在更新法国城市高速公路设计指南的总体框架内，进行了一些研究，以建立一个新的模型，在入口匝道的交通运行。其中之一，在本文中描述的，旨在收集一般知识的合并过程中，从微观交通数据收集的分析仪表郊区高速公路段。该设备提供车辆轨迹，每隔50米取样一次。在第一步中，已经建立了关于车道使用和运行速度的经验证据。然后，车辆的相互作用进行了研究，以计算在合并位置的风险指标，并作为交通环境的函数合并概率建模。最后，提出了正在进行的工作和展望。
Within the general framework of updating the French design guidelines for urban freeways, some studies are conducted for building of a new model for traffic operations at on-ramps. One of them, described in this paper, aims to gather general knowledge on the merging process, from the analysis of microscopic traffic data collected on an instrumented suburban freeway segment. This equipment delivers vehicle trajectories, sampled at a 50 m interval. In a first step, empirical evidence on lane use and operating speeds has been established. Then, vehicles interactions have been studied, so as to compute risk indicators at merging locations, and to model the merging probability as a function of the traffic environment. On-going works and perspectives are presented to conclude.
