The purpose of the study is to evaluate the impacts of the variables on site selection decision of the spectators just before the main activity in order to engage in eating, having fun and performing other types of activities. A multinomial logit modelling framework is hired to model activity patterns within PSE circumstances. Activities were classified into three groups that are "Eating", "Entertainment", and "Other". Model estimation on PSE survey data set from selected stadiums in Istanbul shows that due to the congestion, as travel time and activity duration increase the spectators inclined to be around the stadium 184 minutes in average before the starting time of the main activity. The results obtained from this study can be used as a micro input for the macro studies such as transportation master plans and urban plans and can offer complementary research areas for PSE traffic management and urban planning.
