Anthropometry Update: Is the 6-year old ATD Representative of Age-matched Children?

Principal Investigator:  Amanda Agnew, PhD, Ohio State University

This study investigates whether the quality of anthropometric data, as it pertains vehicle safety, will improve when direct methods are used to collect it, and whether current ATDs can be improved with CRS-specific anthropometric data bases. The objective of this project is to determine whether currently-accepted anthropometric data, upon which pediatric ATDs are designed, are an accurate representation of children ages 4-7 years sitting in booster seats. The long-term goal is to ensure that anthropometric data is being collected in ways that directly relate to pediatric vehicle safety, and to ensure that current databases are up-to-date and accurate for today’s U.S. population.

Exploration of the Effect of Positive Reinforcement on Teen Driving Behavior

Principal Investigator: Yi-Ching Lee, PhD, The Children's Hospital of Philadelphia

New technologies such as in-vehicle monitoring systems offer the potential to improve safety by generating alerts and positive feedback when certain driving practices are detected. With the combination of positive feedback and motivational incentives, behaviors from risk-taking-prone teen and young drivers may be changed to be more positive and less risky. The long-term goal is to understand the effect of positive reinforcement on the shaping of teen and youth driving behaviors by gathering teen and young drivers’ perspectives on positive reinforcement through reviews of technologies, collection of qualitative and quantitative data, and discussion with experts and IAB members.
