To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.
A first embodiment of the present disclosure provides a data processing method, a flow of which is shown in fig. 1, including steps S101 to S103:
s101, obtaining characteristic information of the traffic blocking incident, wherein the characteristic information at least comprises first position information of the traffic blocking incident.
The information issued by the information intelligence board (such as VMS) can easily influence the driving track of the driver, for example, when a traffic blocking event occurs, the information can be used as an important factor for bypassing the switching behavior, and the displayed traffic dispersion information can be intelligently generated according to the information such as the position, the level, the type and the like of the blocking event, so as to achieve the optimal inducing effect.
When an emergency traffic blocking event occurs, related information about the traffic blocking event is received, and in the embodiment of the disclosure, feature information required to be used is extracted from the traffic blocking event, for example, location information of the occurrence of the traffic blocking event, that is, first location information. Of course, in order to further enrich the accuracy and richness of the traffic dispersion information published on the information board, the time information, reason information, blocking direction information, severity information and the like of the traffic blocking event can be further acquired.
For example, when there is first location information and time information, the traffic dispersion information may display "a hour and B minutes, and a traffic accident occurred 1000 meters ahead"; when the first position information, the time information and the blocking direction information exist, the traffic dispersion information can display the time A and the time B, and a traffic accident happens at a place which is 1000 meters ahead in a straight line.
And S102, determining a display rule and traffic dispersion information of the traffic blocking incident based on the characteristic information of the traffic blocking incident and the second position information of the information intelligence board, wherein the traffic dispersion information at least comprises predicted passing time and/or a detour path meeting a preset condition.
After the first location information is determined, the traffic dispersion information of the traffic blocking event needs to be published on which information boards, and the location information of the information boards, namely the second location information, can be determined. In the process, the number of the information boards can be large, and the traffic number issued on each information board can be determined to the display rule corresponding to the information based on the second position information corresponding to each information board and the characteristic information of the traffic blocking incident.
The most basic content of the traffic evacuation information is basic information of the traffic blocking event, such as the first location information, and of course, the traffic evacuation information in this embodiment further includes at least an expected transit time and/or a detour route satisfying a predetermined condition. After the predicted passing time is increased and/or the detour paths meeting the preset conditions are/is increased, the traffic can be dredged more reasonably, for example, when the detour paths with shorter running time exist, the user can detour according to the detour paths without slowly advancing on the road section of the traffic blocking event or being blocked on the road section of the traffic blocking event.
S103, displaying the traffic dispersion information on the information board according to the display rule.
For the display rule, it may be arbitrarily set, for example, that an information message board whose distance from the first position is less than a predetermined distance threshold value uses a first display rule, and an information message board exceeding the predetermined distance threshold value has a second display rule, wherein the first display rule is display time information, blocking direction information, first position information, predicted passing time, and detour path satisfying a predetermined condition, and the second display rule is display time information and first position information. Of course, the above display rules are only examples, and those skilled in the art can set the display rules according to the size, requirement, etc. of the information intelligence board, so that the corresponding display rules can be directly used in the display rule base when a traffic blocking event occurs.
The embodiment of the disclosure determines the display rule and the traffic dispersion information according to the characteristic information of the traffic blocking event and the position information of the information board, not only can let the driver on the road know that the traffic blocking event exists, but also can let the driver know the predicted traffic time or detailed traffic dispersion information such as the detour path and the like, and directly display according to the display rule, the whole process does not need manual participation, the processing timeliness is stronger, and the finally displayed traffic dispersion information is uniformly high, and the dispersion effect is better.
A second embodiment of the present disclosure provides a data processing method, which describes a process of determining a predicted transit time, and the flow of the method is shown in fig. 2, and includes steps S201 to S205:
s201, acquiring characteristic information of the traffic blocking incident, wherein the characteristic information at least comprises first position information of the traffic blocking incident.
The information issued by the information intelligence board (such as VMS) can easily influence the driving track of the driver, for example, when a traffic blocking event occurs, the information can be used as an important factor for bypassing the switching behavior, and the displayed traffic dispersion information can be intelligently generated according to the information such as the position, the level, the type and the like of the blocking event, so as to achieve the optimal inducing effect.
