Description
Technical field
The utility model relates to urban road junction field of traffic control, especially relate to a kind of can limit left turning vehicle cross line piggybacking turn left isolation railing.
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 also exists left turning vehicle and crosses line, affect the problem of traffic safety.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provide a kind of can limit left turning vehicle cross line piggybacking turn left isolation railing, the technical scheme of employing is as follows:
Piggybacking turns left to isolate railing, comprise isolation railing, track, supply unit, protective device and control device, described isolation railing comprises power roller, power roller is established in orbit, track is located in the groove inside road separator, described isolation railing is also provided with signal lamp, described supply unit comprises the electric stake be arranged on road separator, electricity stake is connected with the motor on isolation railing by wire, described motor is connected with power roller, described wire is wrapped on the take-up pulley on isolation railing, described control device comprises the touching switch be located on isolation railing and the trigger point being located at road separator inboard groove, described protective device is the elastic device being located at road separator inboard groove end.
Further, described signal lamp comprises red eye and greensignal light.
Further, described trigger point comprises trigger point, top and terminal trigger point.
Further, described elastic device is spring or rubber pad.
Further, the length that described track extends road separator is greater than the length of isolation railing.
Adopt above-mentioned piggybacking to turn left to isolate railing, effectively can ensure that left turning vehicle can not cross center line of road, ensure that the safety of opposite traveling vehicle.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that piggybacking turns left to isolate railing.
Detailed description of the invention
Piggybacking turns left to isolate railing as shown in Figure 1, Reference numeral 1 and 2 is respectively left turn lane and direct lane, piggybacking turns left to isolate railing and comprises isolation railing 5, track 7, supply unit, protective device and control device, described isolation railing 5 comprises power roller 8, power roller 8 is located on track 7, track 7 is located in the groove 4 inside road separator 7, the length that track 7 extends road separator 7 is greater than the length of isolating railing 5, described isolation railing 5 is also provided with red eye 13 and greensignal light 14, described supply unit comprises the electric stake 6 be arranged on road separator, electricity stake 6 is connected with the motor on isolation railing 5 by wire 12, described motor is connected with power roller 8, described wire 12 is wrapped on the take-up pulley 15 on isolation railing, described control device comprises the touching switch 9 be located on isolation railing 5 and trigger point, top 11 and the terminal trigger point 10 of being located at road separator inboard groove 4, above-mentioned trigger point can be touched with the touching switch 9 on isolation railing 5, described protective device is be located at the elastic device 16 that the spring of road separator inboard groove end or rubber pad make.
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.
