Abstract
The invention relates to advance left-hand steering and its driving method. According to the invention, two bidirectional-lane level crossings are arranged. Four unidirectional-lane separated roads (1) are disposed at the crossroad of the two level crossings. An advance left-hand steer waiting zone (2) is arranged at the level center of the separated level crossings. Steer waiting lanes for (3) are arranged in the steer waiting zone (2). A left-turn driving signal lamp (6) is mounted over a lamppost at each exit road. When driving at the entrance roads at the traffic light, through left-and-right-hand turning traffic flows can park to wait for green lights. When facing green lights, through right-hand turning traffic flows enter the crossings. After left-hand turning traffic flows wait to enter through right-hand steering crossings for 10-15 seconds and when the left-turn driving signal lamp turns green, the left-hand turning traffic flows enter the crossings and drive into the advance left-hand steer waiting zone (2), so as to wait for through traffic flows at another level crossings drive away from the crossings at the same time. There is no intersection conflict point when through left-hand turning traffic flows are at the same phased crossing. Through the design provided by the invention, the waiting time for green lights is short when vehicles are at the entrance roads, blowdown flow rate of automobiles is minimized, and it is safe for driving.

Be that the present invention puts a left side and running method the 1st specific embodiment mode thereof in advance shown in Fig. 1 example; Comprise two two-way lane usual friendship roads; Be provided with to execute at two two-way lane usual friendship road center pathway mouth places and draw four unidirectional track separate type usual friendship roads (1), and the yellow separator bar (6) of separate type road, be provided with to execute to draw at the crossing center of this separate type usual friendship road (1) and put left area to be transferred (2) in advance; In this area to be transferred (2), be provided with to execute and draw four and turn to and turn left to wait to make a detour (3); (3) separator bar of will waiting to make a detour is executed to draw and wherein is made up of solid line and dotted line, and one section places (3) the access end of waiting to make a detour for solid line (5), and another section is executed the only fare end that stroke dotted line (4) places wait to make a detour (3).(3) the separator bar setting of can also left-hand rotation being waited is executed and drawn each subtend respectively is a kind of color.The two ends setting is executed a stroke bicycle and is treated transposition (10) in the middle of (2) subtend two separator bars (12) in the area to be transferred.(2) are waited to make a detour to be provided with in the middle of (3) subtend two separator bars (12) to execute and are drawn a bicycle passage (11) in the area to be transferred.When waiting to change bicycle is introduced this and treat that transposition (10) ends in the fare.Between outside, area to be transferred (2) is with separate type usual friendship road yellow separator bar, locate to be provided with to execute and draw plane or the hot glove kerb shape sign of forming by black and yellow dichromatism.So that let central island cylindrical that the driver thinks road circuits seemingly.In each lamppost sky, place, exit ramp crossing left-hand rotation time zone signal lamp (7) is set.The lamppost sky is provided with bicycle time zone item lamp (14) in the middle of (3) subtend two separator bars (12) of waiting to make a detour; The place executes a stroke bicycle left-hand rotation entrance driveway (13) at nonmotorized vehicle lane (17) crossing, can be provided with to execute at left-hand rotation entrance driveway (13) front end and draw a bicycle Accreditation Waiting Area (15).Execute a stroke braking section (18) in separate type road (1) interlude setting.
Minimum area to be transferred (2) diameter does not wait from 60 meters of 15 meters of the path mouth diameters diameter to big crossing; Below put in advance left area to be transferred (2) wait to make a detour the length of (3) can be from little crossing the shortest several meters to big crossing the longest 55 meters do not wait; The car that can park cars within the minimum area to be transferred (2) unidirectional wait to make a detour (3) is that example is five; Maximum is 30; Above vehicle number is the vehicle in the one signal phase required left-hand rotation in the time of unidirectional track, does not comprise the other three-dimensional left turning vehicle in (3) of waiting to make a detour.Each signal phase time can be set 20 five seconds to six and not wait for ten seconds.Below not only do not establish the left rotaring signal phase time in addition, and craspedodrome signal one phase time, all shorter than original each crossing craspedodrome signal phase time.Craspedodrome green light one phase place hypothesis like two road intersections at original cross crossing place respectively was 50 times in second; With four phase places is example; Left-hand rotation green light one phase place of its two subtend respectively was 30 times in second, and its cycle should be and do not comprise the bright orange lamp time 160 seconds.And existing semi-circular crossing is that example need be a phase time 35 to 40 seconds only with the two phase signal, and its cycle should be for 70 to 80 times in second.Above crossing can be referred to as semi-circular crossing; There is not left turning vehicle to detour in each separate type usual friendship road (1) at this crossing; Have only through vehicles to cross the crossing in above road; Only the craspedodrome wagon flow is introduced this separate type road, separate type road (1) speed of a motor vehicle can be set 25 to 50 kilometre per hours.If the center, crossing under viaduct can be provided with to execute and draw two and turn left and wait to make a detour (3), its craspedodrome speed per hour can be set 50 to 80 kilometers.Like road central authorities the most suitable reconstruction in isolation strip more than the two lane highways width or newly-built is arranged, littler with original road circuits than taking up an area of, as at the crossing the especially big crossing of left turn traffic amount should not reconstruct in special hour.Most of crossing can be reconstructed or be newly-built in the city.
