Abstract in Portuguese
Este trabalho avalia a influência de veículos de grande porte na capacidade de interseções rodoviárias em nível não semaforizadas, verificando as variações no comportamento de caminhões e ônibus durante manobras de cruzamento, em função de seu comprimento e de sua relação potência/peso. Foram realizadas análises das distribuições dos tempos de cruzamento e da aceitação de "gaps" por diferentes tipos de veículos, sendo utilizados modelos Logit para representar o comportamento desses veículos nos cruzamentos. Estes modelos serviram como base na elaboração de um simulador, para determinar a capacidade potencial das interseções e para calcular os fatores de conversão de veículos de grande porte em veículos de passageiro.

Abstract in English
This study assesses the influence of heavy vehicles on the capacity of unsignalized rural intersections. This is done through the study of vehicle behavior during crossing maneuvers that can be attributed to length and power-to-weight ratio. Crossing time distributions and gap acceptance of diferent types of vehicles were analysed, and Logit models were used to represent their behavior. These models and a simulation model were used to determine the potencial capacity of intersections and to calculate factors to convert heavy vehicles into passenger vehicles.
