Fig. 7 is that the deck vehicle among the expression embodiment is examined the threshold calculations section of car device according to density-speed in the traffic flow model, vehicle flowrate-speed curve diagram.As shown in Figure 7, traffic flow analysis and model are set up following description:
The state of road traffic flow can be differentiated by research traffic flow three elements.The traffic flow load of machinery systems of magnitude of traffic flow reflection road; The service level that speed reflection road can provide; What density reflected is the degrees of freedom that vehicle travels at road.
Traffic flow three elements relation is suc as formula (1).
Q＝V·K (1)
Wherein Q is the magnitude of traffic flow (veh/h); V is section mean speed (km/h); K is vehicle density (veh/km).
Analyze the relation of K-V, then derive the Q-V relation by formula (1).
Generally speaking, when the vehicle fleet size before and after the driving vehicle increased, the driver must reduce the speed of a motor vehicle, illustrated that speed was on a declining curve when traffic density raise.Suppose that speed-density model is linear model, namely adopt Greenshields linear relationship model, suc as formula (2):

Formula (4) fundamental relation figure as shown in Figure 7.
By formula (3), (4) and Fig. 7 as can be known, when traffic flow density leveled off to zero (volume of traffic is very little), vehicle average velocity leveled off to the average velocity V of Free-flow
f, vehicle flowrate levels off to zero simultaneously.When traffic flow density levels off to maximal value, namely level off to jam density K
jThe time, vehicle average velocity levels off to zero, and vehicle flowrate levels off to zero again simultaneously.
Therefore, calculate the rational theoretical average velocity of vehicle according to vehicle flowrate, i.e. speed of a motor vehicle threshold value, and actual average speed and the speed of a motor vehicle threshold value of this vehicle compared, if the actual average speed of vehicle is higher than the speed of a motor vehicle threshold value of vehicle, can judge that then this vehicle is the deck vehicle.
The below describes the testing process of pick-up unit 11 of the present invention.
Fig. 8 is the process flow diagram that the deck vehicle detection apparatus in the expression present embodiment detects the deck vehicle.
Wherein data store 112 adopts the mode of dictionaries mapping to store to comprise the number-plate number, the car plate type, the bayonet socket sign of process, through the time mark of bayonet socket, the data such as body color.
Adjacent bayonet socket retrieve stored section 113 also adopts the mode retrieve data of dictionary mapping, at first use the number-plate number in the vehicles data to retrieve as key, guarantee to view fast the vehicle of a certain number-plate number in the data store through the current data of other bayonet sockets, simultaneously take the identification sets cooperation of the first bayonet socket and the second bayonet socket for as key word, set up all and tabulate through the vehicle data of the second bayonet socket again after through the first bayonet socket and this tabulation is stored.
Buffer zone and Department of Communication Force set up complete after, pick-up unit begins to wait for that front end bayonet socket data acquisition equipment sends comprises the number-plate number, elapsed time, bayonet socket sign, car plate type, the vehicles data (step 02) of vehicle color.
After Department of Communication Force 111 received vehicles data, data store 112 was stored these current data.(step 03).
Adjacent bayonet socket retrieval stores, 113 retrieve data storage part 112 as key word with the number-plate number of the vehicle of process, if in data store 112, there are not the current data of the adjacent traffic block port of the identical number-plate number, these current data are written in the data store 112, then continue to wait for next vehicles data (step 04).Sequence number is 1 record as shown in Figure 4, when the number-plate number for the vehicle of " Shanghai A12345 " when being designated 1001 bayonet socket, whether inspection exists the number-plate number in data store be the vehicles data of " Shanghai A12345 ", because do not find the data that meet, be the vehicles data data writing storage part of " Shanghai A12345 " with the number-plate number.
If there are the current data at adjacent traffic block port of an identical number-plate number in data store 112, adjacent bayonet socket retrieval reservoir 113 is taken out (step 05) with original current data from data store.Sequence number is 1014 record as shown in Figure 4, when the number-plate number for the vehicle of " Shanghai A12345 " when being designated 1002 bayonet socket, whether inspection exists the number-plate number through the bayonet socket adjacent with the bayonet socket that is designated 1002 in data store be the vehicles data of " Shanghai A12345 ", because in data store 112, find this vehicle through the current data of 1001 bayonet sockets, this information is taken out from data store 112, obtain this vehicle by the current data of 1001 bayonet sockets and 1002 bayonet sockets.
The bayonet socket sign of process is as the first bayonet socket in the original current data of adjacent bayonet socket retrieve stored section's 113 extractions, bayonet socket according to process in the current current data identifies as the second bayonet socket again, according to two bayonet socket signs, the data of will passing through are set up data list, and what preserve in this data list is that all are through the current data (step 06) of this first bayonet socket and the second bayonet socket.To cross car information according to the bayonet socket of process sign 1001/1002 from two vehicles that previous step obtains, be stored in the adjacent bayonet socket retrieve stored section 113 as shown in Figure 5 article one data list.
The first bayonet socket sign and the second bayonet socket sign according to current data read free travel speed V between bayonet socket from adjacent bayonet socket parameter list 114
f=78.1, the jam density K between bayonet socket
j=72.8 and bayonet socket between apart from L=3.49,
Speed of a motor vehicle threshold calculations section 115 is according to V
f, K
j, Q utilizes formula 4 to calculate average passage rate threshold value V
t=20.99 or V
t=57.01.Because consider the factors such as vehicle may stop in the process of moving, the V of little speed
tNumerical value can be ignored, and chooses maximum V at this
t=57.01 are used as average passage rate threshold value (step 07).
The elapsed time of original current data and current current data is labeled as t1=2011-10-1513:14:27 and t2=2011-10-1513:17:19, and distance is L=3.49 between bayonet socket, utilizes formula
Calculating the average speed of vehicle between bayonet socket is V
a=73.04, judging part 116 is with vehicle average speed V
a=73.04 and average passage rate threshold value V
t=57.01 compare to judge whether vehicle is the deck vehicle, if V
a＞Vt illustrate that vehicle is the deck vehicle, otherwise vehicle is normal vehicle (step 08).Because 73.04＞57.01, therefore can judge number plate of vehicle as the automobile storage of " Shanghai A12345 " in the deck behavior.
If vehicle is the deck vehicle, memory module 117 is informed in the result of determination input, write stored data base and inform that the user finds deck vehicle (step 9).
Judge after the end that current current data are written in the data store 112, and original current data are deleted from data store 112.Simultaneously with the stale data deletion (step 10) that surpasses the unit interval in the buffer zone.
Adopt the traffic flow model detection technique, owing to determined the relation between vehicle average velocity and the traffic flow, the standard of judging the deck vehicle no longer is the fixed speed threshold value, and take full advantage of the result of statistics, dynamic change according to vehicle flowrate, determine that dynamic threshold speed judges, thereby greatly reduce the impact that different road conditions cause judgement.
When vehicle flowrate is smaller, may be because condition of road surface be very good, the reason that vehicle density is little, and this time vehicle speed can improve, therefore need to improve the criterion of the speed of a motor vehicle.When vehicle flowrate begins to increase, illustrate that vehicle density becomes greatly gradually, vehicle can reduce the speed of a motor vehicle, therefore need to reduce the criterion of the speed of a motor vehicle.By the relation of the speed of a motor vehicle and traffic flow in the use traffic flow model, can dynamically adjust speed of a motor vehicle judgment threshold according to the real road situation.Reduced the probability of happening of failing to report and report by mistake situation.
