This study explores the impacts of the freeway on the change
of local population and employment in the neighboring
interchange area with the cases study of Chung-Sun Freeway and
3rd national freeway.
First, this study analyzes the growth trend of local population
and employment. Second, the time-series model is established to
test the effects on the local population and employment caused
by the freeway. Finally, it analyzes and explains the impact
level, time and scope.
In model analysis, this study shows the impacts of the freeway
, i.e. growth rates of local population and employment, on the
canton where the interchange locates, remains uncertain, whereas
those on the neighboring interchange area are positive. The
study also reveals that the impacts of the freeway on suburban
inter- change area are higher than those on metropolitan
interchange area. Besides, the impact level of the canton where
the inter- change locates is the highest than the other area .
As for the impacts by the periods of time, the grow rates of
population and mployment significantly increase in the period of
the opening of the freeway, although the growth rate of
population has dropped in the period of construction. In the
industry, the impacts on secondary and tertiary industry in the
neighboring interchange area are significantly positive,
especially for the manufacture and public utilities among
secondary industry, and for the commerce and financing,
insurance, real estate and business services among tertiary
industry.
