基于差分GPS的道路线形质量评价

The quality evaluation of road line based on difference GPS

为了提高道路线形质量,提出了利用差分GPS与航位推算组合定位技术和计算机技术计算道路轨迹参数的思路,对DGPS/DR定位系统的数据采集与处理、汽车行驶轨迹参数的计算、汽车行驶轨迹与道路线形的差异性进行了分析。

In order to improve road line quality, the ideas of reckoning combined orientation technology using defference GPS and navigate position and calculating road line parameters using compute technology were provided, the data collection and treatment of DGPS/DR positioning system, the calculation of car traveling track parameters, the difference between car traveling track and road line were analyzed.
