Novice teenage driver cell phone use prevalence
Novice teenage drivers have high crash rates due to inexperience; therefore, cell phone-related secondary task engagement (distracted driving) is likely to aggravate crash risk for this population. A previous study of teenage distracted driving behavior, found that 34% of 16-17- year-olds had...
Validity of the C-RDS self-reported risky driving measure
This study examined the reliability and validity of the Checkpoints Risky Driving Scale (C-RDS) in relation to the Dula Dangerous Driving Index (DDDI) and an objective measure of risky driving. Naturalistic and survey data were collected over an 18-month period from 42 newly-licensed teenage...
Anthropometric and postural variability : limitations of the boundary manikin appraoch
Human figure models are commonly used to facilitate ergonomic assessments of vehicle driver stations and other workplaces. One routine method of workstation assessment is to conduct a suite of ergonomic analyses using a family of boundary manikins, chosen to represent a range of anthropometric...
Statistical analysis of body shapes for parametric human body modeling
Finite?element (FE) human body models (HBM) enable high?fidelity representations of anatomy in crash simulations. Most current FE HBM s are based on the anatomy of one or a few individual s , including details of the skeleton, soft tissues, and overall body shape. As part of a broader effort to...
Geometric visibility of mirror mounted turn signals
Turn signals mounted on exterior rearview mirrors are increasingly being used as original equipment on passenger cars and light trucks. The potential for mirror-mounted turn signals (MMTS) to improve the geometric visibility of turn signals is examined in this paper. A survey of U.S. and UN-ECE...
Modeling vehicle ingress and egress using the human motion simulation framework
The ease of getting into and out of passenger cars and light trucks is a critical component of customer acceptance and product differentiation. In commercial vehicles, the health and safety of drivers is affected by the design of the steps and handholds they use to get into and out of the cab....
Modeling body shape from surface landmark configurations
Detailed statistical models of body size and shape are valuable for wide range of statistical analyses. Most body shape models represent a single posture, usually standing. Previous efforts to model both posture and body shape have parameterized posture using joint angles. This paper presents a sta...
Robust truck cabin layout optimization using advanced driver variance models
One important source of variance in the performance and success of products designed for use by people is the people themselves. In many cases, the acceptability of the design is af- fected more by the variance in the human users than by the vari- ance attributable to the hardware from which the...
Maintaining balance in seated reaches
The aim of this study is to gain insight into how people maintain their balance while performing seated reaches. The requirement to maintain balance is a significant contributor to reach difficulty, and in some cases exceeds strength and range of motion as the primary limiting factor in achieving a...
Standing reach envelopes incorporating anthropometric variance and postural cost
Standing reach envelopes are important tools for the design of industrial and vehicle environments. Previous work in this area has focussed on manikin-based (where a few manikins are used to simulate individuals reaching within the region of interest) and population-based (where data are gathered...
