The search for materials which do not unduly the environment by reducing the cost of production is increasing throughout the world. In the construction sector, concrete is the most consumed material in the world. Its production with bamboo fiber addition can contribute to minimize environmental impacts and production costs by reducing the extraction of natural resources. This study aimed to investigate the mechanical properties of bamboo located in the region of Porto Nacional -TO, Brazil and its application as a binder (Portland cement) in the production of concrete. The research aimed at results that allowed to verify the behavior of the concrete in relation to its uniaxial compressive strength at 28 days of the specimens produced with the addition of bamboo fibers, replacing the cement binder. Bamboo fibers and aggregates were characterized and evaluated according to the material and defined by the trait (1: 1.68: 2.68: 0.482), with replacement percentages set at 3%, 4% and 5%. Therefore, through the tests that were performed, the possibility of replacing the Portland cement binder with natural polymeric bamboo fibers was verified, which proved to be viable and quite advantageous not only for the environmental and economic, but also in the material strength gain.

This paper aims to perform an intersection analysis located in the municipality of Palmas -TO, the location was chosen due to the kneecap is suffering from major congestion at peak caused by the mixture of the traffic of the BR-010 with the urban traffic coming from from the Taquaralto and Taquari neighborhoods. The study site is an area with large population growth and with many traffic generating poles, causing long queues and consequently increasing the accident rate mainly at peak times. This work seeks the current flow of vehicles as well as future estimation, identification of conflict points and their proper origins. The traffic studies have provided the identification of optimal geometry for the roads that intersect in order to seek minimal solutions of boxes and shoulders as well as the ideal number of lanes on the roads and then provide the driver with safer and more comfortable traffic.
