A travel plan (historically referred to as a green travel plan) is a package of actions designed by a workplace, school or other organisation to encourage safe, healthy and sustainable travel options. By reducing car travel, Travel Plans can improve health and wellbeing, free up carparking space, and make a positive contribution to the community and the environment. Every Travel Plan is different, but most successful plans have followed a structured process in their development:

The UK Department for Transport defines workplace travel plans as a package of measures produced by employers to encourage staff to use alternatives to single-occupancy car use. The first Travel Plans in the UK were adopted in Nottingham by Nottinghamshire County Council in 1995. Travel plans are now common in the UK, and are becoming common in Australia and New Zealand.

A workplace can choose to develop a travel plan at any time, or could be required to develop a travel plan as a condition of planning consent for an expansion or new development. Typical actions in a workplace travel plan include improving facilities for pedestrians and cyclists (showers, lockers and cycle parking), promotion and subsidy of public transport, and encouraging carpooling, working from home and teleconferencing.

Travel is the movement of people or objects (such as airplanes, boats, trains and other conveyances) between relatively distant geographical locations.

The term "travel" originates from the Old French 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.^{[citation needed]}

"The World is a book, and those who do not travel read only a page."

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 or for the enjoyment of traveling. Travel may occur by human-powered transport such as walking or bicycling, or with vehicles, such as public transport, automobiles, trains and airplanes.

A plan is typically any diagram or list of steps with timing and resources, used to achieve an objective. See also strategy. It is commonly understood as a temporal set of intended actions through which one expects to achieve a goal. For spatial or planar topologic or topographic sets see map.

Plans can be formal or informal:

The most popular ways to describe plans are by their breadth, time frame, and specificity; however, these planning classifications are not independent of one another. For instance, there is a close relationship between the short- and long-term categories and the strategic and operational categories.

It is common for less formal plans to be created as abstract ideas, and remain in that form as they are maintained and put to use. More formal plans as used for business and military purposes, while initially created with and as an abstract thought, are likely to be written down, drawn up or otherwise stored in a form that is accessible to multiple people across time and space. This allows more reliable collaboration in the execution of the plan.
