Here is a simple chart that illustrates succinctly why low-speed, low traffic neighborhood streets make excellent greenways for people of all ages and abilities to walk or roll through their neighborhoods:

Killing Speed and Saving Lives – Speed of car decides your chances of death

How does driver speed relate to pedestrian-motorist collisions?    “Nationally, there are over 5,000 pedestrian fatalities and about 64,000 injuries every year. These fatalities occur in urban, suburban, and rural areas and affect people of all age, race/ethnicity, and physical ability. There are a number of contributing factors to each pedestrian collision, but one of the most important issues related to pedestrian injuries and deaths is driver speed.” Source: Federal Highway Administration

Recent studies have shown that narrow streets slow traffic and reduce vehicular crashes, increasing neighborhood safety.  This is just one more reason why our neighborhood streets – the streets that are already there – are safe places for people young and old to get around by walking or biking.

There are thousands of research reports on all aspects of safe, healthy, equitable, and cost-effective streets for all. Here are just a few recent articles:

Bike infrastructure creates safer streets for everyone. Crashes for all road users (drivers, pedestrians and bicyclists) on streets with green lanes drop on average by 40 percent, and sometimes as much as 50 percent, according to a memorandum from Deputy New York Mayor Howard Wolfson. This short movie explains more about the kind of bicycle infrastructure that NYC has used to improve safety for everyone. See Measuring the street for the metrics. Source: People for Bikes

Bike lanes are good for business. “…businesses on 9th Avenue, the first major green lane in the city, saw a 49 percent rise in retail sales, compared to 3 percent across Manhattan as a whole, according to research by the New York City Department of Transportation. A study of consumer patterns by Portland State University researchers, showed “shoppers who arrive by bicycle spend 24 percent more at stores per month than those who drive.” Source: People for Bikes

On cost: Protected bike lanes cost …next to nothing compared to routine roadway maintenance and expansion projects. And instead of continuing to cost the community, they boost business, grow the tax base, and save money for the people who use them. Source: Taking the Lane
