Sight Distance and Reaction Time. Sight Distance. Sight distance means the distance from which you can see and identify a hazard. You often see an object before youâre able to identify it as a hazard. If the stopping distance to an object is greater than the sight distance, youâre in danger of hitting the object.
The major methodology of this approach is the single-case experiment, or N = 1 design. Although there are many kinds of N = 1 designs, the most common are the ABAB design and the multiple-baseline design. An ABAB design, or reversal design, allows a researcher to confirm a treatment effect by showing that behavior changes systematically with conditions of No Treatment (baseline) and Treatment.
Wheel Alignment. A wheel alignment machine is the best tool for checking suspension and steering component damage after an accident. A wheel alignment is the adjustment of the suspension and steering systems that allows the tires to roll smoothly and correctly over the surface of the road. Itâs also the measurement of the suspension angles and the adjustment of the suspension and steering components.
