Say goodbye to the red light 120 seconds, the green light for 30 seconds! Is it more convenient or faster to deduct points for new traffic lights?

Many car owners have two major problems when crossing traffic lights: one is to give way to pedestrians, and the other is to wait for the green light to pass.

Finally, I waited for a green light, and as a result, pedestrians had to wait for another round. Many car owners also reported that the traffic lights on some main roads were set unreasonably, waiting for 120 seconds and passing for 30 seconds, which seriously blocked roads, especially in the middle of the night, but it was very inconvenient to wait for such a long time to pass.

Traffic lights are important guides at intersections and play an important role in maintaining good traffic order. So is there a setting that can automatically sense the traffic flow and people flow and automatically reduce the waiting time for the red light?

The traffic lights we often see in our daily life are all controlled at regular intervals, that is, the switching time of red light, yellow light and green light is set, and the countdown or strobe is set at the same time, which is convenient for the owner to prepare for driving or parking.

Recently, the traffic lights at some intersections in Beijing, Shanghai, Jiangsu, Shandong, Guangdong and other regions did not have the countdown function, but directly switched to other colors, which also made many drivers mistakenly think that the traffic lights were out of order. It turns out that this is a new version of intelligent traffic light, and the traffic police department has given it a new name: "Intelligent Traffic Signal Controller".

The wide application of "intelligent traffic signal controller" has attracted everyone's attention, so what is this kind of intelligent traffic light?

"Intelligent traffic signal controller" is a release method that can adjust traffic lights according to traffic flow.

The working principle of intelligent traffic light induction detector is to analyze the traffic conditions in different directions in real time by detecting vehicles on the road, and automatically adjust the traffic light signal duration in different directions through adaptive algorithm to intelligently relieve traffic pressure.

At the intersection with traffic lights, if the traffic in the east-west direction is dense and the vehicles in the north-south direction are sparse, this intelligent traffic light will automatically increase the green light time in the east-west direction and compress the red light time in the north-south direction, thus automatically controlling the vehicle release time in different directions and reducing the green light release. Of course, guidance control also has its applicable conditions, that is, the optimization effect is obvious at intersections with unsaturated and large traffic flow changes.

The difference between old and new traffic lights

Traditional traffic lights: Because the duration of traffic lights in all directions is fixed, if there are no pedestrians and traffic in one direction, it will always be a green light, which will inevitably waste the waiting time of vehicles in the other direction, thus reducing the traffic efficiency of the road.

New intelligent traffic lights: according to the change of traffic volume in different time periods, the replacement cycle of traffic lights is automatically adjusted, so that vehicles at intersections are no longer stupid and miserable. At many busy intersections, the daily traffic volume is not fixed, especially in the morning and evening rush hours, and the traffic volume in several directions of the road is asymmetric. Then, during off-peak hours, intelligent traffic lights can reduce the waiting time of car owners and drive to their destinations faster.

Views of all parties on new intelligent traffic lights

This new type of intelligent inductive traffic light cancels the countdown function, which will bring some inconvenience to car owners who are used to watching seconds to determine the time of traffic lights. Many car owners even think that canceling the countdown is not very beneficial.

Supporters believe that

It is very convenient to automatically sense the traffic flow and reduce the waiting time of traffic lights. 120 seconds no longer need to use a red light, 30 seconds to pass. Especially at night, there are several red lights along the way, and the waiting time is quite long. With intelligent traffic lights, you can save a lot of time.

Opponents believe that,

Car owners must always pay attention to the switching of traffic lights. Sometimes, if they don't pay attention to when it turns red or green, it is easy to violate the rules and even cause traffic accidents.

Neutrals believe that

Intersections with large traffic gaps can be implemented, but they are not applicable in urban areas with large traffic even if they are not in peak hours. I hope the relevant departments can comprehensively consider the actual situation.

Objection. Cancel the countdown to the traffic lights.

1, the countdown was cancelled at the traffic light, and the owner didn't know how long it would take, so he couldn't get ready for driving in advance, and he couldn't respond at the first time when the green light was on, which reduced the traffic efficiency.

2. After the countdown is cancelled, car owners will really be more cautious when driving, and they will slow down before the intersection and stop in advance, which may lead to more traffic congestion.

3, no seconds, when others have passed, it is still a green light. When it comes to myself, it suddenly becomes red. I often have to brake suddenly and feel bad about my car.

4. The current intelligent control mode still brings some convenience to car owners. If intelligent control and countdown mode are combined, will the effect be better?

In order to better guide traffic order and improve traffic efficiency, there are several ways besides new intelligent traffic lights.

"Extra version" traffic light

On the basis of the original signal lamp, the "additional version" traffic light is equipped with an eye-catching light strip, which will change with the change of the signal lamp. Its luminous angle is large and its visual range is wide, which reduces the probability that the signal lamp is blocked.

With this Plus version of the traffic light, the owner no longer has to worry about the big truck or bus in front blocking the front line of sight and accidentally running a red light.

"Ground" traffic lights

Ground traffic lights? You are not mistaken, that is, the traffic lights are installed on the ground, at the north entrance of Banzhangshan Tunnel in Zhuhai. Cars passing by this location should pay more attention!

During the rush hour, this traffic light flashes yellow to remind drivers to pass carefully.

During rush hours, the traffic lights on the ground will turn red, yellow and green. When the ground is red, the vehicle stops; When the green light is on, the vehicle moves forward.

Usually, we are used to looking up at the traffic lights. This traffic light on the ground is often not so easy to attract attention, and it will be deducted if you are not careful, and only the vehicles in front of the lane can see it, so the vehicles in the rear need to pay close attention to the vehicles in front and step on the brakes in time.

In order to facilitate the majority of car owners to pay attention to this new type of traffic lights, signs and ground signs are set up in advance to remind car owners to observe the traffic situation ahead and drive correctly.

Wisdom luminous zebra crossing

In addition to traffic lights, zebra crossings are also intelligent. When the crosswalk signal light turns red, the "luminous floor tile" at the stop line on the zebra crossing will turn red with the intersection signal light, and when the signal light turns yellow or green, the "luminous floor tile" will also change synchronously.

"Luminous floor tile" not only has good high and low temperature resistance and ultraviolet resistance, but also has anti-glare function, which makes the driver's sight unaffected, greatly improves the visibility of zebra crossing at night and leaves more sufficient reaction time for the driver. Due to the unique structural design of the base, it can bear up to 200 tons of pressure.

With the help of "color prompt" and "visual impact", "intelligent luminous zebra crossing" plays a good role in prompting, effectively reducing the probability of illegal activities such as running red lights. Some areas also cooperate with voice broadcast reminders to strengthen traffic order guidance.

At present, the "intelligent luminous zebra crossing" has been used at many road intersections in Wuxi, Suzhou and Nantong, Jiangsu, and some intersections in Shenyang, Liaoning, Tangshan, Hebei, Zhengzhou, Henan and Foshan, Guangdong have also been opened for use. If the pilot effect is good, efforts will be made to install it at intersections with dense crowds and heavy traffic.
