Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Embodiment one
Fig. 1 shows the flow chart of the traffic intelligent command and control method of the offer of the embodiment of the present invention one, and Fig. 2 shows should
A kind of schematic diagram of the scene of crossroad applied by method.
As shown in Fig. 2, the crossing of four direction is located on orthogonal two trunnion axis in the crossroad, there is no harm in
It is defined as X-axis and Y-axis, as shown in Figure 2, wherein being located at the positive axis of X-axis to the crossing 203 that the direction C is advanced, to the direction A row
Into crossing 201 be located at the negative semiaxis of X-axis, and be located at the positive axis of Y-axis to the crossing 204 that the direction D is advanced, to the traveling of the direction B
Crossing 202 be located at the negative semiaxis of Y-axis.
Step S101: the master for calculating all directions crossing of current intersection preferentially measures, and the master preferentially measures by enter
The vehicle fleet size at direction crossing determines.
Such as in Fig. 2,202 right channel of the direction B crossing is divided into Through Lane bx2, left turn lane bx1 and right-hand bend vehicle
Road bx3, similarly, 201 right-hand lane of the direction A crossing are also classified into Through Lane ax2, left turn lane ax1 and right-turn lane
ax3；203 right-hand lane of the direction C crossing is divided into Through Lane cx2, left turn lane cx1 and right-turn lane cx3；The direction D road
204 right-hand lanes of mouth are divided into Through Lane dx2, left turn lane dx1 and right-turn lane dx3.
The vehicle that enter the direction D crossing 204 includes: the vehicle for driving into the Through Lane bx2 at the direction B crossing 202, drives into
Vehicle in the right-turn lane cx3 at the direction C crossing 203 drives into vehicle in the left turn lane ax1 at the direction A crossing 201.
Under the premise of not considering vehicle priority, the master at the direction D crossing preferentially measures the vehicle that can be defined as the lane bx2
The vehicle fleet size in the lane vehicle fleet size+ax1 in the lane quantity+cx3.
In the embodiment of another replacement, it may be considered that different types of vehicle is arranged different in main preferential amount calculates
Weight, such as using 110,120,119 police cars as A1 class vehicle, using social common vehicle as A2 class vehicle, by public friendship
Be open to traffic a conduct A3 class vehicle, and haulage vehicle is as A4 class vehicle.Wherein weight is considered that these vehicles need in practice
Will by priority be configured, such as the weight of A1 vehicle is set as 10t, and the weight of A2 class vehicle is set as 1t, A3 class
The weight of vehicle is set as 5t, and the weight of A4 class vehicle is set as 7t.In this way, the vehicle fleet size in each lane is by every class
The quantity of vehicle is summed again multiplied by the weight of such vehicle, and then the vehicle that enter the direction D crossing 204 being calculated
Quantity be also to be obtained with reference to the weight calculation of various types of vehicles.In practice, t here represents standard, Ke Yigen
Flexible setting is carried out according to the actual demand of system.
The master that the direction A crossing 201 can similarly be calculated preferentially measures, and the master at the direction B crossing 202 preferentially measures and the direction C crossing
203 master preferentially measures.It can be determined with reference to the vehicles number that enter all directions crossing as follows:
The vehicle that enter the direction A crossing 201 includes: the vehicle for driving into the Through Lane cx2 at the direction C crossing 203, drives into
The vehicle of the right-turn lane dx3 at the direction D crossing 204 drives into the vehicle of the left turn lane bx1 at the direction B crossing 202；
The vehicle that enter the direction B crossing 202 includes: the vehicle for driving into the Through Lane dx2 at the direction D crossing 204, drives into
The vehicle of the right-turn lane ax3 at the direction A crossing 201, drive into the direction C crossing 203 left turn lane cx1 vehicle.
It can be seen that in the present embodiment, calculate to enter direction crossing vehicle fleet size be by current intersection its
It is calculated in his crossing by the queuing vehicle quantity that Through Lane, left turn lane and right-turn lane will drive into the direction crossing
It obtains.
Step S102: the sum that the master at multiple crossings of same straight trip route preferentially measures is calculated, as the straight trip route
Master preferentially measure.
Still by taking Fig. 2 as an example, the direction A crossing 201 and the direction C crossing 203 are on same straight trip route, because driving into the side A
Crossroad will be passed through to the vehicle of the Through Lane ax2 at crossing 201, is standard in Fig. 2 into the direction C crossing 203
Crossroad, road belonging to four crossings form perpendicular two lines.Therefore in the example in figure 2, keep straight in same
Two crossings on route are also point-blank.
