The determination method of the traffic operation state of the monitored road section is the same as the traffic operation method of the monitored road section in the embodiment shown in fig. 4 to 5, and is not described herein again.
As shown in fig. 4, a flow chart of another embodiment of a road monitoring method provided in the embodiment of the present invention may include the following steps:
401: and monitoring the traffic flow passing through the first monitoring position to obtain first monitoring data.
Optionally, monitoring the traffic flow passing through the first monitoring location, and obtaining the first monitoring data may include: and monitoring vehicles passing through the road cross section corresponding to the first monitoring position to obtain first monitoring data.

Before monitoring the traffic flow passing through the first monitoring position and obtaining the first monitoring data, the method may further include: and determining a first monitoring position and a second monitoring position.
The first monitoring location and the second monitoring location may refer to any two adjacent monitoring locations in the target road segment. At least two monitoring positions can be arranged in the target road section to monitor different positions of the target road section respectively, so that at least one monitoring road section is formed, and segmented monitoring of the target road section is realized.
The first monitoring position and the second monitoring position may actually be positions at both ends of any monitoring road segment, so as to monitor the monitoring road segment.
403: and if the first monitoring data and the second monitoring data meet abnormal monitoring conditions, determining that the monitoring road sections corresponding to the first monitoring position and the second monitoring position are in abnormal operation states.
The traffic operation state of the monitored section may include an abnormal operation state as well as a normal operation state.
For the first monitoring position and the second monitoring position, the first monitoring data of the first monitoring position can be obtained by monitoring the traffic flow passing through the first monitoring position, the second monitoring data of the second monitoring position can be obtained by monitoring the traffic flow passing through the second monitoring position, the automatic monitoring of the corresponding monitoring road sections of the first monitoring position and the second monitoring position is realized by judging whether the first monitoring data and the second monitoring data meet the abnormal monitoring condition, the abnormal traffic is discovered in time, and the monitoring efficiency and the monitoring accuracy are improved.
The first monitoring data and the second monitoring data satisfying the abnormal monitoring condition may indicate that a large data difference exists between the first monitoring data and the second monitoring data, for example, for the same monitoring parameter, a data difference value between a value of the monitoring parameter in the first monitoring data and a value of the monitoring parameter in the second monitoring data is large. If the data difference between the first monitoring data and the second monitoring data is large, the abnormal traffic flow driving conditions of the two monitoring positions can be determined, so that the abnormal monitoring road sections corresponding to the two monitoring positions can be determined.
The traffic flow of the first monitoring position is monitored, and in the process of obtaining the first monitoring data, the first acquisition time of the first monitoring data can be recorded. And monitoring the traffic flow of the second monitoring position, and recording second acquisition time of the second monitoring data in the process of acquiring the second monitoring data.
When judging whether the first monitoring data and the second monitoring data meet the abnormal monitoring condition, two groups of first monitoring data and second monitoring data which are matched in time can be used for comparing to obtain an accurate comparison result.
As a possible implementation manner, when monitoring the running state of the traffic flow, a first acquisition time of the first monitoring data and a second acquisition time of the second monitoring data may be recorded, and whether the first monitoring data and the second monitoring data satisfy the abnormal monitoring condition may mean that the first monitoring data and the second monitoring data satisfy the abnormal monitoring condition when the first acquisition time is the same as the second acquisition time.
As another possible implementation manner, when performing feature monitoring on a vehicle, a first collection time of first monitoring data and a second collection time of second monitoring data may be recorded, and the comparison of the vehicle features is usually a comparison of vehicle features of a certain vehicle, so that when determining whether the first monitoring data and the second monitoring data satisfy an abnormal monitoring condition, specifically, when the first collection time and the second collection time have a certain time interval, it may be determined whether the first monitoring data and the second monitoring data satisfy the abnormal monitoring condition. The time interval between the first collection time and the second collection time may refer to an expected transit time of the vehicle in the monitored road section corresponding to the first monitoring position and the second monitoring position.
