This paper presents an analysis of which functional form of Travel Time Value is appropriate to the estimation with binomial logit random factors model. In order to do this, it will make an estimation methods overview, describing some structured functional forms as Tuong and Hensher (1985) for...

Efficient use of the transport systems can increase well-being and ensure gains for the society. The reduction of the costs involved in transport operation can occur through management, investments or using more efficient infrastructures. Well-being gains are weighted based on economic theory,...

Freight trip generation models essentially use the least-squares estimation technique, losing in part the power of weighted least squares, least squares techniques in two stages, and instrumental variables that could address the complexities of the transport phenomenon that has repercussions in...

The Brazilian ports are out of capacity, imposing several restrictions to the sector expansion. Some investments have been made, but without improvements in the situation. Ports around the world seems to have the same problem. One of the aspect that implies in this situation are the forecast...

This paper aims to apply, to the maritime ports demands in Brazil, the intervention impacts technique, purposed by (Box, G. E. P. e Tiao, G. (1975), Intervention Analysis with Applications to Economic and Environmental problems, Journal of the American Statistical Association, 70, 70-79). As...

Ten years of financial stability in Brazilian economy have gone. In this period, the regional transportation of passengers suffered exogenous impacts: economical crises, airport crises and great proportions' accidents, as well as impacts which were intern to the system: institutional changes...

To address the need for a better understanding of cooperation, coordination and competition among transportation modes identified by various research studies, this paper sets out to analyze port-railroad relations of cooperation and coordination in the Brazilian case and the possible existence...

The duality between cost and production function can be a key point to explore regulation process in Agent-Principal model because the Principal observes outputs in inputs and has asymmetric information about the cost by the Agent. This paper investigates the properties of production functions...
