| 摘 要： | 以往传统的交通分析方法,将大量的交通信息堆砌在一起,如时间信息、空间信息等,忽略了信息间的相互作用,割裂了交通系统的整体性和系统性。说明了出行链对交通分析和交通规划的重要作用,从交通现象的本质出发,给出了出行链的结构和定义,提出了出行链特征指标,以“链”的形式将交通系统的时间维、空间维、方式维和活动类型联接在一起,将交通系统变成一个有机的整体。并通过多项Logit模型建立了交通方式选择模型,在模型拟合良好的前提下,验证了平均出行链长度和换乘次数对方式选择的影响是显著的。

| Abstract: | Based on the fact that the integrity and systematicness of the transportation system are cut apart, with the interactions among pieces of information ignored in the conventional travel analysis methods, even though there exists a plenty of information available, such as related to time and space, this paper explains the importance of trip-chains on travel analysis and transportation planning. And according to the essence of transportation phenomenon, correlative concept, structure, indices and definition are put forward. Time dimension, space dimension, mode dimension and activity type are linked by trip chaining, which make transportation system as a organic whole. And transportation mode choice is set up by multinomial Logit model. Based on fine goodness of Model fit, the influence of average length of trip-chain and transfer number on mode choice is remarkable. |
