Conclusion
This paper has proposed an alternative method to estimate commodity OD matrices between each
individual company of shippers and receivers of the commodities. The model is developed based on the
decision choice behavior of each individual customer on purchasing commodities from each individual
shipper, including factors such as the amount of the commodity generated and attracted by each of the
companies, the distance between the companies, and attractive factors of the shippers. The model is
developed and applied to the case of goods movement in the Tokyo Metropolitan Area.
This study attempts to model freight systems in a multi-agent modeling style with the available data.
As previously stated, one of the main obstacles for modeling freight systems is data availability,
especially when trying to model the system at the microscopic level, where very detailed information on
demand and supply and the transport system are required. A suggestion for further study, therefore,
includes an improvement of the data quality by conducting an additional survey to gather more detail in
the factors involved in the decision.
