The process of the method for canalization, the device which can be canalized with crossing inlet track data execute, which can be located at such as Fig. 1
In shown server 100, it is also possible to the server 100.
As shown in Fig. 2, the process specifically includes:
Step 201, section vehicle number, the section flat within a preset time interval in each lane in crossing inlet road is obtained
Equal vehicle commander and maximum queue length.
Section vehicle number, the section within a preset time interval in each lane in crossing inlet road in the embodiment of the present invention
Average vehicle commander and maximum queue length are obtained by multiple target radar.Multiple target radar detector is laid in intersection exit
On road Traffic signal post, the traffic flow parameter of reversed entrance driveway is detected.Multiple target radar usually can detect two kinds of traffic flow
Data, one is section traffic flow datas, including flow, average speed, time headway etc.；Another kind is regional traffic fluxion
According to, including queue length, stop frequency, delay time at stop etc..There is corresponding detection section and detection in multiple target radar detector
Region, as shown in figure 3, detection section for detecting section traffic flow data, usually apart from 30 meters of stop line of section, detects
Region is used for detection zone traffic flow data, usually to the region at 200 meters of in upstream since stop line.The inspection of multiple target radar
The telecommunication flow information that can distinguish lane grade is surveyed, lane is from center line of road to both sides of the road serial number.
Multiple target radar detector performance has differences, and there are multiple values such as 30 meters, 50 meters in the position for detecting section, detection
The range in region meter is differed from 50 meters to 200.The embodiment of the present invention is based on the lane grade magnitude of traffic flow and vehicle queue data, proposes
Problem identification method is canalized in entrance driveway.Detection section is set to guided vehicle road solid line beginning, away from 30 meters of the stop line shortest distance,
Detection section, which is arranged such, more can accurately count vehicle flow of the practical divided lane by intersection.Detection zone position exists
At 200 meters of stop line, utmostly to measure the queue length in lane.The embodiment of the present invention requires multiple target detections of radar
Device can cover entrance driveway whole lane, it is assumed that specific crossing inlet road lane quantity is n, then to the right from center line of road
Lane number is sequentially 1,2,3 by (along direction of traffic) ..., n.
Mainly include two kinds due to influencing intersection efficiency: first is that unreasonable signal timing dial, second is that not
Reasonable entrance driveway canalization.And the present invention identifies that problem canalization entrance driveway influences to hand on condition that intersection signal timing has optimized
The main cause of prong traffic efficiency is unreasonable crossing inlet road canalization.
In order to identify problem intersection channelizing, the embodiment of the present invention is such as given a definition:
Using single crossing entrance driveway as minimum detection space cell；
Minimum time unit is counted using 5 minutes as traffic flow parameter, 24 hours one day were divided between 288 times
Every ti (time interval), tijFor j-th of time interval, j=1,2,3 ..., 288；
LaneiFor i-th lane numbered from center line of road to both sides of the road, i=1,2,3 ..., n are total to have n item
Lane.
It is the section vehicle number that i-th lane detections of radar in j-th of time interval arrives.
It is that the section in i-th lane detections of radar road in j-th of time interval is averaged vehicle commander (average
vehicle length)。
It is the maximum queue length (maximum that i-th lane detections of radar in j-th of time interval arrives
queue length)。
Step 202, it is averaged vehicle commander, is determined each according to the section vehicle number, the maximum queue length and the section
The pressure share rate in lane.
It in the pressure share rate for determining each lane, is mainly averaged vehicle commander, is determined according to maximum queue length and section
Maximum queuing vehicle number in each prefixed time interval determines each vehicle then according to maximum queuing vehicle number and section vehicle number
The pressure share rate in road.
Lane can not provide enough traffic capacitys, and vehicle is caused to stop before stop line, and bear the pressure being lined up.?
Under the conditions of ideal, the queue pressure in all directions and each lane is equal.If the vehicle of some direction of traffic distribution
Road number is very few, is unable to satisfy its transport need, then the lane queue pressure that will lead to this direction of traffic is excessive, cause frequently and
Serious vehicle parking is lined up.
Maximum queuing vehicle number in each time interval isRepresent the pressure of the i-th lane receiving, calculation formula
(1) are as follows:
Accordingly, it can get the pressure share rate (share ratio) in each lane in each time intervalMeasure i-th
Lane vehicle queue degree, calculation formula (2) are as follows:
Wherein,Represent i-th lane transport need whole in j-th of time interval.The pressure in lane
Power share rate is bigger, it is more to represent the vehicle being lined up on lane, that is, distribute enough vehicles without the affiliated direction in lane thus
Road causes queue pressure to become larger.
Step 203, according to the pressure share rate in each lane, the standard of the pressure share rate in the crossing inlet road
Difference and share rate imbalance threshold, determine the first crossing inlet road.
In embodiments of the present invention, which is the crossing inlet road that there are problems that canalization, wherein
Share rate imbalance threshold may include the share rate imbalance threshold of multiple time cycles, which can empirically set
It sets, such as can be 1 day, 1 month, 1 season, 1 year etc., the embodiment of the present invention is not specifically limited in this embodiment.
For example, reasonable entrance driveway be canalized under the conditions of, the pressure share rate in each lane be it is equal, i.e.,It is canalized without reasonable lane, causes the transport need in specific lane to be unable to get full
Foot, causes specific lane to generate more vehicle queue, it is unbalance to will lead to lane share rate.Therefore, identification problem be canalized into
Mouth road, the as unbalance crossing inlet road of differentiation lane share rate.
