Description of the variables used in the prediction.
| Variables | Type | Role | Description |
| Truck Id | Numeric | Feature | The serial number of truck. | Truck type | Categorical | Feature | The type of the truck (i.e., BELAZ-L, BELAZ-M, and MT86). | Truck status | Categorical | Feature | The status of the truck (i.e., running, waiting, and stop). | -axis start | Numeric | Feature | The coordinate of the truck at the starting position. | -axis start | Numeric | Feature | The coordinate of the truck at the starting position. | -axis arrival | Numeric | Feature | The coordinate of the truck at the ending position. | -axis arrival | Numeric | Feature | The coordinate of the truck at the ending position. | Load status | Categorical | Feature | The load status of the truck (i.e., empty and coal). | Start node | Categorical | Feature | The node code of the starting position of the road. | Arrival node | Categorical | Feature | The node code of the ending position of the road. | Pressure | Numeric | Feature | A fundamental atmospheric quantity. | Wind speed | Numeric | Feature | A fundamental atmospheric quantity. | Temperature | Numeric | Feature | A fundamental atmospheric quantity. | Relative humidity | Numeric | Feature | A fundamental atmospheric quantity. | Precipitation | Numeric | Feature | A fundamental atmospheric quantity. | Rain | Categorical | Feature | A fundamental atmospheric quantity (i.e., yes and no). | Travel time | Date time | Target | The travel time of the truck on each link. |