Running method: when the left three-dimensional wagon flow in a straight left side sails to place, above semi-circular crossing that entrance driveway ends within the fare, meet red light and can stop and wait for green putting, when green putting, straight right two started the crossing simultaneously to wagon flow.Pedestrian and bicycle can also get into the crossing after a little while and turn the right-hand rotation wagon flow at any time at crossing place, or wait for that bicycle and pedestrian are most of and cross after the crossing route mouth again and turn right.Left turning vehicle is parked in left-hand rotation entrance driveway (9) to be ended and to wait within the fare in the same way that straightgoing vehicle flows to after ten to ten five seconds of crossing, begins to drive into to put the straightgoing vehicle of in same phase time, waiting for another usual friendship road of next phase place once more in left area to be transferred (2) in advance and flow through the crossing and sail out of area to be transferred (2) and roll the crossing together away from same phase time.Can start in the time of can looking at the bright orange lamp of another usual friendship road cross place's craspedodrome signal lamp (16) when left turn traffic desires to sail out of this district in area to be transferred (2) straight; When straightgoing vehicle flow hour; Can ad hocly go out to distinguish signal lamp when the left-hand rotation flow is especially big, shift to an earlier date bright orange lamp control and let left turning vehicle roll area to be transferred (2) in advance away from.Left turn traffic advances (9) area to be transferred (2) limit in a green light phase time; All the other left turning vehicles that surpass this time should end at the left-hand rotation entrance driveway waits in the fare that green light is let pass next time; After the straightgoing vehicle of another usual friendship road flow to crossing ten to ten five seconds, left turn traffic began to wait for that next phase place is started with the craspedodrome wagon flow of another usual friendship road together and sail out of area to be transferred (2) and roll the crossing away from the above area to be transferred (2) of equally sailing in the same way.Left turning vehicle in area to be transferred (2) must all not sail out of this district within the equal time 15 to 20 seconds after another usual friendship road craspedodrome signal lamp gives a green light.Otherwise the left turning vehicle that can influence another usual friendship road enters this area to be transferred (2) waits for green putting.Straightgoing vehicle leans on the road kerb lane to go when flowing to after the crossing approaching exit ramp as far as possible, gives way as far as possible and rolls exit ramp smoothly away from the residue vehicle in area to be transferred (2).
Be that the present invention puts the first green light signals phase plane sketch map shown in left Fig. 1 example in advance shown in Fig. 2 example.Belt road two subtends straight right two to wagon flow from entrance driveway with waiting for that the two subtend left turning vehicles of putting in advance in the left area to be transferred (2) signal phase that coexists rolls the crossing away within the time.
Be that the present invention puts the second green light signals phase plane sketch map shown in left Fig. 1 example in advance shown in Fig. 3 example.Vertical road two subtends straight right two to wagon flow from entrance driveway with waiting for that the two subtend left turning vehicles of putting in advance in the left area to be transferred (2) signal phase that coexists rolls the crossing away within the time.
When brightening red light because of each craspedodrome green light; The craspedodrome wagon flow is sailed out of the crossing after the cutout of place, crossing end; (2) go out district's end through the area to be transferred earlier; End fare the place ahead through the craspedodrome entrance driveway then, so the green left turning vehicle starting time that puts of wait of ending within the fare in area to be transferred (2) waits for that than craspedodrome entrance driveway the green vehicle launch of putting will be earlier.Add the craspedodrome entrance driveway in addition and go out district's end apart from area to be transferred (2) stretch is arranged, the left-hand rotation of area to be transferred (2) vehicle launch is ahead sailed out of area to be transferred (2) and is rolled the crossing away from and afterwards sail to the area to be transferred (2) than craspedodrome entrance driveway vehicle launch and go out the district and hold and have the difference of eight to ten five seconds not wait.
When bicycle will turn left; When in the same way craspedodrome wagon flow when bright orange lamp forbade that the wagon flow cutout was promptly kept straight at the crossing; Also be that bicycle time zone signal lamp (14) is when giving a green light; Led by bicycle time zone leading line (8) from bicycle Accreditation Waiting Area (15) and to drive into into area to be transferred (2), the bicycle of sailing (2) other end to the area to be transferred through bicycle passage (11) treats that transposition (10) waits for that next phase place sails out of area to be transferred (2) and roll the crossing away from.
Above bicycle entering Accreditation Waiting Area (15) need be introduced into bicycle left-hand rotation entrance driveway (13) before and wait for after the most of crossing excessively of the non-vehicle flow of keeping straight in the same way; Drive in Accreditation Waiting Area (15) waits for that bicycle time zone signal lamp (14) gives a green light from left-hand rotation entrance driveway (13); Promptly be when keeping straight on the bright orange lamp of signal lamp in the same way, to concentrate the bicycle of waiting in the Accreditation Waiting Area (15) to begin to sail out of Accreditation Waiting Area (15).It sails out of Accreditation Waiting Area (15) time limit and all rolls Accreditation Waiting Area (15) away within five to ten seconds.Otherwise the straightgoing vehicle that can influence another usual friendship road flows to the crossing.Bicycle can also be kept straight on after the crossing with the craspedodrome bicycle and waited in other end Accreditation Waiting Area (15) and to keep straight on the crossing once more and turn left.
Above traffic organization is set with the shunting of the straight left and right sides of two phase signal controlling three-dimensional wagon flow at each crossing, does not establish the left rotaring signal phase time in addition.When the unidirectional number of track-lines in urban traffic road is six to ten, can its unidirectional number of track-lines be kept to five to eight now and be advisable, remaining track changes and is made as road-center isolation strip or reserve track or increases export number of track-lines and to alleviate exit ramp crowded.
