Were you almost hit by a speeding cab on 34th Street? Did you spy some scofflaw jaywalking? Are you a self-loathing cop who would like to turn him or herself in for parking in the bike lane? There's a map for that!

As part of the city's campaign to eliminate traffic deaths, the DOT yesterday unveiled its new Vision Zero interactive map, which allows users to mark the exact spot at which they were almost plowed over by a Citi Biker too busy coordinating his life-sized child accessory with his cable knit sweater to watch the road. A dot will appear at the location of your brush with death/minor irritation; its color correlated to the offense at hand: Purple is speeding, green is double parking, yellow is failure to yield and light blue is something called "cyclist behavior."

DOT explains the map thusly:

Every year, approximately 4,000 New Yorkers are seriously injured and more than 250 are killed in traffic crashes. Being struck by a vehicle is the leading cause of injury-related death for children under 14, and the second leading cause for seniors. On average, vehicles seriously injure or kill a New Yorker every two hours.

Vision Zero is the City's goal for ending traffic deaths and injuries on our streets. To accomplish this, we need everyone's participation and input. Learn more about Vision Zero.

Use this interactive map to share your experiences with city streets. Your knowledge will be used to create a traffic safety plan for each borough that will describe how to make each borough’s streets safer for everyone, whether walking, biking or driving.

Already the map is surfeit with dots, looking from a distance like the the work of an unsupervised toddler with access to unlimited sprinkles. And it's only been live for 24-hours! Will the map really be able to accommodate the tidal wave of complaints it will undoubtedly receive, or will the dots eventually start stacking on top of each other, overwhelming the system? Let's find out!

And remember: The map isn't the only answer. Vision Zero public workshops are currently being held in a neighborhood near you.
