The Intelligent Transportation System (ITS) targets to a coordinated traffic system by applying the advanced wireless communication technologies for road traffic scheduling. Towards an accurate road traffic control, the short-term traffic forecasting which predicts the road traffic at the particular site in a short period is often useful and important. In existing works, Seasonal Autoregressive Integrated...
Even the greedy routing is widely used in wireless networks, its theoretical study is still limited in vehicle environments. In this paper, we theoretically analyze the performance of the greedy routing under three typical vehicle scenarios, i.e., the single-lane road, the multilane road, and the multilevel road. We first propose the analytical model by analyzing characteristics of traffic environments,...
The distributed hydrological model, SWAT, was used to study the seasonal and interannual variation of the runoff in upstream Dagu River watershed and the governing processes as well. The model output is sensitive to five parameters (e.g., Cn2, Esco, and Sol_Awc). The modeled result shows maximum monthly runoff occurring in August and minimum in February, consistent with the observation. The average...
This paper establishes the test models of individual effect and joint effect of the futures price volatility determinants on the basis of GARCH(1,1) model, and takes example for Wheat futures, and analyses empirically the relationship of futures price volatility and time to maturity, of futures price volatility and the day of week, of futures price volatility and volume and open interest. the study...