When an emergency traffic blocking event occurs, related information about the traffic blocking event is received, and in the embodiment of the disclosure, feature information required to be used is extracted from the traffic blocking event, for example, location information of the occurrence of the traffic blocking event, that is, first location information. Of course, in order to further enrich the accuracy and richness of the traffic dispersion information published on the information board, the time information, reason information, blocking direction information, severity information and the like of the traffic blocking event can be further acquired.
For example, when there is first location information and time information, the traffic dispersion information may display "a hour and B minutes, and a traffic accident occurred 1000 meters ahead"; when the first position information, the time information and the blocking direction information exist, the traffic dispersion information can display the time A and the time B, and a traffic accident happens at a place which is 1000 meters ahead in a straight line.
S202, determining a display rule of the traffic blocking incident based on the characteristic information of the traffic blocking incident and the second position information of the information intelligence board.
After the first location information is determined, the traffic dispersion information of the traffic blocking event needs to be published on which information boards, and the location information of the information boards, namely the second location information, can be determined. In the process, the number of the information boards can be large, and the traffic number issued on each information board can be determined to the display rule corresponding to the information based on the second position information corresponding to each information board and the characteristic information of the traffic blocking incident.
S203, acquiring traffic flow speed information of the corresponding area based on the first position information and the second position information.
In particular implementations, the traffic flow rate information may be traffic flow rate information for a road segment between the first location and the second location, such as vehicle speed information for a particular vehicle on the road segment, and of course, the traffic flow rate information may also be average vehicle speed information of real-time vehicle speed information for a plurality of vehicles in order to more accurately determine the predicted transit time for the road segment.
And S204, determining a first expected passing time based on the first position information, the second position information and the traffic flow speed information.
After the first position information and the second position information are determined, the distance from the information message board of the traffic dispersion information to be released to the traffic blocking incident can be determined, the speed information from the information message board of the traffic dispersion information to be released to the traffic blocking incident can be known, and the first expected passing time (i.e. the expected passing time in the first embodiment) passing through the road section can be estimated.
The process of determining the first expected transit time of S203 and S204 described above may be performed simultaneously with the process of determining the display rule of S202.
The most basic content of the traffic dispersion information is basic information of a traffic blocking event, such as the first location information, and of course, the traffic dispersion information in this embodiment further includes an expected transit time. After the predicted passing time is increased, the traffic can be dredged more reasonably.
In the calculation, the first predicted transit time may be corrected according to the historical transit time of the corresponding area for the accuracy of the first predicted transit time.
And S205, displaying the traffic dispersion information on the information board according to the display rule.
For the display rule, it may be arbitrarily set, for example, that an information message board whose distance from the first position is less than a predetermined distance threshold value uses a first display rule, and an information message board exceeding the predetermined distance threshold value has a second display rule, wherein the first display rule is display time information, blocking direction information, first position information, predicted passing time, and detour path satisfying a predetermined condition, and the second display rule is display time information and first position information. Of course, the above display rules are only examples, and those skilled in the art can set the display rules according to the size, requirement, etc. of the information intelligence board, so that the corresponding display rules can be directly used in the display rule base when a traffic blocking event occurs.
This disclosed embodiment confirms display rule and traffic guidance information according to the characteristic information of traffic blocking incident and the positional information of information board, can not only let the driver on the road know that there is the traffic blocking incident, can also let the driver know detailed traffic guidance information to directly show according to the display rule, whole process does not need artifical the participation, handles the ageing stronger, and finally the traffic guidance information that shows is unified highly, and the guidance effect is better.
A third embodiment of the present disclosure provides a data processing method, which describes a process of determining a detour path and a predicted transit time that satisfy a predetermined condition, as compared with the first embodiment, and the flow of the method is shown in fig. 3, and includes steps S301 to S312:
s301, acquiring characteristic information of the traffic blocking incident, wherein the characteristic information at least comprises first position information of the traffic blocking incident.
