Subsídios à tomada de decisão da escolha da modalidade para o planejamento dos transportes no estado do Paraná

The marketing chain of grains and soybean meal live together with the geographical separation between production and consumption or export in the State of Paraná, Brazil. The improvement of the transport services supply is an important tool in the construction of the competitiveness of the commodities, in whose markets prevails as competition pattern the price. This study used rationalization models about the transport infrastructure, based in freights, to beacon the evaluation socially between the modal distribution desirable and that indeed observed. The obtained results signalled for the quite significant increment in the use of the railroad transportation. Due to the deviation in relation to the situation indeed observed, one suggests that there is the need of efforts associated to the rail transport, such as punctuality, losses and general conditions of packaging, what perhaps has more means of being implemented in face of the deprived administration of the railroads of the State of Paraná. That could converge interests peculiar of the users and public interests.
