Specific implementation mode
Hereinafter, the present invention will be described in detail with reference to various embodiments shown in the accompanying drawings.But these embodiments are not
The limitation present invention, structure that those skilled in the art are made according to these embodiments, method or change functionally
It changes and is included within the scope of protection of the present invention.
It should be noted that in various embodiments, identical label or label may be used, but these not generations
Absolute contact relationship in table structure or function.Also, also not generation such as " first " that is previously mentioned in each embodiment, " second "
Absolute differentiation relationship in table structure or function, these are merely for convenience of description.
As shown in Figure 1, road vehicle traffic behavior recognition methods flow chart in an embodiment of the present invention.Road vehicle is handed over
Passage specifically comprises the following steps for recognition methods：
Step S1, the identity for obtaining vehicle within the scope of corresponding road Identification records corresponding identity vehicle and enters the identification range
Entry time.The identity of vehicle is obtained by corresponding collecting device, corresponding road Identification range is by corresponding collecting device
Characteristic determines.Preferably, the identity of the vehicle reads the radio frequency identification installed on vehicle electricity by radio-frequency identification reader/writer
Subtab obtains, and the identification range, that is, radio-frequency identification reader/writer is compared by the overlayable range of antenna transceiving radio frequency signal
In handing over all-purpose camera, it is that coverage area is big, 30 meters of fore-and-aft distance or more can be reached.It is stored in radio frequency recognizing electronic label
The related identification information for having vehicle, after radio-frequency identification reader/writer sends corresponding radio frequency command to radio frequency recognizing electronic label,
Related identification information will be fed back to radio-frequency identification reader/writer by radio frequency recognizing electronic label, can by radio-frequency identification reader/writer
To obtain the vehicle identification within the scope of corresponding lane identification, preferred radio frequency band is between 920-925MHz.It is right that vehicle passes through
Road Identification range, including two important nodes are answered, one is admission, that is, enters identification range, the other is appearing on the scene, that is, is left
Identification range.For being obtained by radio-frequency identification reader/writer, when radio-frequency identification reader/writer reads certain in identification range for the first time
When radio frequency recognizing electronic label on a vehicle, the time of acquisition is the entry time of above-mentioned identity vehicle, because vehicle can
Can repeatedly pass through the identification range of some road, but adjacent interval twice is theoretically all relatively long, thus be for the first time
Vehicle leaves counting again after the identification range as a result, the identity read for the first time when i.e. vehicle reenters identification range
Information is referred to as the first time.According to radio frequency recognition principle, if vehicle continues in identification range, radio-frequency identification reader/writer will
The identity information of above-mentioned identity vehicle feedback is constantly read, is terminated until appearing on the scene, therefore can be by being in preset time
The no identity information for reading again corresponding vehicle corresponds to whether identity vehicle appears on the scene to determine, such as if without again in 30 seconds
It is secondary to obtain corresponding identity information, illustrate that the vehicle of above-mentioned identity has appeared on the scene.The corresponding identity vehicle of record enters the identification
The entry time of range, in order to calculate residence time, residence time is intended to indicate that vehicle in the identification range
Residence time, residence time were calculated by entry time.
Step S2, first threshold is set, judge whether residence time of the corresponding identity vehicle in identification range is more than institute
State first threshold.The purpose that first threshold is set be in order to realize judgement vehicle stopped in the identification range thresholding when
Between, first threshold set can according to vehicle normal through the identification range required time as foundation, such as with 20km/h
Speed calculate through time of identification range, it may also be necessary to add rational tolerance time, can directly be arranged first
Threshold value is 1 minute.It should be noted that the dynamic for being also contemplated that first threshold according to different positions adjusts, such as identify model
It is in the alert bayonet of electricity to enclose residing section, and the passage of vehicle is also dispatched by traffic lights, therefore is also contemplated that red light and is caused vehicle
Residence time.It is compared with first threshold by the way that residence time of the identity vehicle in identification range will be corresponded to, to not
Same comparison result makes corresponding operation.
