Vehicle Backover Avoidance Technology Study

Vehicle Back Up Study

The size of the safety problem can only be roughly estimated because many of the backover crashes that occur on private property are not recorded in State or Federal crash databases, which focus on crashes occurring in traffic-ways. Supplementing NHTSA crash records with death certificate reports, backover crashes involving all vehicle types are estimated to cause at least 183 fatalities annually. In addition, between 6,700 and 7,419 injuries result from backover crashes per year. A significant portion of these injuries are minor.

2006 Traffic Fatalities and Injuries Assessments

Traffic Fatalities GraphA preview of results from the 2006 Annual Assessment of Motor Vehicle Traffic Crash Fatalities and Injuries shows that the number of people killed in the United States in motor vehicle traffic crashes declined from 43,510 in 2005 to 42,642, the lowest level in five years.

The Effect of Width and Separation In Rear Window Defroster Lines On The Identification of Obstacles

Rear Window ViewA static, indoor study was conducted to assess the effects of rear window defroster/defogger line width and separation on the identification of obstacles located to the rear of a motor vehicle. Additional independent variables included participant age, rake angle of the rear window, and target location in the rearward field of view. The targets used in this simulated backing/reversing task, as seen through the interior rearview mirror, were a trash can (low contrast) and a child's bicycle (high contrast). The dependent variables were reaction time to correctly identify the target, and subjective ratings of how easily targets could be seen through the simulated defroster/defogger line patterns.

Color Identification In The Visual Periphery: Consequences for Color Coding Of Vehicle Signals
ARC NetworkThis field study investigated the efficiency of color coding for peripheral identification of vehicle signals. Specifically, the study dealt with identification of stimuli as "yellow" or "red" when presented at intensities corresponding to typical turn signal lamps and side marker lamps. Turn signal lamps were studied both during bright, sunny conditions and at night, while side marker lamps were studied at night only. We used two different yellow stimuli and two different red stimuli. For each color category, one stimulus was relatively far from the contrasting color category while the other stimulus was relatively near. Four viewing angles were used: 0, 10, 20, and 30 degrees from visual fixation. A total of 28 subjects participated, ranging from 21 to 78 years old.
 
Conspicuity and Glare Properties of Daytime Running Lights: Effects of Lamp Separation and Intensity
 Glare
 
This study evaluated the influences of lamp separation and lamp intensity on the effectiveness of daytime running lights. Subjects performed two tasks. They rated discomfort glare from a pair of lamps, and evaluated the conspicuity of the same lamps. The same nine stimuli were used in both the glare and conspicuity portions of the study. These nine stimuli were obtained by the orthogonal combination of three levels of luminous intensity directed towards the subject's eyes from the two lamps (14,000, 3,500, and 875 cd), and three levels of lamp separation (1.05, 0.65, and 0.25 m-edge to edge). The study was performed outdoors, on bright, sunny days. The viewing distance was 20 m.

Effects of Nonplanar Driver Side Mirrors on Lane Change Crashes
 
 
Mirror PictureThis quasi-experiment investigated the effects on lane change crashes of nonplanar (spherical convex and multiradius) driver-side mirrors compared to planar mirrors. The analysis was based on 1,062 crashes reported from 1987 to 1998 to Finnish insurance companies, for vehicles with passenger-side spherical convex mirrors and one of three types of driver-side mirror (planar, spherical convex, or multiradius).
 
Effects of Color on the Detection Of Retroreflective Pedestrian Markings by Normal and Color Deficient Drivers
 Color
 
A nighttime field study was conducted to assess the effects of color on the detection of retroreflective pedestrian markings by color normal and color deficient drivers. Participants seated in a stationary vehicle, with its low-beam headlamps on, indicated when a moving pedestrian, who wore colored retroreflective markings on her legs, was just detectable. Independent variables included color (red, yellow, green, and white), retroreflective power, participant age, color-vision capability, and location of the stimulus in the visual field (centrally or peripherally located).
 
The Effect of Lead-Vehicle Size on Driver Following Behavior
 
Vehicle Lead
The effect that lead-vehicle size (specifically, height and width) has on a passenger car driver's gap maintenance under near optimal driving conditions (e.g., daytime, dry weather, free-flowing traffic) was examined. The data were obtained from a random sample of licensed drivers who drove an instrumented passenger car, unaccompanied, as their personal vehicle for two to five weeks.
