摘要
交通流本身是一个动态过程 ,运用尖点突变理论来分析交通流的预测时只考虑了流量和密度 ,而忽视了时间因素 ,这本身就不是很合理的 .基于这个基础之上 ,采用燕尾突变理论来讨论交通流预测时将时间因素考虑进去 。
Traffic flow is a dynamic process in nature, therefo re , it is not very reasonable that flow and density of flow are only taken into ac count and that time is neglected if cusp catastrophe theory is used to analyze t raffic flow forecast. Based on it, the discussion of traffic flow forecast takes time into consideration by application of swallowtail catastrophe theory, and a numeric example is presented to show that its effect is more accord with realis m.
