It is wellknown that modalshift among several transportation methods is governed by the delivery time and the transport capacity of each mode as well as their freight rates. In the former paper, the authors dealt with a modelling approach to the consigner preference structure of modalshift. This paper shows that the modified mixed integer linear programming model for modalshift is proposed to include the transport capacity other than transport cost and investment cost, and the attempt was made to interprete the mathematical model for modalshift geometrically how the breakeven analyses are made among several modes when their fixed and variable cost data are available. The results are discussed with case study analyses.
