In this paper,by analyzing the freeway macroscopic dynamic traffic flow model,Back Propagation(BP) neural network model is presented aiming at nonlinear and time-variant system of freeway traffic flow.
The superhighway video frequency surveillance system divides many classes management structure to carry on the management, the entry-level toll station imitates the video frequency picture to make use of the WDM or technique of FDMs, delivering 32 roads,64 roads or more video frequency signals of roadses on the single fiber optic of 芯 , carrying out the toll station video frequency surveillance picture concentration up spread the function that the superior manages the organization;
In order to monitor and control the situations of traffic, car inspectors in shape of circular line microwave car inspectors atmosphere inspectors and sight inspectors large-scale changeable information and small-scale changeable information sign and remote cameras are installed along with the superhighway.
As an information superhighway between the surface membrane and the nucleus, Ras-MAPK cascades, through activating their specific nuclear transcription factor targets, are actively involved in the regulation of gene expression.
Once set up on the standard reference materials, the analytical procedure was transferred and applied to laurel leaves sampled in proximity to a superhighway and in the Po river mouth area.
The US Vice President, Al Gore, in a speech on the information superhighway, suggested that it could be used to remotely control a nuclear reactor.
Special attention is paid to the role of phloem and xylem as a superhighway, rapidly transmitting signals as well as products of stress gene expression: RNAs, proteins, transcription factors.
In this paper, we explore some characteristics of the Information Superhighway and the World Wide Web metaphors in the light of the current developments in information technology.
