The general approach of TECAPSY is to target daily commuters first (company commuters, students, industrial areas) and visitors to events.     The potential segments of the market are more numerous: any area or activity that generates a bidirectional regular traffic may be included. The knowldege acquired will help new cities or regions joining TECAPSY to identify potential users and to assess the benefits of the introducing the system.     The key point of the system to work smoothly is to reach the “critic mass” of users. Once reached, the different segments of the market can begin interact in a way that meets the demands of a wider variety of journeys.
