Will 'Talking' Cars Lead to Fewer Collisions? | CNBC

My opinion: this big data / data science technology - to track your vehicle movements to alert you of an imminent crash or to tell you that you drive too fast -  will create many false positives resulting in more collisions for a number of drivers (maybe for 10% of all drivers who outperform automated driving). But it can really help dumb drivers. So,…

Obama Administration Unveils $200M Big Data R&D Initiative

Throughout the 2008 hurricane season, the Texas Advanced Computing Center was an active participant in a NOAA research effort to develop next-generation hurricane models. Teams of scientists relied on TACC's Ranger supercomputer to test high-resolution ensemble hurricane models, and to track evacuation routes from data streams on the ground and from space. Using up to 40,000 processing cores at once, researchers simulated both global and regional weather models and received on-demand access to some of the most powerful hardware in the world enabling real-time, high-resolution ensemble simulations of the storm. This visualization of Hurricane Ike shows the storm developing in the gulf and making landfall on the Texas coast [image courtesy Gregory P. Johnson, Romy Schneider, John Cazes, Karl Schulz, Bill Barth, The University of Texas at Austin; Frank Marks, NOAA; Fuqing Zheng, University of Pennsylvania; Yonghui Weng, Texas A&M; via NSF].
