Here is a link , with track of the students of IaaC for a day , to understand the movement of students with diverse cultural background.It was carried out with the direct, voluntary and conscious participation of the students . From the data we can see that most of them would pass by the touristic zone but it was just a transition as most of their destination especially during weekdays was just residential area. This map helps to understand the nodes at which their was maximum and minimum movement and the path .
