Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flowchart illustrating steps of a first embodiment of a path recommendation method according to the present application is shown, which may specifically include the following steps:
step 101, identifying a congested road section in a driving path, and determining a bypass exit and a bypass entrance which bypass the congested road section.
In this embodiment of the present application, the travel route includes a route currently being traveled, or a route selected in a navigation recommended route, or any other suitable travel route, which is not limited in this embodiment of the present application. The congested road section refers to a road section in which a congestion condition occurs, and the manner of identifying the congested road section in the driving path may include multiple manners, for example, a server providing a navigation service identifies the congested road section according to current road condition information, the navigation device directly obtains the congested road section in the driving path from the server, or the navigation device obtains the current road condition information from the server, and identifies the congested road section in the driving path according to the road condition information, or any other suitable identification manner, which is not limited in this embodiment of the present application.
In the embodiment of the application, in order to bypass the congested road segment, an exit which can be driven out of the driving path is required to be found at a position before the congested road segment is reached, and is recorded as a bypass exit, and an entrance which can be driven back to the driving path again is required to be found at a position after the congested road segment and is recorded as a bypass entrance. For example, a congested section occurs on an expressway, and a highway exit before the congested section is a detour exit, and a highway entrance after the congested section is a detour entrance. The manner of determining the detour exit and the detour entrance may include various manners, for example, a first detour exit is searched from the beginning of the congested road section to the current position of the user, a first detour entrance is searched from the end of the congested road section to the end direction of the driving path, or a first detour exit is searched from the current position of the user to the beginning of the congested road section, a first detour entrance is searched from the end of the congested road section to the end direction of the driving path, or any other suitable manner is used to determine the detour exit and the detour entrance, which is not limited in the embodiment of the present application.
And 102, judging whether the estimated passing time from the current position to the detour exit is within a preset time range.
In this embodiment of the present application, step 101 may be executed periodically, or may be executed after updating the traffic information each time, or may be executed in any other suitable manner, which is not limited in this embodiment of the present application. After identifying the congested road segment and determining the detour exit and the detour entrance, the alternative route does not need to be generated immediately, the running route is driven out, and congestion is avoided.
The current position is the current driving position, and the estimated passing time is obtained according to the distance between the current position and the detour exit and the current driving speed or the estimated driving speed, namely the estimated time spent on driving from the current position to the detour exit.
The estimated processing time is a response time reserved for a user to adjust a driving state, and may be a set fixed time value, or a time value dynamically determined according to a driving speed, for example, the estimated processing time is set to 30 seconds, or the estimated processing time is shorter as the driving speed is faster and the estimated processing time is shorter as the driving speed is slower, and specifically, any suitable manner may be used to determine the estimated processing time, which is not limited in the embodiment of the present application. The road condition updating period is a period for updating the road condition information, for example, the navigation device may obtain the latest road condition information from the server in a period of 30 seconds (i.e., the road condition updating period), and the updated road condition information may be specifically set according to actual needs, which is not limited in this embodiment of the application.
The preset time range is determined by the estimated processing time and the road condition updating period, and may include that the estimated passing time is smaller than a sum of the estimated processing time and the road condition updating period, or may further include that the estimated passing time is greater than the estimated processing time, and specifically, any applicable preset time range may be determined according to actual needs, which is not limited in the embodiments of the present application.
In the embodiment of the present application, before generating the alternative route, it is required to determine whether the estimated passing time from the current position to the detour exit is within the preset time range, and if the estimated passing time is within the preset time range, step 103 is executed.
And 103, if the estimated passing time is within the preset time range, generating an alternative path between the detour exit and the detour entrance, and recommending the path.
In the embodiment of the application, when the estimated transit time is within the preset time range, the alternative path can be generated to be recommended to the user. A plurality of alternative paths may be included between the detour exit and the detour entrance, the alternative paths do not include the original travel path, and specifically, a path with the shortest travel time may be generated between the detour exit and the detour entrance as the alternative path, or a path with the shortest distance may be generated as the alternative path, or a path with the fewest traffic lights may be generated as the alternative path, or any other applicable alternative path, which is not limited in this embodiment of the application.
