| 摘要: |
| 引入局域密度几率分布分析3种不同交通相之间的转化,运用序参量研究平均车流量的2个临界点的相变行为来计算机仿真交通流模型——优先随机慢化模型(Noise-First)。数值模拟结果与实际测得的相变结论较吻合。该模型能够真实反映交通状况。 |

| Abstract: |
| The local density distribution of probability is introduced to analyze the transfers between three kinds of traffic phases.The phase transition behavior of two critical points for the average car flow is studied with order parameter, and is simulated traffic flow model——(Noise-First Model) by computer.The numerical simulation results are more consistent with the actual measured results of the phase transitions.The model can truly reflect the traffic situation. |
| Key words: cellular automaton phase transition local density order parameter |
