Abstract

The trafficking mode of motor vehicles featuring rapid left shift, left turn and simultaneous linear advancing belongs to the field of urban road traffic management. The invention mainly solves the problems caused by the management mode that linear advancing is exercised on road intersections with more than four-lane road at two directions and left-turning signal lamps are respectively arranged for realizing intersecting let through. The problems includes the following: traffic lane resources at the road intersections are not fully utilized, waiting time is much too long and signal lamps at the road intersections of straight line roads impede each other, which leads to road congestion. In the invention, the tactic of exchanging space with time is adopted, and road intersections provided with left-turning and linear advancing signal lamps arranged on the four-lane road at two directions are designed in an innovative manner; moreover, left-shift traffic lanes and left-shift signal lamps are added, the left-turning traffic lanes are reset, so that cars in the left-turning traffic stream of motor vehicles sequentially switch to the left to cross the through lane of other cars in the traffic stream, that is, the cars in the back drive to the leftmost left turn lane in order from the left backside of the cars in the front, then the cars can turn left; meanwhile, based on motion principle of objects, the trafficking mode featuring simultaneous advancing on linear roads is staged, which greatly improves road passing rate and achieves the purpose of smooth traffic.

Description

Motor vehicle " left-hand rotation that moves to left fast, straight line are advanced synchronously " passage mode

Technical field

Urban traffic management

Background technology

Craspedodrome is generally carried out in the above intersection of the two-way Four-Lane Road of current urban road and the left rotaring signal lamp is provided with respectively, the management mode that intersection is let pass.The wagon flow of all directions be allowed to average time by the crossing be total time section 1/4.And wait for that the time by the crossing is 3/4 of total period.Be 3 times of time of being allowed to pass through the average time that vehicle is waited for, and a plurality of tracks resource is wasted, so very easily initiation is blocked up.

In addition, the control of the signal lamp of each intersection of road is done things in his own way mostly, and is unrelated, this crossing often takes place is that green light is let pass and to be red light forbidden the crossing, front and back, the situation that each belisha beacon conditions each other on this road, the serious cruising that has hindered vehicle that disturbs.Increased the probability that blocks up artificially.

Summary of the invention

I exchange the time in the at first ingenious space that reasonably utilizes of motor vehicle " left-hand rotation that moves to left fast, straight line are advanced synchronously " passage mode of invention, innovative design more than two-way Four-Lane Road, set up separately to turn left and the intersection of craspedodrome signal lamp, set up the move to left track and the signal lamp that moves to left, reset left turn lane, after allowing left-hand rotation motor vehicle wagon flow sail leftmost left turn lane into, implement again from the track that moves to left traversing successively leap the other side's direct lane (back car is from the left rear side of front truck) order.In the whole process that moves to left, the wagon flow that moves to left takies the some position of the other side's direct lane, along with advancing of wagon flow, move backward apace, thereby promptly make way for the other side's wagon flow of keeping straight on, do not constitute the other side is kept straight on stopping of wagon flow, thereby make the wagon flow of turning left and keeping straight on and turning right be allowed to time, all significantly be promoted to and account for 1/2 of total time section from accounting for 1/4 of total time section by the crossing.Vehicle flowrate also just can correspondingly double.

Follow the object of which movement principle of science simultaneously, the current management mode that straight line is advanced has synchronously been released in supporting therewith design, has proposed each Signal on Highway Cross unification control of linear road curb line, lets pass synchronously and synchronous forbidden theory.(green light is a straight line road green light completely, guarantees to go everywhere without any hindrance here completely; Red light is a straight line road red light completely, and no through traffic to establish all fronts.) significantly promote the percent of pass of road, reach the purpose that the road is clear.(locking range is big more, and effect that the road is clear is good more)

In sum, I be sure of that the current management mode of motor vehicle " left-hand rotation that moves to left fast, straight line are advanced synchronously " will establish solid foundation for urban road is unobstructed.And dropping into very for a short time, simple and easy to do, have extensively far-reaching economic benefit and social benefit, also will be that Shanghai World's Fair in 2010 is created a well-regulated urban road traffic network.

The specific embodiment

Default with vertical road allow current 60 seconds, no through traffic, and 60 seconds (this is the belt road transit time) is one-period, and the implementation process of this passage mode is described.

