This study proposes a methodology for estimating places where people may perform additional activities with utilizing the concept of space-time prism. Decision about travel behaviour can be affected by time constraints of their life and spatial structure where they live. Considering such constraints is important to estimate which place is likely to be chosen for the additional activities. This study develops a method to estimating the place which people may choose as an additional destination. This method proposes the concept of path constrained potential path area (P-PPA) by incorporating the concept of space-time prism with information of revealed trip trajectories which can be taken by position detection tools such as GPS and so on. An efficient calculation algorithm with considering actual network structure is proposed. An empirical test has been carried out in the real network to check the proposed methodology.
