【摘要】：针对城市公共自行车系统(PBS)依靠人工经验规划服务点布设导致的"租还车难"问题,根据PBS的运行特性,借鉴有限元原理,研究PBS不同空间位置区域的供需不平衡度有限元估算模型,建立PBS服务点布设的有限元估算方法.以杭州市部分区域为例,应用有限元分析软件ANSYS对估算方法进行验证.结果显示:在研究区域内未建服务点4146时,公共自行车供需不平衡度最大的位置位于120.151 275°E~120.152 55°E和30.302 04°N~30.303 774°N;建立服务点4146后,该位置的供需不平衡度明显缓解,单元供需不平衡度最大的位置与服务点4146实际位置相比,经、纬度误差分别为0.044 5%、0.047 3%.分析结果表明,该估算方法能够有效分析PBS的单元供需不平衡度,从而有助于服务点的科学布设.
[Abstract]:In view of the problem of "difficult to rent and return vehicles" caused by the establishment of service points of urban public bicycle system based on artificial experience, according to the operation characteristics of PBS, the finite element principle is used for reference. The finite element estimation model of supply and demand imbalance of PBS in different spatial locations is studied, and the finite element estimation method of PBS service point placement is established. The finite element analysis software ANSYS is used to verify the estimation method. The results showed that the largest imbalance between supply and demand of public bicycle was located at 120.151 275 掳E 120.152 55 掳E and 30.302 04 掳N, 30.303 774 掳N, and the imbalance between supply and demand was obviously alleviated after the establishment of service point 4146. Compared with the actual position of service point 4146, the latitude error of unit supply and demand imbalance is 0.044 5 and 0.047 3 respectively. The analysis results show that this method can effectively analyze the imbalance between supply and demand of PBS units, which is helpful to the scientific layout of service points.
