Description
Technical field
The invention belongs to road traffic technical field, relate to a kind of intersection structure, particularly relate to a kind of plane intersection traffic structure.
Background technology
Intersection is as the important component part of approach system, and be the throat of road traffic, the various vehicle of road intersection and pedestrian will collect in crossing, conversion direction.Because people, car need to carry out traffic conversion at narrow space, make the traffic capacity of intersection less compared with section, easily cause traffic accident simultaneously.Show about have the traffic accident of 35% ~ 60% to occur on intersection according to traffic accident data both domestic and external.In addition, owing to being subject to red light impact, the delay time at stop of vehicle on intersection account for about 30% of omnidistance running time, wherein signal lamp incur loss through delay that the delay time at stop caused accounts for whole intersection delay time 60%.How to carry out intersection design and rationalization's traffic, to the speed of a motor vehicle and the traffic capacity that improve intersection, reduce vehicle and incur loss through delay, avoid traffic jam, reduce traffic accident and occur, ensure that intersection driving is unobstructed and have great importance.
Intersection traffic design comprises intersection geometry designs, track canalization, traffic organization and signal timing dial.In city, more common target cross lamp intersection, it has, and form is simple, sight line is good, traffic organization is convenient, the feature of land used economy.Its geometry designs generally adopts the straightgoing vehicle number of channels being less than or equal to section at entrance driveway, canalization 1 ~ 2 left-hand rotation dedicated Lanes, 1 exclusive right-turn lane, and exit ramp adopts identical with section or many one number of track-lines.
The signal timing dial of cross junction generally adopts combining form, and combination has pairing of keeping straight on, straight left pairing, mixing pairing three kinds.Wherein craspedodrome counterpart application is the most extensive, and its signal lamp generally adopts four Signal Phase Designs, first phase is that thing is kept straight on, second phase for the east of south, turn left to north, third phase is to keep straight in north and south, the 4th phase place is for reaching west, the left-hand rotation of north to east in the south.Right-hand rotation wagon flow and motor vehicle wagon flow Lothrus apterus point, be the independent flow direction, all can pass through within the whole signal period.The multiphase traffic time allocation of other target cross lamp intersections is then main according to each size flowing to the traffic volume, change on this basis and derivative.
Summary of the invention
In view of this, roundabout for the left turning vehicle direct lane to road intersection is waited to turn by the present invention, and when road intersection craspedodrome green light phase place and the through vehicles of road intersection pass through intersection simultaneously, thus improve the traffic organization ability of intersection, improve the capacity and level-of-service of intersection, beautifying city view, reduces construction costs.
