Section1 vehicle flowrate and occupy situation, the 3rd video detector 213 is arranged on buffering area Section2, carrys out car for detecting
Region Section3's comes car queue length and each track traffic statistics etc..
In the present embodiment, each signal lamp subelement 41 includes multiple section control signal lamps 411 and multiple crossings are believed
Signal lamp 412, above-mentioned multiple section control signal lamps 41 are arranged on buffering area Section2, are mainly used in carrying out car region Section3
Variable-structure control, and inform the crossing direction for let pass required for the Section3 of car region, above-mentioned multiple belisha beacons 412
It is arranged on crossing position, indicated for crossing traffic information, the corresponding signal lamp in each crossing direction represents it to strain structure
Direction and state that each track is let pass.
The major control thinking of the structure changes traffic signal control system be exactly using in Fig. 2 come car region Section3
Track clearance direction is controlled, for example, being significantly more than straight trip when video detector detects south toward north vehicle of turning left
During vehicle, the structure changes traffic signal control system can just control signal lamp car in the future region Section3 of Nan Wang North Roads section
The left turning vehicle of first track 1. respectively enter structure changes region Section1 1., 2. track, or even 3. track, further according to
The structure changes track situation being actually discharged into, takes turns to when front direction left turn phase is let pass, control belisha beacon let pass 1., 2. car
Road, or even 3. the left-hand rotation in track is let pass.It similarly can also so control straight trip and right-turning vehicles to let pass to control, the structure changes traffic
The purpose of whistle control system is exactly that control each track of crossing is let pass, so as to be passed through come car situation according to actual vehicle
The optimization of maximal efficiency.
In addition, equally also there is vehicle detection unit 21 in structure changes region Section1, it is ensured that each each phase
Clearance can be complete, car is not had under its current phase, it is impossible to crossing is impacted to the clearance of subsequent vehicle, and
When detecting all clearance completions of current clearance direction, then it can terminate current phase in advance, not influence other to assist
Adjust and let pass in the case of passing through into next phase.Meanwhile, vehicle detection unit 21 equally is had been provided with crossing,
The jam situation at crossing is detected, when crossing is smooth, according to the normal clearance all directions vehicle of Signalized control scheme；Work as detection
During to crossing congestion, the clearance of the belisha beacon 412 and section signal lamp 411 of congestion directional correlation connection can be controlled, so that
Bigger congestion will not be caused because of there is car to drive into crossing under crossing congestion, can then be reverted to after crossing is smooth normal
Control program.
A section nearest apart from crossing is designed as road direction by the present invention by the way that road is carried out into Discrete control
Variable structure, signal lamp unit 4 is rationally utilized by obtaining the information of vehicles that corresponding vehicle detection unit 21 is arrived on road
The space in structure changes section, binding signal lamp indicates that vehicle is passed through according to signal lamp arrow, so as to realize the maximum effect of progress
The access control of rate crossing.
It is noted that under the certain situation of the present embodiment, vehicle detection unit 21 can also use other types
Wagon detector.For example：Each vehicle detection unit 21 include at least one first coil detector, at least one second
Coil checker and at least one tertiary coil detector (not shown), first coil detector are embedded in structure changes region
Section1, for detecting crossing congestion situation, the second coil checker is embedded in buffering area Section2, becomes knot for detecting
The vehicle flowrate in structure region and occupy situation, tertiary coil detector, which is embedded in, carrys out car region Section3, for detecting Lai Che areas
Car queue length and each track traffic statistics are come in domain.Certainly, each vehicle detection unit 21 can also use other kinds of
Wagon detector, for example：Each vehicle detection unit 21 includes multiple supersonic detectors, infrared detector or detections of radar
Device etc..
The present invention by road by carrying out Discrete control, and there is each section corresponding wagon detector to be detected,
The information of vehicle flowrate in each track in each region can be detected in real time with reference to video detector, coil checker etc., carry out car row
Team's length information, road occupy information, event detection information and crossing congestion information etc., effective by the way that data above is carried out
Integrate and handle, it is final to determine which section of crossing needs situation about letting pass, then carry out belisha beacon 412 and control so that
Each track clearance direction at crossing can control and change, so that the traffic capacity and traffic efficiency of road are greatly improved,
It can also improve the intelligent level of traffic signal control system simultaneously.
In a word, the structure changes traffic signal control system is controlled to belisha beacon 412 and section signal lamp 411,
It is standby with reference to crossing, a variety of wagon detectors in section, enable to the structure changes traffic signal control system to detect road surface in real time
The passage situation of each track vehicle, further according to the passage situation of vehicle, control vehicle enters crossing structure changes region
Section1 is passed through, and can more optimize road, improves the traffic efficiency and crossing clearance efficiency of vehicle, while by
In by the way of variable-structure control, it can be detected for various congestions and anomalous event, so as to control vehicle to drive into, really
Guarantor does not result in further congestion, and can also be under control signal lamp prior-release abnormal conditions vehicle, reduce crossing accident
The probability of generation.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
