Metodología para la clasificación funcional de carreteras primarias y secundarias de una calzada en Colombia

Abstract

The road infrastructure in Colombia is currently functionally classified according to the guidelines contained in Resolution 411 of 2020, which establishes technical criteria for categorizing roads at the national level but lacks specific parameters that define their capacity. This study will propose a methodological approach that will allow the functional categorization of primary and secondary roads in the country, establishing a clear roadmap to ensure optimal design and operating conditions in Colombian two-lane highways, identifying deficiencies in the classification process based on information available internationally, as well as the guidelines contained in the Highway Capacity Manual (HCM) of 2022, adjusting them to national conditions and evaluating technical criteria such as topography, traffic and layouts to subsequently analyze the influence of these on the final sizing of the road infrastructure. Concluding that the existing infrastructure at the national level is oversized or undersized with respect to the hourly volume of demand in terms of traffic, which requires adjustments in the geometry of the road corridors and therefore in their capacity.
