Travel is the movement of people or objects (such as airplanes, boats, trains and other conveyances) between relatively distant geographical locations. 'Travel' can also include relatively short stays between successive movements.
The term "travel" originates from the Middle English word travail. The term also covers all the activities performed during a travel (movement). A person who travels is spelled "traveler" in the United States, and "traveller" in the United Kingdom.
Purpose and motivation
Reasons for traveling include recreation, tourism or vacationing, research travel for the gathering of information, for holiday to visit people, volunteer travel for charity, migration to begin life somewhere else, religious pilgrimages and mission trips, business travel, trade, commuting, and other reasons, such as to obtain health care or fleeing war. Travel may occur by human-powered transport such as walking or bicycling, or with vehicles, such as public transport, automobiles, trains and airplanes. Motives to travel include pleasure, relaxation, discovery and exploration, getting to know other cultures and taking personal time for building interpersonal relationships. Travel may be local, regional, national (domestic) or international. In some countries, non-local internal travel may require an internal passport, while international travel typically requires a passport and visa. A trip may also be part of a round trip, which is a particular type of travel whereby a person moves from their usual residence to one or several locations and returns.
It's important to take precautions to ensure travel safety. When traveling abroad, the odds favor a safe and incident-free trip, however, travelers can be subject to difficulties, crime and violence. Some safety considerations include being aware of one's surroundings, avoiding being the target of a crime, leaving copies of one's passport and itinerary information with trusted people, obtaining medical insurance valid in the country being visited and registering with one's national embassy when arriving in a foreign country. Many countries do not recognize drivers' licenses from other countries; however most countries accept international driving permits. Automobile insurance policies issued in one's own country are often invalid in foreign countries, and it's often a requirement to obtain temporary auto insurance valid in the country being visited. It's also advisable become oriented with the driving rules and regulations of destination countries. Wearing a seat belt is highly advisable for safety reasons and because many countries have penalties for violating seatbelt laws.

Tourism has become a popular global leisure activity. In 2010, there were over 940 million international tourist arrivals, with a growth of 6.6% as compared to 2009. International tourism receipts grew to US$919 billion (euro 693 billion) in 2010, corresponding to an increase in real terms of 4.7%. As a result of the late-2000s recession, international travel demand suffered a strong slowdown beginning in June 2008, with growth in international tourism arrivals worldwide falling to 2% during the boreal summer months. This negative trend intensified during 2009, exacerbated in some countries due to the outbreak of the H1N1 influenza virus, resulting in a worldwide decline of 4% in 2009 to 880 million international tourists arrivals, and an estimated 6% decline in international tourism receipts.