The information issued by the information intelligence board (such as VMS) can easily influence the driving track of the driver, for example, when a traffic blocking event occurs, the information can be used as an important factor for bypassing the switching behavior, and the displayed traffic dispersion information can be intelligently generated according to the information such as the position, the level, the type and the like of the blocking event, so as to achieve the optimal inducing effect.
When an emergency traffic blocking event occurs, related information about the traffic blocking event is received, and in the embodiment of the disclosure, feature information required to be used is extracted from the traffic blocking event, for example, location information of the occurrence of the traffic blocking event, that is, first location information. Of course, in order to further enrich the accuracy and richness of the traffic dispersion information published on the information board, the time information, reason information, blocking direction information, severity information and the like of the traffic blocking event can be further acquired.
For example, when there is first location information and time information, the traffic dispersion information may display "a hour and B minutes, and a traffic accident occurred 1000 meters ahead"; when the first position information, the time information and the blocking direction information exist, the traffic dispersion information can display the time A and the time B, and a traffic accident happens at a place which is 1000 meters ahead in a straight line.
S302, determining a display rule of the traffic blocking incident based on the characteristic information of the traffic blocking incident and the second position information of the information intelligence board.
After the first location information is determined, the traffic dispersion information of the traffic blocking event needs to be published on which information boards, and the location information of the information boards, namely the second location information, can be determined. In the process, the number of the information boards can be large, and the traffic number issued on each information board can be determined to the display rule corresponding to the information based on the second position information corresponding to each information board and the characteristic information of the traffic blocking incident.
S303, traffic flow speed information of a corresponding region based on the second position information and position information of a predetermined end point is acquired, wherein the predetermined end point is determined by the first position information.
When a vehicle runs on a certain road, if a traffic blocking event occurs in front of the vehicle, drivers who run on the road are informed of the traffic blocking event through the information board, so that the starting point of a detour path is the position where the drivers see the information board. For the predetermined end point, when it is set, since most people are driving straight ahead on the road, the embodiment of the present disclosure sets it as a certain position point after the first position, for example, the predetermined end point may be a road exit within three kilometers downstream of the first position. Of course, if there are a plurality of road exits, which may be calculated for each exit, a plurality of detour routes having different predetermined end points may be obtained, but the purpose of this embodiment is to break out traffic, and therefore, the predetermined end point of the detour route displayed by the current information sign may be a road exit closer to the first position at the time of specific selection.
And S304, determining at least one detour path based on the second position information, the position information of the preset terminal and the traffic flow speed information.
When the starting point and the end point are determined, at least one detour path can be determined, but whether the detour path can become a final detour path meeting the preset condition needs to be further determined.
S305, detecting whether the detour path comprises a congestion road section corresponding to the traffic blocking event. If so, S306 is performed, otherwise S307 is performed.
If the congested road section corresponding to the traffic blocking event is included, it is indicated that the current detour path cannot really realize detour, otherwise, as long as the congested road section corresponding to the traffic blocking event is not included, the detour path meeting the predetermined condition can be determined.
And S306, deleting the detour path comprising the congestion road section under the condition that the congestion road section is included, so that the detour path is not recommended. Execution continues with S305.
And S307, under the condition that the congested road section is not included, determining the detour path with the shortest passing time as the detour path meeting the preset condition.
In a specific implementation, the detour path meeting the predetermined condition may be not only one or more detour paths with the shortest transit time, but also one or more detour paths with transit times smaller than a certain value, so that one or more detour paths meeting the predetermined condition may be provided.
And S308, acquiring traffic flow speed information of the corresponding area based on the first position information and the second position information.
In particular implementations, the traffic flow rate information may be traffic flow rate information for a road segment between the first location and the second location, such as vehicle speed information for a particular vehicle on the road segment, but of course, the traffic flow rate information may also be average vehicle speed information for real-time vehicle speeds of a plurality of vehicles in order to more accurately determine the predicted transit time on the road segment.
S309, determining a first expected transit time based on the first position information, the second position information and the traffic flow speed information.
After the first position information and the second position information are determined, the distance from the information message board of the traffic dispersion information to be released to the traffic blocking incident can be determined, the speed information from the information message board of the traffic dispersion information to be released to the traffic blocking incident can be known, and the first expected passing time (i.e. the expected passing time in the first embodiment) passing through the road section can be estimated.
