A Bike Bell That Maps Where Cyclists Feel Unsafe and Pings the Mayor

London cyclists who encounter stressful, dangerous conditions can crowdsource a map of weaknesses in the city's bike network by simply tapping a button on their handlebars. Brandon G. Donnelly at Architect This City has more:

Every time the button is hit, the data point gets logged to a public map and an email gets sent to the Mayor of London reminding him of his promises around cycling. Both of these things happen via the rider’s smartphone.

Not only does it tell you pain point locations, but it also seems to suggest the primary cycling routes. I think this is a brilliant initiative because, it’s entirely user-centric. It’s telling you how people feel on the ground.

It will be interesting to see if the feedback from the bells can be channeled productively. Is there enough detail in that map to be useful to bike planners?
