Evaluating Health Impacts of Car Speeds
To evaluate health impacts of car speeds, should we solely measure crashes amongst drivers on a particular roadway, or,
should we look at wider implications of higher car speeds where they discourage bicycle and pedestrian use of roadways?
Consider these statistics from Michigan Fitness Foundation:
For each hour of driving per day, obesity increases 6%.
Bicycling and walking levels in the overall population fell by 66% between 1960 and 2009.
During that same time period, obesity levels rose by 156%.
One quarter of health care costs in the United States are attributable to obesity.
The health-care costs for childhood obesity-related diseases are $14 billion a year.
Communities where more people walk are safer for walkers--
drivers are more careful!
