Description
Technical field
The invention belongs to traffic signalization field, believes more particularly, to the traffic under a kind of crossing flow asymmetric case
Number control method.
Background technology
With being continuously increased for vehicle, the magnitude of traffic flow on road also increases constantly, traffic congestion, resistance on road
Plug and traffic accident are consequently increased, and " urban transportation disease " turns into the most thorny issue in Modern Urban Living.
In the prior art, intersection release manner is fixed a set of or had according to different periods different using whole day mostly
Phase sequence sequence scheme, at the relatively large crossing of flowed fluctuation, the fixed period is not with a set of phase sequence control, corresponding effect
It is highly desirable, and for the larger crossing control program of flowed fluctuation largely using multi-period scheme policies, inductive scheme and from
Suitable solution etc..Wherein, multi-period scheme needs the tracking crossing situation of traffic professional month after month throughout the year, once there is wagon flow to become
The variation of gesture needs scheme corresponding to time update, but requirement of such a scheme for designer is of a relatively high, secondly consumes
It is relatively more to take energy；In addition, sensing control be adjusted in real time according to wagon flow let pass the time scheme, and sense control have to according to
Rely with current phase sequence scheme, and current phase sequence scheme can not be changed, therefore during for north-south, East and West direction vehicle flowrate asymmetry
Treatment effect unobvious, or even can also cause waste of time.

Relative to prior art, the traffic signal control method under a kind of crossing flow asymmetric case of the present invention
Have the advantage that：
(1) the traffic conditions independent operating of the traffic control signal only according to the crossing at each crossing, existing skill are avoided
The crossing adjacent thereto when congestion occurs in a crossing easily duplicates congestion in art and vehicle drives in the wrong direction and causes anti-excessive congestion；
The crossing that congestion can not only occur to this in the present invention carries out traffic signalization, while can also perform the 4th phase by order
Position, the 5th phase, extend adjacent intersection straight trip green light lighting time control adjacent intersection, performed so as to realize that adjacent intersection coordinates
Traffic dispersion, adjacent intersection is avoided to repeat congestion and anti-excessive congestion；
(2) in addition, when the switching under the flow asymmetric case of crossing by first phase and second phase, third phase,
The larger vehicle flow direction of straight trip, left turn traffic amount is dredged, reduces the waiting time of the larger section vehicle of flow；
(3) in peak period, because of the traffic congestion that flow increases sharply or traffic accident triggers, can be led to by site traffic management and control personnel
The method for crossing the present invention, while management and control adjacent intersection, can either so solve the vehicle congestion of adjacent intersection, can reduce again existing
The traffic control personnel of field.
