PROJECT TITLE :

Visualization, Selection, and Analysis of Traffic Flows

ABSTRACT:

Visualization of the trajectories of moving objects results in dense and cluttered images, that hinders exploration and understanding. It also hinders adding extra visual info, such as direction, and makes it difficult to interactively extract traffic flows, i.e., subsets of trajectories. During this paper we tend to gift our approach to visualize traffic flows and provide interaction tools to support their exploration. We have a tendency to show an summary of the traffic using a density map. The directions of traffic flows are visualized employing a particle system on top of the density map. The user can extract traffic flows employing a novel selection widget that enables for the intuitive selection of an area, and filtering on a vary of directions and any extra attributes. Using simple, visual set expressions, the user will construct a lot of sophisticated selections. The dynamic behaviors of selected flows could then be shown in annotation windows in that they'll be interactively explored and compared. We validate our approach through use cases where we have a tendency to explore and analyze the temporal behavior of aircraft and vessel trajectories, e.g., landing and takeoff sequences, or the evolution of flight route density. The aircraft use cases have been developed and validated in collaboration with domain specialists.
