摘要

過去在從事運輸需求的研究時，常以都會區的需求模式應用於城際間，但由於城際旅次和都會區內旅次的旅次的發生特性差異很大，故以都會區模式來描述此一現象，不甚合理，本研究應用IPTD model於台灣地區，並逐次修正，且在模式中放入都市地區虛擬變數及旅行時間門檻虛擬變數，模式以非線性方法校估；另外本研究依直接需求模式的架構，校估台灣地區旅次產生及分佈模式，並和本研究修正IPTD model作比較。

There are many major transportation development projects under planning and construction in Taiwan. Transportation systems will be facing a dramatic change in the future. However, the conventional travel demand analysis fails to give adequate consideration to such change.
The aim of this paper is to develope a model which shows how intercity trip generation and distribution are affected by reducing travel time between cities. The model based on Intra-provincial Trip Distribution (IPTD) model. The parameters in the model are calibrated by nonlinear approach. Two dummy variables, urban hierarchy and travel time threshold, are found to play key role in long distance travel decisions.
In addition, the research compares the results of IPTD model and conventional model. The comparisons involve calibration of the direct demand model using same set of variables but different model structure.
