| 中文摘要: |
| 为了提出探究城市快速路交织区交通特点，提出交织区运行风险预测分析方法。本文首先基于城市快速路交织区断面线圈数据及自然驾驶试验数据，分析了城市快速路交织区运行特点，结果表明交织区车辆变道行导致其运行风险增大；然后基于VISSIM仿真试验方法，分析了交织区运行风险影响因素，建立了运行风险预测模型，同时采用K均值聚类分析法提出了风险分级标准；最后采用无人机采集的交通流数据进行了运行风险预测模型误差分析。本文可为城市快速路的设计管理提供工具和参考。 |

| In this paper, the traffic characteristics of urban expressway weaving area was analyzed based on the loop detector data and the natural driving data. Then, the operation risk evaluation model of the weaving area was established on the strength of VISSIM traffic simulation method and the K-means clustering. The drone aerial data was used to verify the feasibility of this model in the end. The results show that the operation risk evaluation model of urban expressway weaving section operation risk is feasible to evaluate this area risk. This paper provide reference and basis for the research and implementation of the operation risk assessment of urban expressway weaving section. |
