Análisis de la modelación de la distribución de viajes para diferentes categorías socioeconómicas en el Valle de Aburrá/Analysis of trip distribution modeling for different socio-economic categories at the Valle de Aburrá

This article is about the analysis of trip distribution modeling for different socioeconomic categories at the Metropolitan Area of the Valle de Aburra for the year 2005. The gravity model was applied using the software TransCAD. This model determines the trips between two zones in accordance with the generation and attraction of trips between related zones and an impedance function that depends on the travel time-cost between zones. The model was analyzed for different AM and PM peak hour periods and for different purposes: study, work and other, finding that the negative exponential is the impedance function, which adapts best to the models for the different socioeconomic categories.
