This effort is spearheaded by the Metropolitan Transportation Authority (MTA), together with NJ TRANSIT, Port Authority of New York and New Jersey, Amtrak, NYC Ferry, and other regional bus and ferry operators.
At 3:00 p.m. (EST) tomorrow, all participating transit organizations are asked to simultaneously sound two one-second horn blasts from each vehicle in service.
