The Fairfax County Board of Supervisors on Tuesday approved the creation of a traffic management group in Tysons Corner geared toward getting commuters to use local buses and the Metrorail Silver Line that is scheduled to start service later this month.

The effort, to be overseen by the Tysons Partnership business group, is part of a larger attempt to convert the traffic-choked neighborhood of shopping malls and office towers into a pedestrian-friendly community with bike lanes and trails.

The area currently sees about 100,000 cars per day, a number expected to increase as more people move into new high-rise apartment buildings and office towers planned over the next few decades.

With new roads and other infrastructure improvements also planned, logistical challenges are likely for drivers trying to get in and out of the neighborhood, transportation officials said.

For example, a more narrow grid of streets planned for the neighborhood may prove to be challenging for delivery truck drivers used to navigating the broader suburban style roads that now wrap around Tysons, said Abraham Lerner, a supervisor with the Virginia Department of Transportation who is helping to coordinate traffic improvements in the area.

It would be up to local building owners to tell those drivers to use smaller trucks, Lerner said.

“That’s going to be a learning process,” he said, anticipating a small increase in traffic congestion for a few years. “We don’t anticipate it to be foolproof.”

Aaron Georgelas, a partner at the Georgelas Group, which plans to build 17 buildings in Tysons, said the new traffic management group will analyze ways to reduce congestion in the area. A 25-story apartment complex being co-developed by Georgelas is nearing completion.

The transportation group plans to develop a Web site for commuters that will post options for van pools, car pools and ride-share programs, Georgelas said.

“We’re going to become the nucleus of helping people manage their commutes in and out,” said Georgelas, a board member at Tysons Partnership.

The group will operate with about $65,000 per year expected to be raised by developers, according to county documents.
