Reporting safety and security concerns with a few clicks – indeed there’s an app for that in Los Angeles, where passengers on the Metro can file a report or reach security with just a few taps through the LA Metro Transit Watch app.

A spokesperson for the Los Angeles County Metropolitan Transportation Authority called the app their way of directly connecting with passengers 24/7. Passengers contact Metro Security by text message or phone call and can remain anonymous – and they even use the app to submit photos of concerns on trains, buses, platforms, or stops.

Passengers can also get push notifications with critical alerts from LA Metro, and there is Spanish-language support.

In Miami, passengers are using the Go Miami-Dade Transit app. A spokesperson said incidents reported on the app go directly to security dispatchers monitoring it 24/7. They can send the right first responders that way, and chat with passengers in real time.
