Description
Technical field
The present invention relates to a kind of control method of traffic channelling and traffic organization of grade crossing, belong to traffic design and traffic control field.
Background technology
The crossing is the throat and the hinge of road traffic, is again the bottleneck of road traffic, is the key factor of the decision City road traffic system traffic capacity, working time, traffic delay, operation efficiency and safety.In the crossing because the intersection of various flows between wagon flow, behavior such as interweave make the traffic characteristics more complicated of crossing; Wherein left turn traffic is maximum to the interference of other direction wagon flows; How on time and space, different wagon flows to be separated; How the different directions wagon flow being carried out rational traffic organization, is the key point that improves the crossing traffic efficiency.
In the right-angled intersection traffic organization of existing urban road plane, common have modes such as traffic circle and signal controlling intersection, in the traffic circle; Rotary island moves all directions wagon flow counterclockwise around the center, has effectively eliminated conflict point, and conflict is changed into interflow and shunting; Play a part to be positive in history, but its floor area is big, and the traffic capacity is not high; After vehicle flowrate increases to a certain degree, very easily cause traffic disturbance and block up; Signalized crossing separates the different directions wagon flow through traffic light signal in time, lets the different directions wagon flow at times through the crossing, has eliminated the conflict between wagon flow with this, makes traffic safety orderly.Its shortcoming is the increase along with the signal phase number, and the loss of signal time increases, and the wagon flow stand-by period prolongs, and traffic delay is big.The present invention effectively improves intersection capacity through the plane right-angled intersection being adopted a kind of new canalization and traffic organization method, reduces traffic delay, and more traditional traffic circle and signalized crossing traffic organization method have remarkable advantages.
Publication number CN1328314 discloses a kind of method that improves traffic throughput at cross of city ring roads, and track, stop line, signal lamp are arranged, makes the left-hand rotation car carry out twice parking, has avoided and straightgoing vehicle conflicting spatially; Then, carry out the signal phase design, the signal calculated cycle is carried out the timing conceptual design at times; At last, according to the flow different with the left-hand rotation car of keeping straight on, employing is opened early disconnected late or is opened the dynamically belt crossing of the control vehicle pass-through that breaks late morning.This method can not fundamentally change blocking up that the left-hand rotation car causes.
Summary of the invention
The objective of the invention is, low in order to solve in the organizational form of existing intersection the traffic capacity, the deficiency that traffic delay is big; The present invention discloses a kind of new grade crossing canalization and traffic organization method; This method is provided with four secondary waiting areas that supply different directions left-hand bend vehicle secondary stop-for-waiting through canalization is carried out in the crossing in the scope of crossing, efficiently solve the conflict of left-hand bend wagon flow to other direction wagon flows; Reduce the signal phase number of signal controlling; Improve the split of all directions signal, reduce traffic delay, improve the traffic capacity of intersection.
Technical scheme of the present invention is,
The right-angled intersection center sets out a center on the plane; The shape of center can be decided according to the concrete geometric condition of intersection; Commonly used have circle and a Long Circle, and four secondary waiting areas that supply different directions left-hand bend vehicle secondary stop-for-waitings are set in this center, and remainder can be made four greening islands; So that the different directions wagon flow is carried out canalization, can reach effect simultaneously to the crossing beautification and greening.The road surface is provided with the vehicle channelizing line around in the center, and guiding respectively flows to wagon flow and uses Correct Lane, and avoids making traffic safety orderly because of the unclear road occupying behavior of scrambling for roads that causes of graticule.
Based on all directions vehicle flowrate lane function of each inlet of crossing is divided, set out the left-hand rotation dedicated Lanes, craspedodrome dedicated Lanes and right-hand rotation dedicated Lanes also can be provided with based on needs and turn left to keep straight on the shared track and the shared track of keeping straight on of turning right.
Based on the crossing condition, the underground street passage of crossing can be set, zebra stripes also can be set on ground supply pedestrian and bicycle to cross the street.
Four different directions are provided with a cover signal lamp in the crossing; Every cover signal lamp comprises main signal light and auxilliary signal lamp two parts; Main signal light is arranged on the greening island place in each Parking Entrance the place ahead; In order to control the current of corresponding Parking Entrance wagon flow, supporting with it auxilliary signal lamp is arranged on subtend exit ramp place, in order to be controlled at the vehicle pass-through that wait secondary waiting area, center.
The two phase place signal controlling is adopted in the crossing: first phase place is the North and South direction green light; This moment is by king light and the auxilliary lamp of Nan Wangbei; Be green light by southern king light and auxilliary lamp, the vehicle of two Parking Entrances in north and south begins to pass through under king light control, and the vehicle of wherein turning right is directly turned right; Through vehicles behind the half cycle of center, gets into the subtend exit lane and sails out of the crossing counterclockwise; The left-hand bend vehicle, turns left to get into the parking of corresponding secondary waiting area and waits in line after 1/4th weeks around the center counterclockwise.Second phase place is the east-west direction green light, and be green light by the west toward eastern king light and auxilliary lamp by east king light and auxilliary lamp westerly this moment; At this moment; A last phase place is turned left by south (north) direction, and the vehicle of waiting in line in the secondary waiting area begins to keep straight under the control of the auxilliary lamp of west (east) direction and exit ramp sails out of the crossing from the place ahead; And the vehicle of two Parking Entrances of thing begins to pass through under king light control, and the vehicle of wherein turning right is directly turned right; Through vehicles behind the half cycle of center, gets into the subtend exit lane and sails out of the crossing counterclockwise; The left-hand bend vehicle, turns left to get into the parking of corresponding secondary waiting area and waits in line after 1/4th weeks around the center counterclockwise.
In to the signal timing dial process, should be according to the geometric condition and all directions vehicle flowrate distribution situation of intersection, confirm signal yellow time to avoid respectively flowing to interfering with each other between wagon flow.
The beneficial effect of the present invention and prior art comparison is; The present invention is through being provided with left-hand rotation secondary waiting area in the center, intersection; Make left-hand bend vehicle secondary stop-for-waiting in the secondary waiting area, made full use of the crossing path resource, effectively reduced the signal phase number; Reduced the traffic delay of vehicle, improved the traffic capacity and the traffic efficiency of intersection in the intersection; Be provided with clear and definite channelizing line in the crossing, effectively guide all directions wagon flow to take their own roads, make traffic safety orderly.
The present invention is applicable to the traffic channelling and the traffic organization of plane right-angled intersection.
