| 摘 要： | 非接触式交通检测技术具有检测范围大，安装维护方便等优点，在高速公路动态交通数据采集中不断得到应用。本丈在分析各种非接触式检测技术特性和精度的基础上，通过现场实验，研究了非接触式检测技术的应用功能、基于微波一线圈的组合应用及其数据融合。实验结果表明，非接触式交通检测技术在高速公路动态数据检测中可以使用，但由于受检测精度、数据类型、范围与安装使用条件的影响，不宜单独使用；通过非接触式与接触式检测技术的组合应用，克服了接触式检测器难以维护的缺陷，并且多检测技术数据融合的检测精度比单一检测技术提高10％～15％。

| Abstract: | Traffic non-contact detection technologies have the advantages of wide detection ranges,convenient installation and maintenance, so, they have been widely used in dynamictraffic data acquisition on expressway. On the basis of research of the characteristics and precision of various non-contact detection technologies, the application function of the technologies, the combined application and data fusion based on microwave-coil are studied by means of field experiment. The results indicate that traffic non-co... |
