中文摘要：
在周期性边界条件下，通过引入预测车辆间距对Noise-First模型进行改进，数值模拟了不同参数下的交通情形．研究表明：引入预测间距的Noise—First模型更能真实地反映实际交通状况，不仅再现了启止波、同步流，而且出现了亚稳态，非平衡相变等与实际道路交通一致的非线性现象．
英文摘要：
In this context, we introduce anticipation headway to modify the Noise-First NaSch model under condition of periodic boundary. The traffic situation with different parameters can be numerical simulated. It was indicated that the Noise-First model with added anticipation headway is more realistic in reflecting traffic flow. Not only start-stop wave and synchronized flow but also the metastable state can be obtained by numerical simulation. The modified model can reproduce nonlinear phenomena which tallies with the real traffic.
