Description
Technical field
The utility model relates to urban road junction field of traffic control, especially relates to a kind of piggybacking and turns left to get over line suggestion device.
Background technology
Intersection is as the key node in urban traffic network, and its smoothness, safety have vital effect to city road network trouble-free operation.Turning to of wagon flow and the behavior such as conflict, intersection, shunting, interflow between the various wagon flows caused make the traffic characteristics more complicated of intersection, and intersection often becomes the key point whether urban traffic passes unimpeded.Intersection left turn traffic is the principal element producing conflict point, and irrational left turn traffic tissue can make intersection efficiency decline, and the delay time at stop is long, and vehicle queue causes obstruction to traffic, and toxic emission aggravates.Therefore, no matter be the capacity and level-of-service improving intersection, or ensure traffic safety, reduce motor vehicle exhaust emission, the science organization of left turn traffic is all most important.During existing intersection accidents tissue and signal control, in order to ensure the current smoothly of left turn traffic, the means usually adopted have: arrange exclusive left-turn lane, increase left turning vehicle transit time etc.The crossing more for left turning vehicle or intersection traffic pressure is larger, the exclusive left-turn lane arranged by broadening often can not meet current demand.But existing left turn lane does not get over line suggestion device, driving is caused to occur dangerous.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of piggybacking improving left-turning traffic safety and turns left to get over line suggestion device, and the technical scheme of employing is as follows:
Piggybacking turns left to get over line suggestion device, comprise left turn lane, direct lane, left-hand rotation stop line, isolation strip and left-hand rotation district, described left-hand rotation district and left-hand rotation stop line junction are provided with the first earth magnetism detector, stage casing, described left-hand rotation district is provided with the second earth magnetism detector, described first earth magnetism detector and the second earth magnetism detector are strip, described first earth magnetism vehicle sensors is parallel with left-hand rotation stop line, described second earth magnetism vehicle sensors is miter angle with driving stop line, described isolation strip is provided with wireless launcher, wireless launcher is electrically connected with the first earth magnetism detector and the second earth magnetism detector, described left turn lane diagonal angle place is provided with a LED notice board, described LED notice board and wireless launcher wireless connections.
Further, described LED notice board is red text notice board.
Further, described LED notice board is located at the right corner in track in opposite directions, and described LED notice board and left-hand rotation stop line are miter angle.
Adopt above-mentioned piggybacking left rotaring signal lamp control device, left rotaring signal can not opened when left turn lane does not have vehicle, ensure that the traffic efficiency of road.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that piggybacking turns left to get over line suggestion device.
Detailed description of the invention
Piggybacking turns left to get over line suggestion device as shown in Figure 1, comprise left turn lane 1, direct lane 2, left-hand rotation stop line 6, isolation strip 3 and left-hand rotation district 4, described left-hand rotation district 4 is provided with the first earth magnetism detector 7 with left-hand rotation stop line 6 junction, stage casing, described left-hand rotation district 4 is provided with the second earth magnetism detector 8, described first earth magnetism detector 7 and the second earth magnetism detector 8 are strip, described first earth magnetism vehicle sensors 7 is parallel with left-hand rotation stop line 6, described second earth magnetism vehicle sensors 8 and driving stop line 6 are in miter angle, described isolation strip 3 is provided with wireless launcher 9, wireless launcher 9 is electrically connected with the first earth magnetism detector 7 and the second earth magnetism detector 8, the described left turn lane 1 diagonal angle in opposite directions right corner in track is provided with a red text LED notice board 10, described notice board 10 and wireless launcher 9 wireless connections, LED notice board 10 and left-hand rotation stop line 6 are in miter angle, between left turn lane 1, direct lane 2 is lane line 5.
The above, be only detailed description of the invention of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
