According to the parallel road judgment method and system and the terminal provided by the invention, the track data of the public vehicle is acquired, the road topological structure is generated according to the track data, and whether the parallel road exists in the region or not is judged according to the road topological structure. Road topology is generated based on GPS of buses and taxies on parallel roads, the parallel roads cannot be distinguished by using GPS data of a single vehicle type under the condition that taxies and buses run on the two parallel roads, and bus data lines are fixed, so that the bus data lines cannot be distinguished by using the GPS data of the single vehicle type. The GPS data of the bus and the GPS data of the taxi are considered separately, so that the parallel roads can be distinguished, the GPS track data of the bus and the GPS track data of the taxi can complement each other under the condition that the taxi is driven on both the two parallel roads and only one of the two parallel roads is driven by the bus, the topological structure of the complex parallel roads is extracted efficiently, and the algorithm is simple. Meanwhile, whether parallel roads exist in the road area or not is judged.
本申请提供的平行道路判定方法、系统及终端,通过获取公共车辆的轨迹数据,根据轨迹数据生成道路拓扑结构,根据道路拓扑结构判定该区域是否存在平行道路,上述平行道路判定方法、系统及终端,基于平行道路上的公交车和出租车的GPS对道路拓扑进行生成,对于两条平行道路上都有出租车和公交车行驶的情况,使用单一车辆类型的GPS数据将无法区分平行道路,而公交车数据线路固定,将公交车和出租车GPS数据分开考虑会有助于平行道路的区分,对于两条平行道路上都有出租车行驶且只有其中一条路上有公交车行驶的情况,公交车和出租车的GPS轨迹数据可以互为补充,高效提取出复杂平行道路的拓扑结构,同时对道路区域上是否存在平行道路进行判定。
