  1. Focusing on the effects of decreasing toll on traffic flow and system cost, this paper deals with the cost evolution models by dynamically analyzing the cost and demand

    在對成本和需求進行動態分析的基礎上,建立了系統交成本的演化方程組,推導出需求對交的約束條件。
  2. We also analyze the influence of the boundary condition 、 safety distance and deceleration probability to the traffic flow. finally, we propose an crossroad modle. this model is made up of one main road and one branches : traffic with lights placed on the crossing, vehicles " breaking while running and turning to other direction while jamming. we investigate the velocity and flow of the model when the initial density, the brake and turning probabilities, the green to signal ratio are changed. then the reasons causing all the kinds of phenomena are analyzed

    最後研究了周期性界條件下的十字路口的ca模型,該模型由一條主幹道和一條支道組成,在幹道與支道的交叉路口設置紅綠燈,車輛在運行中對突發事件發生反應的剎車,路口的車輛可以轉向等各種實行為,並過計算機模擬,研究模型在改變車輛的初始密、剎車概率、轉向概率、紅綠燈信號的綠信比等各種情況下支、主幹道車輛的量的變化,並分析在各種情況下交狀況的成因,提出改善交的有效措施。
  3. Refined grids were utilized in a large - eddy simulation model for obtaining high - resolution planetary boundary data and analyzing surface layer turbulence. simulation results showed that refined meshes reduced turbulent contributions of subgrid scales, sensitivity of simulation results to sgs parameters decreased, and features of the whole boundary layer were explicitly resolved better. results also revealed flux - profile relationship correctly in surface layer and a good agreement of turbulent velocity characters with observation. therefore, it concluded that the les method was able for simulation of surface layer flow and turbulence, and might be used for further applications

    採用加密網格的大渦模式獲取界層風溫場的高解析模擬結果,並據以分析近地面層大氣的湍特性。結果表明,較小的網格尺使次網格湍貢獻率大為降低,模式計算結果對次網格參數的依賴性減小,界層整體特徵得到更好的反映。同時,模擬出的近地面層量廓線關系及湍特徵與實觀測結果吻合甚好,表明模式具有反映近地面層平均運動和湍特性的能力。
