The Boston Bike Crash Map

Thousands of bicyclists ride to work in Boston every day. Across bridges and into traffic, through quiet streets and busy intersections, commuting by bike is getting more popular each week. But is it safe?

A bike advocacy group called the Boston Cyclists Union has uploaded an interactive map showing all of the city's reported bicycle crashes in recent months. Among other concentrations, it shows a dark line of bruised elbows, broken fenders, and worse stretching from the Back Bay to Allston along Commonwealth Avenue, right past our studios at WBUR.

Radio Boston's Adam Ragusea examines what the Interactive Crash Map shows about biking in Boston.
