Abstract
The invention discloses a control lamp for a tailgating left turn signal lamp. The control device comprises a left turn lane, a through-traffic lane, an isolation belt and a left turn zone, wherein a first geomagnetic vehicle sensor is arranged at the connected part of the left turn zone and the left turn lane; a second geomagnetic vehicle sensor is arranged at the middle section of the left turn zone; a wireless transmitter is arranged on the isolation belt and is electrically connected with the first geomagnetic vehicle sensor and the second geomagnetic vehicle sensor; a signal lamp bracket is arranged at a crossing opposite to the left turn lane and the through-traffic lane; a control box and signal lamps are arranged on the signal lamp bracket; the signal lamps comprise a left turn signal lamp and a through-traffic signal lamp; the control box is connected with the wireless transmitter in a wireless manner; the control box is used for respectively controlling the left turn signal lamp and the right turn signal lamp through a relay.
Description
Technical field
The present invention relates to urban road junction field of traffic control, especially relate to a kind of piggybacking left rotaring signal lamp control device improving driving efficiency.
Background technology
Crossing is as the key node in urban traffic network, and its smoothness, security 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 crossing, and crossing often becomes the key point whether urban transportation passes unimpeded.Crossing 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 crossing, 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, there is the problem that traffic efficiency is low in existing left turn lane Signalized control device.
Summary of the invention
In order to overcome above-mentioned technical matters, the invention provides a kind of piggybacking left rotaring signal lamp control device improving driving efficiency, the technical scheme of employing is as follows:
Piggybacking left rotaring signal lamp control device, comprise left turn lane, Through Lane, isolation strip and left-hand rotation district, described left-hand rotation district and left turn lane 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 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 and crossing place, Through Lane opposite are provided with signal lamp bracket, signal lamp bracket is provided with control box and signal lamp, signal lamp is divided into left rotaring signal lamp and craspedodrome signal lamp, described control box and wireless launcher wireless connections, control box is respectively by Control left rotaring signal lamp and craspedodrome signal lamp.
Further, described first earth magnetism detector and the second earth magnetism detector are strip, and length is equal with left turn lane width.
Further, described left rotaring signal lamp is LED formula text importing formula signal lamp, and described craspedodrome signal lamp is coston light.
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 of piggybacking left rotaring signal lamp control device.