As yet another embodiment, the method may further include:
and if the first monitoring data and the second monitoring data meet normal monitoring conditions, determining that the monitoring road sections corresponding to the first monitoring position and the second monitoring position are in normal operation states.
The first monitoring data and the second monitoring data satisfying the normal monitoring condition may mean that a data difference between the first monitoring data and the second monitoring data is small, for example, for the same monitoring parameter, a data difference between a value of the monitoring parameter in the first monitoring data and a value of the monitoring parameter in the second monitoring data is small. If the data difference between the first monitoring data and the second monitoring data is small, the traffic flow driving conditions of the two monitoring positions can be determined to be normal, and then the running states of the monitoring road sections corresponding to the two monitoring positions are determined to be normal.
The traffic flow passing through the two monitoring positions is monitored to obtain corresponding monitoring data, and then the running state of the monitored road section is judged by judging whether the monitoring data are abnormal or not. When the monitored road section is in the abnormal operation state, prompt information can be output to prompt the traffic operation state of the monitored road section. As an embodiment, the method may further comprise:
and outputting prompt information that the first monitoring position and the second monitoring position correspond to the monitoring road section in an abnormal operation state.
As shown in fig. 5, a flow chart of another embodiment of a road monitoring method provided in an embodiment of the present invention may include the following steps:
501: and monitoring the traffic flow passing through the first monitoring position to obtain first monitoring data.
502: and monitoring the traffic flow passing through the second monitoring position to obtain second monitoring data.
Some steps of the embodiment of the present invention are the same as those of the embodiment shown in fig. 4, and are not repeated herein.
503: and if the first monitoring data and the second monitoring data meet the abnormal monitoring condition, determining the monitoring interval and the monitoring times.
504: and continuously monitoring the traffic flow of the first monitoring position and the traffic flow of the second monitoring position according to the monitoring times based on the monitoring interval to obtain updated first monitoring data and second monitoring data.
Based on the monitoring interval and according to the monitoring times, continuously monitoring the traffic flow of the first monitoring position and the traffic flow of the second monitoring position, and obtaining the updated first monitoring data and second monitoring data may include: monitoring the traffic flow of the first monitoring position according to the monitoring interval and the monitoring times, updating the first monitoring data, monitoring the traffic flow of the second monitoring position, and updating the second monitoring data; and judging whether the first monitoring data and the second monitoring data meet abnormal monitoring conditions or not aiming at the first monitoring data and the second monitoring data which are updated each time so as to determine the traffic running states of the monitoring road sections corresponding to the first monitoring position and the second monitoring position.
505: and if the first monitoring data and the second monitoring data after each updating meet the abnormal monitoring condition, determining that the monitoring road sections corresponding to the first monitoring position and the second monitoring position are in an abnormal operation state.
For the first monitoring data and the second monitoring data updated each time, whether the first monitoring data and the second monitoring data meet the abnormal monitoring condition can be judged, and then the monitoring road sections corresponding to the first monitoring position and the second monitoring position are determined to be in the abnormal operation state.
The updated first monitoring data and second monitoring data continuously satisfy the abnormal monitoring condition, which may mean that there is a large data difference between the first monitoring data and the second monitoring data.
In the embodiment of the invention, if the monitored road sections corresponding to the first monitoring position and the second monitoring position are monitored to be in the abnormal operation state, the possibility of misjudgment is high when the monitored road sections are in the abnormal operation state through only one-time judgment, the first monitoring position and the second monitoring position can be continuously monitored according to the monitoring times at intervals so as to obtain the first monitoring data and the second monitoring data obtained by each monitoring, whether the updated monitoring data meets the abnormal monitoring condition or not is judged, if the updated first monitoring data and the updated second monitoring data meet the abnormal monitoring condition, the continuous data mutation of the monitoring data of the monitored road sections can be judged, and the monitoring road sections corresponding to the first monitoring position and the second monitoring position can be accurately determined to be in the abnormal operation state through the mode.