Step S3, it is abnormal behaviour vehicle to the marking of cars that residence time is more than the first threshold.Setting is when resident
When time is more than between first threshold or setting when camped more than or equal to first threshold, illustrate vehicle in identification range at this time
Residence time is longer, is marked as abnormal behaviour vehicle.The abnormal behaviour vehicle of label can be operated further,
Such as can include uniformly on the map corresponding position of screen by abnormal behaviour vehicle.Preferably, when having determined that abnormal behaviour
Vehicle has appeared on the scene, that is, can be the abnormal behaviour car stowage of label in another individual database after leaving identification range
In, it is only used in and is shown on screen at present still in the abnormal behaviour vehicle in identification range.
After vehicle is marked as abnormal behaviour vehicle, it can also do and further identify, not according to abnormal behaviour vehicle
Specific abnormal behaviour type is determined with behavior pattern.Second threshold is set, to the abnormal row within the scope of corresponding road Identification
It is analyzed for vehicle, calculates and do not leave the quantity of abnormal behaviour vehicle in identification range also, when resting in identification range
Vehicle alreadys exceed certain limit, and because when traveling slowly leads to stay longer, you can to illustrate corresponding identification model
Road where enclosing is in congestion status.Vehicle is still in can be with by whether persistently read corresponding vehicle in the identification range
Identity judge that second threshold can be determined according to that can accommodate the limit of vehicle within the scope of corresponding road Identification, i.e. vehicle
The vehicle number that can be at most born when congestion.The quantity for resting on the abnormal behaviour vehicle in identification range is more than second threshold
When, determine that corresponding road is in congestion status, that is, the abnormal behaviour vehicle being in identification range is in congestion status, specifically
Abnormal behaviour is caused because congestion is unable to normal pass, the process of judgement can be real-time, be gathered around to the section of any time
Stifled situation carries out real-time judge.As shown in Fig. 2, specifically, five vehicles of A, B, C, D, E are respectively in different moments admission, earliest one
Vehicle is A vehicles in t1 moment admissions, but from the point of view of the residence time distribution of five vehicles in figure, has been above first threshold, and
The t2 moment is without departing from identification range, it is assumed that second threshold setting is four vehicles, therefore may determine that t2 moment corresponding road
Road is in congestion status.In more embodiments, can also according to the average residence time of all abnormal behaviour vehicles come
Determine the jam level of road, average residence time is longer, and expression jam level is higher.All being averaged for abnormal behaviour vehicle are stayed
It stays the time that can calculate the average residence time of all abnormal behaviour vehicles in identification range, or calculates all vehicles of leaving the theatre
Average residence time, or have both at the same time.
Furthermore it is also possible to separate independent analysis to different tracks, specifically, radio-frequency identification reader/writer be by antenna come
Corresponding identification range is covered, and there are one corresponding antenna, the identification range difference of each antenna in usually each track
A track is covered, is responsible for that a track is identified.Separate computations are carried out to the abnormal behaviour vehicle in different tracks, point
Do not judge whether the quantity of the abnormal behaviour vehicle in each track reaches corresponding threshold value, to determine which track is in congestion
State, which track are in the state that passes unimpeded, and the above embodiment can mainly be applied at the crossing with ring road, sometimes
Ring road congestion and main road passes unimpeded, accuracy can be improved by being performed separately.The equipment such as radar are specifically can be combined with, it is close to wagon flow
Degree, congestion, vehicle speed measurement etc., which are done, further accurately to be identified.
