Análisis De Deslizamientos En La Ciudad Capital Utilizando Sistemas De Información Geográfica, Pedro Pablo Conlledo, Ronaldo Luna
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
En Guatemala, los daños ocasionados por deslizamientos de tierra son innumerables, y sin embargos son pocos los esfuezos que se han hecho a nivel nacional por estudiarlos. El principal objetivo de este trabajo fue utilizar Sistemas de lnformacion Geografica (SlG) para estudiar sistematicamente la ocurrencia de deslizamientos en el Departamento de Guatemala con la informacion disponible.

Visual Traffic Movement Counts At Intersection For Origin-Destination (O-D) Trip Table Estimation, S. Lee, Hojong Baik, J. Park

Origin-destination (O-D) trip table is necessary information for transportation planning and traffic impact study. However, current O-D estimations rely on estimated directional traffic counts at intersections, which obviously diminish reliability in the table. A video-based vehicle tracking system that utilizes wide view-angle lenses has been studied [26] to provide accurate direction traffic counts. The system expands the area covered by a single camera and uses a particle filtering method to handle environmental changes as well as geometric distortion caused by those lenses. This paper shows tracking capability of the system and also shows how to incorporate the directional traffic counts …
