Travel time contour map

This travel time contour map gives a representation of the minimum time required to reach a location in a transportation network from selected origins. By analyzing travel time contours and their variation during the day, transportation planners are able to assess the impact of congestion on the connectivity of selected areas. The map is generated by processing the spatio-temporal trajectory of thousands of vehicles, as produced by an advanced transportation planning model.

The Capital Area Metropolitan Planning Organization (CAMPO) is the federally mandated metropolitan planning organization (MPO) responsible for comprehensive transportation planning in the Austin, Texas, area.

The data being visualized comes from the Center for Transportation Research at the University of Texas (UT) at Austin. The visualization application was developed at the Texas Advanced Computing Center (TACC) at UT-Austin and the visualization itself was generated there. TACC is part of the National Science Foundation's Extreme Science and Engineering Discovery Environment (XSEDE), the foundation's investment in an integrated, advanced cyberinfrastructure that will empower America's scientists and engineers to interactively share advanced computational resources, data and expertise in order to further research across scientific disciplines.
