A.2 KEY MEASURES (DEPENDENT VARIABLES) Table 2. Expanded key measures (dependent variables). Variable Ref. # Advantages Disadvantages 1.0 Vehicle Behavior 48 1.1 Speed 125, 50 1.1.1 Continuous More accurate profile. Large amounts of data. Expensive. 1.1.2 Discrete locations Less data. Cheaper. 1.1.3 Speed exceedances: high; low Distraction indicator. 1.1.4 Speed variance Distraction indicator. Best with continuous data. 1.2 Lane position 161, 48, 54 1.2.1 Continuous More accurate profile. Large amounts of data. Expensive. 1.2.2 Discrete locations Less data. Cheaper. 1.2.3 Lane excursions: right; left 23 Distraction indicator. More difficult to measure. 1.2.4 Lane variance Distraction indicator. Best with continuous data. 1.3 Acceleration 48, 54 1.3.1 Longitudinal: hard braking; delayed acceleration; braking without cause Excellent surrogate for distraction. 1.3.2 Lateral: swerves 39 Good surrogate for distraction. 1.3.3 Heave: bumps 125, 48 Not important. 1.4 Other vehicle interactions 39 47
