Scheme for quickly dispatching of motor-driven vehicles at level crossroads relates to urban road ruleization and traffic administration ambit.This scheme is provided with two revolution bends for certain distance before the crossing.The car that turns left at the crossing drives to the left side of Through Lane in the other direction, crossing in advance by the revolution bend.Solve original left-hand rotation car and opposite straightgoing vehicle travel direction and intersected contradiction.This scheme makes the left-hand rotation car of no thoroughfare direction wait for the situation that same motion puts in place that becomes by original assembly simultaneously, for accelerating the current condition of having created of this direction next time, has therefore accelerated dredging of vehicle.This scheme has the former crossing of basic maintenance situation, it is little to take up an area, make things convenient for the advantages such as bicycle and pedestrian, easy construction, small investment and range of application be wide, is applicable to construction and the transformation at main traffic crossing, big and medium-sized cities.

Description

Scheme for quickly dispatching of motor-driven vehicles at level crossroads

This invention relates to urban road ruleization and traffic administration ambit.

Urban traffic, especially city traffic are busy day by day at present.Because the quantity of motor vehicle and bicycle sharply increases, traffic intersection congested with cars phenomenon is more and more serious in the peak period.In order to accelerate the speed of dredging of place, crossing vehicle, taking many effective ways aspect road structure ruleization and the traffic administration.As build viaduct, widen the road surface to increase number of track-lines, will punish, adopt the flexible control signal lamp of computer, construction public subway and overpass etc. at the crossing along the motor vehicle that different directions travels when arriving the crossing.Viaduct is the most effective, needs fairly large pulling down and removing a building for reconstruction carried out at original crossing but build viaduct, and floor space is big, also just bicycle and pedestrian is brought inconvenience simultaneously.Required in addition expense height, construction period are longer.Therefore also should not be at all crossings, comprise that the T-shaped road junction all builds overpass bridge.

At plane crossing, the key that can vehicle faster be dredged is to solve the contradiction that left turning vehicle and opposite straightgoing vehicle travel direction are intersected.When a direction is that green light allows when current, if allow earlier the left-hand bend wagon flow turn left to travel, then the craspedodrome wagon flow on opposite still is in wait state and can not passes through, and vice versa.At this simultaneously, another does not allow the direction of passing through for red light, and the car that turn left is constantly assembled, waited for this moment.This just makes and takes turns to this direction when current next time, and left-hand bend wagon flow and craspedodrome wagon flow must wait for that mutually the situation of passing through is more serious.So repeatedly, more serious clogging might take place.Design and a kind ofly do not change original crossing structure substantially, obviously increase crossing vehicle handling capacity thereby solve above-mentioned contradiction, taking up an area of little, small investment, instant effect, the wide surface road structure of the scope of application again is purpose of the present invention.

The invention is characterized in apart from the suitable distance in former crossing, two suitably vehicle revolution bends of size are set.Fig. 1 dredges schematic diagram for road structure and vehicle that the present invention is used for the crossroad.In the frame of broken lines is block construction, is made up of two suitably big or small flower bed type garden dish revolution bends.Block construction can change according to actual conditions, as Fig. 2 for being staggered front to back arrangement garden winding mountain path, be applicable to place (the also only front and back arrangement that road is difficult for widening, not staggered), the right revolution bend shown in Figure 3 is an involute shape, the left side is the slalom course of less radian, when this structure Design is conceived to reduce the left turning vehicle revolution and the meeting angular separation of straightgoing vehicle, thus more successfully finish meeting.

