Impacts of Modal Competition and Intermodal Capacity on Transport Supply

• Modal competition. On the first example (1), two modes (A and B) are sharing the same transport infrastructures. Assuming that they are using the infrastructures to their full capacity, their common demand, T(A) and T(B), is equal to the capacity C. Any change in one mode will be done at the expense of the other.
• Intermodal capacity. On the second example (2), two terminals (A and B) have a respective capacity of C(A) and C(B). The maximum transport demand possible between them, T(AB), is equal to the capacity of the smallest terminal, C(B).
