Title An Analysis of the Changes in Spatial Structure for Travel Demand Based on Census Data
Author Tien-Pen Hsu and Pei-Rong Wu
Summary

  Population accumulation and regional disparity caused by rapid economic growth and industrial transformation have become more and more important issues all over the world in recent years. The fast economic growth in Taiwan led to increases in various aspects: the national income, purchasing power, demand for motor vehicles, and consequently the mobility of citizens. All of these changes directly or indirectly caused migration, relocation of residential and industrial areas, and spatial restructuring. This paper analyzed the original population and housing census data in 1990 and 2000, to explore the trend of changes in spatial diffusion and centrality due to working trips among the working population as well as the changes of commuting behavior. Entropy and Gini coefficient were used as indicators to measure the spatial structure changes. Furthermore, relative divide was used to investigate the reasons and groups that caused the centralization and verify the causes of disparity. The aim was to provide references for related government agencies in formulating policies and setting targets. This information helped to reduce the development gap and achieve the goal of balanced regional development.

  The results revealed a trend of centrality of the spatial changes due to working trips among the total working population in Taiwan from 1990 to 2000. In addition, the proportion of working trips increased and commuting distance became shorter when workers reside and work in the same township.
