Pedestrian Safety at Roundabouts: Melbourne, Australia data tells us that modern roundabouts tend to be much safer than traffic signals for pedestrian safety. Pedestrian safety is perhaps the most important benchmark for a transportation system.

Melbourne Data:
Pedestrians at all signalized intersections (about 2,500) in the Melbourne Metro area for 2002-2006:
* Fatal: 27
* Serious Injury (hospital): 614
* Other (medical): 701

Pedestrians at roundabouts (over 4,000) in the Melbourne Metro area for 1996-2000
* Fatal: 0
* Serious Injury (hospital): 18
* Other (medical): 39

While other variables need to be considered- such as total number of pedestrians and cars using the intersections- these statistics still illuminate the immense safety benefits of modern roundabouts.