In this application embodiment, the alternative paths may include one or more alternative paths, and after a plurality of alternative paths are generated, all the alternative paths may be recommended to the user, or a part of the alternative paths may be selected to be recommended, which is not limited in this application embodiment.
In summary, according to the embodiment of the present application, by identifying a congested road segment in a driving route, and determining a detour exit and a detour entrance which detour the congested road segment, it is determined whether an estimated passage time from a current position to the detour exit is within a preset time range, and if the estimated passage time is within the preset time range, an alternative route is generated between the detour exit and the detour entrance to perform route recommendation, so that after congestion is found, only the estimated passage time from the current position to the detour exit is within the preset time range, an alternative route is generated to perform route recommendation, and the preset time range is determined by processing time and a road condition update period, thereby avoiding a problem that the congestion condition disappears when the congestion condition reaches nearby, and avoiding congestion at the detour exit too late.
In this embodiment of the application, optionally, before the path recommendation, the method may further include:
rejecting alternative paths of which the distance exceeds a set multiple of the distance between a detour outlet and a detour inlet in the driving path;
and/or eliminating alternative paths with congestion distances exceeding a preset congestion distance in the alternative paths;
and/or eliminating alternative paths with saved time lower than preset saved time in the alternative paths.
And comparing the alternative path with the original running path between the detour exit and the detour entrance, and if the distance of the alternative path exceeds a set multiple of the distance between the detour exit and the detour entrance in the running path, rejecting the alternative path. For example, if the distance of the alternative path exceeds 1.5 times of the original driving path, the alternative path is rejected.
And if the alternative paths are congested, eliminating the alternative paths with the congestion distance exceeding the preset congestion distance. For example, if the congestion distance in the alternative path exceeds 500 meters, the alternative path is rejected.
And if the time saved by the alternative path compared with the original driving path is less than the preset time saved, rejecting the alternative path. For example, if the time saved by the alternative route is less than 10 minutes than the original travel route, the alternative route is rejected.
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a path recommendation method in the present application is shown, which may specifically include the following steps:
step 201, obtaining the road condition information of the driving path.
In the embodiment of the present application, the traffic information includes various information about driving on the driving path, such as an average driving speed, an accident location, congestion information, and the like, or any other suitable information, which is not limited in the embodiment of the present application.
Step 202, according to the road condition information, identifying that a congested road section meeting a set road grade and exceeding a preset distance threshold exists in the driving path.
In the embodiment of the application, if the road condition information includes information of a congested road section, it is determined whether the distance of the congested road section exceeds a preset distance threshold, if so, the congested road section is identified, otherwise, the congested road section is not identified. If the road condition information only contains the average running speed, searching the road sections of which the average running speed is lower than the congestion speed threshold and the distance exceeds the preset distance threshold from the running paths, and identifying the road sections as congestion road sections. The preset distance threshold value can be specifically set according to actual needs, and the embodiment of the application is not limited to this. The manner of identifying the congested road segment may include any applicable manner, which is not limited in this application.
The scene aimed at by the application requires that the congested road section meets the set road grade, and the congested road section can be identified, for example, the congested road section is an expressway, and then the congested road section is identified, and the set road grade can be set according to actual needs, which is not limited in the embodiment of the application.
In the embodiment of the present application, optionally, in order to bypass the entire congested section, the bypass exit is located before the start point of the congested section, and the bypass entrance is located after the end point of the congested section.
And step 203, searching a first detour exit from the starting point of the congested road section to the current position along the running path.
In the embodiment of the application, one or more detour exits may exist between the current position and the starting point of the congested road section, and in order to travel on the original travel path as much as possible, the starting point of the congested road section is searched in the direction of the current position, and the first detour exit is searched and serves as the detour exit of the application.
And step 204, searching a first detour entrance from the end point of the congestion road section to the end point direction of the travel path along the travel path.
