Description
Technical field
The invention belongs to urban road transportation control fields, and in particular to a kind of controlling of bus priority based on the green wave of main line
Method.
Background technique
" intelligent transportation " is that a novel intelligent traffic system based on complete perception is built using technology of Internet of things,
The important means for having become and solving the problems, such as urban traffic control, alleviate vehicle congestion situation.Controlling of bus priority mainly uses nothing
The technologies such as line radio frequency (RFID), high-speed image identifying processing, satellite positioning, enable the vehicle of high-speed cruising by " perception ", phase
Closing data can acquire in real time, arranges and analyze, effectively the problems such as solution automatic vehicle identification, dynamic monitoring；On this basis,
By traffic signalization, traffic flow reasonable layout is guided, dynamic organization's management of urban transportation is realized, improves traffic circulation effect
Rate ensures that city is unimpeded orderly.
Existing major part priority system, Controlling model is simple, algorithm is single, and excessively focuses on the preferential of public transport
Traveling, to affect the normally travel of public vehicles.When vehicle flowrate is larger, public vehicles overstocked and influence in turn public
The passage of friendship.
Therefore, it is necessary to a kind of new technical solutions to solve the above technical problems.
Summary of the invention
To solve the deficiencies in the prior art, it is an object of the invention to propose a kind of public traffic in priority control based on the green wave of main line
Method processed can improve the traffic efficiency of public transit vehicle and public vehicles simultaneously.
In order to achieve the above objectives, the present invention adopts the following technical scheme that: a kind of public traffic in priority based on the green wave of main line
Control method, the control method combine crossing controlling of bus priority and the green wave of main line, comprising:
(1) when receiving the instruction of crossing controlling of bus priority, first judge whether current crossing reaches green wave and synchronize, that is, sentence
Deviation oscillation between disconnected current phase difference and the phase difference standard value of setting whether in error range, if in error range
It is interior, then execute the instruction of crossing controlling of bus priority；If in error range, not executing the instruction of crossing controlling of bus priority,
Carry out the synchronous setting of green wave；
(2) the synchronous setting of green wave is carried out, that is, adjusts the length of each phase, reduces the phase difference mark of current phase difference and setting
Deviation oscillation between quasi- value, makes deviation oscillation in error range, then executes the instruction of crossing controlling of bus priority；
(3) after having executed the instruction of crossing controlling of bus priority every time, the phase difference standard value of current phase difference and setting it
Between deviation oscillation will increase, broken original green wave synchronous regime, needed to carry out the adjusting offset of a new round.
Preferably, the setting of the crossing controlling of bus priority is arranged, knot using high accuracy positioning on bus is installed on
It closes urban road network Vector Data Model and positions public transport real time position in real time, trigger public transport when vehicle enters crossing trigger region
Red time is shortened in priority acccess control operation, i.e. extension green time.
Preferably, when multi-direction while when thering is bus to pass through crossing, according to the priority level of route, ensure that all directions are public
Hand over vehicle sequence prior-release.
Preferably, the setting of the green wave of the main line, by adjusting the phase difference of intersection signal control machine, it is ensured that main line is formed
Green wave band improves the travel speed of arterial road vehicle, improves the whole traffic condition in control area.
Preferably, when the setting green wave of main line, whether there is public transportation lane according on road, pass through bus parking time, public affairs
It hands over queue length, green wave band width to optimize, forms final allocation plan.
The invention has the beneficial effects that: crossing controlling of bus priority and the green wave method of main line are used in combination, form one
Combined signal control strategy is covered, the traffic efficiency of public transit vehicle and public vehicles can be improved simultaneously, reaches the passage of the two
A kind of balance；When realizing the green wave of main line, in conjunction with the shadows such as public transportation lane, bus parking time, public transport queue length, green wave band be wide
The factor of sound optimizes.
Specific embodiment
Below in conjunction with detailed description of the invention by specific embodiments.
A kind of method for controlling bus priority based on the green wave of main line, the control method is by crossing controlling of bus priority and main line
Green wave combines, and includes the following steps:
(1) when receiving the instruction of crossing controlling of bus priority, first judge whether current crossing reaches green wave and synchronize, that is, sentence
Deviation oscillation between disconnected current phase difference and the phase difference standard value of setting whether in error range, if in error range
It is interior, then execute the instruction of crossing controlling of bus priority；If in error range, not executing the instruction of crossing controlling of bus priority,
Carry out the synchronous setting of green wave；
(2) the synchronous setting of green wave is carried out, that is, adjusts the length of each phase, reduces the phase difference mark of current phase difference and setting
Deviation oscillation between quasi- value, makes deviation oscillation in error range, then executes the instruction of crossing controlling of bus priority；
(3) after having executed the instruction of crossing controlling of bus priority every time, the phase difference standard value of current phase difference and setting it
Between deviation oscillation will increase, broken original green wave synchronous regime, needed to carry out the adjusting offset of a new round.
Wherein, the setting of crossing controlling of bus priority: it is arranged using high accuracy positioning on bus is installed on, in conjunction with city
Road network Vector Data Model positions public transport real time position in real time, and public traffic in priority control is triggered when vehicle enters crossing trigger region
Red time is shortened in system operation, i.e. extension green time.Meanwhile when multi-direction while when thering is bus to pass through crossing, according to line
The priority level on road ensures all directions bus sequence prior-release.
The setting of the green wave of main line (the green wave of public transport): by adjusting the phase difference of intersection signal control machine, it is ensured that main line is formed
Green wave band improves the travel speed of arterial road vehicle, improves the whole traffic condition in control area.It is green that main line is set simultaneously
When wave, whether there is public transportation lane according on road, it is excellent by bus parking time, public transport queue length, the wide progress of green wave band
Change, forms final allocation plan.
