methodology proposal for accessibility analysis of a road corridor for freight transport

In recent years changes in freight transport demand, both locally and internationally, have significantly increased cargo flows to and from logistics centers. as a result, it is essential to develop effective methods for assessing freight accessibility to road corridors designated for land cargo transportation. this paper proposes a methodology that facilitates the freight accessibility analysis to a road corridor for land cargo transportation. the accessibility analysis considers several key variables such as the mobilized tons, the overall conditions of the roads, the route lengths connected to the corridor, and origin-destination nodes associated with the productive chains mobilized by this transportation mode. we validate the methodology through a comprehensive case study conducted in colombia. the results reveal road corridors such as llanos de cuivá (yarumal) - la apartada (córdoba), and soledad - barranquilla present the lowest accessibility measure and require infrastructure investments to enhance road corridor accessibility and promote the efficient transportation of goods. furthermore, it offers valuable insights into characterizing areas with significant cargo generation and reception, enabling targeted improvements in transportation industry responsiveness.
