     rural roads carry less than fifty percent of the traffic in the united states. however, more than half of the traffic accident fatalities occurred on rural roads. this research focuses on analyzing injury severities involving single-vehicle crashes on rural roads, utilizing a latent class logit (lcl) model. similar to multinomial logit (mnl) models, the lcl model has the advantage of not restricting the coefficients of each explanatory variable in different severity functions to be the same, making it possible to identify the impacts of the same explanatory variable on different injury outcomes. in addition, its unique model structure allows the lcl model to better address issues pertinent to the independence from irrelevant alternatives (iia) property. a mnl model is also included as the benchmark simply because of its popularity in injury severity modeling. the model fitting results of the mnl and lcl models are presented and discussed. key injury severity impact factors are identified for rural single-vehicle crashes. also, a comparison of the model fitting, analysis marginal effects, and prediction performance of the mnl and lcl models are conducted, suggesting that the lcl model may be another viable modeling alternative for crash-severity analysis.
