CONCEPTUAL REVIEW
Aspects of modal shift
In this article are considered the main regional development and geography of
transportation, proposed by Rodrigue; Comtois; Slack (1999), Blauwens et al. (2006)
examines the influence of total logistics costs and Ogawa (2004) emphasis on the
environmental benefit, considering that the exchange of modal will reduce the emission of
carbon dioxide, Geerts (2002) deals on the market for modal shift in intermodal transport.
Bravo (2000) refers to the multimodality, focusing on theory of cost transshipment port.
Geerts (2002) proposes the adoption of IPI (Intermodality potential index) which
measures the intermodality potential from the equation of division between potential and
current market of the intermodal transport, which influential factors are: transfer costs; door
to door delivery time; frequency; information tracking (delays); reliability; distance.
Rodrigue; Comtois; Slack (1999) take it that the analysis factors include the distance
but include also the logistics costs and available modal options, as laid out below.
Consequently, they defend a holistic analysis for the decision making progress, meaning
analyzing the distance, operational logistics costs and finally choose the modal options.

As per Jolic; Strk; Lesic (2007) the distance is the main factor for the decision of
adoption of intermodality considering that the strategic planning can only be defined from the
geographical position of the port up to the hinterland. According to the authors, what is
decisive for the port situation are the high additional transport costs (caused by the difference
between the minimum and maximum distances of transport) which are complementary or
contrary to the cargo transfer costs in the ports, i.e., the strategic positioning can be adopted
as a tool for analysis of the port competitiveness, which also depends on the infra-structure
for the definition of modals and the modal transfer as a whole.
The strategic planning can be adopted as a analysis instrument of port
competitiveness combined with the infrastructure to define mode and modal shift. To
Rodrigue; Comtois; Slack (1999) the modal transfer occurs when a modal (a) has a
comparative advantage on another (b) in a similar market. The competitive advantages are
