摘　　要：区间测速系统的检测数据是交通主管部门对超速行驶的车辆进行判罚的重要依据。本文基于组合导航技术,分析了区间及其他测速系统的要求,并对其测量不确定度进行评定。同时,将不同的方法进行对比,探讨了组合导航在区间测速系统校准的应用。结果表明:该方法能有效削弱环境因素及复杂道路条件对测速精度的影响,不仅提升了精度,而且测量结果更加可靠。The detection data of the interval speed measurement system is an important basis for the traffic authorities to judge the speeding vehicles.Based on integrated navigation technology,the requirements of interval and other velocity measurement systems are analyzed,and the measurement uncertainty is evaluated.At the same time,different methods are compared,and the application of integrated navigation in the calibration of interval velocity measurement system is discussed.The results show that this method can effectively reduce the influence of environmental factors and complex road conditions on the speed measurement accuracy,not only improve the accuracy,but also make the measurement results more reliable.
