The continuous increase of tourism flow in urban destination could create undesirable effects concerning the decline of population, changes in tradition, changes in community cohesion, pollution, congestion and other negative impacts on residents. All these factors explain why local governments today are increasingly struggling with the choice of restricting the number of tourist presences, even though aware that an excessive reduction in visitor numbers can also negatively affect the monetary gain of the local tourism sectors. How to determine and achieve the "best" compromise between these two opposite needs is one of the ultimate goals pursued by studies on tourism carrying capacity (TCC) and various policies experimented by many destinations affected by over-tourism. Calculating the carrying capacity of a tourism destination using a linear programming method is a process that follows these operative steps:
  • 1. identify the tourism sub-systems of a destination, especially regarding tourism facilities and services;
  • 2. classify the type of users are often utilizing those sub-systems;
  • 3. determine the level of usage of these sub-systems by user profile;
  • 4. lastly proceed with the quantitative analysis with the fine scope to maximize the revenue of the destination through understanding the daily expenditure per each profile.

Real tourism flow
