The invention discloses a road traffic intelligent accurate positioning system and method based on RTK, and the system comprises the following modules: a traffic supervision center which is used for achieving the cooperative management and linkage operation of road traffic; the mobile positioning module is used for realizing accurate positioning of the mobile vehicle; the road condition monitoring module is used for monitoring the road surface health condition; the auxiliary driving module is used for carrying out auxiliary driving in combination with vehicle positioning and road conditions; the navigation planning module is used for providing real-time traffic path planning and navigation; the user operation terminal is used for providing a user operation and feedback interface; and the fixed base station is used for receiving and transmitting signals and accurately calculating the coordinate position of the vehicle. A partial ambiguity fixing technology is introduced into the RTK positioning algorithm, partial ambiguity to be fixed is removed according to a preset principle when the LAMBDA algorithm fails, and then the residual ambiguity is fixed, so that the positioning precision of the RTK algorithm can be effectively improved.
本发明公开了基于RTK的公路交通智能精确定位系统和方法，包括以下模块组成：交通监管中心，用于实现公路交通的协同管理与联动作业；移动定位模块，用于实现移动车辆的精确定位；路况监测模块，用于监测公路路面健康状况；辅助驾驶模块，用于结合车辆定位及路况进行辅助驾驶；导航规划模块，用于提供实时交通路径规划与导航；用户操作终端，用于提供用户操作与反馈界面；固定基准站，用于接收与发射信号，精确计算车辆坐标位置。通过将部分模糊度固定技术引入RTK定位算法，在LAMBDA算法失效时按照预设的原则剔除部分待固定模糊度，再对剩余模糊度进行固定，从而能够有效地提高RTK算法的定位精度。