Step S103: preferentially measuring according to the master of all straight trip routes, preferentially preferentially measures biggish straight trip route sending to main
Vehicle passes through signal.
By taking Fig. 2 as an example, the direction A crossing 201, the direction B crossing 202, the master at the direction C crossing 203 and the direction D crossing 204 are excellent
It first measures and is denoted as A master, B master, C master, D master respectively, therefore in identical straight trip route where the direction A crossing 201 and the direction C crossing 203
On master preferentially measure as A master+C master, it is preferential in the master where the direction B crossing 202 and the direction D crossing 204 on identical straight trip route
Amount is B master+D master.As (A master+C master) > (B master+D master), the direction prior-release A crossing 201 and the direction C crossing 203, in reality
First the straight trip green light at the direction A crossing 201 and the direction C crossing 203 can be lighted in border.
Identical straight trip route is preferentially measured for master, the auxiliary preferential amount of the straight trip route can be calculated, which is
By what is determined by the quantity of the pedestrian of identical straight trip route direction.It in practice, can be on the pavement at each crossing
Camera is arranged in both ends, the number for being waited by video capture identification technology calculating at pavement both ends, and pavement two
The number addition that end waits, which can be obtained, will pass through identical straight trip route direction by the quantity of the pedestrian on the pavement
The quantity of the pedestrian on pavement is added, and can be obtained will be by the quantity of the pedestrian in the direct route direction.
Still by taking Fig. 2 as an example, it is assumed where (A master+C master)=(B master+D master), the i.e. direction A crossing 201 and the direction C crossing 203
Master on identical straight trip route preferentially measures equal to the master on straight trip route identical where the direction B crossing 202 and the direction D crossing 204
Preferential amount then needs to consider the auxiliary preferential amount of the two straight trip routes.With 203 place phase of the direction A crossing 201 and the direction C crossing
The identical pavement in direction with straight trip route is pavement 206 and pavement 208, and wherein pavement 206 is across the direction B crossing
202, pavement 208 is across the direction D crossing 204.It therefore will be by identical as the direction A crossing 201 and the direction C 203 places of crossing
Direction pedestrian's quantity of straight trip route is to pass through the sum of the quantity of the pedestrian on pavement 206 and pavement 208.
Similarly, to pass through pedestrian's number in the direction of straight trip route identical as the direction B crossing 202 and the direction D 204 places of crossing
Amount are as follows: to pass through the quantity of the pedestrian on pavement 205 and pavement 207.Wherein, pavement 205 is across the direction A crossing 201
Pavement, pavement 207 be across the direction C crossing 203 pavement.
After the auxiliary preferential amount for calculating the straight trip route preferentially measured with identical master, identical straight trip is preferentially measured main
In route, preferentially to it is auxiliary preferentially measure biggish straight trip route and issue vehicle pass through signal.
By taking Fig. 2 as an example, if will be by the sum of the quantity of the pedestrian on pavement 205 and pavement 207 greater than people to be passed through
The sum of pedestrian's quantity on trade 206 and pavement 208 then can be determined that the direction B crossing 202 and 204 place of the direction D crossing are identical
Auxiliary preferential amount where the auxiliary preferential amount of straight trip route is greater than the direction A crossing 201 and the direction C crossing 203 on identical straight trip route,
Therefore vehicle preferentially is issued to identical straight trip route where the direction B crossing 202 and the direction D crossing 204 pass through signal.
Certainly, it in the scene for passing through signal with independent pedestrian, while sending vehicle passes through signal, should also send out
The signal that the pedestrian of the same direction passes through out.
In the present embodiment, issue vehicle by way of signal can there are many kinds of, such as referred to by traffic lights
Show that vehicle passes through.In by the way of traffic lights, a kind of common practice is that the bright expression of red light stops, and green light lights table
Show and pass through, the reason of this way, is that red light is passed through apart from farther, therefore by stop signal be set as it is red in practice more
Safety, but the range of the present embodiment is not precluded and carries out the color for indicating the signal lamp for passing through and stopping in certain specific occasions
Replacement.
Embodiment two
The vehicle for only only accounting for entering certain crossings in main preferential amount is calculated in the above-described embodiment, and in reality
In, if encountering vehicle driving situation violating the regulations, it is contemplated that the pressure violating the regulations caused by the traffic in certain direction, and then increase
The master in this direction preferentially measures.
