The app is the latest attempt by Beijing, which has tried several means to address the traffic congestion termed by many as the city's most serious "urban disease."
Beijing Insurance Regulatory Commission today said that 172 traffic accidents were resolved through the trial version of the app, which was put in use on May 13 in some areas of the city's Haidian and Changping districts.
When a minor traffic accident occurs, users post pictures of the scene via the mobile app, and traffic police can determine responsibility and damage online.
The app is suitable for accidents in which vehicles are slightly damaged and passengers sustain only minor injuries.
