碩士 / 國立成功大學 / 交通管理(科學)學系 / 84 / The transportation planning processes in practice emphasize
passengerproblems much more than freight problems. The freight
demand models that havebeen used in planning process are very
simple and primitive. However, there are many theoretical
studies of freight demand have been done in the past , butthe
models developed in these studies have not been applied in
transportationplanning. Major reasons for that include lack of
disaggregate freight data andlack of adequate analytical method.
This research attempts to present a comprehensive framework for
freight demand analysis and forecast. This framework serves as a
basis for developing a operational process to analyze the
practicalfreight transportation problems. The framework and
method proposed in this research involve input-output theory and
inventory theory. The use rate of freightas input for production
for each industry and firm can be estimated throughinput-output
relationship using public available data sources. Using
waybilldata of railroad and highway and the estimated use rate
data, short-term freighttransportation policy analysis can be
performed. This method not only solvesthe problem of lacking
data, but also provides theoretical background to freightdemand
analysis in practice. Empirical analysis in our study indicates
thatthe proposed method is feasible to be used in transportation
planning process.The empirical analysis of this research
emphasizes the short-term mode choicebehavior of firm.
Sensitivity analysis indicated that the choice of mode willnot
easily be changed simply by fare adjusted. For a firm to use
rail to shipment its input material requires several important
factors, such as large use rate of the input material, long
distance of shipment, existence of rail siding, etc.
