If you want to predict a particular piece of data individually, i.e., traffic flow / speed / occupancy, you need to modify the PEMSD4 or PEMSD8/config.json under the dataset, note the part highlighted below, and modify it to look like this:
There is a large difference in the magnitude of these three types of data, and in past articles where traffic flow predictions have typically been made, wanting to select a particular type of data in isolation requires the modifications below.
Most articles need to be set to traffic_flow if you wish to reproduce the results of past articles.
