【摘要】：針對城市公共自行車系統(tǒng)(PBS)依靠人工經(jīng)驗(yàn)規(guī)劃服務(wù)點(diǎn)布設(shè)導(dǎo)致的"租還車難"問題,根據(jù)PBS的運(yùn)行特性,借鑒有限元原理,研究PBS不同空間位置區(qū)域的供需不平衡度有限元估算模型,建立PBS服務(wù)點(diǎn)布設(shè)的有限元估算方法.以杭州市部分區(qū)域?yàn)槔?應(yīng)用有限元分析軟件ANSYS對估算方法進(jìn)行驗(yàn)證.結(jié)果顯示:在研究區(qū)域內(nèi)未建服務(wù)點(diǎn)4146時(shí),公共自行車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;建立服務(wù)點(diǎn)4146后,該位置的供需不平衡度明顯緩解,單元供需不平衡度最大的位置與服務(wù)點(diǎn)4146實(shí)際位置相比,經(jīng)、緯度誤差分別為0.044 5%、0.047 3%.分析結(jié)果表明,該估算方法能夠有效分析PBS的單元供需不平衡度,從而有助于服務(wù)點(diǎn)的科學(xué)布設(shè).
[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 擄E 120.152 55 擄E and 30.302 04 擄N, 30.303 774 擄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.