S310, second expected passing time of the detour path with the shortest passing time is obtained.
The detour route with the shortest passing time is determined to be the detour route meeting the predetermined condition, but in order to further determine whether the detour route is the optimal detour route, whether the passing time of the detour route is longer than that of normal passing through the congested road section is avoided, and whether the second predicted passing time is shorter than the first predicted passing time is further detected.
And S311, when the second expected passing time is smaller than the first expected passing time, determining the detour path with the shortest passing time as the detour path meeting the preset condition, and determining the second expected passing time as the expected passing time.
The most basic content of the traffic evacuation information is basic information of a traffic blocking event, such as the first location information, and of course, the traffic evacuation information in this embodiment further includes at least an expected transit time and a detour route satisfying a predetermined condition. After the predicted passing time and the detour paths meeting the preset conditions are increased, the traffic can be dredged more reasonably, namely the real short-time detour routes can be selected for traffic dispersion.
S312, displaying the traffic dispersion information on the information board according to the display rule.
For the display rule, it may be arbitrarily set, for example, that an information message board whose distance from the first position is less than a predetermined distance threshold value uses a first display rule, and an information message board exceeding the predetermined distance threshold value has a second display rule, wherein the first display rule is display time information, blocking direction information, first position information, predicted passing time, and detour path satisfying a predetermined condition, and the second display rule is display time information and first position information. Of course, the above display rules are only examples, and those skilled in the art can set the display rules according to the size, requirement, etc. of the information intelligence board, so that the corresponding display rules can be directly used in the display rule base when a traffic blocking event occurs.
Before displaying the traffic dispersion information, the traffic dispersion information can be archived in a database.
The first predicted passing time and the second predicted passing time are both predicted same sex times calculated for different roads, and in the calculation, the first predicted passing time or the second predicted passing time can be corrected according to the historical passing time of the corresponding area for the accuracy of the first predicted passing time and the second predicted passing time.
The embodiment of the disclosure can issue traffic dispersion information in a personalized and intelligent manner according to factors such as different traffic blocking event reasons, different distances from a place of affair and the like, so that important road network operation information is accurately transmitted to a driver, the road network information is enabled to better accord with the reading habit of the driver, no manual participation is provided in the whole process, automatic analysis and intelligent issuing of event and road condition information are realized, and scientific accuracy and issuing efficiency are improved.
A fourth embodiment of the present disclosure provides a data processing apparatus, a structural schematic of which is shown in fig. 4, including:
the acquiring module 10 is configured to acquire feature information of a traffic blocking event, where the feature information at least includes first location information of the traffic blocking event; a determining module 20, coupled to the obtaining module 10, configured to determine a display rule and traffic dispersion information of the traffic blocking event based on the characteristic information of the traffic blocking event and the second location information of the information intelligence board, where the traffic dispersion information at least includes an expected transit time and/or a detour route satisfying a predetermined condition; and a display module 30 coupled to the determination module 20 for displaying the traffic dispersion information on the information board according to the display rule.
The information issued by the information intelligence board (such as VMS) can easily influence the driving track of the driver, for example, when a traffic blocking event occurs, the information can be used as an important factor for bypassing the switching behavior, and the displayed traffic dispersion information can be intelligently generated according to the information such as the position, the level, the type and the like of the blocking event, so as to achieve the optimal inducing effect.
When an emergency traffic blocking event occurs, related information about the traffic blocking event is received, and in the embodiment of the disclosure, feature information required to be used is extracted from the traffic blocking event, for example, location information of the occurrence of the traffic blocking event, that is, first location information. Of course, in order to further enrich the accuracy and richness of the traffic dispersion information published on the information board, the time information, reason information, blocking direction information, severity information and the like of the traffic blocking event can be further acquired.
For example, when there is first location information and time information, the traffic dispersion information may display "a hour and B minutes, and a traffic accident occurred 1000 meters ahead"; when the first position information, the time information and the blocking direction information exist, the traffic dispersion information can display the time A and the time B, and a traffic accident happens at a place which is 1000 meters ahead in a straight line.
