基于矿区实测数据的流体力学交通流模型研究

STUDY ON A HYDRODYNAMICS MODEL BASED ON MINE AREA TRAFFIC DATA

本文针对流体力学交通流模型中的一阶连续介质理论模型给出一种改进方法———将单车道随机元胞自动机交通流模型中的随机参量引入其中,生成一组反映加速度的分段函数并且重新构建了一阶连续介质理论模型的交通流基本图。在矿区实测交通流数据的基础上,应用单车道随机元胞自动机交通流模型和改进的一阶连续介质理论模型分别进行了数值模拟和分析。

According to a hydrodynamics traffic model, the paper raises a new method to improve the first order continuum traffic model by incorporating a stochastic parameter used by a single lane stochastic traffic cellular automaton model. After deriving a segmented function, we rebuild the traffic fundamental diagram. Based on the mine area traffic data and simulations, the paper gives a comparison and discussions of both models.
