road traffic monitoring system are stored in the information processing center. A user inputs a navigation request on the intelligent terminal; the intelligent terminal requests the information processing center to feed back road condition information which is customized aiming at the user according to a vehicle ID of the user, generates a navigation route according to the information and displays the navigation route to the user; and after the navigation route is generated primarily, the intelligent terminal regularly refreshes the navigation route in a rolling mode so as to provide real-time effective information for travelers, help the travelers better carry out route selection, shorten travel time and make vehicles bypass the crowded road sections to avoid entering the crowded road section and avoid large-scale traffic jam.

Description

technical field [0001] The invention relates to a road traffic navigation system and a navigation route generation method, in particular to an urban road traffic navigation system and a navigation route generation method. Background technique [0002] With the popularization of automobiles, road congestion has become a problem that people gradually pay attention to. According to statistics, the gasoline and time wasted due to traffic jams in the United States cause economic losses of up to 68 billion U.S. dollars every year. The predicament seriously affected the city's operational efficiency. [0003] Today, with the ever-increasing pace of life, people pay more and more attention to the time it takes to reach their destination when driving. The shortest route obtained by the electronic map navigation system is often not able to guide users to avoid congested areas, and is not the best route in the true sense.

According to statistics, the gasoline and time wasted due to traffic jams in the United States cause economic losses of up to 68 billion U.S. dollars every year. The plight of the city has seriously affected the operational efficiency of the city

[0003] Today, with the ever-increasing pace of life, people pay more and more attention to the time it takes to reach their destination when driving. The shortest route obtained by the electronic map navigation system is often not able to guide users to avoid congested areas, and is not the best route in the true sense

[0004] Patent 200810041079 discloses a dynamic road condition information generation and navigation system, which can simulate and calculate a route plan based on real-time traffic information between the departure point and the destination, predicted traffic information, default traffic information and electronic maps at the time of departure. However, such The navigation system is based on the road conditions at the time of departure and the route selection estimated by historical experience, which is not completely consistent with the real-time road conditions during travel. It is often difficult to turn around and leave when entering such a road section without knowing it. At this time, although the navigation system will recalculate the navigation route because the deviation between the actual driving time and the estimated time exceeds the specified range, this route revision is only when the user is stuck in traffic. The remedial measures taken after congestion cannot guide users to avoid the road section before the congested section, which will waste the user's time. When a large number of vehicles drive into the congested section without knowing it, it will cause greater congestion and even affect Traffic around the road
