Pressure label explanation.

LabelNameExplanationData type

1Behaviour typeIncluding three types of driver behaviour.Classified variable (0-CF, 1-left LC, 2-right LC)

2B-LC5 seconds before LC.Dummy variable
3D-LCThe duration changing from current lane to target lane.
4A-LC5 seconds after LC.

5Left rearview mirror check stateWhether the driver checked the rearview mirror.Dummy variable (1-check, 0-no check)
6Right rearview mirror check state

7Vision pressure from right hand road infrastructureThe vision pressure from right hand infrastructure.
8Vision pressure from left hand road infrastructureThe vision pressure from left hand infrastructure.
9Current laneFront vehicleThe vision pressure from the front vehicle on current lane.
10Rear vehicleThe vision pressure from the vehicle behind the test vehicle on current lane.
11Target laneFront vehicle (near)The vision pressure from the nearest front vehicle on target lane.
12Vision pressure from nearby vehiclesFront vehicle (far)The vision pressure from the vehicle ahead of the nearest front vehicle on target lane.Continuous data (calculated by the model in Section 3)
13Rear vehicleThe vision pressure from the nearest vehicle behind the test vehicle on target lane.
14Adjacent laneFront vehicle (near)The vision pressure from the nearest front vehicle on adjacent lane
15Front vehicle (far)The vision pressure from the vehicle ahead of the nearest front vehicle on adjacent lane.
16Rear vehicleThe vision pressure from the nearest vehicle behind the test vehicle on adjacent lane.

Note. This value is only valid when the driver checked rearview mirror.
