Description
Art：
The present invention relates to a kind of track setting of road plane intersection and corresponding traffic lights control method.Belong to traffic
Engineering discipline.
Background technology：
Because the vehicle that each phase place is let pass can only be in turn using the road surface space of grade crossing, grade crossing becomes
The Main Bottleneck of restriction road passage capability.At present, the known track setting to intersection and the clearance to vehicle, main
Follow the method for being spatially separating and temporal separation method.I.e.：Allow enter vehicle before crossing by turning around, turn left, keep straight on, public transport, the right side
Turn and respectively enter guided vehicle road, not clash as principle, allow them pass through crossing in the time of regulation and space respectively.For
Adapt to the growth of transport need, when design (containing newly-built and reconstruction) intersection, have taken up center shielding wire left avertence, contracting
Subtract the measure such as guided vehicle road width and broadening road surface to increase the guided vehicle road entering crossing, and take " left-hand rotation car area to be driving "
Etc. making full use of crossing space, also take and prolong macrocyclic method to increase split ... but these measures not from
The potentiality at most crossing are dug on room and time.Such as：Although the guided vehicle road entering crossing is existing a plurality of, take turns to specifically a certain
When phase place is passed through, its corresponding guided vehicle road is still inadequate, or, even if the enough entrance guided vehicle roads of each phase place, but
Its corresponding exit lane is not enough, and their essence is exactly that the traffic flow being cleared is not used the space in crossing central authorities
Foot.These deficiencies are particularly evident when left-hand rotation, the phase place that turns around or primary and secondary road intersect.
Content of the invention：
The present invention still follows the method for being spatially separating and temporal separation method.In order to overcome enter crossing guided vehicle road inadequate,
The traffic flow that exit lane is not enough, be cleared is not the defect of the space foot at crossing, the invention provides a kind of road
The track setting of grade crossing and corresponding traffic lights control method.The method satisfaction is kept straight on, turns left, turning right, reversing end for end
Transport need, can allow the number of track-lines that straight, the left phase place of each clearance in crossing is passed through reach most on the basis of equilibrium, and favorably
In public traffic in priority and facilitate pedestrian.
The technical solution adopted for the present invention to solve the technical problems is：In terms of the arrangement of crossing space, regardless of primary and secondary road
Road, in the broadening section of track, allow entry position each let pass straight, left phase bit occupancy into and out of track quantity keep equal
(i.e.：No matter straight trip or left-hand bend phase place, no matter relative or adjacent entries, whether enter the track at crossing or roll away from
The track at crossing, all allows to be cleared the spendable number of track-lines of vehicle equal, when condition is impermissible for, at most differs a track)；?
Entrance lane is divided into entrance guided vehicle road, peripheral guided vehicle road and public transport and right-turn lane three part (i.e.：Stop in every entrance
Set up one peripheral stop line and peripheral traffic lights after line, be guiding arrow straight and turning left and u-turn guided vehicle road cutting
Different two sections, leading portion is referred to as " entrance guided vehicle road " back segment and is referred to as " peripheral guided vehicle road ", arranges preferential buses to lead to simultaneously
The road surface of row and the smooth passage by intersection of right-hand rotation car).Use these methods, a variety of deficiencies for making up original lay sky
Between basis.Corresponding traffic lights control measure are that, in " entrance " and " peripheral " position, it is right to rotate by the transverse axis of direction of advance
Claim (pressing crossing central rotation symmetrical) to arrange lamp group, signal group and phase place, then follow the prescribed rules in another axle again；In entrance master
Run first keep straight on second keep straight on first turn left (containing u-turn) second turn left (containing u-turn) phase place (" first " represents south with
The north to when, " second " represents east and west direction, and vice versa, " turn left (containing u-turn) " i.e.：Turn left and u-turn one phase place of synthesis,
Also be sometimes expressed as in this manual " turn left and reverse end for end ", hereafter all with)；Allow every place periphery traffic lights alternate run simultaneously
Two phase places that straight traffic advances, (containing the u-turn) Herba Plantaginis that turn left enter, also arrange instruction if necessary in each periphery traffic light right
Change trains or buses and buses directly pass through evergreen lamp group (or sign board) and " electronic police "；By how many decisions of left turning vehicle be with
Whole or half way by units of control the clearance of street crossing.So, just support as stated above arrange track when, entrance
The traffic flow that each phase place of position is let pass is to greatest extent in turn using the space in crossing central authorities.