In order to obtain a more accurate monitoring result, in the process of monitoring the traffic flow of the first monitoring position and the traffic flow of the second monitoring position, the abnormal operation state can be accurately judged by acquiring the vehicle characteristics of the vehicle. Therefore, as shown in fig. 6, the difference from the embodiment shown in fig. 5 is that the step 505: if the first monitoring data and the second monitoring data after each update both satisfy the abnormal monitoring condition, determining that the monitoring section corresponding to the first monitoring position and the second monitoring position is in the abnormal operation state may include:
601: and if the first monitoring data and the second monitoring data after each updating meet the abnormal monitoring condition, acquiring the vehicle characteristic data of the vehicle passing through the first monitoring position, acquiring the first characteristic data, acquiring the vehicle characteristic data of the vehicle passing through the second monitoring position, and acquiring the second characteristic data.
602: and if the first characteristic data and the second characteristic data have characteristic data difference, determining that the monitoring road sections corresponding to the first monitoring position and the second monitoring position are in an abnormal operation state.
The first characteristic data may include vehicle characteristic data of at least one vehicle passing through the first monitored location, and the second characteristic data may include vehicle characteristic data of at least one vehicle passing through the second monitored location.
Alternatively, the vehicle feature data of the vehicle may refer to license plate feature data formed by license plates of the vehicle, or image feature data formed by collected images of the vehicle, and the like.
As an embodiment, the determining that the monitored section corresponding to the first monitoring position and the second monitoring position is in the abnormal operation state if the first characteristic data and the second characteristic data have characteristic data difference may include:
and aiming at the vehicle characteristic data of any vehicle, if the first characteristic data and the second characteristic data do not contain the vehicle characteristic data simultaneously, determining that the monitoring road section corresponding to the first monitoring position and the second monitoring position is in an abnormal operation state.
When the monitoring road sections corresponding to the first monitoring position and the second monitoring position are determined to be in the abnormal operation state, any vehicle needs to sequentially pass through the first monitoring position and the second monitoring position, or should sequentially pass through the first monitoring position and the second monitoring position according to the driving direction.
And the time difference value of the first acquisition time corresponding to the first characteristic data and the second acquisition time corresponding to the second characteristic data is the predicted passing time of any vehicle in a monitoring road section formed by the first monitoring position and the second monitoring position. The estimated transit time is the quotient of the length of the monitored road segment and the average traveling speed of the vehicle. In order to avoid misjudgment, the preset passing time can be calculated based on the minimum vehicle speed, and the passing time of any vehicle passing through the monitoring road section formed by the first monitoring position and the second monitoring position is obtained. When the preset passing time is determined based on the passing time, the waiting time can be obtained, and the preset passing time is obtained by adding the waiting time and the preset passing time. And misjudgment can be further avoided through waiting time, and the monitoring accuracy is improved.
Optionally, if the first characteristic data at the first collecting time is different from the second characteristic data at the second collecting time, it may be determined that the monitored road sections corresponding to the first monitoring position and the second monitoring position are in an abnormal operation state, and it may also be determined that a vehicle corresponding to the vehicle characteristic data that does not exist in the first characteristic data and the second characteristic data at the same time has abnormal driving. The time interval between the first acquisition time and the second acquisition time is the predicted transit time.
In the process that the vehicle runs on the monitoring road section corresponding to the first monitoring position and the second monitoring position, if abnormal running states such as congestion and the like occur in the monitoring road section, the vehicle cannot arrive at the other monitoring position from one monitoring position within the estimated traffic time, therefore, the collected first characteristic data of the first monitoring position can be compared with the second characteristic data of the second monitoring position to judge whether the first characteristic data and the second characteristic data have difference of the characteristic data, further judge whether conditions such as vehicle loss and the like exist between the first monitoring position and the second monitoring position, and determine the traffic running state of the monitoring road section through the monitoring vehicle.
