Multivariate poisson-lognormal model for modeling related factors in crash frequency by severity

Multivariate poisson-lognormal model for modeling related factors in crash frequency by severity

Aims: Traditionally, roadway safety analyses have used univariate distributions to model crash data for each level of severity separately. This paper uses the multivariate Poisson lognormal (MVPLN) models to estimate the expected crash frequency by two levels of severity and then compares those esti...
