RESUMO

The main goal of the master dissertation is to verify and to analyze the influence of geometric characteristics of road sections on highway users’ costs, in terms of vehicle operation costs and costs associated to travel time, using the software HDM-4 (Highway Development and Management). The study was initiated with the creation of seven sections representing the HDM-4 highway geometric classes, and nineteen sections with geometric characteristics defined to allow a sensitivity analysis of parameters associated to vertical and horizontal alignments. Four sections were selected from Washington Luiz highway (SP-310), representing highways with distinct geometric characteristics. The computer simulations were performed considering a scenario that includes: traffic flow pattern, road class, average daily traffic and traffic composition, pavement type and condition, among others. The study calculated the effects of highway geometry on each component of users’ costs. The costs of earth work and paving were calculated aiming at the comparison between costs of geometric improvements and benefits associated to that. The results showed that highway geometry may have a great influence on users’ costs and, therefore, its effects must be considered in highway construction and maintenance projects assuring more benefits to society.
