基于虚拟现实的高寒地区高速公路设计与评价模型研究

Research on expressway design and evaluation model in high cold regions based on virtual reality

文章以辽宁沈阳某高速公路为研究对象,采用OpenRoads Designer软件对高寒地区高速公路设计与评价模型进行了研究。结果表明,根据在建沈阳某高速公路现场勘查资料、施工图统计,构建该高速公路完整路段道路和场景模型、高速公路安全设施模型,生成高速公路虚拟模型。分析该高速公路道路线形,确定包括控速设施、配套标志公路安全控制系统,建立虚拟模型,将安全设施模型在虚拟道路模型中应用,在人车路联合运行仿真平台上进行实景模型驱动。构建高速公路项目评价模型,分析表明,高速公路模型调查问卷信度和效度较好,可以体现出较好的拟合度,在建设高速公司项目时应用该模型可以提高准确性与可靠性。

This paper takes an expressway in Shenyang as the research object,and uses OpenRoads Designer software to study the design and evaluation model of expressway in cold regions.The results show that according to the on-site survey data and construction drawing statistics of an expressway under construction n Shenyang,the Ioad and scene model of the complete section of the expressway,the expressway safety facility model and the expressway virtual model are constructed.The construction of expressway project evaluation model shows that the reliability and validity of the expressway model questionnaire are good,the model fitting is good,and the use of this model for expressway construction projects is reliable and accurate.
