Travel is the movement of humans between different geographical locations. Travel can usually be done with or without luggage, by foot, bike, car, train, plane, boat or other modes of transport, and is either one way to another place, or round trip traveling. It does not always require travel to another location, travel can also be a result of crossing a border, going into a rescue situation or being rescued. There are several ways by which people can travel from one place to another. These types of travel may include:

Emergency Evacuation and Medical Alert System: If you are traveling to an emergency destination, you will need some form of emergency evacuation and medical alert system. This is usually part of a comprehensive travel advisory that advises travelers of various security measures, health considerations and personal safety. These devices are very small, lightweight and waterproof that can easily fit in a pocket or travel bag and are capable of communicating with cellular towers in order to be heard if they are activated. These systems usually have multiple built-in emergency buttons, which when clicked can immediately connect with local authorities and send help if necessary. They are not as sophisticated as CICs for medical emergencies, but can save lives.

Drug Testing and Pre-screening: Some countries require travelers to submit to drug testing at the airport’s security checkpoint before being allowed to board. In recent times, the United States has started a program called Next Flight Safety that makes use of drug testing at the security checkpoint. A recent study shows that passengers who were subjected to this kind of drug testing performed a higher rate of blood alcohol concentration (BAC) when compared with passengers who were not subjected to the test. Most airlines now implement this new policy.

Security Screening: Passengers are required to submit to security screening before departure. The United States Federal Aviation Administration (FAA) also requires that all passengers be screened for infectious diseases. These checks are part of the TSA’s pre-boarding process, which aims to prevent passengers from bringing contagious diseases to the plane. Recent studies show that the percentage of passengers carrying an infectious disease is much higher on airplanes than at the airports.

Medical Exemption: Like the rest of the procedures in the passenger transportation category, medical testing exemptions vary according to the rules and regulations of different states. For example, in the United States, there is no legal authority that justifies passengers from undergoing tests like DNA profiling, fingerprinting or bar coding. When a passenger feels that he/she needs to undergo a specific procedure, he/she must apply for a medical exception. There are three medical exception categories under the law; they are based on gender, disability or medical history. A passenger who is elderly may also need to undergo a screening, in order to obtain a medical card or prescription.

Recovery Items: Some airlines offer recovery items for passengers who need to use bathroom facilities in aircraft cabins during flight. Electronic copies of travel receipts and other documentation are offered for this purpose. However, passengers have to produce original documentation for obtaining recovery items. For passengers who do not possess original documentation, they will be required to provide photo identification or a secondary form of documentation.