In order to obtain an accurate monitoring result, various states of traffic flow passing through any monitoring position can be monitored, and traffic flow state parameters can reflect the vehicle running conditions of the monitoring position, so that as an embodiment, the first monitoring data comprises first parameter data corresponding to the traffic flow state parameters; the second monitoring data comprise second monitoring data corresponding to the traffic flow state parameters;
the monitoring of the traffic flow passing through the first monitoring location, and the obtaining of the first monitoring data comprises:
monitoring traffic flow passing through the first monitoring position based on traffic flow state parameters to obtain first parameter data corresponding to the traffic flow state parameters;
the monitoring of the traffic flow passing through the second monitoring position, and the obtaining of the second monitoring data includes:
and monitoring the traffic flow passing through the second monitoring position based on the traffic flow state parameters to obtain second parameter data corresponding to the traffic flow state parameters.
When the first parameter data is obtained, a first acquisition time at that time may be recorded. When the second parameter data is obtained, a second acquisition time at this time may be recorded. The embodiment of the invention monitors the traffic flow on a certain road section to obtain corresponding monitoring data, and for the road section, the road section can be determined to be in a normal operation state when the monitoring data of the traffic flow obtained at different monitoring positions are the same at the same monitoring time, and the road section can be determined to be in an abnormal operation state when the monitoring data obtained at different monitoring positions are different at the same monitoring time.
Therefore, the determining that the monitored road sections corresponding to the first monitoring position and the second monitoring position are in the abnormal monitoring state may include: and if the first acquisition time of the first monitoring data is the same as the second acquisition time of the second monitoring data, determining that the monitoring road sections corresponding to the first monitoring position and the second monitoring position are in an abnormal monitoring state if the first monitoring data and the second monitoring data meet abnormal monitoring conditions.
After the traffic flow state is monitored and the parameter data of each traffic flow state parameter is obtained, the running state of the monitored road section can be judged by using the parameter data of the traffic flow state parameters. As another embodiment, if the first monitoring data and the second monitoring data satisfy an abnormal monitoring condition, determining that the monitored road segment corresponding to the first monitoring position and the second monitoring position is in an abnormal operating state includes:
and if the first parameter data and the second parameter data corresponding to the traffic flow state parameters are different, determining that the monitoring road sections corresponding to the first monitoring position and the second monitoring position are in an abnormal operation state. Optionally, the traffic flow state parameters may include a plurality of traffic flow state parameters, the first parameter data may include parameter data corresponding to the plurality of traffic flow state parameters, and the second parameter data may include parameter data corresponding to the plurality of traffic flow state parameters.
The difference between the first parameter data and the second parameter data corresponding to the traffic flow state parameters may mean that, for each traffic flow state parameter, the parameter data of the parameter in the first parameter data is different from the parameter data of the parameter in the second parameter data.
In one possible design, the traffic state parameters include: a traffic flow parameter, a vehicle speed parameter and/or a road occupancy parameter;
the monitoring of the traffic flow passing through the first monitoring position based on the traffic flow state parameters, and the obtaining of the first parameter data corresponding to the traffic flow state parameters includes:
monitoring the traffic flow passing through the first monitoring position based on the traffic flow parameter, the vehicle speed parameter and/or the road occupancy parameter to obtain a first traffic flow, a first vehicle speed and/or a first road occupancy;
the monitoring of the traffic flow passing through the second monitoring position based on the traffic flow state parameters, and the obtaining of the second parameter data corresponding to the traffic flow state parameters includes:
and monitoring the traffic flow passing through the second monitoring position based on the traffic flow parameter, the vehicle speed parameter and/or the road occupancy parameter to obtain a second traffic flow, a second vehicle speed and/or a second road occupancy.
Alternatively, the traffic flow may refer to the number of vehicles passing through a road cross section corresponding to a certain monitoring position in unit time, the vehicle speed may refer to the speed of the vehicles passing through the road cross section corresponding to the certain monitoring position, and the road occupancy may refer to the proportion of the monitored road section covered by the vehicles on the monitored road section. In the course of the monitored route section, the operating state of the monitored route section can be determined from the monitoring result of the at least one traffic state parameter. As a possible implementation manner, when the monitoring result of one traffic flow state parameter is abnormal, that is, it is determined that the monitored road section is in the abnormal operation state, and when it is determined that the monitoring results of a plurality of traffic flow states are abnormal, it is determined that the monitored road section is in the abnormal operation state.
