Radios de giro en camiones articulados para diseño vial urbano en Colombia

Abstract

Currently, Colombia does not have its own regulations to establish the radios of the existing articulated vehicles that circulate at the national level and more specifically at the urban level, for design development. The radios currently used are those contemplated by the AASHTO 2004 regulations, which present a certain difference with respect to the Colombian automotive fleet, although it is true that it is an international standard, the necessary space for the turning maneuver must be guaranteed without having that to resort to additional maneuvers, guaranteeing constant operations and reducing in important proportions the vehicular congestions. These radios vary depending on the lengths of the design vehicles, and even more important, the direction and speed with which the turns are taken. As defined by the Road Design Manual 2008 of Colombia, the design vehicle is a vehicle representative of all vehicles that can circulate along said road and must correspond to the vehicle composition defined in the traffic study, in the same way it is important to have the geometry of the track, width of berms, widening and minimum radius of rotation. The present work intends to propose a methodology that allows to solve one of the main problems in terms of vehicular operation that is presented at urban level, giving continuity to the research carried out by the Engineer Mario Arturo Rincon Villalba, who contemplated in his thesis "DETERMINATION OF SPINNING RADIOS FOR URBAN VIAL DESIGNS IN COLOMBIA ", the radios required for light vehicles existing at the time. With this project will determine the dimensions of the articulated vehicles C3-S2 and C3-S3, which circulate at urban level, from these dimensions and with field studies, determine the respective radii of rotation and their corresponding graphs, in order to complement the existing automobile park in Colombia and to be able to later propose a methodology that optimizes and improves some road designs in the country.
