Description
Technical field
A kind of method that vehicle passes through crossing by the method at crossing, especially left turning vehicle.
Background technique
Present city hands over energy problem very serious, and in morning peak, not far distance stifled one or two hour is also very often
See, what is be blocked is all motor vehicle, pedestrian and non motorized vehicle get lodged in crossing cannot get through it is actually rare；Be blocked is on the way to life
With the unnecessary consumption of the energy；Motor vehicle is not in congestion in the middle section of road, the generation of congestion be all since crossing, then to
The middle section of road is spread, so that spreading to junction perimeter, eventually causes comprehensive congestion；The road surface at crossing is very golden expensive, and existing
The synthesis utilization rate on the road surface that traffic method crossing motor vehicle passes through is 50%, this is a kind of serious waste；In existing patent
There are several improved methods, application can be can't see in reality, first is that the influence of the force of habit, the other is effect is not obvious enough.
With 3 lane of straight trip more in existing city, for 1 lane of turning left, when straight trip non-motor vehicle passes through crossing, crossing
The vacancy rate on road surface is 25%, and when left-hand rotation motor vehicle passes through crossing, the vacancy rate on crossing road surface is 75%, mainly left-hand rotation motor vehicle
Affect the utilization rate on whole crossing road surface.
In grant number CN106023606B, although left turning vehicle is allowed to be moved to the left side of road in advance, but to widen road
Face, and behave also more complicated.
In grant number CN102051846B, left turning vehicle apart from the one of crossing a distance by turning around U-shaped road, left-hand rotation vehicle
It first to turn right and to turn around to realize again, a biggish turning radius, especially bus be needed when turning around, in city
Widening road is a difficult thing；Left turning vehicle needs to repeat to occupy lane.
In present traffic method, the road surface vacancy rate average out to 50% at center crossing, the vehicle institute road occupying being driven out to from crossing
The time on road 50% is idle, is 50% in the 50% synthesis vacancy rate using road surface in the time.
Summary of the invention
To solve the above-mentioned problems, method of the invention is: crossroad originally is center crossing, at center crossing
A small crossing is respectively provided on the road in each direction, which enters and exits；Small crossing distance
The length at center crossing is at least a length when green light period straight trip motor vehicles wait.
There is 50% time there is no motor vehicles on the road surface that motor vehicles sail out of center crossing, utilizes the control of traffic lights
A period passed through without motor vehicles is formed, becomes small crossing, the left-hand rotation motor vehicles for driving towards center crossing can use
This period translates from small crossing to the direction to be turned left, and left-hand rotation motor vehicles are moved to the outside of pedestrian and non motorized vehicle, then
Turn left to the direction to be travelled；Institute's having time is not required on the lane shared by the motor vehicles for driving towards center crossing vehicle
Pass through, using the time of the control available 50% of traffic lights, forms a small crossing, left-hand rotation motor vehicles on the lane
It is reached and is sailed out of on the road junction roadway of center by the small crossing.
Right turning vehicle is current in the outside of left turning vehicle, can receive the control of traffic lights together with left-hand rotation motor vehicles
System, can also not have to traffic lights and control, and pass through small crossing in the gap that pedestrian passes through.
Using motor vehicle being made to rise to original twice, vehicle and pedestrian by the ability at crossing after such method
The time of red light is waited to be reduced to original 1/3.
Further, on " fourth " word crossing in use, the road of through vehicles is not no straight way road, intersect with it
To there is straight way road；Small crossing is not set on having straight way road, crossing a distance is equipped with small crossing at the center no straight way Lu Shangyu；It sails
The other side for moving to road by small crossing to the vehicle at center crossing and pedestrian, when the through vehicles and pedestrian that have straight way road are logical
After row, there are the left-hand rotation motor vehicles of straight way road and the left-hand rotation motor vehicles of no straight way road to pass through center crossing simultaneously,
Two lanes do not intersect, and are non-motorized lane and pavement, all left-hand rotation motor vehicles, non-motor vehicle, row between two lane
People passes through center crossing simultaneously；There are the left turning vehicle of straight way road and pedestrian that can continue to drive through small crossing to be arrived
The road side reached；After the left turning vehicle for having straight way road to sail passes through small crossing completely, the left turning vehicle and row of no straight way road
People is reached the other side without straight way road and waited by small crossing passes through center crossing.
Being divided on having straight way road has left-hand rotation side and without left-hand rotation side, has the pedestrian of left-hand rotation side and non-motor vehicle first left when turning around
Go to Accreditation Waiting Area waiting, through vehicles by when complete turn around；When the pedestrian of no left-hand rotation side and non-motor vehicle turn around, first keeping straight on
It waits when vehicle passes through in Accreditation Waiting Area, when left turning vehicle and pedestrian pass through center crossing, passes through together with other vehicles, pedestrian
Center crossing completes to turn around.

Simultaneously switch to red light or switch to green light simultaneously.
If long green light time is T, through vehicles let pass by green light after from the time that Center Road mouthful reaches small crossing be T1 ,
The time that one current period is is 2T；One cycle of operation at center crossing is divided into two periods, and the first period the 9th is red green
Lamp 1 is green light, and the tenth traffic lights 5 are red light, and the tenth traffic lights 5 of the second period are green light, and the 9th traffic lights 1 are red light.
One cycle of operation at small crossing was also classified into for two periods: the first first group of period traffic lights are green light, and second group red
Green light is red light, the time of backward delay T1 when than the 9th 1 green light of traffic lights；Second second group of period traffic lights are green light, the
One group of traffic lights is red light, than the time of the green time backward delay T1 of the tenth traffic lights 5.
