While nationwide traffic deaths increased 1.4%, they increased much more significantly for pedestrians and bicyclists according to this article from the Detroit News:
Pedestrian deaths represented more than 10 percent of all traffic deaths and increased 4.4 percent in 2005 to 4,881, while deaths among bicyclists increased 8 percent to 784.
The NHTSA is concerned about the spike in pedestrian deaths and is investigating it, said Tyson, the spokesman. But the agency has no plans to mandate any safety improvements geared toward protecting pedestrians. “One year does not a trend make,” Tyson said.