The invention has the beneficial effects as follows：Meet the transport need keeping straight on, turn left, turning right, turning around, make crossing each straight, left
The number of track-lines that phase place is passed through reaches most on the basis of equilibrium；Also provide buses in the section not setting dedicated bus lanes
Preferentially near the condition at crossing；It has been flexibly utilized by street crossing.Thus in transport need one timing, phase place and week can be shortened
Phase, or in phase place and cycle one timing, the traffic capacity at crossing can be improved.

Specific embodiment：
(taking crossroad as a example, the item not referred to follows country's technical specification relevant with industry)：
When the grade crossing that traffic lights control is carried out in design (containing newly-built and reconstruction), regardless of primary and secondary road, on road
In mouthful broadening section, the track quantity of entrance and exit of each clearance phase place is allowed all to keep equal.When condition does not allow, at most only
A track can be differed.Its method is based on the section close to crossing of broadening subsidiary road and branch road, distributes equally each straight, Zuo Xiang
Position into and out of number of track-lines.(in the embodiment of Fig. 1 and Fig. 4, each entrance guided vehicle road all has 4 straight trip arrows, 4 left-hand rotation arrows
Head, the outlet of head end operation, it is located at the center shielding wire on the left of entrance guided vehicle road.Let pass respectively when entrance and keep straight on or turn left
During (containing u-turn) phase place, vehicle all has 4 tracks can enter crossing, and corresponding exit lane has 5, and wherein 1 is to turn right
Exit lane, the vehicle that remaining 4 entrances that can pass through are straight, left-lane clearance comes.)
Design each important document at crossing by relevant specification and current conditions, including curb contour line, center shielding wire, guiding
Track, exit lane, bicycle lane, entrance stop line, pedestrian and non motorized vehicle zebra crossing, various sign board, signal lighties etc.
Deng.
At the center at crossing, apply lines or the channelizing line of picture each entrance left-hand bend vehicle.
Push away certain distance from each entrance parking line position backward, then a cut-out straight trip is set, turns left and u-turn guiding
The peripheral stop line (not cutting off buses special lane and right-turn lane and bicycle lane) in track.This peripheral stop line and entrance
Stop line apart from treatment in accordance with local conditions, typically take the length that 10 dollies are queued up, can use original guided vehicle road one when reconstructing crossing
Half length, also can use the distance of crossing two entrance stop lines of relative direction, also can by this crossing spacious when motor vehicles 3 seconds
The distance of wheeled.
Peripheral traffic lights group and " electronic police " are set before peripheral stop line.
Allow and between entrance guided vehicle road and peripheral stop line, vacate one section of distance that vehicle can be allowed to select track.
Entrance guided vehicle road before peripheral stop line, presses straight trip and u-turn, straight and turning left, buses from left to right

Quantity, determines with possible, have can set more, and have can be zero on demand, and such as buses turn left and buses straight trip.No
If special guided vehicle road that buses turn left and buses are kept straight on, left, straight trip buses and other vehicles are used in mixed way (except right-hand rotation
Outside guided vehicle road) two, side guided vehicle road of keeping right.(i.e.：Buses turn left, buses straight trip is become by dedicated bus lanes
The left-hand rotation being used in mixed way with other vehicles, Through Lane, public transit vehicle is preferentially directly entered, and other vehicles stop through periphery
Fare sees that lamp enters.In the embodiment of Fig. 1 and Fig. 4, (containing u-turn) vehicle of keeping straight on or turn left, in different phase places, position is entered respectively
After entering " entrance guided vehicle road ", 4 tracks can be exclusively enjoyed.)
Peripheral guided vehicle road after peripheral stop line, by turn left and u-turn, straight trip, buses special, turn right and non-
The species such as car lane apply picture guiding arrow or mark.The quantity of every kind of guided vehicle road, determines with possible, Ke Yiwei on demand
Zero, such as buses special lane.Do not set buses special lane, buses and other vehicles are used in mixed way right-hand rotation guided vehicle road.
The length treatment in accordance with local conditions of peripheral guided vehicle road, can be more slightly longer than entrance guided vehicle road above, is typically set to so
Length：Allow every vehicle stopping in this guided vehicle road once, crossing can be passed through within this cycle.
