如今,相图被广泛用于交通科学领域的研究,取得了重要成果。根据理论分析和计算机模拟,本文构建了十字路口处交通流量相图。该相图是由五个基本区域构成的,本文分析并推导出每个区域的具体流量公式。在周期边界条件下,采用确定性 Fukui-Ishibashi元胞自动机交通模型进行数值模拟,其模拟结果与理论分析精确一致。

Phase diagrams are now widely used in the study of transportation science and important a‐chievements have been obtained .Based on theoretical analysis and computer simulations ,phase dia‐gram has been mapped out which consists of five regions .Analytical formulas of the flows have been derived and obtained in all the five regions .In simulation ,the deterministic Fukui -Ishibashi cellular automaton traffic model is adopted under the period boundary .The numerical results are in good a‐greement with theoretical analysis .