Based on considerations above, the present embodiment provides a kind of traffic intelligent command and control methods, as shown in figure 3, this method
Include the following steps:
Step S301: the master for calculating all directions crossing of current intersection preferentially measures, which preferentially measures by enter this
The vehicles number at direction crossing and the quantity that enter vehicles running red light in the vehicle at the crossing determine.
By taking the crossroad scene shown in Fig. 4 as an example, wherein label and identical part in Fig. 2 are identical structure, this
In repeat no more, difference is only that: each crossing be provided opposite to monitor and calculate vehicles running red light quantity monitoring device,
Such as it can be the equipment such as camera.In addition, there is the vehicle violating the regulations to make a dash across the red light in the vehicle at the direction D to be entered crossing 204
401, which has been in the region of crossroad.
In the present embodiment, the master at all directions crossing preferentially measure in increase the quantity of vehicles running red light, be with Fig. 4
Example, the master at the direction D crossing preferentially measures D master can be with is defined as: the vehicle fleet size+ax1 in the lane vehicle fleet size+cx3 in the lane bx2
The vehicle to make a dash across the red light at the crossing over there (i.e. the direction B crossing 202) that the place vehicle fleet size+D monitoring device in lane monitors
Quantity, and the vehicle that crossing is made a dash across the red light over there also belong to will enter the direction the D crossing 204 vehicle.And so on can be with
Calculate A master, B master, C master.
Certainly during calculating vehicle fleet size, it may be considered that different types of vehicle is arranged different weights, example
Such as using 110,120,119 police cars as A1 class vehicle, using social common vehicle as A2 class vehicle, using public transportation vehicle as
A3 class vehicle, haulage vehicle is as A4 class vehicle.Wherein weight be considered that these vehicles need in practice by it is excellent
First grade is configured, such as the weight of A1 vehicle is set as 10t, and the weight of A2 class vehicle is set as 1t, the weight of A3 class vehicle
It is set as 5t, the weight of A4 class vehicle is set as 7t.In this way, the vehicle fleet size in each lane is by the quantity of every class vehicle
It sums again multiplied by the weight of such vehicle.In a preferred embodiment, to enter the crossing what is monitored
Vehicle in vehicles running red light quantity computation method in, it is also contemplated that carrying out weighted sum after the weight of all types of vehicles.
Step S302: the sum that the master at two crossings of same straight trip route preferentially measures is calculated, as the straight trip route
Master preferentially measure.
The implementation of step S302 is identical as the implementation of step S102 in embodiment one in the present embodiment, here
Repeat no more, only here calculated master preferentially measure needs accounted for referring to the calculation method in step S301.
Step S303: preferentially measuring according to the master of all straight trip routes, preferentially preferentially measures biggish straight trip route sending to main
Vehicle passes through signal.
The implementation of step S303 is identical as the implementation of step S103 in embodiment one in the present embodiment, here
Repeat no more, only here calculated master preferentially measure needs accounted for referring to the calculation method in step S301.
What needs to be explained here is that the field in Fig. 2 and Fig. 4 for being illustrated in above-described embodiment one and embodiment two
Scape is the crossroad of standard, i.e., the road at each crossing forms "+" shape, and in actual road environment, each road
Angle may not be stringent 90 degree, such as can be X-shaped, or the road where two crossings of even face is not one
On straight line, but said circumstances can using the scheme in above-described embodiment one and embodiment two, because in these scenes,
Condition of two crossings on same straight trip straight line is all had, i.e., the vehicle that Through Lane is driven out to from the two crossings all can be into
Enter other side crossing, although road belonging to the two crossings itself is not on same geometry straight line.
Using the scheme in above-described embodiment one and embodiment two when carrying out traffic guidance control, instantly property compared with
By force, only consider the situation of current crossroad, instantaneity is stronger, judges that speed is fast, and the realization of this method can not depend on
In network, high stability.
Embodiment three
As mentioned previously, the case where scheme in embodiment one and embodiment two only considers current crossroad, in time
Property it is stronger, system judges that speed is fast, and high stability, but for need macroscopic view promoted circulation of traffic when, use
This mode shows slightly insufficient.The present embodiment proposes a kind of improved embodiment after in view of the above problem, as shown in figure 5,
The traffic intelligent command and control method provided in the present embodiment includes the following steps:
Step S501: the vehicle imported from each Adjacent Intersections of current intersection to the current intersection direction is calculated
Quantity；
It is that application scenarios are illustrated using traffic route figure shown in Fig. 6, Fig. 7 is the part in Fig. 6 at intersection 603
Detail view.The traffic control problems at intersection 603 are considered now, therefore intersection 603 is exactly the current intersection in this example.