When straight trip, left-hand rotation and head end operation close periphery guided vehicle road, see that first arrow signal lamp is stopped by periphery
Line, then see that second arrow signal lamp passes through crossing.Directly, left lateral buses are only controlled by entry signal lamp.Right-turning vehicles one
As let pass by evergreen lamp.
In order to not clash with street crossing lamp, the evergreen lamp that right-turning vehicles pass through is commanded not set at crossing.
The position corresponding to center shielding wire in every street crossing lateral road arranges the safety island (distance away from crossing center for the safety island
Determine according to the leftmost two left-hand rotation channelizing lines of adjacent entries).Pedestrian and non motorized vehicle sees that lamp passes through lateral road.Non-motor vehicle turns left
Carry out and cross the street twice.
At the crossing more than left turning vehicle, every lateral road is divided into two sections with 4 lamp groups, 4 lateral roads are divided into 8 by 16 lamp groups
Section, the not only opening lateral road parallel therewith when phase place kept straight on by two motor vehicles, and in two motor vehicles left turn phases,
Also piecewise utilizes lateral road.Second embodiment be：At the few crossing of left turning vehicle, every lateral road with 2 pedestrian's lamp groups, 4
Bar lateral road using 8 pedestrian's lamp groups, only opens lateral roads parallel therewith in 2 straight trip phase places altogether.

Before stop line, there are commander's left-hand rotation (containing u-turn), straight trip, the lamp group turned right, before peripheral stop line, have commander to keep straight on and left
Turn the lamp group that (containing u-turn) vehicle advances in turn, and the lamp group that instruction buses are directly advanced with right-hand rotation car.These lamp groups can
To arrange one by one by track, can arrange it is also possible to not set one by one in direction in accordance with the instructions, such as public transport and right-hand rotation lamp group.
Entrance stop line and the signal group of peripheral stop line, first press rotationally symmetrical (the Ji An center rotation of transverse axis of direction of advance
Turn symmetrical) arrangement, then rotate 90 ° and follow the prescribed rules on the second axis.Taking North and South direction as a example：Stop in south, north two entrances
Before line, there is the signal group that commander's vehicle that north and south shares is kept straight on, have the letter of the shared commander's vehicle left-hand rotation (containing u-turn) in north and south
Number group, there is the signal group that commander's right-turning vehicles that system-wide mouth all shares pass through；Before peripheral stop line, there is the finger that north and south shares
Wave the signal group of left-hand rotation (containing u-turn) vehicle advance, have the shared signal group of commander's through vehicles advance in north and south, have system-wide mouth
The evergreen signal group that instruction right-hand rotation (containing the public transport) vehicle all sharing directly passes through.Then east and west is to also so symmetrically setting
Put their shared signal group.
The same with signal group, phase place is also the first transverse axis rotationally symmetrical (i.e. symmetrical by crossing central rotation) by direction of advance
Arrangement, then rotated ninety degrees are followed the prescribed rules on the second axis.
In one cycle, entry position only sets four phase places：First straight trip, first are turned left (containing u-turn), second is kept straight on, second is turned left
(containing u-turn), the phase sequence of operation is mainly first straight trip second straight trip first left-hand rotation (containing u-turn) second and turns left (containing u-turn)
(respectively changing trains or buses to the right typically to be let pass by evergreen phase place, similarly hereinafter).
In one cycle, each periphery traffic lights alternate run advances by straight traffic, allows left-hand rotation (containing u-turn) Herba Plantaginis to enter
Two phase places.After the through vehicles in above entrance guided vehicle road are covered, put with that left-hand rotation (containing u-turn) vehicle enter into
Mouth guided vehicle road, vice versa.(turn right and buses directly passed through by the instruction of evergreen lamp group, similarly hereinafter).
In one cycle, when entrance clearance first straight trip phase place when, Party B to peripheral traffic lights just allow through vehicles enter
Entrance guided vehicle road；When taking turns to entrance clearance second straight trip phase place, Party A to peripheral traffic lights just allow left-hand rotation (containing reverse end for end)
Vehicle enters entrance guided vehicle road；When take turns to entrance clearance first turn left (containing u-turn) phase place when, the peripheral traffic lights of second also allow a left side
Turn (containing u-turn) vehicle and enter entrance guided vehicle road；When take turns to entrance clearance second turn left (containing u-turn) phase place when, Party A to outer
Enclose traffic lights allows through vehicles enter entrance guided vehicle road again.