1, after the belt road signal lamp was red entirely, promptly vertically road began to pass through.At first vertically road move to left and the left rotaring signal green light bright, allow the left-hand rotation motor vehicles from traversing successively leaps in track the other side direct lane that moves to left, after (back car is from the left rear side of front truck) order is sailed leftmost left turn lane into, enforcement left-hand rotation again.(vehicle that need give way and turn left or turn right and sail in belt road, the other side's vehicle has pas.As meet the other side track by chance and block up, the wagon flow that moves to left does not have the space to implement to move to left, and then left turning vehicle can be finished left-hand rotation routinely successively.) as shown in Figure 2.

2, move to left and the left rotaring signal green light is kept straight on after bright 5 seconds and the right turn signal green light is bright, allow to keep straight on and right-hand rotation vehicle pass-through (craspedodrome need be given way in the other side's vehicle that moves to left, and the vehicle that moves to left has pas).Move to left and the continuation of left rotaring signal green light, vertically road is current completely.As shown in Figure 3.

3, move to left the signal green light after 15 seconds (but proper extension is decided on wagon flow and highway section length) change red light, the track vehicle of forbidding moving to left moves to left, the sequence of cars of desiring to move to left stops at (keeping in line the front truck that has been moved to left by clearance) behind the track stop line that moves to left.Left turn lane signal green light continuity (left turning vehicle does not the hinder through vehicles to travel) green light of keeping straight on simultaneously and turn right continues.The craspedodrome The coast is clear.(, decide on the vehicle fleet size that needs to turn left in the default clearance program that can be repeated setting in preceding 30 seconds in 60 second period of letting pass in back 30 seconds.) vertically road turn left and the right turn signal lamp shifts to an earlier date 5 seconds and convert to red light than craspedodrome lamp, to the belt road vehicle headspace that moves to left.As shown in Figure 4.

4, vertically road all fronts signal red light is bright, forbids all vehicle pass-throughs of vertical road (the belt road vehicle repeats the current program of vertical road vehicle).As shown in Figure 5.

The corresponding measure of in implementation process, regulating and control at various complicated highway sections crossing

What must mention is: it much is that the transformation of effluent flow net landfill forms that the road in Shanghai has.The gauze skewness moves towards irregular road and occupies no small ratio.For alleviating the influence of multiple unfavorable factor to road, too short as the highway section, the road is narrow, and road connects and moves towards irregular, and the * type intersects or the like.The multiple measure of current employing of this type of road managed respectively be absolutely necessary: turn as restriction, no parking, adds the track, suitably prolongs or shorten clearance time or the like.

Example one is all east-west Fuxing Lu and Huai-Hai road and intersects, and is principle with the branch road main line of giving way then.Give way in Huai Hailu in the Fuxing Lu, and this crossing, Fuxing Lu situation opposite with other belisha beacons can only increase the appearance of vehicle amount with the track that increases this both sides, crossing road and alleviated and remedy.

The Huai Hailu of example two, Tibet Zhong Lu, Jin Linglu, Yan'an road one line, because Huai-Hai, Nanjing, crossing, Yan'an are at a distance of near excessively, the highway section that reservation Tibet road left turning vehicle is moved to left is too short, cause with the section road vehicle that moves to left and interfere with each other, so restriction is implemented at the crossing, Nanjing of centre turns left, and in advance 5-10 second open current in abdicating enough spaces and move to left for Yan Anlu, Huai-Hai road left turning vehicle, and can make the two highway sections vehicle that moves to left keep linking up and finish left-hand rotation smoothly and provide safeguard.

Example three, too short in the highway section, road network is overstocked and the Song Shan of the commercial location of bustling many cars such as Huai-Hai Zhong Lu, Huang Po, horse when, fresh water highway section and crossing, should take then to forbid that vehicle turns left even the unimpeded in order to the good current order of maintenance of this area guaranteed in no parking the series of measures of etc.ing of turning right.

Example four, then can adopt when arterial road are current to be accounted for 1/2 at special * word crossing (six cross road), branch road respectively accounts for 1/4 and deals with, and the track at also available in case of necessity increase branch road crossing increases traffic volume (changing the time with the space) as if as the foundation West Road level road mouth on Heng Shan road.

Example five, at the crossing of carrying out autos only " quick traversing left-hand rotation, straight line are advanced synchronously ", as be provided with nonmotorized vehicle lane, the bicycle measure that practicable secondary crosses the street of turning left solves.
