This paper briefly describes a continuous market information system for the travel industry in Sweden and shows various applications and usage possibilities. The paper shows how the system can be used to monitor basic market volumes as number of trips, number of nights and money spent for the most important types of travelling, i.e. private and business travel, in Sweden and abroad, and trips including overnight stays as well as longer one-day trips. It is also illustrated how the overall travel volumes can be described in terms of travel month/season, destination, means of transport, type of accommodation, main purpose and type of travel arrangement. It is demonstrated how this data can be used to describe and monitor various sub-markets.
