Method and System for Providing Cloud-based, Crowd-Sourced Smartphone Speed Limit Detector

Speed limits in global positioning system (GPS) rely on data from F.H.A., Stack Exchange, D.O.T. National transportation library, and TFHRC (Turner Fairbank Highway Research Center). The data is often out of date (only 44% to 50% accurate by one estimate) and the problem is compounded by the use of electronic (dynamic) speed limit signs that change according to traffic congestion and by construction zones that takes down reduced speed limit signs following the vagaries of local highway departments. Disclosed is a method and system for providing cloud-based, crowd-sourced smartphone speed limit detector. The method and system provides technology-driven, crowdsourcing channel for dynamically providing speed limit updates to the existing databases (DB). In accordance with the method and system, user (vehicle driver) is allowed to suction- cup the smartphone to the vehicle windshield, with camera of the smartphone facing forward (like a dash cam) to capture/record speed-limit signs on the road. An image/video capturing application (app) of the smartphone then captures/records speed limit signs and directly uploads to a crowd-sourced cloud DB. The app also provides over limit alerts to the vehicle driver, possibly in coordination with GPS application of the smartphone. The crowd-sourced cloud DB can also be shared with various GPS devices for timely updates to speed limits (e.g., constructi...
