Governments, city planners, public transport companies and resort owners are continually searching for the answers to these questions. Some of the answers are obvious, others need to be researched. Those selling travel and tourism, having obtained this type of information, undertake a task in which they try to communicate with their "target markets" using such means as advertising, promotion and others.
