Increasing bicycle use in Seattle may depend on how well the city can address the danger of the "right hook" -- right turns at intersections that cause many of the city's bicycle accidents and fatalities.
"'Right-hook' collisions, as riders call them, are among the most common risks of urban cycling. A bike enters an intersection going straight and gets hit by a right-turning car."
"It's a problem that cities such as Seattle must solve as they encourage thousands of people to switch from cars to bicycles. Mayor Greg Nickels has set a goal of tripling bicycle use within a decade."
"Currently, the city estimates that 4,000 to 8,000 people cycle to work or school each weekday, depending on the weather, and 36 percent of residents ride for fun, errands or a commute at least occasionally."
"The city's new Bicycle Master Plan calls for expanding the bike-lane network, now 31 miles, to 143 miles by 2016, and extending the trail system from 39 miles to 58 miles. To address right-hook crashes, Seattle this spring will attempt to make bike lanes at a few busy intersections more noticeable by painting them green, a strategy already tried by other cities."
