These approaches—in addition to filling a data gap for many agencies and helping them target high risk locations—could lead many road designers to look more closely at the role of speed and speed management in highway safety.

Drivers more likely to ignore crosswalks at speeds above 30 mph
According to a new study published by the Transportation Research Board, drivers traveling at higher speeds are also far less likely to yield to pedestrians in crosswalks. The study, conducted in Boston, reveals that drivers are nearly four times more likely to yield for pedestrians at travel speeds around 20 miles per hour than at 40 mph.
One-way or two-way streets more efficient? It depends on what you measure
The debate over one-way versus two-way streets has been ongoing for more than half a century in American cities. Counter to prevailing engineering wisdom, a new study finds two-way streets may be more efficient, if one is measuring getting people to their destinations.
