“…La propuesta de determinación de estas tasas es más simplista y práctica ajustado a variables socioeconómica centradas en tres variables referida al Producto Interno Bruto, Población, así como Consumo de combustible (Diesel y gasolina). Este planteamiento está acorde a las relaciones establecidas entre el crecimiento de PIB y el transporte, ya estudiado y evaluado por autores como Díaz (2020) La Tasa de crecimiento de población, es de 3.27%, misma que aproxima a los rangos establecidos como mínimo de 2.65%, en promedio incluyendo todos los datos reportados en periodo 2006-2020, y 4.94 % considerando solamente las tasas de crecimiento interanuales o positivas, registradas y reportada por el Banco Central de Nicaragua.

La tasa de crecimiento vehicular es la medida estadística de mayor relevancia para determinar el comportamiento del tráfico futuro, utilizado en el diseño geométrico y espesores estructurales de pavimento. Debido a que las variables indicadoras del crecimiento vehicular en Nicaragua no son sectorizadas se debe normalizar los criterios a emplear en la selección de dichas varíales, así como la metodología para determinar la tasa de crecimiento de diseño vial y su posterior revisión. En este artículo se muestra el análisis de un criterio adicional para la determinación de tasas de crecimiento de forma generalizada es decir al uso de una única tasa para toda la composición vehicular, la cual correspondería a un valor de tráfico normal, proponiendo criterios para su uso y aceptación.

“…This to take measures for the supply of basic necessities; according to the Ministry of Transport ( 2020), one of the first measures that were implemented was the noncollection of tolls on the concessions and non-commissioned roads of the country, seeking to make sure that logistics chains such as production, the supply of basic foodstuffs, imports of basic necessities or agricultural inputs so that they could transport them from the different ports of the country to the production centers in Colombia. and although the city of Bogotá is the main air cargo carrier in Colombia as shown in Figure 8, it was also affected by the decrease in demand for goods nationally and internationally, as reported by Díaz-Olariaga (2021) air cargo transport in Bogotá and in the country, in general, did not collapse completely thanks to the distribution of medical and basic necessities, however, the 75% capacity restrictions had to be applied and aligned with the number of domestic and international flights imposed by the regulatory bodies. Figure 9 shows the number of tons that were transported in the air mode, of which the total is 305,358, from March 19, 2020, which was the date on which confinement began in Colombia, until December 31, 2020.…”

This article's main objective is to identify the incidence of Covid-19 in the processes of internationalization of freight transport services in Bogotá Colombia, this taking into account the importance of internationalization in the face of the challenges that globalization brings to the country in the new scenario that organizations must face regarding the pandemic. Through a descriptive approach and a documentary review, the behavior of the internationalization of this sector, which is so important for the country's economy, as is the transport service, is statistically reflected, showing that although there is a direct incidence of the current pandemic in the sector, it is also clear that this is due to the change in current consumption needs. It is concluded that only those companies that are willing to be in constant evolution are those that despite the difficulties manage to overcome this type of phenomenon successfully.

“…In Colombia, the air transport/aviation industry was liberalized In the early 1990s. This brought about structural reforms in both the airport and airline sectors, all through an uninterrupted battery of public policies (still in force today) that includes not only normative and regulatory aspects but also aggressive public and private investment programs in infrastructure and technology (Díaz Olariaga, 2021a).…”

Airport planning, and therefore the development of air infrastructure, depends to a large extent on the demand forecast for the future. To plan investments in the infrastructure of an airport system and to be able to meet future needs, it is essential to predict the level and distribution of demand, both for passengers and air cargo. In the present work, a forecast was made, in the medium-long term (10 years), of the demand for passengers and air cargo, applied to a specific case study (Colombia), and where the impact on air traffic during the most severe period of the COVID-19 pandemic was taken into account. To achieve this objective, and as a methodological approach, a model of the Bayesian Structural Time Series (BSTS) type was developed, designed to work with time series data, and widely used for feature selection, time series forecasting, and the immediate inference of the causal impact. From the results obtained, two relevant aspects can be highlighted, firstly, both demand and its growth trend will recover very soon (in just a couple of years), compared to the pre-pandemic year 2019, which was analyzed in the case study. And, secondly, the model presents very acceptable MAPE values (between 1% and 7%, depending on the variable to be forecasted), which makes the BSTS method a viable alternative methodology for calculating air traffic forecasts.
