车路集成系统探测车数据采集仿真研究

Study on Vehicle-infrastructure Integration Probe Data Collection Simulation

在解析车路集成系统探测车数据采集过程和基本规则的基础上,提出了基于VISSIM商业仿真系统组件对象模型接口对车路集成系统探测车数据采集进行仿真的方法,并开发了相应的仿真原型系统。该原型系统通过在VISSIM仿真平台上嵌入路边设备和车载设备功能,可以灵活地描述路边设备分布、车载设备瞬时记录触发时刻、车载设备标识码、瞬时记录留存策略等探测车数据采集参数的取值和确定方法,从而可真实地模拟车路集成系统以"车载设备移动检测,车路数据交互"为特点的数据采集过程。

Based on the parsing of Vehicle-Infrastructure Integration probe data collection process and basic rules, a VII probe data collection simulation methodology through the COM interface of a commercial traffic simulator, named as VISSIM, was put forward. The corresponding simulation prototype was then developed, which, by integrating the functions of Roadside Equipments and On-Board Equipments into FISSIM simulation platform, can flexibly describe the values and determination methods of probe data collection parameters such as Roadside Equipments spacial distribution, On-board Equipments snapshots trigger time, On-board Equipments 119, snapshots retention strategies, etc., thus can accurately simulate the Vehicle-Infrastructure Integration data collection process featured with ＂On-board Equipments floating sensing and vehicle-infrastructure inter-communication＂.
