| 摘 要： | 交织区长度是影响交织区运行特性的重要参数,影响着交织车辆进行车道变换的紊动程度。找出了车道变换频率与其相应产生的车道变换长度的一一对应关系,定义了车道变换长度随机变量,通过分析给定交织区车道变换长度的统计分布来反映交织操作车道变换的频度。在其他因素不变的条件下,运用动力学理论、概率论等方法定量分析了交织区长度对车道变换产生的影响。 |
| 关 键 词： | 交织区长度 车道变换 车道变换长度 累积分布 |

| Abstract: | A numerical analysis of impact of weaving length on change-lane frequencies within a weaving area is deemed challenging. This paper identifies a corresponding relationship between change-lane frequencies and the cumulative probabilities of change-lane lengths by introducing random variables of change-lane lengths. Through a statistical study of change-lane lengths within a Type A weaving area, the cumulative probability of change-lane lengths is obtained, and thus the impact of weaving length on change-lane activities within the weaving area is quantified, The study lays a theoretical basis for design of weaving areas and for further research on their operational characteristics. |
| Keywords: | length of weaving area change lanes length for change lanes cumulative distribution |
