MTA uses Google Pixel smartphones and AI to detect subway track defects
The subway in NYC has received a huge upgrade, but it’s probably not at all what you’d expect. No, it is not coming in the form of new trains or renovations to stations (even though that would be great). Actually, the MTA is testing a system that effectively transforms Google Pixel Android smartphones into powerful diagnostic tools for tracking rail defects!
The project, called “TrackInspect,” attaches Google Pixel phones to subway cars. Then, by using the Android devices’ built-in microphones and motion sensors, it detects vibrations and sound patterns. These sounds can indicate areas of track that may need maintenance. How cool is that?
