The typical image people have of air traffic control (ATC) is that of a group of people in an airport tower who coordinate aircraft activity by staring at radar screens that use points of light to represent aircraft. While not fundamentally incorrect, this isn't a fair representation of the extent of ATC operations. This article will flesh out that simplistic image and introduce you to the equipment, technologies, and procedures that go into keeping aircraft and air travelers safe in the air and on the ground. We'll look at the way air traffic control is organized, and explore the communication technologies that air traffic controllers use to keep in touch with air crew and ground personnel. We'll also look at the radar technologies used to keep track of aircraft, and we'll end with a brief look at some next-generation technologies.

University of Washington Traffic Light Model with Immediate Ambulance Handling

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol. Hundreds of thousands of people around the world use Tor for a wide variety of reasons: journalists and bloggers, human rights workers, law enforcement officers, soldiers, corporations, citizens of repressive regimes, and just ordinary citizens. (Note: sometimes ITGS students need to be able to access sites that are sometimes blocked)

Outstanding show, explains a lot about worms vs viruses as well as botnets. It's an interview with the author so it also illustrates how to ask good questions. (useful for the project) The gigantic networked system created by the Conficker worm is what's known as a "botnet." The Conficker botnet is powerful enough to take over computer networks that control banking, telephones, security systems, air traffic control and even the Internet itself, says Bowden. His new book, Worm: The First Digital World War, details how Conficker was discovered, how it works, and the ongoing programming battle to bring down the Conficker worm, which he says could have widespread consequences if used nefariously.

Could raise interesting questions in many fields - military, traffic, advances in automobiles etc.
