The population in the Triangle is constantly growing and changing, so the TTA must try to predict that growth when considering ridership.
Schulz said the rail system will provide opportunities for economic development as areas around the stations grow into larger communities.
"More and more people, young professionals and retirees, don't want to live far out," he said. "It's becoming more and more important for people to live close to where they work."
The retiring age group is of particular interest to transportation issues. As people get older they will be less inclined, or able, to drive.
"A larger group of aging drivers is coming soon within the next few years," said Joseph Hummer, a civil engineering professor at N.C. State University. "The first of the baby boomers turn 60 next year, and some time in the 60s eyesight, for one, starts to decline."
He said it is important to have transportation alternatives for these people.
Connecting campuses
Once in place, the rail system would allow students to travel to neighboring schools for academic and social purposes.
Hummer said he thinks there are many students who would welcome the opportunity to be more connected with other schools.
"In our program we have students that would like to take classes in Chapel Hill and can't because of the commutes and parking," he said. "I believe there are students who would like to take classes on our campus but don't because of the length of the commute, and a lot of students don't have access to a car.
"That could help interaction between the campuses."
Schulz said the rail system also would allow students opportunities to interact with other campuses outside of academics.

"It's not just for academics, but for having fun," he said, adding that students could use the system in place of a designated driver for late nights at other schools. Schulz said there will be a station placed in the middle of the N.C. State, N.C. Central University and Duke University campuses.
Existing options
Connecting campuses and providing a safe alternative to students who need to get home after a night at the bars is not a new concept to the Triangle's university communities.
The Robertson Scholars Program has a bus running between UNC-Chapel Hill and Duke University until midnight on the weekends.
Chapel Hill Transit provides its own Safe Ride option for residents Thursday through Saturday nights.
"Safe Ride was introduced because of requests through UNC to give a late night safe ride home after the bars closed," said Jeff Freer, administrative analyst for the town of Chapel Hill's department of transportation. He said it was designed to discourage drunken driving.
Between 210 and 355 people used the Safe Ride buses each weekend during the first three weeks of service.
The Robertson Scholars bus and Safe Ride in Chapel Hill plan to continue operating even after the rail system is in place as long as there is interest in the services.
