Total Framework and Operation Mechanism Research Based on Internet of Things of Maintaining Traffic Smooth in Bad Weather

Frequent inclement weather seriously impacts a traffic system, and maintaining smooth traffic in bad weather is an important problem to city and highway traffic. This paper is based on the "internet of things application demonstration project of maintaining road traffic unblocked in extreme meteorological conditions". The first batch project of the internet of things in Beijing proposed the basic location of maintaining road traffic unblocked in bad meteorological conditions; using the top design theory and method of traffic information system with the core of service function, analysing comprehensively the function of system service, raising the overall system architecture, analyzing three-level architecture of maintaining smooth traffic in bad weather of the city/key management departments/emergency support teams, and the mechanism of system operation, data sharing. The beneficial discussion on the total system framework and operating mechanism of maintaining traffic smooth in bad weather is valuable to the standardization, extendibility, and the sustainability of system construction.
