How to select traffic flow / speed / occupancy in PEMSD4 & 8

[aptx1231]

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.

traffic_flow only：
"info": {
"data_col": [
"traffic_flow"
],
"weight_col": "cost",
"data_files": [
"PEMSD4"
],
"geo_file": "PEMSD4",
"rel_file": "PEMSD4",
"output_dim": 1,
"time_intervals": 300,
"init_weight_inf_or_zero": "zero",
"set_weight_link_or_dist": "link",
"calculate_weight_adj": false,
"weight_adj_epsilon": 0.1
}

traffic speed only：
"info": {
"data_col": [
"traffic_speed"
],
"weight_col": "cost",
"data_files": [
"PEMSD4"
],
"geo_file": "PEMSD4",
"rel_file": "PEMSD4",
"output_dim": 1,
"time_intervals": 300,
"init_weight_inf_or_zero": "zero",
"set_weight_link_or_dist": "link",
"calculate_weight_adj": false,
"weight_adj_epsilon": 0.1
}

traffic occupancy only：
"info": {
"data_col": [
"traffic_occupancy"
],
"weight_col": "cost",
"data_files": [
"PEMSD4"
],
"geo_file": "PEMSD4",
"rel_file": "PEMSD4",
"output_dim": 1,
"time_intervals": 300,
"init_weight_inf_or_zero": "zero",
"set_weight_link_or_dist": "link",
"calculate_weight_adj": false,
"weight_adj_epsilon": 0.1
}
