Abstract
The invention belongs to the field of traffic construction. A road intersection comprises left-turn hairpin roads, passages, traffic lanes, traffic lights, signs and traffic lines. According to the left-turn hairpin, a turn hairpin curve road is arranged at each upper right corner of the road intersection, and left-turn lanes in a conventional intersection are canceled. A vehicle to turn left can pass by the road intersection and then turn right into the left-turn hairpin road so as to enter the left-turn road. The invention provides a method of reducing traffic conflict points at an intersection and raising traffic safety and trafficability by simple reconstruction of a road intersection.
Description
Technical field
The invention belongs to transport development field, especially relate to the method to set up of a kind of intersection.
Background technology
Nowadays urban traffic blocking situation is very serious, and particularly urban road intersection, is the key point blocked up.At present, intersection is divided into three major types: the first kind is level-crossing, and road intersects in approximately the same plane, and traffic safety and the traffic capacity depend greatly on the traffic organization of crossing, and shortcoming is easily to block.Equations of The Second Kind is traffic circle, arranges a bigger rotary island of area in the middle of crossing, and vehicle is interleaved into circuit, travels around island.Shortcoming is that floor space is big；Vehicle must detour；The volume of traffic easily blocks when increasing；Pedestrian traffic inconvenience.3rd class is traffic interchange, and mutual afoul wagon flow is arranged on the road of different elevation intersection respectively that be crossed to form.Shortcoming is structure complexity, takes up an area big, and quantities and investment are big, and difficulty laid by avenue.
Summary of the invention
The purpose of the present invention is intended to, by the transformation to current road grade crossing, improve traffic safety and the traffic capacity of road grade crossing.
More than technical problem is that and solved by following technical proposal: a kind of intersection, constitute including left-hand rotation hairpin curve track, passage, runway, traffic light, mark and graticule.Described left-hand rotation hairpin curve track refers to arrange a hairpin curve track in the intersection upper right corner, replace the left turn lane of conventional cross mouth, the vehicle turned left in longitudinal track uses craspedodrome right-hand rotation to walk hairpin curve track, keeps straight on subsequently into horizontal track and realizes.
As preferably, described a kind of intersection can arrange several left-hand rotation hairpin curve tracks according to crossing form and vehicle flowrate.One left-hand rotation hairpin curve track is often set and can reduce three, crossroad conflict point, nine, five fork in the road conflict point.
As preferably, described a kind of intersection does not has left turn lane, and the vehicle of left-hand bend uses 270 ° of replacement former left-hand rotations 90 ° of turning right of keeping straight on, and makes all vehicles travel to clockwise direction.
As preferably, the passage of described a kind of intersection includes bicycle lane and footpath, and its effect is to cross bicycle lane and car lane for pedestrian, crosses car lane for bicycle.
As preferably, the left-hand rotation hairpin curve track of described a kind of intersection and passage have usual friendship and grade separation two kinds.Usual friendship refers to that left-hand rotation hairpin curve track and passage intersect in approximately the same plane；Grade separation refers to that left-hand rotation hairpin curve track and passage intersect on the road of different elevations, and grade separation can solve motor vehicles, bicycle and pedestrian Ge Hangge road, it is ensured that safety.
As preferably, the signal lights of described a kind of intersection only has stop and go signal, simplifies signal control, shortens the sigtnal interval.
As preferably, the direction board of described a kind of intersection is only kept straight on and is turned right and later indicates, makes all vehicles travel to clockwise direction.
The present invention has an advantage that comprehensive 16, Neng Jiangyuan crossroad, the left-hand rotation hairpin curve track conflict point that arranges in crossing reduces to 4, and 50 conflict points in former five fork in the road reduce to 5, makes all vehicles all travel to clockwise direction, improves traffic safety.Intersection, respectively to all Through Lanes, shortens Accreditation Waiting Area length, can start to walk to pass by one's way to track rolling stock simultaneously, improve crossing handling capacity.Driving vehicle is all kept right and has been turned without lane change to the left, change vehicle heading, improve traffic safety before entering crossing.The not yet done driver of road need not select route in advance, it is to avoid going to the wrong way crossing will be around great circle.Traffic light only control vehicle and stop and current, simplify signal and control, shorten red time.Being conducive to implementing urban public transportation lane, public transit vehicle is few, and vehicle is big, can turn left routinely when green light.
Accompanying drawing explanation
The signal of Fig. 1 existing road grade crossing and left-hand bend vehicle trajectory diagram.
The signal of Fig. 2 intersection of the present invention and left-hand bend vehicle trajectory diagram.
In figure: left-hand rotation hairpin curve track 11, passage 12, Through Lane 13, left turn lane 14, right-turn lane 15, bicycle lane 16, footpath 17, traffic light 2, aerial direction board 3, roadmarking 4, vehicle 5 and Lutao 6.There are usual friendship 111 and grade separation 112 in left-hand rotation hairpin curve track 11 and passage 12 cross point.Through Lane 13 has longitudinal track 131 and horizontal track 132.Traffic light 2 have red light 21, green light 22, Lamp with timer 23, left-hand rotation arrow lamp 24, craspedodrome arrow lamp 25 and right-hand rotation arrow lamp 26.Aerial direction board 3 has left-hand rotation mark 31, craspedodrome mark 32, right-hand rotation mark 33 and later mark 34 of turning right.
Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings:
Seeing Fig. 2, a kind of intersection, including left-hand rotation hairpin curve track 11, passage 12, Through Lane 13, bicycle lane 16, footpath 17, traffic light 2 and aerial direction board 3.Left-hand rotation hairpin curve track 11 refers to arrange a hairpin curve track in the intersection upper right corner.Left-hand rotation hairpin curve track 11 and passage 12 intersect usual friendship 111 and grade separation 112, and grade separation 112 has viaduct, and vehicle travels on viaduct, and pedestrian and non motorized vehicle passes through under viaduct.Face method below the left-hand bend vehicle of crossing completes: when longitudinal track 131 green light 22 is bright, craspedodrome and left turning vehicle all straight forward on track cross horizontal track 132, left-hand bend vehicle is kept to the right, turn right and enter left-hand rotation hairpin curve track 11, turn 270 ° and wait craspedodrome when green light 22 is bright to horizontal track 132.
