Reestruturação geométrica no trecho da PR-444 em cruzamento a rua tangará e estrada aliança na cidade de Arapongas-PR

Abstract

The urban expansion, and consequently the increase in circulating vehicles impact directly on the road systems. The city of Arapongas, comprises a stretch of the PR­-444, state highway that separate the dense urban area from the rural area, however, with the expansion and demand of vehicles increasing, the actual road system, intersections and crossings are becoming obsolete and unsafe for the population. The rural area separated by the highway is expected to be expanded with two popular constructions within two years, so there is not study on the suitability of the stretch that connects this two parts of the city. Based on this premise, a traffic study was carried out, analyzing the capacity of intersection, volume of vehicles per hour that circulate in all directions, aim of enabling an interconnection on this road. If a intersection in level are not being able to promote basic safety to an road, it must be replaced by a slope intersection, a solution chosen and adapted according to the normative guidelines. Executing and sizing a geometric projection for a possible solution, was possible to see the difficulties found in carrying out this adaptation, so that the simulated numbers of future traffic, and with the expansive tendency of the increasing of the population, more adaptations may also be required in the future.
