CB-SMoT+: Una Extensión al Algoritmo CB-SMoT

Abstract

Una trayectoria es un registro de la evolución de la posición de un objeto móvil. Por ejemplo, un vehículo que se mueve en el espacio durante un intervalo de tiempo. Una trayectoria se representa mediante una secuencia de observaciones que indican la posición y el tiempo en el que fue tomada cada observación. CB-SMoT es un algoritmo que identifica las partes de una trayectoria durante las cuales el objeto mantuvo una velocidad promedio por debajo de un límite dado. En este artículo se propone una extensión para dicho algoritmo que permite identificar las partes de una trayectoria durante las cuales el objeto mantuvo una velocidad promedio entre observaciones por debajo de un límite dado. Esto posibilita la identificación, por ejemplo, de violaciones a un límite de velocidad que no son advertidas por el algoritmo original. Para el estudio se usó el sistema de gestión de bases de datos PostgreSQL y los algoritmos se implementaron en su lenguaje de programación, llamado PL/pgSQL. Además, se hicieron experimentos con 100 trayectorias de vehículos con el propósito de mostrar la utilidad y la viabilidad de la propuesta
