Signal lamp becomes blue or purple, and when traffic light system is the 4th kind of state, the vehicle on Through Lane can be with public transit vehicle
Bus zone is shared, signal lamp can be adjusted separately according to the vehicle accounting of straight way and left changing lane, and simultaneously can basis
Road conditions carry out sharing for dedicated bus lanes, improve the utilization rate of resource, the traffic evacuation time is shorter.
Monitoring part monitors left changing lane vehicle specific gravity on the first major trunk roads and is denoted as third specific gravity；It monitors part and monitors the second major trunk roads
Upper left changing lane vehicle specific gravity is denoted as the 4th specific gravity；When third specific gravity is greater than four specific gravity, real-time extension the first major trunk roads signal
The left-hand rotation duration of lamp, specific gravity are the ratio between the vehicle weight on each lane and all vehicle weights on all lanes in crossing.
Image acquisition device and main control unit are electrically connected, when image acquisition device monitors ambulance or fire fighting truck by crossing
When, it is current to make ambulance or fire fighting truck, while suspending other lane vehicle pass-throughs for adjustment signal lamp state, until ambulance or
Fire fighting truck is driven out to crossing；
When having ambulance or fire fighting truck by crossing, adjustment signal lamp state makes ambulance or fire fighting truck place
The evergreen passage of signal lamp on lane, while suspending the traveling of vehicle on remaining lane, it gives way compared to present hiding, safety
It is higher.
It is such as boundary with crossroad signal lamp as shown in Fig. 2, can also realize finer monitoring in the present invention,
One crossing is divided into four roads, the road that the first major trunk roads are located at signal lamp two sides is denoted as X1 road and X2 road respectively,
Signal lamp on X1 road is denoted as H1 signal lamp, and the signal lamp at X2 road cross is denoted as H2 signal lamp, X1 road
Vehicle specific gravity on upper Through Lane is denoted as X11, and the vehicle specific gravity on X1 road on left turn lane is denoted as X12, and X1 road is upper right
Vehicle specific gravity on changing trains or buses is denoted as X13, and the vehicle specific gravity on X1 road on public transportation lane is denoted as X14, and so on, it is unlimited
In four runways.
Vehicle specific gravity on X2 road on Through Lane is denoted as X21, and the vehicle specific gravity on X2 road on left turn lane is denoted as
Vehicle specific gravity on X22, X2 road on right-turn lane is denoted as X23, and the vehicle specific gravity on X2 road on public transportation lane is denoted as
X24, and so on, it is not limited to four runways.
The road that second major trunk roads are located at signal lamp two sides is denoted as Y1 road and Y2 road respectively, the letter on Y1 road
Signal lamp is denoted as H3 signal lamp, is located at, and the signal lamp at Y2 road cross is denoted as H4 signal lamp, the vehicle on Y1 road on Through Lane
Specific gravity is denoted as Y11, and the vehicle specific gravity on Y1 road on left turn lane is denoted as Y12, the vehicle ratio on Y1 road on right-turn lane
It is denoted as Y13 again, the vehicle specific gravity on Y1 road on public transportation lane is denoted as Y14, and so on, it is not limited to four runways.
Vehicle specific gravity on Y2 road on Through Lane is denoted as Y21, and the vehicle specific gravity on Y2 road on left turn lane is denoted as
Vehicle specific gravity on Y22, Y2 road on right-turn lane is denoted as Y23, and the vehicle specific gravity on Y2 road on public transportation lane is denoted as
Y24, and so on, it is not limited to four runways.
When X11 be greater than X21, while X11 be greater than X22, X12 be greater than X22 when, extend H1 signal lamp straight trip duration and turn left
Duration, and keep straight on duration with turn left can synchronize be open to traffic, at this point, because X2 road left turn lane vehicle specific gravity is smaller, pause H2 believes
The left rotaring signal of signal lamp is changed to left-hand rotation red light, when X14 is less than X11, and X14 is less than X24, public transportation lane X14 and Through Lane
X11 is shared, and signal lamp H1, H2 becomes the 4th kind of state at this time, for distinguishing normally travel signal lamp, can be color it is different or
Instruction changes.
And so on, when Y11 be greater than Y21, while Y11 be greater than Y22, Y12 be greater than Y22 when, extend H3 signal lamp straight trip
Duration and left-hand rotation duration, and keep straight on duration and left-hand rotation can synchronize be open to traffic, at this point, because Y2 road left turn lane vehicle specific gravity compared with
It is small, suspend the left rotaring signal of H4 signal lamp, is changed to left-hand rotation red light, when Y14 is less than Y11, and Y14 is less than Y24, public transportation lane
Y14 and Through Lane Y11 are shared, at this time signal lamp H3, H4 become the 4th kind of state can for distinguishing normally travel signal lamp
To be that color is different or instruction changes.
By monitoring part real-time monitoring crossing road conditions, real-time adjustment signal lamp is carried out according to the vehicle specific gravity of each runway
State for time, accurate intelligent, in real time adjustment, traffic congestion can be carried out for the driving road-condition at specific road section and specific crossing
It is higher to solve efficiency, to realize intelligent evacuation traffic congestion, reduces the congestion time, avoids traffic paralysis.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
