Beneficial effects of the present invention are verified using following examples：
Embodiment one：
By taking the signalized intersections of Harbin as an example, its entrance driveway with two left-hand rotation dedicated Lanes, and the import are studied
There is a bus bus stop at 180m on the right side of road, as shown in Figure 2.
The basic condition of the entrance driveway is as follows：The track of entrance driveway 4, wherein 2 left-hand rotation dedicated Lanes, 1 Through Lane and 1
The straight right Shared Lane of bar；A length of 174s during the signal period, the entrance driveway signal timing dial has two phases, timing situation such as Fig. 3 institutes
Show；Peak hour traffic situation, as shown in table 1.Delay estimation emulates the side for coordinating video surveys to be combined using VISSIM
Method, take peak hour car load factor for 1.5 people/, bus load factor be 30 people/, the obtained entrance driveway is each
Delay per capita on direction, as shown in table 2,
The signalized intersections target inlet road peak hour traffic of table 1
The intersection target inlet road all directions of table 2 are delayed per capita
| Direction | Turn left | Straight trip | Turn right | It is average to be delayed per capita |
| Delay/s | 24.12 | 35.65 | 16.79 | 27.71 |
Meanwhile, the method that we use video surveys, having observed 60 cycles amounts to the left-hand rotation bus of 3 hours in public affairs
Hand over station to the left and road running situation.In this 60 cycles, there is left-hand rotation bus to be parked in rightmost side track and its tight
Waited on adjacent Through Lane properly can crossing gap to the left and road is so as to hindering the current situation of through vehicles to occur.
With reference to field observation situation, entrance driveway straight trip flow is very big, but left-hand rotation flow is comparatively small, stream of turning right
Amount is considerably less, and needs the bus bus stop at from intersection 180m to stop and must turn left in this intersection public
Hand over car it is more, therefore using the left turn lane right side is put be changed into through vehicles, the car that left-hand rotation bus and right-turning vehicles are shared
Road.
Here introduce a stand-by period T, represent left-hand rotation bus to the left and road during because through vehicles stop and
The total time waited in line.

In formula, t1、t2、t3、tnRepresent respectively each through vehicles because left-hand rotation bus stop wait in line when
Between.
The left-hand rotation bus of table 3 and through vehicles wait total duration
This two results show have two or more left turn lane to be respectively positioned on road for some entrance driveway most left
Side, but bus bus stop is on the right side of road, and station is not far far from intersection, and the public bus network that the station is stopped it is more and
When needing to turn left in intersection, the delay of left-hand rotation bus is obvious, and the delay is due to not conforming to for left turn lane position
What reason was caused.Not only reduce the traffic efficiency of left-hand rotation bus, and can allow left-hand rotation bus, straight trip and right-turning vehicles
Driver produces tired psychology because of mutually stopping, is unfavorable for easily driving, safety driving tips.
Now made improvements using method proposed by the invention：
According to physical condition, it is 5m to take distance of the traffic guide sign away from bus bus stop
According to formula, it is determined that the length of left-hand rotation Accreditation Waiting Area, left-hand rotation bus is in undersaturated condition, N heremaxTake 3
, LbusTake 15m；
G≥NmaxLbus=3 × 15=45m
According to formula, it is determined that left-hand rotation bus waiting area is with pointing out the distance between lane change graticule A, d takes 3m/s here2, TCTake
3s；
According to formula, pre-signal is determined away from 'STOP' line ahead L, here nmaxTake 25, LSTake 6m；Left-hand rotation bus speed
Degree V takes turning speed limit 30km/h, vehicle acceleration α to take 1.5m/s2, W takes 180m
Pre-signal straight trip long green light time TgTake 51s,
L≤nmaxLS=25 × 6=150m
L≤- the 13.5-45=91.5m of W-30-A-G=180-30
It is 91.5m to take L
T is asked according to formulaELAnd tSS, left-hand rotation bus speed V hereLTurning speed limit 30km/h is taken, its acceleration alpha takes
1.5m/s2
Take tELAnd tSSFor 21s；
T is sought further according to formulaESAnd tSLHere through vehicles speed VSSpeed limit 60km/h is taken, its acceleration d takes 3m/s2
Take tESAnd tSLFor 10s
Wherein need to ensure that last bus in left-hand rotation bus waiting area also can be green in main signal left-hand rotation direction
Lamp reaches intersection before terminating：tES+Tg≥tELI.e. 10+31 >=21, meet and require.
So far, each item data needed for this method is tried to achieve.Pre-signal timing is as shown in figure 4, intersection related facility is set
As shown in Figure 5.By the L of determination, G, tEL、tSS、tESAnd tSLIt is reflected in the intersection model using VISSIM, this method is entered
Row emulation, the crossing inlet road delay finally obtained is as shown in table 4, is delayed at bus lane-change as shown in table 5.
Crossing inlet road all directions are delayed per capita after table 4 is improved
| Direction | Turn left | Straight trip | Turn right | It is average to be delayed per capita |
| Delay/s | 16.73 | 33.45 | 19.34 | 24.10 |
Left-hand rotation bus and straight trip and right-turning vehicles wait total duration after table 5 is improved
| T/s | <20 | (20,40) | (40,60) | >60 |
| Periodicity | 60 | 0 | 0 | 0 |
| t/s | <30 | (30,60) | (60,90) | >90 |
| Periodicity | 2 | 14 | 28 | 16 |
As can be seen that the delay per capita of right-turning vehicles increased from delay table 4, through vehicles are delayed per capita have been subtracted
Few, the delay per capita of left turning vehicle is greatly decreased.The average delay per capita of the final entrance driveway reduces 3.61s (15.0%),
Effect highly significant, this traffic organization method also optimizes the arrangement operational efficiency of the intersection, has particularly given straight traffic
And the more running spaces of left-hand rotation bus, actual entrance driveway all directions path resource occupation rate more matches with its volume of traffic.
Meanwhile, as can be seen from Table 5, the time that left-hand rotation bus is waited because lane-change is obstructed on the track of the rightmost side is significantly
Decline, greatly improve the operation conditions of left-hand rotation bus, improve the left-hand rotation efficiency of left-hand rotation bus, this also will be very big
Improve left-hand rotation bus driver's mood, the national public traffic in priority policy of response.
