HAND-HELD COMPUTERS MAY REDUCE AIRPORT CONGESTION

NASA researchers have determined that small, Internet-linked computers in the hands of airport workers may help unclog the nation's air terminals.

The research finding is based on studies at San Francisco International Airport and other air terminals. NASA scientists at Ames Research Center, in California's Silicon Valley, collaborated with United Airlines on the two-year project. Researchers also suggest that additional "curb-to-gate" changes, including better signs in terminals, synchronized clocks and improved check-in procedures, as well as improvements in airline and airport operations, may help reduce flight delays.

"The study recommends the development of a next generation of airport information systems. These would include use of hand-held computers to allow airline employees and others to update schedules on the tarmac, on baggage carts and in gate areas," according to Roxana Wales, Ph.D., a member of the Ames research team. "Delays can arise at any point in a flight, including preparations before leaving the gate; and difficulties at one point can lead to a slipped schedule at any other point. We have to focus on the entire system. Much of the current attention focuses on the movement of planes instead of the whole process of getting people from point A to point B," she said.

Other experts across the country have advocated adding runways to airports and are working to improve air traffic control systems. "Airline and airport operations need to be included in the debate on how to streamline the nation's air travel system," said Wales.

"United Airlines gave us access to all areas of their operation. They badged us for access to non-public areas and allowed us to interact and talk with employees at all levels. This is extraordinary access for a group of researchers," she explained. The team conducted extensive research in airline operation centers, on baggage ramps where airplanes are loaded and unloaded, in airline lobbies, at counters, at passenger gates and in control towers.

Today's airport information and communication systems are designed for routine aircraft turnaround, according to the NASA research team. Problem and delay situations "require a 'richer' information environment to facilitate decision-making," Wales said.

The good news is that there are near-term solutions in sight that include simply integrating information systems across groups in airports, according to the NASA researchers. They also said that better communications and other improvements should include not only airline employees, but all workers involved in smoothly getting a passenger from the street to his or her destination.

"A breakdown in the process, where the customer is unable to understand and expediently move through one step to another, at any point, can contribute to a delay," said Zara Mirmalek, research team member. The team conducted research at San Francisco's United domestic terminal and airports serving Atlanta, Chicago and Oakland, Calif.
