Abstract
El tránsito de vehículos pesados (especialmente si sobrepasan el tonelaje permitido) es uno de los factores de mayor significancia en el deterioro de la infraestructura vial de Costa Rica, pues disminuye considerablemente la vida útil de los pavimentos; de ahí la importancia de un adecuado control de los tonelajes de mercancías con los cuales circulan. Por lo tanto, debido a las disposiciones de acatamiento obligatorio impuestas por la Contraloría General de la República al CONAVI, en el Informe DFOE-IFR-1F-07-2013 con respecto a las estaciones de pesaje; el CONAVI solicita formalmente la colaboración en forma de Asesoría Técnica por parte del LanammeUCR, mediante el oficio DSUR-01-03-009, para que elabore un estudio técnico en el que se den recomendaciones de los principales sitios en los cuales son necesarias estaciones de pesaje en las carreteras de la Red Vial Nacional de Costa Rica, que permitan regular el peso de los vehículos pesados. Para cumplir con este objetivo, se genera una matriz de distribución de viajes que muestre el flujo de toneladas métricas de productos agropecuarios y de construcción anual por las principales carreteras del país; y con base en esto y otras características de relevancia, se determina una recomendación para la ubicación de las estaciones de pesaje. De los resultados obtenidos, se deduce que las principales rutas en el tránsito de toneladas métricas son la 1, Z 27 y 32, con un aproximado de entre dos y 4.5 millones de toneladas métricas anuales. Del análisis de los datos, se obtiene como resultado final que es necesario un total de 13 estaciones de pesaje para controlar el peso de los vehículos de carga que transitan a nivel nacional. Sin embargo, de las estaciones propuestas, ya cuatro de ellas están en funcionamiento actualmente (Mofa, Ochomogo, Esparza y Cañas). Además, se recomienda elaborar encuestas Origen-Destino de vehículos de carga y conteos con clasificación de vehículos pesados, para validar los datos aquí descritos.
The transit of heavy vehicles (especially the ones that exceed the allowed weight) is one of the most significant factors in the deterioration of the road infrastructure of Costa Rica, since it considerably reduces the useful life of the pavements. It’s important to control the weight of the goods with which they circulate. Due to the compulsory compliance provisions imposed by the Office of the Comptroller General of the Republic to CONAVI, in the DFOE-IFR-1F-07-2013 Report with respect to the weighing stations; CONAVI formally requests collaboration in the form of technical advice from the LanammeUCR, through the official letter DSUR-01-03-009, so that it can prepare a technical study that gives recommendations of the main sites in which stations are needed. To achieve this objective, a travel distribution matrix is generated: it shows the flow of metric tons of agricultural products and annual construction by the main roads of the country; and based on this and other relevant characteristics, a recommendation for the location of the weighing stations is determined. From the results obtained, it is deduced that the main routes in the transit of metric tons are route 1, Z 27 and 32, with an approximate of between two and 4.5 million metric tons per year. From the analysis of the data, it is obtained as a final result that a total of 13 weighing stations are necessary to control the weight of the freight vehicles that transit nationally. However, of the proposed stations, four of them are currently in operation (Mofa, Ochomogo, Esparza and Cañas). It is recommended to prepare Source-Destination surveys of cargo vehicles and counts with heavy vehicle classification to validate the data described here.
