WOODBRIDGE, N.J. - New Jersey's frazzled drivers are getting some help.

Besides showing off a new $29 million traffic-management center designed to keep traffic moving, state officials yesterday unveiled a new Web site and telephone system to help commuters navigate the Garden State's jammed roads and save money on ever-pricier gas.

"This is a terrific step forward," Gov. Jon S. Corzine said as he toured the new traffic center.

A recent Rutgers University study found that New Jersey's highways are the nation's most congested and its residents have the third-longest commutes in the nation.

The services designed to ease such woes include:

* A new Web site, www.NJ511.info, which offers maps and displays traffic incidents to give motorists real-time traffic conditions on state highways, interstate highways, the Garden State Parkway and the New Jersey Turnpike. The site highlights incidents, construction, weather and special events and includes traffic cameras.

* A 511 telephone number that provides information on traffic, weather and construction. Users can request updated information on highways and geographic areas.

* And, starting this summer, a personalized traveler service that will send real-time road updates and alerts to motorists' cell phones and e-mails. The free service will allow motorists to sign up to receive alerts about traffic and construction affecting their daily commutes.

The new $29 million traffic center is located between the Turnpike and Parkway.

The 26,000-square-foot complex features a video wall that's 18 feet long by 50 feet wide, enabling real-time displays of highways throughout the state from 420 traffic cameras.

State officials hope the center will help provide better information to motorists and improve responses to crashes, snowstorms and other traffic nightmares.

"We can't build our way our of the congestion problem," Transportation Commissioner Kris Kolluri said. "What we have to do is put technology tools in place." *