In specified time interval ti, the unbalance foundation of lane share rate occur is formula (3):
Wherein,Represent i-th of lane unbalance index, calculation formula (4) are as follows:
Lane unbalance index is 0, represents this lane pressure share rate and meets normal level, and lane unbalance index is 1, is represented
This lane pressure share rate is too small or excessive.Wherein, σ is the standard deviation of whole lane share rates in this time interval, is calculated public
Formula (5) is as follows:
Lane share rate is of short duration unbalance in ti time interval, is unable to characterize the long-standing problem of entrance driveway canalization, therefore wants
Identify that the long-term unbalance ability of lane pressure share rate is significant.For this purpose, carrying out the unbalance judgement in a variety of different time periods:
In 24 hours one day, the time interval number of the unbalance generation of lane pressure share rate is(value be [0,
288]).WhenIt is unbalance to indicate that pressure share rate in lane occurs for the same day.Wherein, δD(value is [1,288]) is
Day unbalance judgment threshold of share rate.
In one month, the number of days of the unbalance generation of lane pressure share rate is(value is [0,30], it is assumed that one
A month based on 30 days).WhenIndicate that of that month generation lane pressure share rate is unbalance.Wherein, δM(value be [1,
It 30]) is the unbalance judgment threshold of moon share rate.
Within a season, the number of days of the unbalance generation of lane pressure share rate is(value is [0,90], it is assumed that
One season is based on 90 days).WhenIndicate that of that month generation lane pressure share rate is unbalance.Wherein, δS(value
For [1,90]) it is the season unbalance judgment threshold of share rate.
During the entrance driveway that above-mentioned identification is canalized there are problem, it is related to 3 judgment threshold parameters, respectively δt_D、δD_M
And δD_S, the value range difference of these three threshold parameters.And the setting value of threshold parameter is smaller, that is, represents this recognition methods
Sensitivity is higher, this crossing inlet road is more easily recognizable as that entrance driveway of problems is canalized.For this purpose, giving different spirits
The threshold parameter of sensitivity, to be applicable in the scene of different demands, as shown in table 1.
The threshold parameter of 1 different sensitivity of table
Step 204, according to the pressure share rate in each lane in first crossing inlet road, determine that described first intersects
The pressure share rate of mouth each direction of traffic of entrance driveway.
After identifying and there are problems that the first crossing inlet road of canalization, it is necessary to further be arranged according to each lane
Team's pressure share rate, calculates pressure share rate mean value of all directions under different time scales, so as to the canalization to entrance driveway into
Row optimization amendment.
Within the specific period, the queue pressure share rate of crossing inlet road all directions is respectively (m direction of traffic is shared, direction lane counting number is o1,o2,...,om), calculate pseudo-code such as
Shown in table 2.
The queue pressure share rate of 2 all directions of table calculates pseudo-code
It can be obtained by the pressure share rate of each direction of traffic of entrance driveway through the above way.
Step 205, according to the pressure share rate in each lane in first crossing inlet road and each driving side
To pressure share rate canalization amendment is carried out to first crossing inlet road.
After obtaining the pressure share rate that each driving is worried, so that it may the first crossing inlet road is modified,
It mainly can be with are as follows: first according to the pressure share rate in each lane in the first crossing inlet road, determine the first crossing inlet road
Pressure share rate target value.Then according to the pressure share rate of each direction of traffic and the pressure in the first crossing inlet road point
The target value of load rate determines the number of track-lines that each direction of traffic should distribute.Finally according to the vehicle that should be distributed of each direction of traffic
The actual number of track-lines of road number and each direction of traffic redistributes fleet for the first each direction of traffic in crossing inlet road.
Under the queue pressure share rate known conditions of entrance driveway all directions, to balance all directions pressure share rate as mesh
Mark, the i.e. equal progress entrance driveway canalization amendment of each lane pressure share rate of all directions.Accordingly, all lane pressure of entrance driveway
The target value of share rate is formula (6):
The logic for then distributing lane for each direction is: the pressure share rate in each direction is divided to each lane
Afterwards, the pressure share rate in each lane reaches unanimity.The number of track-lines that each direction should be distributed can then be calculatedCalculation formula (7) is as follows:
…
In the ideal case, the sum of all directions number of track-lines known is calculatedWith existing canal
The sum of all directions number of track-lines o in change1+o2+...+omIt is equal.
Canalization Optimal improvements are carried out to crossing inlet road, as under existing lane quantity permanence condition, for each into
Mouth road driving direction redistributes the process in lane.Default each lane and at most distribute 3 driving directions, is crossing inlet road
Middle turniLane is distributed in direction, and the process that Optimal improvements are canalized in crossing inlet road is as shown in Figure 4.Steps are as follows:
(1) leftmost side is judged with the presence or absence of unallocated complete shared lane, if it does, going to (2) step；If do not deposited
Going to (3) step.
(2) all shared lanes are occupied, and are updatedGo to (3) step.
(3) after judgement updatesWhether integer part is greater than 0, if so, going to (4) step；If it is not, going to
(5) step.
(4) respective integer lane is distributed, (5) step is gone to；
(5) after judgement updatesFractional part value, if value be [0.5,1), go to (6) step；If value
For [0.3,0.5), go to (7) step；If value is (0,0.3), lane is not distributed, (8) step is gone to.
(6) judgeIt whether there is, if it does not, not distributing lane, go to (8) step；If it does, distributionLane, goes to (8) step.
(7) judgeIt whether there is, if it does not, not distributing lane, go to (8) step；If it does, distributionLane, goes to (8) step.
(8) distribution terminates.
