Traffic signal device

Abstract

The invention discloses a traffic signal device which comprises signal devices, wherein each signal device is controlled by a traffic signal control device, is arranged on one side of a road and comprises an indicator light device arranged at an intersection, the indicator light device comprises an indicator light capable of indicating vehicles to stop, go straight, turn right or turn left as well as a countdown device matched with the indicator light; each signal device further comprises a prompt signal device arranged at an interval with the indicator light device, and the prompt signal device is provided with signal lights capable of indicating the vehicles to go straight, turn right or turn left sequentially to enter a section between the indicator light device and the prompt signal device so as to wait to pass the intersection. The vehicles at the intersection can be guided to pass rapidly and orderly, the jam phenomenon of the vehicles at the intersection is avoided, and the vehicle speed at the intersection and the utilization rate of the intersection are increased.

Description

technical field [0001] The invention relates to a traffic control device for road vehicles, in particular to a traffic signal device capable of instructing vehicles to pass through road intersections smoothly. Background technique [0002] Because of the convenience of vehicle use, it has become an indispensable means of transportation and transportation for people, so there are more and more vehicles on the road, which greatly increases the difficulty of road traffic, especially the traffic at traffic intersections. . At present, the traffic at the intersection is mainly through the traffic lights installed at the intersection to indicate the vehicles to pass through the intersection, while the traffic lights are installed with red, yellow, and green signal lights through the installation frame, and the red, yellow, and green signals are periodically changed through the signal control device. But this kind of signal light has very big inconvenience: not only needs the traf...

Problems solved by technology

At present, the traffic at the intersection is mainly through the traffic lights installed at the intersection to indicate the vehicles to pass through the intersection, while the traffic lights are installed with red, yellow, and green signal lights through the installation frame, and the red, yellow, and green signals are periodically changed through the signal control device. But this kind of signal light has very big inconvenience: not only needs the traffic police auxiliary guidance sometimes, and in the red light signal time, the vehicle is parked in the waiting area of ​​the crossing, has narrowed down the scope of use of the crossing, and when the green light signal is turned on At this time, the vehicles waiting for release after the stop line cannot immediately start to pass the stop line and thus cannot quickly pass through the intersection, which prolongs the time for vehicles to pass through the traffic intersection, which reduces the effective utilization of the traffic intersection to a certain extent, thereby reducing the number of vehicles at the intersection. traffic, it is easy to cause a vicious circle, and even the intersection is blocked, which makes the vehicle consume more energy and increases the environmental pollution