In another specific implementation mode, analyze disobeying parking this abnormal behaviour type.Illegal parking is usual
To stop in the trackside position that Parking permitted, due to Roadside Parking have the characteristics that it is solitary, i.e., usually there is no
Two or more vehicles are carried out while being stopped.Therefore, can be judged by the abnormal behaviour of admission vehicle simultaneously, setting the
Three threshold values, have within same entry time and when only admission marking of cars is abnormal behaviour vehicle, and the abnormal row
It is more than the third threshold value for the residence time of vehicle, determines that the abnormal behaviour vehicle is to disobey parking.Third threshold value is set
Purpose be have in same entry time and only admission marking of cars is abnormal behaviour vehicle, it may be possible to disobey and stop
It causes, but it could also be possible that congestion in road causes, but is compared by analysis it can be found that the case where congestion usual vehicle all can
It is slowly moving, residence time is also limited in identification range, and the separated residence time stopped is longer, therefore the two exists
Prodigious difference.The setting of third threshold value can be according to vehicle under congestion status by average time, it may be necessary to
Increase rational tolerance time, such as can directly be arranged 5 minutes or 10 minutes, it is preferable that can be combined with the congestion of history
Transit time and various influence factors synthesis are judged that third threshold value is usually longer than first threshold.It needs to illustrate
It is not necessarily to be merely to indicated in the vehicle of same time point admission in same entry time, the same time can also be included in
Admission vehicle within the scope of point reasonable error can be regarded as in same entry time, i.e., if the entry time of several vehicles
Difference only several seconds, can also regard as in same entry time.As shown in figure 3, five vehicles of A, B, C, D, E enter in different moments
, and residence time is different, wherein A vehicles are just left the theatre, it is clear that be marked as abnormal behaviour in t1 moment admissions at the t2 moment
Vehicle, and by analysis it can be found that D vehicles are also in t1 moment admissions, but there is no quilts since the residence time of D vehicles is shorter
Labeled as abnormal behaviour vehicle, therefore have within same entry time and only A logos are denoted as abnormal behaviour vehicle, and it is resident when
Between longer have been above third threshold value, it is possible to determine that A vehicles are to disobey parking.
In still another embodiment, to traffic accident vehicle, this abnormal behaviour type is analyzed.The vehicle having a car accident
Caused by being typically two vehicles or more vehicle grazings, mostly occur between front and back vehicle or adjacent lane side-by-side cars, therefore generation vehicle
Distance is closer between the vehicle and vehicle of misfortune.Therefore, third threshold value can be set, and third threshold value is as described above, in same admission
When the marking of cars that time has at least two admissions is abnormal behaviour vehicle, and the residence time of the abnormal behaviour vehicle is same
When be more than third threshold value, determine and traffic accident have occurred between the abnormal behaviour vehicle.Here at least two preferably can only set
Two or three are set, because the vehicle that grazing occurs has three the case where sometimes usually based on two.As described above,
The judgement for introducing third threshold value is exactly to differentiate because being interfered caused by congestion.As shown in figure 4, five vehicles of A, B, C, D, E
In different moments admission, and residence time is different, wherein simultaneously in t1 moment admissions, residence time is all held for A vehicles and D vehicles
Continue the t2 moment, be far longer than first threshold, and other vehicle admissions are not present at the t1 moment, therefore within same entry time
There are A vehicles and D logos to be denoted as abnormal behaviour vehicle, and the residence time of A vehicles and D vehicles is all more than simultaneously third threshold value, determines A vehicles
Traffic accident has occurred between D vehicles.
Fiveth threshold value bigger than third threshold value can also be preferably set, when the 5th threshold value limits the processing of traffic accident vehicle
Between, when traffic accident vehicle to leave threshold range in time in the 5th threshold value, can also regard as disobeying parking.5th threshold is set
Value redefines the abnormal behaviour vehicle when determining that the residence time for the abnormal behaviour vehicle having a car accident is more than five threshold values
For disobey parking.
It should be noted that judging to disobey parking in two kinds of embodiments of traffic accident vehicle, the vehicle of admission can wrap
All tracks in same section are included, are to acquire mutiple antennas when identification range is generated by the corresponding antenna in different tracks
The relevant information of correspondence identity vehicle carry out comprehensive analysis and obtain.In addition, in special application, abnormal behaviour vehicle is judged
It is only in that parking or traffic accident vehicle are disobeyed in identification, then as third threshold value can be arranged with first threshold at this time
's.
In the above-described embodiment, it occurs especially in urban road, even if vehicle, which gets congestion, is generally also in slow
Slowly it passes through, therefore can determine the specific abnormal behaviour type of vehicle well using the above embodiment.Here in fact main
It is determined by analyzing the origin cause of formation of congestion in road, the case where congestion in road occurs to be typically as caused by the stifled point in front, most
Typical is exactly that stifled point has a car accident, and also a kind of is exactly so-called ghost clogging, be because of road vehicle relative saturation,
Disturbance of appearance, such as brake etc. form chain reaction caused by virtual stifled point.And urban road is mostly all rather spacious, and
Split point is more, thus the vehicle of congestion and time also than relatively limited, so less will appear long-time congestion not before situation
Occur, slow speed generally can all be kept to move ahead.