Fig. 1 is instantiation of the present invention, and the crossroad direction arranges 8 flower beds altogether, certainly, if certain direction left turning vehicle is less, corresponding revolution bend can be set, can grasp flexibly according to actual conditions.Among the figure, track 1 and 7 is bicycle lane, and 2 and 6 is the right-turn lane, and 3 is the left turn lane, and 4 and 5 is Through Lane.Original path is 6 tracks, and the place, crossing changes 7 tracks into now.Each road is pressed 3 meters wide, 15 meters of flower bed diameters, and 6 meters in the track between the flower bed, the general proportions that flower bed is 50 to 100 meters apart from the crossing is drawn.Fig. 1 in order to give top priority to what is the most important, is provided with the speed car isolation strip of drawing.The motor vehicle that will turn left at the place, crossing drives on the track 3 through two flower bed garden winding mountain paths earlier, has namely driven in advance the left side with the reverse Through Lane 4 in crossing.Like this, when this direction, when allowing to pass through as the north-south, the motor vehicle that all travel directions are different does not disturb mutually, the car of promptly turning right 6 enters East and West direction track 2 from the track, left turning vehicle 3 enters East and West direction track 4 from the track, and straightgoing vehicle 5 enters track, opposite 4 from the track, and the right-hand bend bicycle 7 enters track 1 from the track.Meanwhile, the car that East and West direction will be turned left also continues to be rushed to the crossing and assembles and queue team and wait for unlike original crossing, but the portion of time of assemble waiting for is become time of motion, promptly also drive in advance on the East and West direction track 3, this just allows to have created when current as above-mentioned north-south situation same when current for next East and West direction.The vehicle that this road structure will turn left all directions can drive to track 3 around flower bed type garden winding mountain path at any time and get on.To sum up state as can be known, accelerated the speed of dredging of motor vehicle.

Because autos only is accelerated, and has also namely shortened traffic lights and has replaced the time, concerning the bicycle that will keep straight on and turn left, has also just shortened the stand-by period at the crossing.In general, stagger the morning in the peak period of motor vehicle and bicycle, is respectively 8-11 point and 7-8 point, overlap afternoon to be the 5-7 point, so the vehicle that present design more helps crossing, peak period in the morning dredged fast.Be flexible grasp, also can not allow bicycle to turn left.The bicycle that the turns left crossing, opposite of keeping straight on earlier waits for, when another direction allows the opposite of again keeping straight on when current, thereby finishes left-hand bend.Because traffic lights replace time shorten, so the time of the bicycle that turns left by the crossing can not prolong what yet,, to locate at the crossing for this reason, track 7 and 1 can suitably be widened.As long as wide 3 meters, high 2.8 meters get final product only around the bicycle underpass at crossing if open one, then can thoroughly solve the contradiction that motor vehicle and non-automotive vehicle direction are intersected, and the traffic capacity of motor vehicle greatly improves.

In addition, this scheme can be travelled by the tune of one of them garden winding mountain path motor vehicle, thereby provides bigger convenience for motor vehicle.

For traffic safety, to left turn lane 3 distinctive mark in addition, as lane line or the isolation strip of adopting other color, because 3 roads are very short, only have 50-100 rice, therefore can not bring how many troubles; Or in the track identification light etc. is established on both sides, 3 porch, also can indicate simultaneously the service time of garden dish bend, can not use at non-peak period.Passenger and changing trains for convenience, the setting of common electrical, bus stop is wanted rationally, the common electrical that continues to keep straight on, automobile, the station can be arranged on by the side before the crossing, turn right, before the station can be arranged on and turn or after turning all can, turn left, the station can only be located at before the flower bed slalom course or after turning left to finish after the flower bed slalom course of crossing other direction, i.e. the place slightly far away apart from the crossing.

Fig. 4 is a kind of T-shaped road junction design scheme.Be used for the T-shaped road junction, only two flower bed type garden winding mountain paths need to be set in one direction and get final product.This element structure also can adopt the form of structure of Fig. 1, Fig. 2 or Fig. 3.

The present invention compares with existing conventional crossing and viaduct has following advantage and good effect:

1. compare with existing crossing, can reduce congested with cars, accelerate vehicle and dredge speed, thereby save people's time, improve conevying efficiency, fuel saving and alleviate environmental pollution, it has also remedied the deficiency that conventional crossing vehicle can not be reversed end for end, and flower bed also can be used for beautifying urban environment in addition.

2. compare with viaduct, take up an area little, small investment, instant effect makes things convenient for bicycle and pedestrian, range of application is wide.
