Description of the Data

The dataset to be released is called ‘People Flow Data’, which consists of spatio-temporal data of particles processed from Person Trip Survey Data (PT Data). The origin survey is collected by a local authority of each area, aims at studying the actual daily travel behavior in cities with a large population (1%~3% sampling rate). The dataset provides individuals’ minute-to-minute location information based on detailed network data. We open the whole dataset in the Tokyo area as a training dataset for participants to model and calibrate the developed model. For the test dataset, a synthetic population contain demographic attributes as age, gender, and occupation and their home location is provided.
