| Abstract: | This paper presents the design of a highway information system based on Wireless Broadband Metropolitan Area Networks (WMAN), which collects the video of road transportation flow by a digital network camera and makes use of the medium processor to carry on preprocessing, and thus gets the vehicle flow, speed calculation, vehicle classification and etc. The video and highway information are transmitted to the remote information process center through WMAN. It is shown that the system can attain medium or high speed of real-time video transmission, have the advantage of safety, save the funds and be expanded etc. |