The adjacent intersection in this current intersection is intersection 601, intersection 608, intersection 606 and intersection 607.
There are four crossings for tool in intersection 603, are denoted as crossing 6031,6032,6033 and 6034 respectively.
The vehicle imported from adjacent intersection 601 to 603 direction of intersection by the right-hand lane at crossing 6031 into
Row is lined up, and the vehicle imported from adjacent intersection 608 to 603 direction of intersection is by the right-hand lane progress at crossing 6034
It is lined up, the vehicle imported from adjacent intersection 606 to 603 direction of intersection arranges the right-hand lane at crossing 6033
Team, the vehicle imported from adjacent intersection 607 to 603 direction of intersection will be lined up at crossing 6032.
Step S502: the master for calculating all directions crossing of current intersection preferentially measures, and the master at direction crossing preferentially measures
Quantity by being imported into the vehicle at other crossings being on identical straight trip route with direction crossing from Adjacent Intersections determines.
It can be seen that when the master in the present embodiment at all directions crossing of the current intersection of calculating preferentially measures, substantially
It is still to be determined by the vehicle fleet size at direction crossing to be entered, only unlike embodiment one and embodiment two,
It is to be imported into from Adjacent Intersections and be in identical straight with the direction crossing when calculating the vehicle fleet size that enter direction crossing
What the quantity of the vehicle at other crossings on walking along the street line was calculated.
Still by taking Fig. 6 as an example, the master at four crossings of current intersection 603 preferentially measures and can be denoted as respectively: crossing 6031
The preferential amount of master is main for 6031, and it is 6032 main that the master at crossing 6032, which preferentially measures, and the master at crossing 6033 preferentially measures, crossing main for 6033
6034 master preferentially measures main for 6034.
Crossing 6032 and crossing 6034 are on same straight trip route, and crossing 6031 and crossing 6033 are in same straight trip route
On.
The master at crossing 6031 preferentially measures 6031 masters and can be defined as being imported into current intersection 603 from Adjacent Intersections 606
Crossing 6033 at vehicle quantity；
The master at crossing 6032 preferentially measures 6032 masters and can be defined as being imported into current intersection 603 from Adjacent Intersections 608
Crossing 6034 at vehicle quantity；
The master at crossing 6033 preferentially measures 6033 masters and can be defined as being imported into current intersection 603 from Adjacent Intersections 601
Crossing 6031 at vehicle quantity；
The master at crossing 6034 preferentially measures 6034 masters and can be defined as being imported into current intersection 603 from Adjacent Intersections 607
Crossing 6032 at vehicle quantity.
The quantity for the vehicle that above-mentioned each Adjacent Intersections of calculating are imported to current intersection direction can be by above-mentioned each
Monitoring device at a Adjacent Intersections is realized, to calculate the crossing for being imported into current intersection 603 from Adjacent Intersections 601
For the quantity of vehicle at 6031: at intersection 601, calculating and sail to come at the Adjacent Intersections of the intersection 601 and drive into
To the sum of the vehicle in 603 direction of intersection, as from the crossing 6031 that Adjacent Intersections 601 are imported into current intersection 603
Vehicle quantity, and sail the vehicle for coming and driving into 603 direction of intersection from the Adjacent Intersections of intersection 601 and include:
It keeps straight on from intersection 605 by intersection 601 and drives towards the vehicle of intersection 603, turns left from intersection 602 by intersection 601
The curved vehicle for driving towards intersection 603 and the vehicle for driving towards intersection 603 by the right-hand bend of intersection 601 from intersection 604.
It can thus be seen that in the present embodiment, calculate each crossing master preferentially measure during, referring also to adjacent
The wagon flow situation of intersection.
Certainly, during calculating vehicle fleet size, it is also contemplated that different weights, example is arranged in different types of vehicle
Such as using 110,120,119 police cars as A1 class vehicle, using social common vehicle as A2 class vehicle, using public transportation vehicle as
A3 class vehicle, haulage vehicle is as A4 class vehicle.Wherein weight be considered that these vehicles need in practice by it is excellent
First grade is configured, such as the weight of A1 vehicle is set as 10t, and the weight of A2 class vehicle is set as 1t, the weight of A3 class vehicle
It is set as 5t, the weight of A4 class vehicle is set as 7t.In this way, calculating from each Adjacent Intersections of current intersection to deserving
When the quantity for the vehicle that preceding intersection direction imports, it can be weighted summation according to the affiliated type of vehicle and obtain the number of vehicle
Amount.
