TSAD Statistical Analysis (SA)
The Statistical Analysis Group applies statistical methods in the analysis of traffic safety issues. Areas of current interest include collision-avoidance and crashworthiness. Projects generally involve the analysis of accident and travel data to study the risk of accident involvement or the risk of injury in a collision. Our expertise includes the following:
Analysis of occupant protection issues such as airbag effectiveness and vehicle incompatibility.
Creating multivariate models to quantify the relationship of various explanatory variables to the risk of accident involvement. Examples include the relationship of truck configuration and operating environment to the risk of truck accidents, or the relationship of driver age and gender to passenger car accident risk.
Developing methodologies to analyze precollision factors in support of collision-avoidance technologies.
The members of this group often work with other divisions in providing experimental designs or in developing statistical models: for example, to identify factors associated with misadjusted truck air brakes or to study heavy truck mirrors.