When the 9th traffic lights 1 are green light, when this time is 0, the vehicle on the 9th lane 01 is arrived by center crossing
Up on the lane where the 9th traffic lights 1, second group of traffic lights is still green light at this time, and the vehicle that second group of traffic lights is commanded is logical
Too small crossing；The pedestrian of North and South direction and non power driven vehicle pass through center crossing.
By time T1Afterwards, the through vehicles of North and South direction reach the small crossing of North and South direction, and second group of traffic lights switchs to
Red light, the vehicle that second group of traffic lights is commanded stop passing through small crossing；First group of traffic lights switchs to green light, first group of traffic lights
The vehicle commanded is by small crossing, the small crossing including North and South direction and east-west direction.
After time T, the 9th traffic lights 1 switch to red light, and the vehicle on the 9th lane 01 stops passing through center crossing；The
Ten traffic lights 5 switch to green light, and the vehicle on the tenth lane 05 is entered by center crossing on the lane at 5 place of the tenth traffic lights；
The pedestrian of east-west direction and non power driven vehicle pass through center crossing；First group of traffic lights is still green light at this time.
The red T that crosses adds T1After time, the through vehicles of east-west direction reach small crossing, first group of traffic lights by center crossing
Switch to red light, the vehicle that first group of traffic lights is commanded stops passing through small crossing；Second group of traffic lights switchs to green light, and second group red
The vehicle that green light is commanded passes through small crossing；Small crossing including North and South direction and east-west direction.
After red mistake T adds T time, the tenth traffic lights 5 switch to red light, and the through vehicles stopping of east-west direction passes through Center Road
Mouthful；9th traffic lights 1 switch to green light, and the true driving of North and South direction begins through center crossing；It is identical when with time 0, it constitutes
One circulation.
Fig. 1 is 0 up to T1When among state, Fig. 2 is T1The state at moment, Fig. 3 are the states at T moment, Fig. 4 be T up to
T adds T1When among state, Fig. 5 is T+T1The state at moment, Fig. 6 be T add the T moment state and next current period 0
When state.
The through vehicles time of east-west direction is T1When center crossing, time 2T driven towards by small crossing1When reach center
Crossing, when the time is T, the tenth traffic lights 5 switch to green light, and it is T that the through vehicles of east-west direction, which want the waiting time at center crossing,
Subtract 2T1, the true driving of North and South direction is similar with the through vehicles of east-west direction；When T is equal to 2T1When, through vehicles are from path
Just green light when mouthful reaching center crossing, withouts waiting for directly passing through center crossing and next small crossing.
The spacing at small crossing Yu center crossing, small crossing and center crossing are set according to the spacing at the city crossing Zhong Liangge
Spacing is preferably the 1/3 of two centers crossing spacing；The minimum spacing at small crossing and center crossing is through vehicles in Center Road
Length when being waited at mouthful；When small crossing distance center crossing is longer, the traffic lights period is adjusted, through vehicles pass through Center Road
Without waiting for through vehicles will wait for a period of time at center crossing when since two centers crossing distance is shorter when mouth.
Most of non-motor vehicle in present city is electric vehicle, and speed per hour is generally at 20 kilometers or so, the speed change of higher gears
Bicycle can also reach this speed, in T plus 2T1Time in can pass through two small crossings, will not two small crossings it
Between wait.
T when one green light of red times such as non-motor vehicle, the time of the red lights such as traditional mode are three green time 3T, this
Sample one reduces non-motor vehicle Law-abiding cost, can also reduce the behavior of non-motor vehicle made a dash across the red light, can also make motor vehicle
It increased by the ability at crossing；Pedestrian generally less worries, and may will wait at center crossing and small crossing, but all can
Less than one green time T.
When the speed per hour of motor vehicle is 30 kilometers, the speed per hour of non-motor vehicle is 20 kilometers, and T is equal to 2T1When, non-motor vehicle is also
T1Time pass through next small crossing.
Embodiment 2: as shown in figure 9, this crossing is " fourth " crossing, the north at crossing does not have road, on road in the south
A small crossing is set away from a distance with center crossing, Accreditation Waiting Area 2 is non-motor vehicle and the waiting area that pedestrian turns around, and left-hand rotation line 3 is
The left-hand rotation line of non-motor vehicle and pedestrian；After the through vehicles of east-west direction stop through center crossing, northwardly left-hand rotation is sailed
Vehicle and pedestrian stop through small crossing, and in road east side in the south, the vehicle of waiting and pedestrian pass through center crossing left steering east
Road, by west sail Lai left turning vehicle and pedestrian turn left to the west side of road in the south, then road in the south is moved to by small crossing
The east side on road, pedestrian and non-motor vehicle reach the most east side of road by crossing.
As shown in Figure 10, when through vehicles begin through center crossing, also passed through by left turning vehicle on the lane of west
Small crossing.
As shown in figure 11, by west sail Lai left turning vehicle and pedestrian pass through the east side that small crossing moves to road in the south completely
When, road west side in the south is driven towards center crossing left turning vehicle and is waited with pedestrian by the east side that small crossing moves to road, this
When through vehicles also in passage；The pedestrian and non-motor vehicle come by the south is waited by the east side that crossing reaches road,
A circulation is constituted at this time.
As shown in figure 9, by east sail Lai non-motor vehicle and pedestrian turn around when, left turning vehicle pass through center crossing when,
By east sail Lai non-motor vehicle and pedestrian reach Accreditation Waiting Area 2 and wait, complete to turn around when through vehicles stop；By west sail Lai
Non-motor vehicle and pedestrian when turning around, through vehicles stop by when reach Accreditation Waiting Area 2 and wait, pass through center in left turning vehicle