Step S503: the sum that the master at two crossings of same straight trip route preferentially measures is calculated, as the straight trip route
Master preferentially measure.
By taking Fig. 6 as an example, in current intersection 603, on same straight trip route, this is straight for crossing 6031 and crossing 6033
The master of walking along the street line preferentially measures main for 6031 main+6033；Crossing 6032 and crossing 6034 are kept straight on route in same, the straight trip
The master of route preferentially measures main for 6032 main+6034.
Step S504: preferentially measuring according to the master of all straight trip routes, preferentially preferentially measures biggish straight trip route sending to main
Vehicle passes through signal.
By taking Fig. 6 as an example, it is assumed that (6031 main+6033 is main) > (6032 main+6034 is main), then preferentially to crossing 6031 and crossing
Same straight trip route where 6033 issues vehicle communication signal, realizes prior-release crossing 6031 and crossing 6033.In reality
First the straight trip green light at crossing 6031 and crossing 6033 can be lighted in border.
Identical route is preferentially measured for master, the auxiliary preferential amount of the straight trip route can be calculated, which is by wanting
It is determined by the quantity of the pedestrian of identical straight trip route direction.It in practice, can be at the both ends on the pavement at each crossing
Camera is set, the number for being waited by video capture identification technology calculating at pavement both ends, and pavement both ends etc.
To number addition can be obtained will by the quantity of the pedestrian on the pavement, will pass through it is identical straight trip route direction people's row
The quantity of the pedestrian in road is added, and can be obtained will be by the quantity of the pedestrian of the straight trip route direction.
Still by taking Fig. 6 as an example, it is assumed that (6031 main+6033 is main)=(6032 main+6034 is main), i.e. crossing 6031 and crossing 6033
The master of the same straight trip route at place preferentially measures the master equal to the same straight trip route where crossing 6032 and crossing 6034
Preferential amount then needs to consider the auxiliary preferential amount in the two straight trip routes.As shown in fig. 7, with 6033 institute of crossing 6031 and crossing
Same straight trip the route same direction pavement be pavement 6036 and pavement 6038, wherein pavement 6036 across
Cross crossing 6032, pavement 6038 is across crossing 6034.With same straight trip route phase Tongfang where crossing 6032 and crossing 6034
To pavement be pavement 6035 and 6037, wherein pavement 6035 is across crossing 6031, and pavement 6037 is across crossing
6033。
So the auxiliary preferential amount of the same straight trip route where crossing 6031 and crossing 6033 can define in Fig. 7
To be kept straight on by the quantity of the pedestrian on pavement 6036 and pavement 6038, the same where crossing 6032 and crossing 6034
The auxiliary preferential amount of route can be defined as will be by the quantity of the pedestrian on pavement 6035 and pavement 6037.
After the auxiliary preferential amount for calculating the straight trip route preferentially measured with identical master, identical straight trip road is preferentially measured in master
In line, preferentially to it is auxiliary preferentially measure biggish straight trip route and issue vehicle pass through signal.
In the present embodiment, by the judgement of network type, change lamp is carried out in advance, so that cart smoothness is logical, small wagon flow gives way,
The fluency for promoting traffic to macroscopic view of overall importance has larger improvement.
But the scheme in the present embodiment is more demanding to internet arithmetic speed, in order to improve the stabilization of whole system
Property, it in a preferred embodiment, can be executed when unexpected suspension using the traffic control process of default, example
Such as lamp scheme is jumped using the traffic lights of default timing.
Example IV
The present embodiment accordingly provides a kind of traffic intelligent command and control system, as shown in figure 8, the system includes:
Crossing master preferentially measures computing module 801, preferentially measures for calculating the master at all directions crossing of current intersection, institute
Main preferential amount is stated to be determined by the vehicle fleet size at direction crossing to be entered；
Straight trip route master preferentially measures computing module 802, for calculating the master at multiple crossings on same straight trip route
The sum preferentially measured, the master as the straight trip route preferentially measure；
Signal control module 803 is preferentially preferentially measured to master biggish straight for preferentially being measured according to the master of the straight trip route
Walking along the street line issues vehicle and passes through signal.
