摘　　要：利用浮动车系统提供的车辆定位数据进行新增道路检测,可有效提高新增道路的检测效率,降低成本。提出了浮动车与空间网格结合的新增道路自动检测算法,首先记录车路匹配不成功的浮动车位置数据,得到可表示疑似新增道路的浮动车轨迹点。然后建立起浮动车轨迹点与路网网格之间的对应关系。最后通过网格过滤实现新增道路自动检测。实例验证了该算法的可行性。The new roads detecting method utilizing the location datum of floating car system can improve efficiency and reduce cost of the new road detection effectively. A algorithm combining the floating cars with space grid for automatic detection of new roads is presented. Firstly the unmatched FCD points are recorded by the vehicleroad matching, which can be represented as the suspicious new road. Then the relationship between these points and road network grid is built up. Finally, the new roads can he automatic detected with the grids filtering process. The example demonstrates that this algorithm is feasible.
