中文摘要： 在车路协同技术研究取得显著成果步入新的应用阶段背景下，如何将已有的研究成果应用于现有城市智能交通系统是现阶段亟待解决的现实问题，而车路协同技术的实验方法对测试、完善其可实施性尤为关键。针对目前车路协同技术测试研究以多仿真器联合仿真和大范围外场实地实验为主，存在无法体现车路间实际协同特征和实验部署难、费用高等问题，本项目在非完备信息交通环境特征解析基础上，设计适合车-路-智能终端等协同智能体信息特征的多源异构数据质量控制方法和融合模式；考虑信息缺失、传统交通与车路协同技术共存等非完备信息环境，研究实现外场实际车路场景模型与通信仿真网络中信息协同机制深层耦合的半物理仿真方法；设计实、虚车路对象相互作用的沉浸渲染方法和性能评价指标体系，实现非完备信息环境下车路协同技术的测试实验。本研究旨在为新阶段车路协同技术应用提供一种过渡性的实验仿真方法，对实施智慧城市战略及解决现实城市交通问题具有重要意义。

英文摘要： Under the background of obtaining significant achievements in vehicle infrastructure integration and entering the new application stage, it is an urgent problems in current stage that how the existing research achievements apply urban intelligent transportation system, and experiment method is crucial for testing and improve its implementation. For the current vehicle infrastructure integration technologies focusing mainly on the multi-simulator co-simulation and wide field experiments testing, and having the problems of not reflecting the actual integration characters of vehicle infrastructure, difficult experiment deployment and high cost, the multi-source isomerous data quality control method and fusion pattern suitable for integration intelligent agent information characters of vehicle-infrastructure-intelligent terminal are designed based on the incomplete information traffic environment. Considering incomplete information environment of information absence and the coexistence of traditional traffic and vehicle infrastructure integration, semi-physical simulation method is studied integrating field experiment vehicle-infrastructure scenario model and information integration mechanism of communication simulation networks. Experiment method for vehicle infrastructure integration technologies in incomplete information environment is presented based on the immersion colour method of interaction between actual and virtual vehicle-infrastructure object and performance evaluation indexes. It is the project purpose that a transitional experiment simulation method is proposed for testing the actual performance of new vehicle infrastructure integration technologies, which of great significance for implementing the smart cities strategy and resolving the current traffic problems.
