It referring to fig. 2, is structural representation of the server under a kind of embodiment in a kind of traffic signals conditioning unit of the application
Figure；
As shown in Figure 2, in a kind of possible embodiments, data receipt unit 11, network transmission are configured in the server 1
Unit 12 and data processing unit 13；
Wherein, the data receipt unit 11, for receiving the traffic flow data that signal controlling machine acquires in region, and root

The data processing unit 13, the traffic flow data for being received according to data receipt unit are assisted by dynamic
The flow saturation factor and dissipation rate at crossing where adjusting algorithm to calculate separately out, dynamic configuration traffic are let pass tactful.In the present embodiment
In saturation factor refer to that in continuous green time, certain entrance driveway can be by the maximum stable flow rate of vehicle；Dissipation rate refers to
In continuous green time, certain exit ramp can pass through the maximum stable flow rate of vehicle；According to transport need and the traffic capacity
Size relation, intersection traffic state can be divided into undersaturated condition, saturation state and hypersaturated state；According to the logical of queuing vehicle
Row delay situation analysis, undersaturated condition crossing are let pass in the time in green light, and queuing vehicle can pass through crossing completely.It calculates full
Can be by magnitude of traffic flow acquisition software with rate, the vehicle for acquiring specified crossing of multiple periods enters quantity, then averages,
As saturation factor；Calculating dissipation rate is then the vehicle outflow number that specified crossing of multiple periods is acquired by magnitude of traffic flow acquisition software
Amount, then averages, as dissipation rate.If it is excessive that the flow saturation factor acquired is greater than dissipation rate, need to consider to increase green
Lamp time, adjustment are let pass tactful.
As the core component of server 1, data processing unit substantially uses ARM Cortex family chip, and
It is integrated with the dynamic coordinate algorithm of special disposal regional traffic coordinated control in the chip；It is handed over when obtaining each crossing in all subregion
When logical data, flow saturation factor and dissipation rate that dynamic coordinate algorithm calculates each crossing is respectively adopted, implements to grasp congestion feelings
Condition, further according to the practical congestion level in each crossing, according to corresponding weight coefficient, dynamic configuration traffic is let pass tactful.
Weight coefficient in the present embodiment, which uses, to be thought to set, such as there are four direction lanes at some crossing, wherein being divided into
Major trunk roads and subsidiary road, then the weight coefficient of major trunk roads setting should be higher, such as setting 1.1；The weight coefficient of subsidiary road should be compared with
It is low, such as setting 0.9；When actually entering measurement period, calculates practical transit time and need to refer to weight coefficient, it is assumed that actual measurement
Major trunk roads transit time afterwards is 30, then the time after calculating should be 30*1.1=33；Subsidiary road transit time is 20, then calculates
Time afterwards should be 20*0.9=18.
Referring to Fig. 3, for the flow chart of dynamic coordinate algorithm used in the examples described in Fig. 2；
From the figure 3, it may be seen that data processing unit 13, when executing data processing, used dynamic coordinate algorithm includes:
S10: according to traffic flow data, period library is generated；Firstly, comprehensive descision analysis is carried out, according to locating region or sub-district
The historical traffic information of each each phase in crossing in domain generates the corresponding relationship in period and flow in conjunction with saturation volume rate；Specifically
, it is the decomposition step figure of step S10 in Fig. 3 referring to fig. 4；
The step is also specifically decomposed into the following steps:
S11: the oral sex through-current capacity that satisfies the need is segmented；For example, can be segmented according to the different sampling intervals, the sampling interval can be with
For the segmentation of daily morning and evening time slice, working day and nonworkdays, working day and festivals or holidays segmentation etc., by piecewise acquisition,
Understand the trip rule of current region；
S12: each flow rate zone right endpoint optimal period is calculated；Optimal period can be crossing working day optimal period, non-
Working day optimal period, early evening peak optimal period, flat peak optimal period etc.；Right endpoint is commonly referred to as period end, right end
Point optimal period indicates that this period all uses optimal period.
S13: flow rate zone and corresponding period are stored；In order to execute control process in, can be according to different grain size pair
The calculated result obtained after traffic parameter is for statistical analysis exports the report of various needs；Granularity indicates granular size, specifically
Parameter area is referred to, such as is accurate to hour, minute, day, or by lane, direction, crossing etc..
When step S10 process is finished, can start in real time to each crossing real-time monitoring；
S20: transport need situation of change is obtained, is judged whether to take transport need amendment according to transport need situation of change；
When for judging whether to take amendment to transport need, it usually needs a parameter threshold value is previously set, such as allow to reach
Maximum queue length, highest waiting time or unidirectional maximum vehicle flowrate etc., set parameter threshold value may be one, it is also possible to
To be multiple, when Current traffic changes in demand, the actual measurement parameter value that will lead to current crossing is more than one or more parameter threshold values, because
This judgement needs to take correction measure to transport need；
S30: if desired taking amendment to transport need, then corrects transport need according to weight coefficient；According to above-mentioned technology contents,
Weight coefficient can be done to amendment appropriate, such as the weight coefficient of the weight coefficient of major trunk roads and subsidiary road is become remote or is approached,
Or individually increase or decrease the weight coefficient in a certain lane.
S40: transport need is compared with the parameter in period library, selects corresponding cycle length；The corresponding period is long
Spend the control for executing corresponding traffic signal controlling machine；
Referring to Fig. 5, for another flow chart of dynamic coordinate algorithm used in the examples described in Fig. 2；
Further, it after executing step S40, in order to improve coordinating control of traffic signals efficiency, needs to generate at the first time and control
Scheme processed, and it is sent to corresponding traffic signal controlling machine:
S41: according to the corresponding period, transport need and phase weights coefficient in conjunction with each phase generate the signal control at each crossing
Scheme processed；
S42: the signal timing plan at each crossing is sent to corresponding traffic signal controlling machine.
Finally, needing to evaluate control effect, S50: evaluating current correction effect, according to evaluation result tune
Whole weight coefficient；Specifically, first calculating in conjunction with the green light utilization power of each phase in each signal period and there emerged a the utilization of phase green light
Rate is compared with the utilization rate before amendment according to counted utilization rate, determines crossing control effect；Control effect is according to degree
Size can be divided into: poor, poor, common, preferable, good；While evaluation, nearest several signal period each phase green lights are utilized
Utilization rate suitably adjusts phase weights coefficient, guarantees the accuracy of phase weights coefficient.
As shown from the above technical solution, the dynamic coordinate algorithm used in the application is enriching accurate traffic data support
Under, the intelligent decision optimization that road traffic control is changed into data-driven from traditional model cootrol is realized, data point are passed through
Dynamic auto control is realized in the optimal estimation for analysing required parameter and scheme in carry out system control, mitigates road traffic signal control
The workload of system putting maintenance into practice processed can better adapt to the variation characteristic of road traffic flow, realize more accurate more initiative road
Road traffic control.
