NTSB: Speed Kills, and We’re Not Doing Enough to Stop It

| | 5 Comments
More than 112,500 people lost their lives in speed-related crashes from 2005 to 2014, accounting for 31 percent of all traffic deaths in America over that period. In a draft report released earlier this week, the National Transportation Safety Board says excessive speed is a deadly problem in our nation's transportation system -- one that federal and state officials aren't doing enough to address.

What Do Drivers Really Think of Cyclists?

There's ample research out there backing up the safety benefits of streets with protected bikeways and slow car speeds. But what about the critically important yet less tangible factor of individual attitudes -- how does the mind of the person behind the wheel affect driver behavior toward cyclists? A new report from Portland State University looks at the question.

Can Algorithms Design Safer Intersections?

| | 5 Comments
Cities and tech firms are deploying new technology to gauge risks at dangerous intersections. These sensors, cameras, and machine-learning algorithms are promising, especially when it comes to measuring close calls that don't result in crashes - but cities are still figuring out how they can use this information. In the meantime, there's no reason to wait on designing safe streets.
