Traffic light for highway

Abstract

The invention discloses a traffic light for a highway, and belongs to the field of a street lamp. The traffic light for the highway comprises a lamp post; a ventilating duct is formed in the axial direction of the lamp post; an air inlet corresponding to the ventilating duct is formed in the lamp post; a clamping block is fixedly connected to the inner side wall of the ventilating duct; a floatingplate is in contact connection with the clamping block; an air outlet is formed in the lamp post, and the air outlet is positioned above the floating plate; a hollow rod is fixedly connected to the floating plate; the outer side wall of the hollow rod is fixedly connected with a plurality of warning lamps arranged at equal intervals; light-transmitting glass for watching the warning lamps is arranged on the lamp post; and a coil turn is sleeved in the hollow rod. Airflow generated when an automobile runs at a high speed can be utilized, the warning lamp flickers due to the fact that the induction current is far away, and the flickering warning lamp has a stronger warning effect on rear vehicles; and meanwhile, the vehicle following distance can be judged according to the flickering distance of the warning lamp, so that a response is made in advance, the probability of accidents is reduced, and the overall driving safety is improved.

Description

technical field [0001] The invention relates to the field of street lamps, and more specifically, relates to a traffic lamp for expressways. Background technique [0002] Expressway, referred to as expressway, refers to a highway designed for high-speed driving of automobiles. According to China's "Technical Standards for Highway Engineering", expressways are multi-lane highways designed for automobiles to travel in separate directions and in separate lanes, and all access and exit are controlled. The annual average daily design traffic volume of the expressway should be more than 15,000 passenger cars, and the design speed should be 80 to 120 kilometers per hour. [0003] The existing highways in our country are open all day long, and drivers often drive at night. Due to the high speed on the highway, the driving time is long, and the vision at night is obstructed, drivers will experience inattention and fatigue. As a result, in the process of driving, the driver unconscio...

Problems solved by technology

[0003] The existing highways in our country are open all day long, and drivers often drive at night. Due to the high speed on the highway, the driving time is long, and the vision at night is obstructed, drivers will experience inattention and fatigue. As a result, in the process of driving, the driver unconsciously follows the car at a very close distance, and it is difficult to detect it, resulting in a rear-end collision accident. In the prior art, it is difficult for the driver to find the following car between the vehicle and the vehicle through the external reference when driving at night. The distance cannot be quickly reminded, which will increase the probability of accidents. At the same time, the airflow generated by the vehicle at high speed is not fully utilized.
