Speeding increases energy in a crash exponentially

A car moving at 70 miles per hour has to stop suddenly. Another car going 100 miles per hour also has to stop suddenly. Your intuition might say that the former requires 30% less energy to stop, but the energy required is actually proportional to the square of the velocity. Ben Sparks for Numberphile explains: Okay. Now what are the energy gains and losses for the guy trying to speed...

For years, there have been fewer deaths than the year before, but the 2015 data shows a 7.2 percent increase. So, the NHTSA released the data earlier this year and, along with the White House, formally reached out to the data...

Google, I think currently only on Android phones, now provides information on when people go to the businesses around you, using a similar logic to auto traffic on Google Maps. Nice.

Traffic gridlock simulation

I hate all things commute- and traffic-related, and it's probably why I like to learn about what makes commutes painful. Maybe if I know more about what's happening, I won't get so frustrated when I have to drive. Transportation engineering PhD candidate Lewis Lehe has a look at bottlenecks and gridlock, creating simulations of both. The former is when too many cars want to do the same thing at once,...
