![]() ![]() These adjustments would include decreasing speed and increasing following distance. When Total Stopping Distance is increased, drivers need to make adjustments to the way they are driving to ensure driver, passenger and pedestrian safety. Braking distance is the distance the vehicle travels from the point at which the driver applies the brake until the vehicle actually comes to a complete stop. Reaction distance is the distance the vehicle travels from the point a driver perceives or decides that something is a hazard, until braking.īraking is what the driver does to slow a vehicle. For a driver, their reaction is taking their foot from the accelerator and applying the brake in order to stop the vehicle. Reaction is a person’s ability to respond physically and mentally to external stimuli. Perception is defined as “The ability to see, hear, or become aware of something through the senses.” Perception is relative and unique to each individual, especially visual perception. Speed is the greatest factor in Total Stopping Distance, but three other key components play large factors in Total Stopping Distance. Driver condition ( impaired coordination, leg/foot injury).The distance thereafter required to come to a complete stop is the braking distance. ![]() The time it takes to react and come into the correct braking position is the reaction distance. Once a driver perceives a need to slow or stop, a small amount of time passes. Total Stopping Distance is the sum of the perception distance, reaction distance and braking distance. Do you know how to come to a complete stop safely and swiftly to avoid injury? Do you recall what contributes to Total Stopping Distance? What is Total Stopping Distance? While your sense of sight is crucial, it’s also important to rely on your driver training. The lengths of the two lines appear to be different but are the same.A vast majority of the information you gather while driving is received through your vision, such as the cars around you, traffic signals, street signs, road construction, pedestrians and much more. An example is the Müller‐Lyer illusion shown in Figure. Presentation of multiple stimuli elicits a tendency to group some of them together and others apart, a phenomenon which can create optical illusions. Retinal disparity, the differences in images on the retinas of the two eyesĮye convergence, a necessary visual response in order to focus on a distant object Binocular cues, those used when looking at objects with both eyes, also function in depth perception. Relative motion (motion parallax), used in judging distance (when you are traveling in a car, near objects seen out the window seem to move rapidly, but far ones don't seem to move)īinocular cues. Texture changes (distinct bricks are seen in a near wall but become a pattern with increased distance) Linear perspective, the convergence of parallel tracks or lines as they recede into the distance Interposition, when one stimulus blocks the image of another Monocular cues, those used when looking at objects with one eye closed, help an individual to form a three‐dimensional concept of the stimulus object. The processes include use of both monocular and binocular cues. Perceptual processes function in the three‐dimensional organization of stimuli as well as in distance judgments.
