摘　　要：为了提高智慧高速的运营效率和安全性,本文研究了多元交通感知设备的优化布设方法。以蜀道集团智慧高速建设工程项目中川北片区绵广高速和广陕高速的道路为研究对象,构建考虑行程时间的目标优化布设模型,计算基于均匀布设的行程时间,对智慧高速多元交通感知分级并对设备选型。研究结果表明,在满足一定精度要求的前提下,合理的布设间距和感知设备选择能够有效降低布设成本,提高智慧高速的运行效率。因此,在实际应用中,应充分考虑感知设备的性能、布设间距和交通流特性等因素,以实现感知设备的优化布局。In order to improve the operational efficiency and safety of smart highways,this paper studies the optimization deployment method of multiple traffic perception devices.Taking the roads in the smart highway construction project of Shudao Group as the research object,a target optimization deployment model considering travel time is constructed,and the travel time based on uniform deployment is calculated.The intelligent highway is classified into multiple traffic perception levels and equipment selection is carried out.The research results indicate that,under the premise of meeting certain accuracy requirements,reasonable deployment spacing and selection of sensing devices can effectively reduce deployment costs and improve the efficiency of intelligent high-speed operation.Therefore,in practical applications,factors such as the performance of perception devices,deployment spacing,and traffic flow characteristics should be fully considered to achieve optimized layout of perception devices.
