Beneficial effects of the present invention are verified using following embodiment:
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: 4 lane of entrance driveway, wherein 2 left-hand rotation dedicated Lanes, 1 Through Lane and 1
Item directly right Shared Lane；A length of 174s when the signal period, there are two phase, timing situation such as Fig. 3 institutes for the entrance driveway signal timing dial
Show；Peak hour traffic situation, as shown in table 1.The side that delay estimation is combined using VISSIM emulation cooperation video surveys
Method, take peak hour car load factor be 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
2 intersection target inlet road all directions of table are delayed per capita
| Direction | Turn left | Straight trip | It turns right | It is average to be delayed per capita |
| Delay/s | 24.12 | 35.65 | 16.79 | 27.71 |
Meanwhile we have observed the left-hand rotation bus of total 3 hours in 60 periods in public affairs using the method for video surveys
Hand over station to the left and the operating condition in road.In this 60 periods, there is left-hand rotation bus to be parked in rightmost side lane and its tight
Waited on adjacent Through Lane properly can crossing gap to the left and situation of the road to hinder through vehicles current occurs.
In conjunction with field observation situation, entrance driveway straight trip flow is very big, but in contrast left-hand rotation flow wants small, stream of turning right
Measure it is considerably less, and need from the 180m of the intersection at bus bus stop stop and must this intersection turn left public affairs
It hands over vehicle more, therefore becomes the vehicle that through vehicles, left-hand rotation bus and right-turning vehicles share using the left turn lane right side is set
Road.
Here introduce a waiting time T, indicate left-hand rotation bus to the left and road during because through vehicles stop due to
The total time waited in line.
T=T1+T2+T3+…+Tn

In formula, t1、t2、t3、tnRespectively indicate each through vehicles because left-hand rotation bus stop due to wait in line when
Between.
3 left-hand rotation bus of table and through vehicles wait total duration
This two the result shows that, there is two or more left turn lane to be respectively positioned on road some entrance driveway most left
Side, but bus bus stop is on the right side of road, and station ion-exchange prong is not far, and it is more in the public bus network that the station is stopped and
It needs when intersection is turned left, the delay of left-hand rotation bus is obvious, and the delay is not conforming to due to left turn lane position
Caused by reason.The traffic efficiency of left-hand rotation bus is not only reduced, and can allow left-hand rotation bus, straight trip and right-turning vehicles
Driver generates tired psychology because of mutually stopping, and is unfavorable for easily driving, safety driving tips.
Now made improvements using method proposed by the invention:
According to physical condition, taking distance of the traffic guide sign away from bus bus stop is 5m
According to formula, the length of left-hand rotation Accreditation Waiting Area is determined, left-hand rotation bus is in undersaturated condition, N heremaxTake 3
, LbusTake 15m；
G≥NmaxLbus=3 × 15=45m
According to formula, the distance between left-hand rotation bus waiting area and prompt lane change graticule A are determined, d takes 3m/s here2, TCIt takes
3s；
According to formula, determine pre-signal away from 'STOP' line ahead L, n heremax25 are taken, LSTake 6m；Left-hand rotation bus speed
Degree V takes turning speed limit value 30km/h, vehicle acceleration α to take 1.5m/s2, W takes 180m
Pre-signal straight trip long green light time Tg51s is taken,
L≤nmaxLS=25 × 6=150m
L≤- 30-13.5-45=91.5m of W-30-A-G=180
Taking L is 91.5m
T is sought according to formulaELAnd tSS, left-hand rotation bus speed V hereLTurning speed limit value 30km/h is taken, acceleration alpha takes
1.5m/s2
Take tELAnd tSSFor 21s；
T is sought further according to formulaESAnd tSLHere through vehicles speed VSSpeed limit value 60km/h, acceleration d is taken to take 3m/s2
Take tESAnd tSLFor 10s
Wherein need to guarantee that last bus in left-hand rotation bus waiting area also can be green in main signal left-hand rotation direction
Lamp reaches intersection: t before terminatingES+Tg≥tELThat is 10+31 >=21 are met the requirements.
So far, all data needed for acquiring this method.Pre-signal timing is as shown in figure 4, intersection related facility is arranged
As shown in Figure 5.By determining L, G, tEL、tSS、tESAnd tSLBe reflected in the intersection model using VISSIM, to this method into
Row emulation, the crossing inlet road delay finally obtained are delayed as shown in table 5 as shown in table 4, at bus lane-change.
Crossing inlet road all directions are delayed per capita after table 4 improves
| Direction | Turn left | Straight trip | It turns 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 improves
| 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 to be 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 optimize the arrangement operational efficiency of the intersection, have especially given straight traffic
And the more running spaces of left-hand rotation bus, practical 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 lane of the rightmost side is substantially
Decline, greatly improves the operation conditions of left-hand rotation bus, improves the left-hand rotation efficiency of left-hand rotation bus, this also will be very big
Left-hand rotation bus driver's mood is improved, national public traffic in priority policy is responded.