Optionally, a traffic flow at the first monitoring position may be monitored by using a flow monitoring device or a video flow detection algorithm to obtain a first traffic flow corresponding to the traffic flow parameter, and a traffic flow at the second monitoring position may be monitored to obtain a second traffic flow corresponding to the traffic flow parameter.
Optionally, the speed of at least one vehicle passing through the first monitoring location may be obtained; and determining a first vehicle speed corresponding to the vehicle speed parameter according to the respective vehicle speed of the at least one vehicle. The speed of at least one vehicle passing through the second monitoring location may be obtained; and determining a second vehicle speed corresponding to the vehicle speed parameter according to the respective vehicle speed of at least one vehicle. The speed of the vehicle passing through each monitoring position can be obtained by monitoring the vehicle speed monitoring equipment and can also be determined by acquiring the GPS positions uploaded by the vehicle at different times.
Optionally, a road monitoring algorithm may be used to monitor the traffic flow of the first monitoring position to obtain a first road occupancy corresponding to the road occupancy parameter, and monitor the traffic flow of the second monitoring position to obtain a second road occupancy corresponding to the road occupancy parameter.
Therefore, in the traffic flow monitoring process, if parameter data corresponding to parameters such as a traffic flow parameter, a vehicle speed parameter, and/or a road occupancy parameter are monitored, as a possible implementation manner, in order to accurately monitor a road, if the first monitoring data and the second monitoring data satisfy an abnormal monitoring condition, determining that a monitored road segment corresponding to the first monitoring position and the second monitoring position is in an abnormal operation state includes:
and if the first vehicle flow is different from the second vehicle flow, the first vehicle speed is different from the second vehicle speed, and/or the first road occupancy is different from the second road occupancy, determining that the monitoring road section corresponding to the first monitoring position and the second monitoring position is in an abnormal operation state.
Through monitoring of different traffic flow state parameters, the running condition of the vehicle on the monitored road section can be determined and obtained, so that the running condition of the monitored road section is determined, and an accurate running state judgment result is obtained.
In some embodiments, in the process of monitoring a road, in addition to monitoring the running condition of the road, direct monitoring may be performed on vehicles on the road, and the accurate running condition of the road is obtained by monitoring the running condition of the vehicles, where the first monitoring data may include third characteristic data, and the second monitoring location includes fourth characteristic data;
the monitoring of the traffic flow passing through the first monitoring location, and the obtaining of the first monitoring data includes:
monitoring vehicle characteristic data of the vehicle passing through the first monitoring position to obtain third characteristic data;
the monitoring of the traffic flow passing through the second monitoring position, and the obtaining of the second monitoring data includes:
and monitoring the vehicle characteristic data of the vehicle passing through the second monitoring position to obtain fourth characteristic data.
The third characteristic data may include vehicle characteristic data of the at least one vehicle passing through the first monitored location and the fourth characteristic data may include vehicle characteristic data of the at least one vehicle passing through the second monitored location.
Alternatively, the vehicle feature data of the vehicle may refer to license plate feature data formed by license plates of the vehicle, or image feature data formed by collected images of the vehicle, and the like.
And the time difference value of the third acquisition time corresponding to the third characteristic data and the fourth acquisition time corresponding to the fourth characteristic data is the predicted passing time of any vehicle in a monitoring road section formed by the first monitoring position and the second monitoring position. The estimated transit time is the quotient of the length of the monitored road segment and the average traveling speed of the vehicle.
In some possible designs, if the first monitoring data and the second monitoring data satisfy an abnormal monitoring condition, determining that the monitoring section corresponding to the first monitoring position and the second monitoring position is in an abnormal operating state may include:
and if the third characteristic data and the fourth characteristic data have characteristic data difference, determining that the monitoring road sections corresponding to the first monitoring position and the second monitoring position are in an abnormal operation state.
If data difference exists between the third characteristic data acquired at the third acquisition time and the fourth characteristic data acquired at the fourth acquisition time, the monitoring road section corresponding to the first monitoring position and the second monitoring position can be determined to be in an abnormal operation state. And the time difference value between the third acquisition time and the fourth acquisition time is the predicted passing time.
