A Before-and-After Guide to Safer Streets

In the past decade or so, New York has seen a considerable decline in traffic fatalities (30 percent since 2001) and an even more dramatic decrease in the risk of serious injury among cyclists (72 percent since 2000). At the heart of these public safety achievements is better street design. City streets are far from perfect, but as officials have reduced space for cars, they've improved mobility for everyone.

Last month, the New York City Department of Transportation released a brief-but-handy guide [PDF] that uses before-and-after design renderings to illustrate five basic rules for street safety. The report calls its comparisons "the largest examination of the safety effects of innovative roadway engineering conducted in a major American city, or perhaps any city globally." That's a tall claim, but there's no question that the five lessons embedded in these images merit notice from urban communities near and far.
