Abstract

Resumen: Las percepciones de seguridad y comodidad relacionadas con viajar en bus o en avión pueden afectar las decisiones de elección de los pasajeros en viajes domésticos. En este artículo se incorporaron las variables latentes seguridad y comodidad dentro de los modelos econométricos para estudiar la elección del modo de transporte para pasajeros que viajan en el trayecto Medellín-Barranquilla. En el modelo calibrado se incluyeron variables asociadas al modo de transporte, como el costo, el tiempo de viaje y las frecuencias, además de las variables de percepción. El modelo de elección discreta con variables latentes (VLs) se estimó secuencialmente: en primer lugar, se obtuvieron los parámetros del modelo de múltiples indicadores múltiples causas (MIMIC) y —posteriormente— se calibró el modelo híbrido de elección. El modelo calibrado permitió identificar las variables que inciden en la elección del modo de transporte aéreo o terrestre. Los resultados obtenidos son una herramienta eficaz en la toma de decisiones para las empresas que operan en cada uno de los modos. Abstract: Safety and comfort perceptions related to travel by bus or plane could affect passenger choice behavior in domestic trips. In this research, the safety and comfort latent variables were incorporated into the econometric models to study the choice of transportation mode for passengers who travel along the Medellin - Barranquilla route. Variables associated with the transportation mode such as cost, travel time, and frequency were included in the calibrated model and perceptional variables. The discrete choice model with latent variables (LVs) found in this research was sequentially estimated. Firstly, the parameters of Multiple Indicators Multiple Causes Model (MIMIC) were found, and then the hybrid choice model was calibrated. The calibrated model allowed us to identify the variables that affect the decision-making process for air and land transportation mode choice. The results are an effective decision-making tool for companies that operate in each of the transportation modes.