In the embodiment of the application, one or more bypass entrances may exist between the end point of the congested road segment and the end point of the driving path, and in order to drive on the original driving path as much as possible, the end point of the congested road segment is searched in the direction of the end point of the driving path, and the first bypass entrance is found and used as the bypass entrance of the application.
Step 205, determining whether the estimated transit time is less than the sum of the road condition updating period and the reserved processing time.
In the embodiment of the application, the estimated passing time is the time from the current position to the detour exit, and the user drives to the detour exit, so that after the congested road section is identified, whether the estimated passing time is less than the sum of the road condition updating period and the reserved processing time is judged, and if the estimated passing time is not less than the sum of the road condition updating period and the reserved processing time, the distance between the current position and the detour exit is still far, and early reminding is not needed. If the estimated passing time is less than the sum of the road condition updating period and the reserved processing time, namely the estimated passing time is within the preset time range, the current position is close enough to the detour exit, and the reminding is not too early. In practical application, the judgment can be carried out circularly at a very fast frequency, that is, the alternative path to be recommended cannot be generated too long after the estimated passing time is less than the sum of the road condition updating period and the reserved processing time, and the alternative path is not bypassed, so that the condition that the reminding is too late is avoided.
For example, if the estimated traffic time is greater than the sum of two traffic update periods and the reserved processing time, the current position is far away from the detour exit, and there is a time to update the traffic information once in the process of approaching the detour exit, there may be a possibility that the congested road section recovers smoothly after updating the traffic information again, but when the vehicle travels for a certain time and is judged again, the estimated traffic time is less than the sum of the traffic update periods and the reserved processing time, the current position is not far away from the detour exit, and the traffic information is not updated again before the distance which can be traveled by the reserved processing time from the detour exit, and at this time, an alternative path can be generated for recommendation.
In this embodiment of the present application, optionally, determining whether the estimated transit time from the current position to the detour exit is within a preset time range further includes: and judging whether the estimated passing time is greater than the reserved processing time.
In order to have enough reserved processing time, it is necessary to ensure that the estimated transit time is greater than the reserved processing time before the path recommendation. In practical application, when a congested road section is identified, the current position is close to a detour exit, at this time, although the estimated passing time is smaller than the sum of a road condition updating period and reserved processing time, if the estimated passing time is not greater than the reserved processing time, a driving path cannot be driven out, and the detour exit is missed, so that whether the estimated passing time is greater than the reserved processing time or not needs to be judged first, if the estimated passing time is greater than the reserved processing time, an alternative path is generated within a preset time range, otherwise, the path is not recommended, and the situation that the recommendation is carried out too late, so that meaningless recommendation is provided for a user, the use experience is influenced, and even the driving safety of the user is influenced can be avoided.
And step 206, if the estimated passing time is within the preset time range, generating an alternative path between the detour exit and the detour entrance, and recommending the path.
In the embodiment of the present application, a specific implementation manner of this step may refer to the description in the foregoing embodiment, and is not described herein again.
To sum up, according to the embodiment of the present application, by obtaining the traffic information of the travel route, according to the traffic information, identifying a congested road segment meeting a set road grade and exceeding a preset distance threshold in the travel route, searching a first detour exit from a start point of the congested road segment to a current position along the travel route, searching a first detour entrance from an end point of the congested road segment to an end point direction of the travel route along the travel route, determining whether an estimated transit time is less than a sum of a traffic update period and a reserved processing time, if the estimated transit time is within a preset time range, generating an alternative route between the detour exit and the detour entrance, and performing route recommendation, so that after congestion is found, an alternative route is generated for route recommendation only if the estimated transit time from the current position to the detour exit is within the preset time range, and the preset time range is determined by the estimated processing time and the traffic update period, the problem that the congestion condition disappears when the alternative route is generated too early and the nearby place is reached is solved, and the problem that the alternative route is generated too late and the bypass exit is missed so that the congestion cannot be avoided is also solved.
