In another embodiment, the system for providing road condition navigation may further include a plurality of first user terminals.
In one embodiment, the second user terminal 102 and the first user terminal 103 may be provided with a processor, a memory, a screen, a communication module, operation keys, and the like, the processor may be configured to identify and process operations of a user, the memory may be configured to store data required and generated during the processing, the screen may be configured to display content required to be displayed to the user during the processing, the communication module may be configured to establish a communication connection with other devices, and the user may operate the terminals by operating the operation keys (including physical operation keys and virtual keys). The second user terminal 102 and the first user terminal 103 support the user to download the application program required by the user to the local, in this embodiment, the first user terminal 103 is installed with a road condition navigation application program such as a map.
Based on the system, the embodiment of the invention provides a road condition navigation method, which comprises the following steps: the server 101 may receive the real-time traffic information uploaded by the second user through the second user terminal 102, and the server 101 may determine a traffic state of a first route traveled by the first user based on the real-time traffic information uploaded by the second user in real time, and may re-plan and recommend a second route to the destination of the first user, so that the first user may adjust the own travel route to the destination based on the real-time traffic information.
Referring to fig. 2, an embodiment of the present invention provides a road condition navigation method, which is applied to a server 101, and includes the following operation steps:
in step 201, receiving real-time traffic information uploaded by a second user;
in the embodiment of the present invention, the second user may report the real-time traffic information of the road segment known by the second user, such as the position where the traffic accident occurs or the congested road segment, to the server 101 through the second user terminal 102, and the server 101 records the real-time traffic information of the position where the traffic accident occurs or the congested road segment, which is uploaded by the second user, after receiving the real-time traffic information.
In step 202, determining a traffic condition of a first route based on the real-time traffic information and the first route currently driven by a first user;
in the embodiment of the present invention, a first user requests to plan a first route to a destination of the first user through a navigation application such as a map installed on a first user terminal 103, after receiving a route planning request requested by the first user, a server 101 calculates a first route to the destination of the first user for the first user and informs the first user, and the first user may then travel along the first route. Here, if the server 101 receives real-time traffic information, such as a traffic accident occurring location or a congested road segment, uploaded by a first user, the traffic accident occurring location or the congested road segment is compared with a road segment on the first route; when the position where the traffic accident occurs or the congested road section is located on the first road section, judging that the traffic condition of the first route is poor; and when the position where the traffic accident occurs or the congested road section is not on the first road section, judging that the traffic condition of the first route is good.
Recommending a second route to the first user to reach the destination based on the traffic condition in step 203;
in the embodiment of the present invention, when the traffic condition of the first route is poor, the server 101 recommends a second route to the first user to reach the destination and bypass the traffic jam or the accident occurrence location based on the current location of the first user.
Here, when the server 101 knows that there is a traffic jam on the first route currently traveled by the first user or there is an accident based on the obtained real-time traffic information, it may calculate a second route that can reach the destination of the first user again for the first user based on the obtained current location of the first user and the destination thereof, so as to bypass the accident site and the traffic jam.
In the embodiment of the present invention, before recommending a second route to the destination to the first user based on the traffic condition, the traffic condition of the first route is notified to the user, and it is suggested that the first user can travel along the recalculated second route. When the first user carries out route navigation according to the prompted second route, road navigation is carried out for the first user according to the second route after the system confirms that the first user switches to the second route for driving.
For example, when the server 101 determines that the traffic condition of the first route is poor, the first user is to be notified of the traffic condition of the first route by the first user terminal 103, and then recommended to travel by the first user along the second route that can be recalculated. Such as: "the victory road goes to the Weichai state road, and traffic accidents happen from east to west, and the Weichai state road can not pass through, and the Weichai state road suggests that you turn right 300 meters ahead, enter into the Iris flyway and detour from the east wind street". If the first user turns right according to the prompt, the system considers that the first user switches to a second route to drive, and then the system navigates the first user according to the second route; if the first user does not turn right according to the prompt but continues to go straight, the system considers that the first user does not want to switch the route and continues to navigate according to the first route; if the first user turns left, instead of turning right or going straight, the system recalculates the third route for the first user based on the first user's current location and destination, and then navigates the first user based on the third route.
The following example is given to the road condition navigation scheme with reference to a specific application scenario, as follows:
the first user plans to drive from a position A to a position B, the first user opens a map application installed on a first terminal 103 to use a navigation function of the map application, the user inputs a starting position A on a page of the route navigation function or automatically positions the map to obtain the starting position A and a destination B of the user, a background server 101 of the map application calculates a first route with the shortest route distance for the first user based on the starting position A and the destination B according to a shortest route calculation rule (here, the system calculates the shortest route for the user according to the shortest route calculation method or predicts other driving routes for the user according to the driving speed, such as a high-speed priority route and a recommended route for the user to select). Wherein the calculated meeting on the first route traveling from location a to destination B is routed to location C.
The first user drives according to the navigated first route, during which the server 101 may receive real-time traffic information, such as a congested road section or a location where an accident occurs, which is known by the second user and uploaded by the second user through the second user terminal, for example, the second user finds that a traffic accident occurs at the location C, and the second user reports the location information to the server 101 through the second user terminal 102; after receiving the location information C of the traffic accident uploaded by the second user, the server 101 acquires the current driving location of the first user from the map, determines whether the location C exists on a first route intended to be driven by the first user, if so, calculates a second route capable of avoiding the location C of the traffic accident for the user again based on the acquired current driving location of the first user and the destination B, notifies the first user that the traffic accident occurs at the location C of the first user, may cause congestion of the first route, suggests the user to drive according to the second route, and continues to perform navigation service for the first user according to the second route if the user drives the route according to the suggestion.
In summary, the server 101 may receive the real-time traffic information uploaded by the second user through the second user terminal 102, and after receiving the real-time traffic information, the server 101 may determine the traffic condition of the first route based on the real-time traffic information and the first route currently traveled by the first user, and recommend the second route to the destination of the first user based on the traffic condition of the first route. The server 101 may determine a traffic state of a first route traveled by the first user based on real-time road condition information uploaded by the second user in real time, and may re-plan and recommend a second route to the destination of the first user, so that the first user may adjust the travel route to the destination based on the real-time road condition, and avoid a route with possible traffic congestion.
The first user terminal 103 may be implemented as a mobile phone. In addition, the first user terminal 103 may also be implemented as a car navigator, and various functions of the first user terminal 103 are provided in the car navigator; at this time, the server 101 is configured to receive the real-time traffic information sent by the second user terminal 102, and then the server 101 sends the real-time traffic information to all vehicle-mounted navigators (i.e., the first user terminal 103) in the administrative district and around, and the vehicle-mounted navigator performs the aforementioned step 202 "determine the traffic condition of the first route based on the real-time traffic information and the first route currently traveled by the first user" and the aforementioned step 203 "recommend the second route to the destination to the first user based on the traffic condition".
To the extent that an explanation is added herein, this need not be written in the claims.
