With the development of advanced technologies such as computer technology，network technology and sensor technology，based on the internet.
The expansion and extension of the foundation formed a new generation of network technology that the Internet of things (for short as IOT)
The Internet of Things is a major development opportunity facing mankind in the 21st century. The Internet of Things will be widely used is the second computer，the Internet and mobile communications network after another revolution in information. At present，many countries in the world cities are plagued by the increasingly prominent road congestion and safety problems，and road traffic utilization is prevalent not high，inefficient network operation，limited transport modernization. The root cause of these problems one of the reasons is that traffic information is not symmetrical，traffic information service function is not perfect，and traffic information management is not in place. At the same time，IoT technology will help solve these traffic problems，and then the entire social package including the transport industry has a huge and far-reaching impact. As a new technology generation and development，in-depth research The characteristics of traffic information collection，transmission，processing and service under the Internet of Things on Traffic Information Network "to conduct a systematic study of the actual needs of the development of the transport industry information will be conducive to improve the efficiency of the transportation system and promote the readjustment of the industrial structure and upgrading of the transport industry.
The paper deeply studies the impact of IOT technology on traffic and determines the research of regional traffic information network.
Based on this，the hierarchical structure and system of regional traffic information network based on Internet of Things.
Internet of Things (IoT) links the objects of the real world to the virtual world，and enables anytime，anywhere connectivity for anything that has an ON and OFF switch. It constitutes to a world where physical objects and living beings，as well as virtual data and environments，interact with each other. Large amount of data is generated as large numbers of devices are connected to the internet. So this large amount of data has to be controlled and converted to useful information in order to develop efficient systems. In this paper，we focus on to Traffic Information network based on IoT system that is used to build intelligent transportation system (ITS).Method to choose an IoT based in intelligent transportation systems are given to support the Smart City vision，which aims at employingthe advanced and powerful communication technologies for the administration of the city.