As a possible implementation manner, whether there is a difference between the third feature data and the fourth feature data is determined by:
and determining that the third characteristic data is different from the fourth characteristic data if the third characteristic data and the fourth characteristic data do not contain the vehicle characteristic data aiming at the vehicle characteristic data of any vehicle.
Specifically, if the third characteristic data and the fourth characteristic data do not include the vehicle characteristic data of a certain vehicle, the fourth characteristic data may include the vehicle characteristic data of the certain vehicle, or the third characteristic data does not include the vehicle characteristic data of the certain vehicle, and the fourth characteristic data includes the vehicle characteristic data of the certain vehicle.
As another possible implementation manner, whether there is a difference between the third feature data and the fourth feature data is determined by:
determining a first time of occurrence of the vehicle at a first monitoring location and a second time of occurrence of the vehicle at a second monitoring location based on vehicle characteristic data of any one vehicle;
and if the time interval between the first appearance time and the second appearance time is larger than the preset passing time, determining that the third characteristic data and the fourth characteristic data have characteristic data difference.
When any vehicle passes through the first monitoring position, the vehicle characteristic data of the vehicle can be collected, third characteristic data is obtained, and the first occurrence time of the vehicle at the first monitoring position is recorded; similarly, when any vehicle passes through the second monitoring position, the vehicle characteristic data of the vehicle can be collected, the fourth characteristic data is obtained, and the second occurrence time of the vehicle at the second monitoring position is recorded.
Optionally, the first time of occurrence of the vehicle at the first monitoring position is a third collecting time of the third characteristic data, and the second time of occurrence of the vehicle at the second monitoring position is a fourth collecting time of the fourth characteristic data.
The time interval between the first occurrence time and the second occurrence time is greater than the preset passing time, which indicates that the time difference between the third acquisition time of the vehicle characteristic data at the first monitoring position and the fourth acquisition time of the second monitoring position is greater than the preset passing time, that is, the vehicle passes through the first monitoring position and the second monitoring position in sequence after a long time, and it can be judged that the monitoring section corresponding to the first monitoring position and the second monitoring position needs to be greater than the preset passing time to pass through the monitoring section, and the monitoring section is in an abnormal passing state.
When any vehicle sequentially passes through the first monitoring position and the second monitoring position, as another possible implementation manner, whether the third characteristic data and the fourth characteristic data have characteristic differences may be determined by:
determining a third time of occurrence of any one of the vehicles at the first monitoring location based on the vehicle characteristic data;
calculating a fourth time of occurrence of the vehicle at a second monitoring location predicted based on a preset interval time;
determining that the third characteristic data differs from the fourth characteristic data if the vehicle is not present at the second monitored location at the fourth time.
If the vehicle passes the first monitoring location but does not pass the second monitoring location, it may be determined that the vehicle has an anomaly in the monitored road segment.

If the data difference between the first monitoring data and the second monitoring data is small, the traffic flow driving conditions of the two monitoring positions can be determined to be normal, and then the running states of the monitoring road sections corresponding to the two monitoring positions are determined to be normal.

In the process that the vehicle runs on the monitoring road section corresponding to the first monitoring position and the second monitoring position, if abnormal running states such as congestion occur in the monitoring road section, the vehicle cannot reach another monitoring position from one monitoring position within the expected passing time, therefore, the collected first characteristic data of the first monitoring position can be compared with the second characteristic data of the second monitoring position to judge whether the first characteristic data and the second characteristic data have the difference of the characteristic data, further judge whether conditions such as vehicle loss exist between the first monitoring position and the second monitoring position, and determine the traffic running state of the monitoring road section through the monitoring vehicle.
In order to obtain an accurate monitoring result, various states of traffic flow passing through any monitoring position can be monitored, and traffic flow state parameters can reflect the vehicle running conditions of the monitoring position, so that as an embodiment, the first monitoring data comprises first parameter data corresponding to the traffic flow state parameters; the second monitoring data comprise second monitoring data corresponding to the traffic flow state parameters;
