The RADar! reporting platform is a web-based planning and citizen participation tool by Climate Alliance. RADar! offers municipalities and their inhabitants optimal opportunities to further promote cycling in their municipality together.

Cyclists draw municipal authorities’ attention to problematic and/or dangerous places along cycle routes via the RADar! app or online: they simply position a pin on the street map and provide a brief explanation of the reason for their report. This is automatically forwarded to the responsible municipality, which can then take the appropriate action.

Good Example

"Thanks to RADar!, administrative staff have an ideal opportunity to use the knowledge and experience of our residents in everyday cycling. Through the direct feedback we can now effectively improve cycling infrastructure and inform our fellow residents about the current status of our efforts online in an uncomplicated and transparent manner."

Katrin Eder, Head of Department for Environment, Green, Energy and Transport of the State Capital Mainz
