So, lets forget where the quote came from. Let's just look at a specific study done by the State of Orgeon.

The study looked at 12 different areas in Oregon (Portland I guess?) where streets were converted from 2 way streets into 1 way couplets. Data was collected for several years before and after the conversion.

All collisions before = 4755 All collisions after = 4295

pedestrian collisions before = 156 Pedestrian collisions after = 122

Someone questioned the rate of accidents. Although there is no data regarding accidents per number of pedestrians, there is data for accidents per million vehicle miles.

Accidents per MVM before = 41.27 Accidents per MVM after = 30.21

Accident rates decreased in 11 of the 12 areas studied.

The accident severity rate was shown to, on average, stay the same or reduce slightly after conversion to one way couplet.

Based on the above, I don't know how anyone can conclusively say that two way streets are, without question, safer than one way streets... even for pedestrians.
