摘要
应用交通动力学分析算法对高速公路偶发性事件影响进行研究,推导出偶发性拥挤下排队率、消散率、最大排队长度、总延时车时数、拥挤下的总通行车时数等参数,并将分析结果与确定性排队分析算法的结果进行了比较,认为本算法能更加准确的分析事件的影响。以算例对这种算法的具体应用、与确定性排队分析方法的具体差别作了说明。
Using traffic dynamic approach the authors analyze the incident affect of freeway. The formulations of the queuing rates, discharging rate, total delay, total travel time etc under the incidental congestion are derived. Also the authors compare the traffic dynamics approach with that of deterministic queuing analysis. The study results demonstrate that the dynamic algorithm is accurate. For the purposes of illustration and verification, a numerical example problem is provided.
