Portland paid $200,000 to paint little green bike boxes at a few intersections to curb bike/car accidents. When this idea came up – a great number of voices lauded it. Well, after an actual independent study – it’s proven they don’t do much either way – mostly because there were statistically so few accidents to begin with involving intersections such as these. Maybe it helps raise awareness of bikers by putting them in front of you? Don’t know, but glad someone is actually studying the effectiveness of these efforts.
