Summary         The current approach to freight demand analysis and transportation planning mainly follows the framework of passenger transportation planning, where freight demand generation and distribution are forecasted by a simplified growth
rate method. The forecasted freight demands are then converted into truck trips and used as the background traffic flow for conducting the traffic assignment of passenger demands. Obviously, the current approach is not able to properly reflect the trends of industrial development, nor the rapid growth of newly emerging logistic services. Without knowing the relationship between industrial development and logistic service to road traffic, it is impossible to propose policy strategies
that meet practical needs. The government may find it difficult to gauge the scope and degree of the impact of freightrelated transportation issues on road traffic.
       Therefore, based on the overall Taiwan area comprehensive transportation planning model and in light of the literature review, this study proposes a new freight transportation planning framework comprising three modules: import-export
freight, intercity freight, and city freight. The methods developed in the literature for freight demand analysis and transportation planning in these modules are also reviewed and summarized. In order to coordinate with the overall Taiwan
area comprehensive transportation planning model, this project specifically concentrates on the import-export and intercity freight modules. The import-export freight module adopts an input-output model and aggregate logit model to predict the future import/export freight volume for each seaport and airport. Meanwhile, the intercity freight module integrates the forecasted results of the import-export freight module into a commodity-based four-step freight transportation planning
model to predict intercity freight trips. The predicted freight trips will be integrated with the passenger trips predicted by the passenger transportation planning model for traffic assignment.
        To assess the practical feasibility of the proposed model, a case study focusing on the commodity of sand and gravel products was conducted. The project outcomes include literature reviews, analysis of case studies, exploring trends in freight
development, conducting corporate interviews, expert and scholar roundtable discussions, as well as case analysis focusing on sand and gravel products. The research outcomes have led to proposed research topics, priorities, and yearly
implementation suggestions for future freight demand analysis. These results can serve as references and guidelines for the government in developing freight transportation strategies and policies.
