Modal Competition, Complementarity and Shift along a
Transport corridors usually offers a variety of modal options with
a linear accumulation of infrastructure. The interactions between these
modes usually take three forms:
- Modal competition. When one mode is
directly competing with another other or with different firms of
the same mode, which is often a zero sum game. Competition can
take place over cost, time, reliability and niche markets. Each
corridor has a passengers and freight balance reflecting their
respective competitiveness level.
- Modal complementarity. When two or more
modes are exploiting their respective advantages over a segment
or an area. Corridors represent a setting where integrated
transport systems through intermodality are particularly
suitable to improve freight mobility.
- Modal shift.
When one mode develops better advantages over existing modes and
captures a share (or the totality) of their traffic. Although
modal shift usually involved a move towards the atomization of
passenger and freight flows (diffusion of automobiles and
trucks), the current trend in urban corridors involve their
massification, particularly through rail transportation.
