Sensors play a role in Lhasa traffic intelligent command system

Abstract: Sensors play a role in Lhasa traffic intelligent command system Information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. We got the news from the special working conference on road traffic safety management this winter and next spring of the traffic control department of Lhasa City. Lhasa City plans to invest 30 million yuan to gradually establish an intelligent traffic command system in Lhasa City, including the establishment of an intelligent traffic command center, in Lhasa urban area and . More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article about the role of sensors in the Lhasa traffic intelligent command system. We got the news from the special working conference on road traffic safety management this winter and next spring of the traffic control department of Lhasa City. Lhasa City plans to invest 30 million yuan to gradually establish an intelligent traffic command system in Lhasa City, including the establishment of an intelligent traffic command center, in Lhasa urban area and More than 150 installations on main road sections in various counties“electronic*”, which mainly monitors traffic violations such as running red lights and speeding. This work will be completed and put into use as soon as June this year. On January 10, Yu Xuwen, deputy director of the Lhasa Municipal Bureau of Public Health, introduced the general functions of the Lhasa traffic intelligent command system to reporters. The intelligent operation adjusted the traffic lights according to the traffic flow. The time was less than 50 meters, and the car stopped 6 times. It took 25 minutes to drive from the western suburbs to the eastern suburbs. Yang Yue, an office worker, said that in addition to the renovation of Zhonghe International City, the reconstruction of the East Road and the Potala Palace In addition to the fact that the construction of the underground passage in the square is completely closed, there are many detouring vehicles. The main reason is that the number of vehicles in Lhasa has increased too fast in the past two years. According to the latest statistics, the number of motor vehicles in the region has approached 200,000, and 220,000 people have motor vehicle driving licenses. Among them, the rapid growth of private cars in Lhasa has become a major feature. As of December 31, 2009, the number of motor vehicles registered in Lhasa has reached 94,200, 70% of which are private cars. Yang Yue said:“At some intersections in Lhasa, there is not much traffic flow, but the red light time is very long. At the intersection with heavy traffic flow, the green light has ended, and the vehicles have not finished.”The intelligent traffic command center to be established in Lhasa soon will solve such contradictions. According to reports, the Lhasa Municipal Bureau has learned valuable experience from Beijing and Nanjing, where domestic traffic intelligence operations are mature. The intelligent traffic command center implements scientific operation, thereby narrowing the gap with inland cities in traffic management. It mainly monitors the major traffic arteries in Lhasa city through the control room, and adjusts the flashing time of traffic lights in real time according to the traffic flow during the rush hour and the rush hour, so as to improve the operation efficiency, make the traffic smoother and travel easier. For example, when the traffic flow in the east-west direction of Wucha Road is very heavy, the command center can appropriately extend the green light time to allow waiting vehicles to pass smoothly. Speed ​​limit cards will be disabled“electronic*”The intelligent system covering important roads with a planned investment of 30 million yuan also includes more than 150 installations at major intersections and traffic arteries in Lhasa urban areas, important intersections where the counties and counties of Lhasa are located, and important sections of National Highway 318 and National Highway 109 within the jurisdiction of Lhasa. where“electronic*”, to automatically capture traffic violations such as speeding and running red lights. The intelligent traffic command system will also realize the interconnection of seven counties, and monitor the traffic conditions of each main road section in real time, which will play a very important role in cracking down on traffic violations such as hit-and-run, speeding, and overloading. With the gradual implementation of the intelligent work of the traffic command system,“electronic*”Will also replace * some human functions, the biggest change is“speed limit card”system will follow“electronic*”After the network coverage is completed, exit the stage of history. In 2007,“7·13”After the serious traffic accident, the Lhasa traffic control department decided to implement the“speed limit card”According to the system, more than 10 traffic checkpoints are set up on National Highway 318 and National Highway 109. Every motor vehicle entering or leaving Lhasa must receive a speed limit card marked with a clear time, and fill in the time at each checkpoint. Speeding fines. Over the past three years, this measure has been extended to most parts of the region because of its obvious effect. However, the disadvantages of manual operation are not without. For example, the driver can wait for the specified time when parking, some drivers do not hand in the card as required, the efficiency is too low, and a lot of manpower is wasted.“electronic*”'s auto-snap function will solve this problem. Electronic eyes, also known as electronic eyes, are generally installed at traffic light intersections to monitor vehicle violations. The electronic eye uses the induction line to sense the pressure from the car on the road, collects the signal to the central processing unit through the sensor, and sends it to the register for temporary storage. In the same time interval (in the red light cycle), if two pulse signals are generated at the same time, it is regarded as“efficient”. To put it simply, if the red light is on at that time, your front wheels have passed the line, and the rear wheels have also passed the line, then two pulses are generated, and the electronic eye will take a picture. After the image is downloaded and transmitted to the command center, the image needs to be registered, numbered, announced, and then transmitted to the central computer database. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
