+***Pedestrian*** represents hourly pedestrian counts at 82 locations in Melbourne, Australia between 2009 and 2022 [1]. The processed dataset consists of 189,621 (univariate) time series, each of length 24 (i.e., representing 24 hours of data per time series). The data comes from automatic pedestrian counting sensors at different locations.  The task is to identify location based on the time series of counts. The dataset has been split into stratified random cross-validation folds.
