Urban real-time road condition interactive system, device and method based on internet of things

The invention provides an urban real-time road condition interactive system, a device and a method based on an internet of things. The method is that an urban traffic command center releases real-time road conduction information; after an urban real-time road condition interactive device installed in a vehicle receives the real-time road condition information, the urban real-time road condition interactive device obtains vehicle position information and current vehicle running speed information, displays the real-time road condition information and the vehicle position information to personnel on the vehicle, and transmits the vehicle position information and the current vehicle running speed information to the urban traffic command center; and urban traffic command center determines the road condition of each road section according to the received vehicle position information and the received current vehicle running speed information, and generates real-time road condition information to be released at the next time. By adopting the scheme, the real road condition information of each road section can be obtained in time and thereby drivers can conveniently and properly select running lines.
