As the double-parking left-turn lane structure disclosed by the utility model is additionally provided with the second waiting area, the traffic capacity of the straight-going lane is greatly enhanced; and by virtue of the added left-turn pre-signal lamp, the traffic capacity and traffic safety at a road intersection are ensured.
Description
Technical field
The utility model relates to the traffic route technical field, relates in particular to a kind of twice parking left turn lane structure.
Background technology
As shown in Figure 1, a kind of track of the prior art structure, comprise left turn lane 1, direct lane 2, right-turn lane 3, be arranged on left turn lane 1 the place ahead treat row district 4.
This track structure has following defective:
1, a little less than the traffic capacity of direct lane 2.Because this track structure only comprises 1 direct lane, when the current flow of direct lane 2 is big, cause vehicle on direct lane 2, to be lined up easily.
2, left turning vehicle can't see signal light path.When the place ahead of left turning vehicle was big bus or big goods stock, the left turning vehicle that goes with car in the back was difficult to see signal light path.After the phse conversion of signal light path, the left turning vehicle that goes with car turns left in the red light phase place of signal light path, can disturb the current of belt road, has very big potential safety hazard.
Therefore, those skilled in the art is devoted to develop a kind of twice parking left turn lane structure to overcome above-mentioned defective.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provides a kind of twice parking left turn lane structure, so that the defective a little less than the traffic capacity of the direct lane of the track structure of prior art is improved.
Be to realize above-mentioned purpose, the utility model provides a kind of twice parking left turn lane structure, comprises left turn lane, is arranged on the direct lane on said left turn lane right side, and said track structure comprises that also first treats that row district, second treats the row district; Said first treats that the row district is arranged on the place ahead of left turn lane, and said second treats that the row district is arranged on the front portion of said left turn lane; Said second treats that row district and said first treats the row district continuously; Said first waits to go to distinguish leading portion, said second treats that front end, the rear end in row district all are provided with stop line; Said track structure comprises that also being arranged on said second treats the left-hand rotation pre-signal lamp in left side, row district; Said track structure comprises that also being arranged on said second treats the display board in left side, row district.
Preferably, said display board is the LED display board.
Preferably, said left-hand rotation pre-signal lamp, said LED display board all be arranged on said second treat the rear end stop line in row district the left side.
The beneficial effect of the utility model is:
Twice parking left turn lane structure of the utility model treated the row district owing to set up second, and through vehicles can be waited to go to distinguish through intersection via second, has greatly improved the traffic capacity of direct lane.
Owing to set up left-hand rotation pre-signal lamp; When the green light phase place deficiency of the signal light path of left turn lane in the time of 10 seconds; All vehicles can not get into second and treat the row district; To prevent that left turning vehicle from getting into second and treating that can't be trapped in second through intersection after row is distinguished treats to have guaranteed the traffic capacity and the traffic safety of intersection thus in the row district.
Below will combine accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is described further, with purpose, characteristic and the effect of understanding the utility model fully.

Fig. 5 is the vertical view of signal light path that the signal light path at direct lane embodiment illustrated in fig. 2 is red light phase place, the left turn lane track structure when being the green light phase place.
The specific embodiment
As shown in Figure 2, twice parking left turn lane structure one specific embodiment of the utility model, comprise left turn lane 10, be arranged on left turn lane 10 right sides direct lane 20, be arranged on the right-turn lane 30 on direct lane 20 right sides.
The track structure comprises that also first treats that row district 40, second treats row district 50.First treats that row district 40 is arranged on the place ahead of left turn lane 10, and second treats that row district 50 is arranged on the front portion of left turn lane 10.Second treats that row district 50 and first treats that row district 40 is continuous.First waits to go to distinguish 40 leading portions, second treats that front end, the rear end in row district 50 all are provided with stop line.The track structure also comprise be arranged on second treat the rear end stop line in row district 50 left-hand rotation pre-signal lamp 52, the LED display board in left side.
As shown in Figure 3, when the signal light path 54 of direct lane 20 is the red light phase place, when the signal light path 54 of left turn lane 10 was the red light phase place, left-hand rotation pre-signal lamp 52 was a red light, showed on the LED display board " through vehicles allow to get into treat row district ".Through vehicles can get into second and treat row district 50 at this moment, and left turning vehicle is treated to line up after row is distinguished the stop line of 50 rear ends second.
As shown in Figure 4, when the signal light path 54 of direct lane 20 is the green light phase place, when the signal light path 54 of left turn lane 10 was the red light phase place, left-hand rotation pre-signal lamp 52 was a green light, showed " do not allow through vehicles to get into and treat the row district " on the LED display board.Through vehicles can not get into second and treat row district 50 at this moment, and left turning vehicle can get into second and treat row district 50.
As shown in Figure 5, when the signal light path 54 of direct lane 20 is the red light phase place, when the signal light path 54 of left turn lane 10 was the green light phase place, left-hand rotation pre-signal lamp 52 was a red light, showed " do not allow through vehicles to get into and treat the row district " on the LED display board.Through vehicles can not get into second and treat row district 50 at this moment, and left turning vehicle is let pass.When the green light phase place deficiency of the signal light path 54 of left turn lane 10 in the time of 10 seconds; Show " do not allow vehicle to get into and treat the row district " on the LED display board; All vehicles can not get into second and treat row district 50; To prevent that left turning vehicle from getting into second and treating that can't be trapped in second through intersection after row distinguishes 50 treats to have guaranteed the traffic capacity and the traffic safety of intersection thus in the row district 50.
Twice parking left turn lane structure of the utility model treated row district 50 owing to set up second, and through vehicles can be waited to go to distinguish 50 through intersection via second, has greatly improved the traffic capacity of direct lane.
More than describe the preferred embodiment of the utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variation according to the design of the utility model.Therefore, all technician in the art according to the design of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in determined protection domain by claims.
