Traffic warnings make I-95 cool
By VICKI HYMAN
Until now, I've never found cause to string together the words "North Carolina Department of Transportation" with "cool."
The state has installed its first "smart work zone" on Interstate 95 outside Fayetteville, equipping the highway with sensors to detect speed, calculate traffic conditions and relay real time information to electronic message boards and a Web site.
I'm not talking messages like "Delays Ahead" or "Expect Congestion" that you might see on I-40 around rush hour. With all due respect to the technicians who spend hours monitoring traffic conditions via live feeds from cameras posted along the highway, let me just say, "No duh."
The messages posted on I-95 can tell drivers, to the minute, how long a delay to expect. Once the delay reaches 10 minutes, the electronic message boards offer alternate route information. The state has placed the message boards far enough ahead of the backups to give drivers a way out before they actually hit the traffic.
On the Web site, http://www.I95fayetteville.com, you can even view how fast traffic is moving through the work zone.
