Helping out is easy

Are you sick of bike lanes blocked by cars, shuttles buses and delivery vans? Help gather action-able, verifiable data on how frequently Arlington's bike lanes are blocked so we can make a strong case to the police for pro-active enforcement.

All you need to do is look at a photo of a block that has a bike lane and tell us it appears to be blocked or not.

You can do it from your phone, from your iPad or from your PC. Whether you can do 100 or just 1, every little bit helps. Do it while you wait for the bus, while drinking a beer on your patio or as penance anytime you fail to be a PAL. Let's get a solid answer to the question - Just how frequently are Arlington's bike lanes blocked?

Let's see some bike lanes!

How Does it Work?

The system consists of two pieces. The first is an application that saves a screenshot of various Arlington County Traffic Cameras every minute along with the date and time that it was saved. The second is this website, which displays those screenshots to users of the site and records whether the bike lane is blocked.

The site treats each screenshot as "unsure" until at least two different people agree that the lane is either blocked or unblocked. If people disagree, the system continues to show it to new users until there is a majority who agree.
