New York City Transit officials said the agency will begin testing partitions in buses to protect drivers from unruly passengers.
The move is in response to the fatal stabbing of bus driver Edwin Thomas by a passenger after an argument over not paying a fare.
It's not clear when the program will begin or how many buses will be involved.
A transit spokesman says the partitions still needed to be designed.
Bus partitions are now being used or tested in Chicago, Washington, Baltimore, and Milwaukee.
