Travel is the movement of people between relatively distant geographical locations, and can involve travel by foot, bicycle, automobile, train, boat, airplane, or other means, with or without luggage, and can be one way or round trip.12 Travel can also include relatively short stays between successive movements.
The origin of the word "travel" is most likely lost to history. The term "travel" may originate from the Old French word travail.3 According to the Merriam Webster dictionary, the first known use of the word travel was in the 14th century. It also states that the word comes from Middle English travailen, travelen (which means to torment, labor, strive, journey) and earlier from Old French travailler (which means to work strenuously, toil). In English we still occasionally use the words travail and travails, which mean struggle. According to Simon Winchester in his book The Best Travelers' Tales (2004), the words travel and travail both share an even more ancient root: a Roman instrument of torture called the tripalium (in Latin it means "three stakes", as in to impale). This link is fascinating given the extreme difficulty of travel in ancient times. Also note the torturous connotation of the word "travailler." Today, travel may or may not be much easier depending upon the destination you choose (i.e., Mt. Everest, the Amazon rainforest), how you plan to get there (tour bus, cruise ship, or oxcart), and whether or not you decide to "rough it (see extreme tourism and adventure travel). "There's a big difference between simply being a tourist and being a true world traveler," notes travel writer Michael Kasum.
It's important to take precautions to ensure travel safety.7 When traveling abroad, the odds favor a safe and incident-free trip, however, travelers can be subject to difficulties, crime and violence.8 Some safety considerations include being aware of one's surroundings,7 avoiding being the target of a crime,7 leaving copies of one's passport and itinerary information with trusted people,7 obtaining medical insurance valid in the country being visited7 and registering with one's national embassy when arriving in a foreign country.7 Many countries do not recognize drivers' licenses from other countries; however most countries accept international driving permits.9Automobile 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.9 It is also advisable to become oriented with the driving rules and regulations of destination countries.9 Wearing a seat belt is highly advisable for safety reasons and because many countries have penalties for violating seatbelt laws.9
There are three main statistics which may be used to compare the safety of various forms of travel (based on a DETR survey in October 2000):10
