The Taxi and Limousine Commission this week issued a request for information on "anti-speeding vehicle technologies," reports The New York Times.
The measures include devices that can intervene when drivers exceed posted speeds and "advisory systems" that can sound alarms when reckless driving is detected.
The TLC says anti-speeding devices could be tested on a pilot basis but would not necessarily result in any contracts.
Its request comes weeks after the city said it was seeking information on "black box" devices that could record cabbie's behavior. It's part of Mayor de Blasio's "Vision Zero" plan aimed at eliminating traffic deaths.
