Abstract

The present invention discloses a traffic signal lamp set for divided lane control. Through addition of a traffic signal lamp at the crossing and the method of controlling the sequence of the traffic signal lamp, the vehicles passing the crossing are managed in order so as to improve the safety of pedestrians and vehicles passing through the crossing and greatly reduce the probability of traffic accident generation at the crossing. The universality is high, the large-scale refitting of the current traffic signal lamp is not needed, and the enforcement cost is low.

Description

The traffic signal light group that divided lane controls

Technical field

The present invention relates to a kind of traffic signal light group, it belongs to intelligent traffic administration system field.The present invention is directed to the traffic signal at crossing Lamp improves, and is effectively improved the vehicle safety by crossing, effective minimizing crossing traffic accident.

Background technology

Along with developing rapidly of economic construction, the generally raising of living standards of the people, automobile just strides forward general with unprecedented paces The family of the logical common people, particularly each big city in the world, automobile is the most significantly made a price reduction, and more have stimulated disappearing of city private car Take, particularly in China, according to scholarly forecast, the coming years China car owning amount by with annual 20% speed increase.

Along with the continuous growth of automobile quantity, traffic safety problem also becomes increasingly conspicuous.Learn, to 2012 from the Ministry of Public Security of China In the end of the year, whole nation vehicle guaranteeding organic quantity has reached 2.4 hundred million, is informed of a case and relates to the crossing traffic accident 4.6 ten thousand of casualties in the whole nation, 1.1 ten thousand people are dead, average every day 30 people, it may be said that the ratio of crossing traffic accident is sizable.

The traffic light installation method at crossing is broadly divided into two types at present, and a type is simple traffic light Controlling to turn left, passes through in the crossing in three directions of keeping straight on and turn right, another kind of type be three traffic light control respectively to turn left, Keep straight on and pass through in the crossing in three directions of right-hand rotation.During reality crossroad traffic signal lamp controls to pass through, particularly bigger Crossing, often occur when this direction traffic lights is transformed into green light by amber light, the current wagon flow tail in a upper direction is still also The most all by crossing, more some situation is the centre position that the pedestrian on crossing has just gone to this direction road, now originally The vehicle of direction multilane is started to walk the most simultaneously, and the compact car in outermost track is usually sheltered from road by the oversize vehicle of middle lane The road conditions of mouth dead ahead, are easy on the current wagon flow afterbody vehicle with a upper direction or crossing in starting refueling process Pedestrian collision, cause typical crossing traffic accident.

Summary of the invention

It is dull that the present invention mainly overcomes crossroad traffic signal lamp to arrange comparison, easily causes in vehicle start refueling process, with upper The safety problem of pedestrian collision on the afterbody vehicle of one traffic light direction wagon flow or crossing.

The present invention provides the traffic signal light group that a kind of divided lane controls, as it is shown in figure 1, the traffic signal light group of the present invention is at least Comprising two traffic light (1), each traffic light comprise signal lights (2) and reading the clock display screen (3)；Traffic light Between be separate setting.

Each traffic light in traffic signal light group control the current of a track respectively, as in figure 2 it is shown, hand at cross Cross road mouth, four direction wagon flow is east (E), south (S), west (W) and the north (N), the wagon flow in each direction respectively Having five tracks, outermost and inner side is two turning roadwaies respectively, and centre is three Through Lanes；The car in each direction Stream has a traffic signal light group to control, and is E ', S ', W ' and N ' respectively, and each traffic signal light group is outside road Toward internal sort traffic light sequence number, then traffic signal light group E ' there are E1, E2, E3, E4 and E5 to control five cars respectively Passing through of road, traffic signal light group S ', W ' and N ' are the most by that analogy.

According to the situation of crossing two way, the traffic signal light group on thing both sides and both sides, north and south is the most consistent, i.e. traffic Signal lights group E ' consistent with W ', S ' is consistent with N '.

Assuming that east-west direction wagon flow traffic signal light group E ' and W ' is red light, North and South direction wagon flow traffic signal light group starts conversion Become green light, then traffic light S1 and N1 is first transformed to green light, and rear every few seconds S2 and N2 also begins to be transformed into green light, Again minor tick after several seconds S3 and N3 be also transformed into green light, S4 and N4 is by that analogy.In this case, vehicle rises at crossing In step refueling process, outermost track vehicle head start refuels, when it strides across crossing stop line, it can be seen that crossing, left front Situation, if pedestrian is also in the middle of road on a upper direction wagon flow afterbody vehicle or crossing, it just can be safe and effective Dodge.When inside turn track prepare to be converted into green light pass through time, traffic light S2, S3, S4 and the N2 in craspedodrome road, N3, N4 are to terminate green light to be transformed into amber light and red light simultaneously, and the afterbody of such craspedodrome wagon flow would not have influence on inside turn car Road green light passes through.

North and South direction wagon flow traffic signal light group E ' and W ' change over condition is also similar with this.

The present invention can improve the safety that wagon flow is current at multilane crossing, is substantially reduced the vehicle accident at crossing；It addition, it is existing The improvement project that the crossroad traffic signal lamp of row is changed into the present invention is the most relatively simple, and cost is the lowest, and popularization is the highest.

Accompanying drawing explanation

Fig. 1 is the traffic signal light group schematic diagram of the present invention.

Fig. 2 is the crossing traffic schematic diagram of the present invention.

Fig. 3 is to pass through schematic diagram in the crossing of the present invention.

In figure, 1 is traffic light；2 is signal lights；3 is reading the clock display screen；N ' is by north orientation south signal lights group；S ' is Signal lights group from south to north；E ' is signal lights group from east to west；W ' is signal lights group from west to east；L is field of view lines.

Detailed description of the invention

As it is shown on figure 3, in the crossing of traffic signal light group of the present invention is installed, vehicle just waiting signal before the stop line of crossing Lamp passes through.For the vehicle A of crossing, because left side vehicle stops that it cannot prepare to know crossing, left side situation, dotted line in institute's figure L is field of view lines, on the left of it in the range of, vehicle A can't see, and now has pedestrian B to pass through on crossing Crossing has just been gone in the middle of road.

If common traffic light are arranged, now signal lights is transformed to green light and passes through, and the vehicle before stop line rises the most simultaneously Step, and the pedestrian in the middle of crossing is because of urgency and then quickly through crossing, vehicle A is in starting accelerator, because of left front Side's sight line is blocked, it is easy to clash into the pedestrian in running.

The traffic signal light group of the present invention just can well avoid situation about being similar to.When traffic light W2 is transformed into green light, W3 The most it is not transformed to green light, the vehicle in this track or halted state, and the track vehicle A starting that now W2 controls runs forward After, just can find that the pedestrian B on crossing is ready for quickly through crossing, vehicle A just can take dodging of necessity to arrange in time Execute, it is to avoid the generation of vehicle accident.
