The ＂new version of traffic lights＂ detonated the hot search, and the response came!
eightOn February 22nd, the news about the "new national standard" traffic lights went on a hot search. The news said that it was necessary to unify the style of traffic lights nationwide and cancel the countdown design of traffic lights.This has attracted many car owners to vomit. In the eyes of car owners, in addition to the numerous and difficult-to-remember traffic light rules in the new national standard, red lights and green lights will also light up at the same time, which makes them a little overwhelmed.
So, is this news true? After investigation by Yangzi Evening News/Zi Niu News reporter,The so-called "new national standard" and "Code for Setting and Installation of Road Traffic Lights" were released in 2016 and implemented as early as 2017.
On the evening of 22nd, the Traffic Management Bureau of @ Ministry of Public Security released Weibo’s statement:Recently, the online biography "the new national standard for traffic lights will be implemented in 2022" has aroused public concern. In this regard, the drafting unit, the Traffic Management Science Research Institute of the Ministry of Public Security, attached great importance to it and explained the relevant situation.
Not only that, as early as November 2018, after preliminary research and equipment testing in Nanjing,The intersection of Huaihai Road on Zhongshan South Road and Xikang Road on Beijing West Road took the lead in piloting the new beacon.The reporter also learned that the "new national standard" at that time was not widely promoted, but the straight arrow light was gradually changed into a disc signal light to make drivers feel deeply. In fact, on the basis of the national standard, Nanjing traffic police adapted to local conditions, and through research and big data analysis, optimized and upgraded the setting and timing of traffic lights, and launched a more convenient design for the people.
Cancel the countdown to the traffic lights? Nanjing will not cancel
In addition, regarding the issue of "canceling the countdown to traffic lights", the reporter found that there is no relationship between the countdown and the national standard of traffic lights, which is based on the public security industry standard "GA/T 508-2014" Road Traffic Signal Countdown Display ". This industry standard is neither national standard nor mandatory, so all localities can choose to install it according to the actual situation.As far as Nanjing is concerned, the countdown to traffic lights will not be cancelled.
How did you change it? The arrow light is changed into a circular signal light.
In fact, for a long time, most of the traffic lights at Nanjing intersection use arrow lights. That is to say,How to get to the intersection, just look at the arrow, and vehicles in which direction can pass when the green light is on.At that time, after the implementation of the new national standard, there were corresponding requirements for setting traffic lights at different intersections. Because most intersections in Nanjing can’t meet the requirements of the new national standard, it is required to change the straight traffic lights from arrow lights to disc lights to guide the traffic. Since then, Nanjing traffic control department has gradually changed the straight arrow lights at intersections into circular signal lights, which I believe the majority of drivers are deeply impressed by.
Then, the straight direction indicator light at the intersection is changed to a disc light. How should the vehicle go? The circular lamp is a motor vehicle signal lamp, while the arrow lamp is a direction indicator lamp. According to the national standard, motor vehicle signal lights and direction indicator lights are not allowed to light green at the same time, which is also the reason why some drivers can’t understand the signal lights. For example, if the circular light is green and the left and right turn signals are off, it means that the intersection can go straight, turn left and turn right at the same time. When the circular light is red and the left and right turn signals are not on, the left turn is forbidden, while the right turn is allowed. If the arrow red light appears on the right turn signal at this time, it means that all three directions are forbidden to pass.
In fact, it is not difficult to understand the national standard version of traffic lights. First, remember the traffic rules of circular lights, namelyThe green light is on, and all three directions can pass; The red light is on, and you can turn right for 24 hours.On this basis, due to the different traffic flow at each intersection, the traffic control department will limit or guide the turning traffic flow by adding direction indicator lights. For example, the disc light is red, and when the left turn is green, it means that both left and right turn vehicles can pass; Turn left with a green light and turn right with a red light, which means that only vehicles turning left can pass at this time.
What is the current situation in Nanjing? Not widely promoted, optimized and upgraded according to actual needs.
At present, in addition to the national standard used in the previous two intersections, there are also some intersections in Nanjing that use national standard signal lights. However, it has not been widely promoted in the city. In fact, in order to make it more convenient for citizens to pass, Nanjing traffic police not only upgraded the files on the basis of national standards, but also optimized and upgraded the traffic lights according to actual needs.
The reporter learned that the Signal Timing Center of Nanjing Traffic Management Bureau has managed more than 1,600 signalized intersections in the main urban area of Nanjing as a whole, and divided the intersections into four categories according to the road grade and traffic flow, and finely adjusted the grades. At present, more than 800 intersection traffic lights in the city are jointly controlled by network, and the traffic control department can adjust the intersection traffic lights in real time through remote background according to actual needs.
The signal timing scheme of main roads, business districts and key intersections in scenic spots directly affects the overall efficiency of the city’s roads, and the signal timing scheme should adapt to the traffic changes in different periods to better ensure the road traffic efficiency. To this end, the Nanjing Traffic Management Bureau collects a variety of road conditions and traffic flow big data from multiple platforms such as the network car platform and the navigation map platform, and rationally configures the traffic signal scheme. At key intersections, the original 3-4 sets of timing schemes have been increased to 7 sets of timing schemes, and at general intersections and basic intersections, no less than 5 sets of timing schemes have been set up, which have been optimized from multiple angles and levels.
The Nanjing Traffic Management Department also conducted a comprehensive investigation on the operation of the existing green wave belt, and subdivided the green wave belt into two-way green waves in small sections, segmented green waves on main roads, safe green waves at night and green waves during holidays according to the characteristics of time periods and road sections, forming a green wave network.
It is understood that the Nanjing signal light optimization project has changed from "car-oriented" to "people-oriented" in the past. In order to improve the pedestrian crossing experience, Nanjing Traffic Management Department innovatively introduced the inductive pedestrian signal lamp, which senses the pedestrians who are about to cross the crosswalk through two sets of detection equipment, and intelligently releases the signal lamp, fully ensuring the safety of pedestrians, taking into account the right of way of motor vehicles, and maximizing the traffic efficiency at intersections.
