    Random-Parameter Multivariate Negative Binomial Regression for Modeling Impacts of Contributing Factors on the Crash Frequency by Crash Types by Chenzhu Wang, Fei Chen, Jianchuan Cheng, Wu Bo, Ping Zhang, Mingyu Hou, Feng Xiao

    Published 2020-01-01
    “…Therefore, we propose the random-parameter multivariate negative binomial (RPMNB) model to analyze the influence of the traffic, speed, road geometry, and sight characteristics on the rear-end, bumping-guardrail, other, noncasualty, and casualty crashes. Subsequently, we compute the goodness-of-fit and predictive measures to confirm the superiority of the proposed model. …”

    Determination of Effective Thoracic Mass by Jeffrey H. Marcus

    Published 1996-01-01
    “…Utilizing previously reported lateral and frontal impact tests with human cadaveric test specimens in a number of different conditions, the effective thoracic mass is computed. The effective thoracic masses are then computed for a variety of crash dummies exposed to identical test conditions.…”
