The necessity of road transportation control energy-saving lamps

With the development of economy, speed up urbanization, a sharp increase in the number of motor vehicles, which caused a problem increasingly serious traffic: traffic jam, even frequent traffic accidents, noise and air pollution is serious, the public transport system efficiency drops, etc.

with the development of economy, the speeding up of urbanization and the rapid increase of vehicle number, the traffic problem is increasingly serious, traffic congestion, even frequent traffic accidents, air and noise pollution is serious, the public transport system efficiency is declining. There are usually two ways to solve this problem. One is to build roads and Bridges, it is the most direct way to improve road traffic conditions. However, due to the limitation of urban demolition, huge investment, the implementation of difficult. Secondly, the existing road traffic conditions to implement traffic control and management, give full play to the existing road traffic capacity. A large number of facts have proved the validity of this method. The path of modern high lamp pole is the price of the complex and diverse, often several, dozens or even hundreds of intersection are interrelated. In this case, there is no an experienced police can do anything. Therefore, people pay more and more attention to the advanced science and technology is applied to traffic management, so as to promote the development of the automatic traffic control technology; The continuous development of the traffic light. The purpose of road traffic control can be defined as: in some administrative rules and regulations, under the constraint of appropriate mode of operation, to ensure that the public and private transportation has the best traffic operating conditions. For this purpose the development of road traffic control system; Traffic lights will be controlled object as a whole, USES the scientific method of traffic flow time division, maximum limit to ensure the continuity of the traffic flow movement, make reduce conflict, is accused of regional traffic flow smoothly and orderly operation.
