The travel time of left-turning vehicles at signalized intersection was discussed. Under the assumption that the opposing through vehicles headway follows M3 distribution, the travel time model was established on the basis of gap theory and queue theory. Comparison was done with the common model based on the assumption that the opposing through vehicles(More)

The database system design of Shared Information Platform for Freeway Transportation (SIPFT) is proposed in this paper. Information sources, components and functional requirements of the database(More)
Based on radar data and ground weather phenomenon, two kinds of severe convective weathers, hail and gale process and tornado process, are simulated by the model MM5. The simulated radar echo and actual radar echo are analyzed. Simulated micro-physics and dynamic characteristic are researched. The possible reasons of the difference with microphysical and(More)
As a blended teaching strategy, the flipped classroom model has shifted the teaching task from traditional knowledge instruction to ability enrichment. Based on the main future of it, this report illustrates advantages of the flipped classroom and gives suggestions, including establishing the instruction structure and designing every process, of the model(More)
