ALBANY, N.Y. (AP) _ Radar, flashy LED signs, and text alerts to drivers' cell phones and local police are part of New York's new, high-tech effort to combat often fatal wrong-way crashes on the state Thruway.

Gov. Andrew Cuomo says the system linked to Doppler radar and designed by state Thruway Authority workers is being installed at the Thruway's Buffalo exit at the Niagara Expressway, also identified as Interstate 190.

The second stage will be installed in Rockland County's Nyack, the site of several serious wrong-way crashes. More exits will soon get the systems along the 570-mile interstate highway.

Cuomo says Wednesday the system is the first like it in the nation.

State Police Superintendent Joseph D'Amico calls it a cutting-edge advancement.
