To further illustrate the technical means and effects of the present invention for achieving the predetermined objects, the following detailed description of the embodiments, structures, features and effects of the real-time traffic navigation method and system according to the present invention will be made with reference to the accompanying drawings and the preferred embodiments.
The foregoing and other technical and scientific aspects, features and advantages of the present invention will be apparent from the following detailed description of preferred embodiments, which is to be read in connection with the accompanying drawings. While the present invention has been described in connection with the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but is intended to cover various modifications, equivalent arrangements, and specific embodiments thereof.
First embodiment
Fig. 1 is a flowchart illustrating steps of a real-time traffic navigation method according to a first embodiment of the present invention. Referring to fig. 1, the method for navigating the real-time road condition in the embodiment may include the following steps 101-104.
In this step, the current position information of the vehicle, such as the position information of the longitude and latitude of the vehicle, can be obtained in real time through the vehicle-mounted navigation system, the destination information of the vehicle (such as the position information of the longitude and latitude) input by the driver can be received, and then the initial navigation route from the current position to the destination of the vehicle can be obtained according to the current position information of the vehicle, the destination information and the pre-stored electronic map data. The initial navigation route is a complete route from a starting place to a destination, and may include a plurality of road segments, and a driving road between every two adjacent traffic light intersections is a road segment.
The electronic map data may be pre-stored in the car navigation system, and may include a link parameter, where the link parameter may include at least one of a longitude, a latitude, an intersection position, an entrance position, and the like of a link. The drivable-in place may include at least one of a parking lot, a gas station, a residential area, and the like, which are not public road areas. The road segment parameters may further include at least one of street, roadway, building, etc. parameters of the road segment.
In this step, in the process that the vehicle travels along the current navigation route, the vehicle-mounted navigation system may obtain road conditions of the navigation route in real time, for example, whether a road section has road conditions such as congestion or not, if it is known that a congestion condition occurs in a road section ahead, it is determined whether there is a drivable-in place in the current road section, such as a parking lot, a gas station, and a residential area, where at least one exit and one entrance are not on the same road section, according to the electronic map data, if there is a drivable-in place in the current road section, such as a parking lot, a gas station, and a residential area, where at least one exit and one entrance are not on the same road section, it is determined that there is a drivable-in place in the current road section, and if there is no drivable-in place in the current road section, such as a parking lot.
In this step, the parking lot monitoring device, for example, a camera, may monitor whether the inside of the drivable-in place is congested, and provide the detected congestion condition inside the drivable-in place for the parking lot cloud for storage, so that the vehicle-mounted navigation system may determine whether there is a drivable-in place without an internal congestion condition by obtaining the congestion condition of the drivable-in place stored by the parking lot cloud, and may determine that there is a drivable-in place without an internal congestion condition if there is a congestion condition of a certain drivable-in place that is indicated as not congested, and may determine that there is a drivable-in place without an internal congestion condition if all the congestion conditions of the drivable-in places are indicated as congested.
The drivable place without congestion in the interior needs not only to meet the congestion-free condition, but also to meet the condition that the drivable place is closer to the destination, for example, the drivable time can be saved. The invention relates to a navigation method, which comprises the steps of selecting a navigation route, selecting a route from a plurality of routes, and judging the route according to the selection. When the situation that the traffic jam occurs on the front route is judged, whether non-public roads such as parking lots, gas stations and residential areas exist in front or not is judged. If the places such as an outworking parking lot, a gas station and a residential area are judged to be in front of the place, and the route passing through the place can save time or is close to a destination, whether congestion conditions exist in the place is judged, when the situation that the inside is not congested is found through place cloud display, a user is prompted to select a plurality of places meeting the conditions, when the user selects the corresponding place, the vehicle is guided to travel to an exit position of the place capable of entering according to the selected navigation route, and the navigation route is recalculated and updated based on the exit position and the destination information of the place capable of entering, so that the user can conveniently avoid the congested road section, the user can be helped to reach the target position more quickly, and the user experience is improved.
In summary, in the real-time road condition navigation method provided by the embodiment of the present invention, the initial navigation route from the current position to the destination of the vehicle is obtained according to the current position information and the destination information of the vehicle by obtaining the current position information and the destination information of the vehicle; the method comprises the steps that in the process that a vehicle runs along a current initial navigation route, the road condition of the initial navigation route is obtained in real time, and if the situation that congestion occurs in the front is known, whether a place capable of being driven into the current road section exists or not is judged; if judging that the current road section has the drivable-in place, judging whether the drivable-in place without internal congestion exists; if the drivable-in place without the internal congestion condition exists, the entrance position of the drivable-in place without the internal congestion condition is obtained, the exit position which is close to the destination position and can avoid the congestion ahead of the drivable-in place is obtained, a plurality of navigation routes of the drivable-in place are obtained according to the entrance position and the exit position for selection, the vehicle is guided to drive to the exit position of the drivable-in place according to the selected navigation route, and the navigation route is recalculated and updated based on the exit position and the destination information of the drivable-in place, so that the user can be helped to bypass the road section with serious congestion, the user can be helped to reach the target position more quickly, the user requirement is met, and the user experience is good.
