Soybean is a commodity that has an important influence on the Brazilian economy because it accounts for the largest share among the grains in the export market. Its main production centers excel in regions far from major consuming centers, requiring long commutes especially in road transport. The distance is the most influential factor in transport costs and is directly related to the freight. To define actual road distances, particularly in unfamiliar roads, it is necessary to use a correction factor. In addition to estimating a better correction factor, the paper aims to contribute by developing a procedure to identify this factor. This paper will analyze the relationships between existing Euclidean distances in numerous points, the producing centers and Brazilian's ports, performing comparisons between the correction factor obtained by calculation in this article with the factors obtained by other authors, also seeking to relate the road distances calculated based on intervals and freight. The advantage of obtaining a more accurate factor k is to allow the results of different location, such as p-median be more accurate. The result was satisfactory when comparing with the existing literature.
Entre 2008 e 2014, foram desenvolvidas, no Rio de Janeiro, algumas iniciativas na tentativa de reduzir os problemas de transporte urbanos em comunidades carentes, como a instalação do teleférico no Complexo do Alemão. Porém, o número de passageiros deste serviço é muito baixo em relação à sua capacidade. Neste contexto, este trabalho apresenta uma análise da acessibilidade às estações do teleférico, com base em uma pesquisa realizada com 100 residentes do Complexo usuários do sistema. A análise estatística (teste t, análise de variância e de clusters) foi realizada para comparar as percepções dos passageiros de diferentes estações com o objetivo de identificar se as características do entorno influenciam a decisão de usar o teleférico. Os resultados indicam que, segundo as percepções dos passageiros, a baixa acessibilidade física, a falta de infraestrutura local e a não integração com os serviços de transporte complementar existentes colaboram com o atual padrão de demanda.
