This new metric assesses road safety before any accidents ever happen

The way urban planners currently assess the safety of a road involves counting the number of accidents on that particular road. Essentially, this means that there’s a "literal human cost" to measuring how safe a street is, says Megan Ryerson, a transportation engineer and urban planner at the Read More...
