ICT in the Local CommunityAirportsIn airports, all public access is channelled by the terminal,where every person must walk through a metal detector and all itemsmust go through an X-ray machine which therefore sends the picture to amonitor where a person can see what luggage you are carrying and ifyou are concealing any metal objects that may coiffe a threat to otherpassengers. All of the checked luggage goes through a large X-raymachine before it is loaded onto the aircraft. In the linked States,most major airports have a computer tomography (CT) scanner. A CTscanner is a hollow tube that surrounds your bag. The X-ray mechanismrevolves late around it, bombarding it with X-rays and recording theresulting data. The CT scanner uses all of this data to create a verydetailed tomogram (slice) of the bag. The scanner is able to calculatethe mass and tightness of individual objects in your bag based on thistomogram. If an objects mass/density falls within the range of adangerous mater ial, the CT scanner warns the operator of a potentialhazardous object.CT scanners are slow compared to other types of baggage-scanning forms. Because of this, they are not used to check every bag.Instead, only bags that the computer flags as suspicious arechecked. These flags are triggered by any anomaly that shows up in thereservation or check-in process. For example, if a person buys aone-way ticket and pays cash, this is considered atypical and couldcause the computer to flag that person. When this happens, thatpersons checked bags are immediately sent through the CT scanner,which is usually located somewhere in effect(p) the ticketing counter.A baggage-handling system makes all of the decisions about where a bagis going. Hundreds of computers keep track of the location of everybag, every travellers itinerary and the schedules of all the planes.Computers control the car transporter junctions and switches in the DCVtracks to make sure each bag ends up exactly where it needs to go. Theprocess begins when you check in and hand your bag to the actor.When you check in, the agent pulls up your itinerary on the computerand prints out one or more tags to attach to each of your pieces ofluggage. The tag has all of your flight information on it, includingyour destination and any stopover cities, as well as a bar code thatcontains a ten-digit number.This number is unique to your luggage. All of the computers in thebaggage-handling system can use this number to look up your itinerary.
