The Design of the Traffic Light Control System Based on Internet of Things

Abstract The Internet of things is in communication networks such as the Internet and mobile communication network based according to different application area needs using has perception, communication and computing power of smart objects automatically obtain various kinds of  information of the physical world, will all be able to inpidually addressable physical object interconnection, to achieve the overall perception "reliable transmission" intelligent processing, construction of people and things, things and things connected to the intelligent information service system。 Based on IOT intelligent traffic signal lamp control， through wireless communication， infrared sensor， positioning， laser scanning and radio frequency identification information technology were vehicle flow detection, vehicle monitoring species, pedestrian detection, roads, environmental monitoring, human, vehicle, road and traffic control is connected to the network, through real-time optimization time signal to control the traffic lights transform, namely the control in each lane of motor vehicles and pedestrians in the passage of time, improve the intersection capacity。

Firstly from intelligent transportation system (ITS) and Internet of things related to the contents of the domestic and foreign research development status of proposed the problems and shortcomings existing in the existing intelligent transportation system model and to explore the significance of the model of intelligent transportation systems and architecture research networking environment; secondly，through the analysis of the existing problems, expounds the intelligent , transportation system (ITS) necessity of introducing the technology of Internet of things; and focuses on based on radio frequency identification (RFID) technology and embedded technology。
