Olympic transportation control system tested

Greek authorities ran an Olympic transportation safety drill this week, testing an electronic network of more than 1,000 security cameras, sensors and devices to control traffic lanes for buses carrying athletes.

Code-named “Olympic Hermes,” the drill was held at key points in Athens, involving operations by air and ground police to monitor public transit and respond to accidents and other problems.

The $300 million electronic web, which connects to a central command center, is a major part of the Olympics’ $1.5 billion security budget.

Officials said the security system is operational, and security forces are ready for the Aug. 13-29 games.