But apply in the scene of highway, it is possible to which the case where needing to consider vehicle long-time congestion is especially saved
During holiday, the vehicle of possible congestion is just directly flame-out to be parked on congested link.But it can be " old by vehicle in identification range
Go out newly into " general trend be inferred to, apparent can will be specifically unlikely to be by way of exclusive method and disobey parking or vehicle
Misfortune vehicle excludes.By analyze and determine, disobey parking and traffic accident vehicle after occurring be for a period of time can not be mobile,
The RSSI of the abnormal behaviour vehicle feedback can be passed through at this time（Received Signal Strength Indicatio, connect
The signal strength of receipts indicates）Value judges the state of vehicle, such as when third threshold value after the abnormal behaviour vehicle admission
In the preset range up and down of punctum, there is the fluctuation of RSSI value, illustrate vehicle in movement, then it is concluded that going out vehicle not
Stop or traffic accident state in disobeying, therefore redefines vehicle and be in congestion status or other special circumstances.
In a preferred embodiment, the 4th threshold value, the abnormal behaviour vehicle admission to the third can also be set
In threshold range, the appearance vehicle number in track where calculating the abnormal behaviour vehicle is less than described in the appearance vehicle number
4th threshold value and place track still have new admission the marking of cars be abnormal behaviour vehicle when, redefine the abnormal behaviour vehicle
Be in congestion status.Because stopping or when traffic accident state to disobey judging the abnormal behaviour vehicle, from admission to third threshold value
In range, the abnormal behaviour vehicle is in identification range, so passing through abnormal behaviour vehicle described in the computing interval
The appearance vehicle number in place track, to determine the traffic status in track, if the appearance vehicle number in place track is more, explanation
At least there are no stagnations for the prevailing state in track, therefore abnormal behaviour vehicle ought to leave identification model in rational third threshold value
It encloses, if the appearance vehicle number in place track is less, is limited here by the 4th threshold value, the 4th threshold value can be according to actually gathering around
Appearance vehicle number under stifled serious conditions refers to specific numerical value, when appearance vehicle number is less than four threshold value, explanation
Congestion in road and its serious, or even there is the case where only import but no export, it just needs to redefine at the abnormal behaviour vehicle at this time
In congestion status, thereby increases and it is possible to which congestion is very serious.But above-mentioned analysis method is built upon in the case that road has congestion,
If it is because when causing appearance vehicle less by vehicle is less on road, will draw the wrong conclusion, therefore also to sentence
It is abnormal behaviour vehicle that whether track where disconnected, which still has the marking of cars of new admission, i.e., after the abnormal behaviour vehicle admission,
Other vehicle admissions can not be normal through identification range, that determines that serious congestion occurs really in corresponding road.Preferably,
Can be combined with directly judging road whether congestion come determine it is separated stop whether identifying correctly with traffic accident vehicle, that is, be computed as described above
It is more than described second in the quantity of the abnormal behaviour vehicle still in the quantity of the abnormal behaviour vehicle in the identification range
When threshold value, determine that corresponding road is in congestion status.
As shown in figure 5, five vehicles of A, B, C, D, E are in different moments admission, and residence time is different, wherein A vehicles and D
Vehicle simultaneously in t1 moment admissions, residence time continues up to the t2 moment, by it is above-mentioned directly judge in the way of, then judging A
Traffic accident has occurred between vehicle and D vehicles, but by further judging to find, the track appearance vehicle where A vehicles or D vehicles is less,
By taking no appearance vehicle as an example, it is clear that it is less than the 4th threshold value, and C vehicles and E vehicles enter after A vehicles and D vehicle admissions in identification range,
By residence time it has also been discovered that there is the phenomenon that delay, therefore illustrate that road is to get congestion, and A vehicles and D logos are remembered
Grazing not occurs because of between for abnormal behaviour vehicle, it may be possible to which but encountering congestion because of coincidence admission simultaneously cannot be normal
Caused by moving ahead.
