摘　　要：以宁波市公共自行车系统为例,分析了公共自行车租赁时长与租赁频率的基本特性,并引入了交通性出行行为与非交通性出行行为的概念。在此基础上,基于通信系统中信号滤波的原理,将公共自行车出行中的租赁时长和租赁频率分别比拟为通信系统中的信号频率和信号振幅,利用巴特沃斯低通滤波器原理建立了公共自行车交通性出行行为分析模型。最后,利用该模型对宁波市公共自行车租赁特性进行滤波分析。结果显示,在公共自行车出行需求中,当租凭时长大于35 min时,以非交通性出行为主;当租凭时长小于20 min时,以交通性出行为主。得出了交通性出行行为的公共自行车租赁时长分布函数。The basic characteristics of rental duration and rental frequency of the Ningbo public bicycle system is analysed,and the concept of internal travel behavior and non-internal travel behavior are presented. Based on the signal filtering principle of communication system and by taking the rental duration and the rental frequency of the public bicycle travel as the signal frequency andthe signal amplitude respectively,the public bicycle internal travel behavior analysis model is built using the principle of Butterworth low-pass filter. Lastly,the filtering analysis of Ningbo public bicycle rental characteristics is given. The result shows that,when the rental duration is longer than35 min,the non-internal travel is the main demand in the actual travel; when the rental duration is shorter than 20 min,the internal travel is the main demand. And the rental duration distribution function of internal travel is also provided here.
