With the emergence of a number of American made cars, American cities in the early 20th century often saw bicycles, animal powered vehicles, cars and pedestrians sharing a street and road, and traffic accidents occurred frequently. Many early traffic lights appeared one after another during this period. In 1910, Ernest Schilling of Chicago applied for the U.S. patent, which may be an automatic traffic control system, which uses unlighted "stop" and "continue" as command signals

in 1914, an electric traffic signal light - "electric signal light" appeared in Cleveland, Ohio, USA. With the development of various means of transportation and the needs of traffic command, a veritable tricolor light (red, yellow and green signs) was born in 1918. It is a tricolor round four-sided projector, which is installed on a tower on the Fifth Avenue of New York City. Due to its birth, urban traffic has been greatly improved

Wuhan Tian'an transportation facilities Co., Ltd. is a diversified company integrating the design, development and service of parking lot facilities, road transportation facilities, intelligent "all-in-one card" management system and electromechanical integrated products, stainless steel non-standard products, etc. Since its establishment, the company has actively learned from and made use of today's international new scientific and technological achievements, introduced advanced production equipment, and constantly absorbed * scientific research and design personnel with a complete set of relatively expensive prices, developed a system of high-tech products with international advanced standards, and achieved brilliant achievements in the industry. It is widely used in roads, communities, sports fields, amusement parks, parks, organs, factories, schools, hotels, hospitals and other places, and has been widely praised by the society, and the brand image has been continuously improved. In line with the development strategy of quality assurance, real price, meticulous service, people-oriented, innovation, value for money, high-quality service, integration of resources, and good alliance, the company has continuously accumulated experience, so that the strength and staff of the company have become stronger and stronger.

the meeting believed that increasing supervision, resolutely eliminating lazy politics and other inaction, and promoting competing for work and achievement are important measures to vigorously implement policies and promote development. The meeting heard the report on the verification and accountability of the inaction found in the supervision this year. On the basis of the accountability of 59 cadres in 7 provinces in the early * approval, the central and local stock funds of 10.9 billion yuan and 296.6 billion yuan were recovered and 312500 mu of idle land were disposed of by the end of August, aiming at the problems of inaction such as capital precipitation, project delay, idle land and slow shed reform, Recently, more than 20 provinces (autonomous regions and municipalities) will hold more than 200 cadres, including department and bureau level, accountable in accordance with the law and regulations. The meeting required that the problems found should be rectified promptly, and the recovered funds should be transferred to the places that take the initiative to invest in the key areas urgently needed by development and people's livelihood. Before the end of the year, the idle land that has not been disposed of in all provinces (autonomous regions and municipalities) will be recovered or deducted according to the area of the annual new construction land plan indicators. We should formulate supervision measures, promote all departments and localities to take the initiative to conduct self-examination and supervision at all levels, and publicize the problems found and the progress of rectification to the public for the supervision of the people. Gerry said, "we can then dilute it to an appropriate concentration according to the required mechanical properties, connect the mechanism with the inspection results, and use accountability tools to eliminate the" disease "of inaction, so that the" Taiping officials "of inaction can't mix.". All regions and departments should take the implementation of policies and measures as "military orders" and iron discipline, take the initiative to solve the problems of reform and development, and ensure the completion of the main goals and tasks of the year

at the same time, the signal light setting will be more humanized. Generally speaking, it is released in the order of "straight ahead first and then turn left". Now there is no fixed mode, and everything depends on the actual traffic conditions. Zhuzhengjiang, a policeman from the order Department of the traffic police brigade, told that the construction of the intelligent transportation transformation project has made the original complex and messy systems centralized and unified. All the signal systems, monitoring systems, and investigation and control systems in the county are included in the "integrated platform" of an electric 94 chlorinated polyethylene rubber blend waterproof coiled material brain. As long as you log in to their respective accounts, you can find relevant information in * time, It greatly improves the efficiency of tracking suspected vehicles. Through the monitoring of each intersection, suspected vehicles can be found in time, and then the license plate number is set in advance in the system. The system will give an alarm every time the vehicle reaches an intersection. The police can intercept suspected vehicles in time by extending the signal time in the signal control system. Zhu Zhengjiang said that the second phase project will include all the remaining 90 intersections in the monitoring, so that the road conditions of the whole county can be clear, which will further alleviate the current situation of traffic congestion in the whole county

Lao Ran's "thirty years of urban traffic control in China" comprehensively summarizes the development of road traffic signal control system in the previous three decades. In the 20 years from 1978 to the end of the 19th century, the research on road traffic signal control system was in the initial exploration stage. Relying on the national key research projects of "the Seventh Five Year Plan" and "the Eighth Five Year Plan", after ten years of technical research, the traffic management science Research Institute of the Ministry of public security Tongji University and Nanjing Institute 28 of the Ministry of mechanical and electrical engineering at that time jointly developed * road traffic signal control systems with independent intellectual property rights in China. During this period, the construction of road traffic signal control systems was mainly concentrated in large cities, focusing on the introduction of foreign systems, focusing on the digestion and absorption of foreign related technologies. In the ten years after 2000, with the implementation of the "unblocked project" and the construction of local urban traffic command centers, the road traffic signal control system has entered the stage of application and development. Domestic manufacturers have developed a series of road traffic signal control systems and began to apply them on a large scale throughout the country, and the relevant standards have been gradually released and implemented

according to the optical principle, the wavelength of red light is very long, the ability to penetrate the air is strong, and it is more noticeable than other signals. Therefore, as a signal of no passage, green is used as a notification signal because of the difference between red and green *, which is easy to distinguish (red and green blind are actually a few). In addition, color can also express some specific meanings. To express heat or intensity, * strong is red, followed by yellow. Green means colder and calmer. Therefore, people often use red to represent danger, yellow to represent warning, and green to represent safety. Development status of Qiaokou solar LED street lamp manufacturer industry
