How to use intelligent traffic lights to build smart cities?

With the acceleration of urbanization and the continuous growth of traffic volume, traffic congestion and other problems are getting more serious. How to effectively manage urban traffic and provide citizens convenient transportation services? The construction of smart city has become one of the important ways to solve this problem. The intelligent traffic lights are an important part of intelligent transportation system. The traffic signal manufacturers will analyze the ideas of smart city construction. In order to meet the application and development of intelligent traffic lights, the existing problems now is solving.

• Firstly, smart city construction ideas. Smart city refers to an urban construction method that integrates and utilizes various resources of the city. Through information of Internet technology, it improves the intelligent, green and comfortable degree of the city. Smart city realizes the sustainable development of the city. It is scientific, systematic, feasible and sustainable, and in accordance with the development concept of “people-oriented, innovation-driven, intelligent support, open integration”, it has established an open, collaborative and shared urban management system to realize the utilization and optimal distribution of urban resources.
• Second, the application and development of intelligent traffic lights. Intelligent traffic lights are an important part of the construction of smart cities. They can  improve traffic efficiency.It also reduce traffic accident rates and alleviate urban traffic congestion. At present, many cities have begun to use intelligent traffic signal light technology, such as the traffic control center in Stockholm, Sweden. These countries can monitor traffic congestion in real time.The development trend of intelligent traffic lights also shows the characteristics of diversification, intelligence and ecology. For example, some new intelligent traffic lights use machine  network and other technologies to predict traffic flow. It can achieve more accurate control and adjustment of traffic lights. Other intelligent traffic lights also use new energy sources,such as solar energy and wind energy.
• Thirdly. Existing problems.The intelligent traffic light  has been widely used and promoted. There are still some problems in the practical application process. At present, the cost of intelligent traffic lights is still relatively high. Some new intelligent traffic lights are expensive. Intelligent traffic lights are mainly used in the field of urban public transport. The private enterprises also play a very important role in this field.

The information sharing and benefits between enterprises and the government is more difficult. Although intelligent traffic lights have brought convenience to the city, the data problem is still very serious. The intelligent traffic  lights will collect a large number of vehicles, pedestrians and other information. If the information is illegally obtained, it will be like a “digital castle”, hackers and viruses and other attacks.

The construction of smart cities is bound to be one of the trends of future development. The intelligent traffic lights are also a technology with broad development prospects in the intelligent transportation system. In the future, intelligent traffic lights will pay ,ore attentiom to data problems. Innovative capital support can make more contributions to the intelligent, standardized and humanized development of the city.