As shown in fig. 6, road vehicle traffic behavior identifying system schematic diagram in an embodiment of the present invention.Road vehicle is handed over
Current be identifying system includes acquiring unit U1, judging unit U2, marking unit U3, by the corresponding identity vehicle of judgement with it is described
Identification range relevant time response determines the behavior pattern of vehicle pass-through.
Acquiring unit U1 is used to obtain the identity of vehicle within the scope of corresponding road Identification, records corresponding identity vehicle and enters institute
State the entry time of identification range.Acquisition modes are received and dispatched preferably by radio-frequency identification reader/writer by radio-frequency identification reader/writer
Radiofrequency signal is written and read the radio frequency recognizing electronic label in front windshield of vehicle, obtains in radio frequency recognizing electronic label
Indicate the information of vehicle identification.How to determine that corresponding identity vehicle is in identification range, is by radio frequency recognizing electronic label
It is no persistently to read subject to corresponding identity information, time as the entry time to read corresponding vehicle identification for the first time, no
The last time read access time before corresponding vehicle identification can be read as the time for competiton, come greatly by admission and the case where appearance
Body judges behavior pattern of the vehicle in identification range.
Whether judging unit U2 judges residence time of the corresponding identity vehicle in identification range for first threshold to be arranged
More than the first threshold.First threshold normal through the identification range required time can be foundation according to vehicle, corresponding
If identification range be in the crossings such as traffic lights, the setting of first threshold is it is also contemplated that the time that red light waits for.First threshold
Setting be that will be distinguished with the vehicle of abnormal behaviour in identification range, i.e., to differentiate the vehicle of normal pass
Find out the vehicle of the stay longer in identification range.For example, certain vehicles have only just passed through identification model within 2 seconds
Enclose, illustrate that it belongs to the vehicle of normal pass, if certain vehicles by identification range need 2 minutes, considerably beyond it is normal when
Between, i.e. it is certain to illustrate that vehicle pass-through there is a problem of for first threshold.Residence time be since after corresponding identity vehicle admission
Timing is until corresponding identity vehicle leaves identification range, and when vehicle is in identification range, residence time can be with the time
Passage constantly increases.
Marking unit U3 is used to be abnormal behaviour vehicle to the marking of cars that residence time is more than the first threshold.Pass through
It is compared with first threshold, is abnormal behaviour vehicle by the marking of cars that residence time is more than first threshold.As described above, mark
The abnormal behaviour vehicle of note can be directly displayed on the map of screen, or do further identification to abnormal behaviour vehicle.It is excellent
Second threshold is arranged in selection of land, marking unit U3, and second threshold is for indicating a kind of threshold value of vehicle number, specifically according to correspondence
Road can vehicle limit determine.Calculate number of the corresponding road still in the abnormal behaviour vehicle in the identification range
Amount determines that corresponding road is in congestion status when the quantity of the abnormal behaviour vehicle is more than the second threshold.It determines
Road congestion is typically a real-time process, and the above embodiment needs to analyze sometime, on road in identification range
The quantity of abnormal behaviour vehicle judge congestion in road situation, when sometime some abnormal behaviour vehicle has been moved off identification
Range, it should determine not in the quantity of statistics.
Third threshold value is arranged in marking unit U3, and the standard of congestion transit time can be set by third threshold value.Pass through
Three threshold values, can have within same entry time and when only admission marking of cars is abnormal behaviour vehicle, and described different
The residence time of Chang Hangwei vehicles is more than the third threshold value, determines that the abnormal behaviour vehicle is to disobey parking.Or same
When the marking of cars that there is at least two admissions in one entry time is abnormal behaviour vehicle, and the abnormal behaviour vehicle is stayed
It stays the time while being more than third threshold value, determine and traffic accident has occurred between the abnormal behaviour vehicle.Utilize separated parking or traffic accident
Separated parking or traffic accident vehicle are distinguished by the special relationship between vehicle and entry time.It is described in addition it can pass through
The trend of the RSSI value of abnormal behaviour vehicle feedback or judgement " go out always newly into " is excessively serious and cause to ensure to exclude congestion
Judge that above-mentioned abnormal behaviour type has that mistake, relevant embodiment can also be referring in particular to roads by entry time
