This paper illustrates a methodology developed to analyze the influence of traffic conditions, i.e. volume and composition on accidents on different types of interurban roads in Spain, by applying negative binomial models. The annual average daily traffic was identified as the most important variable, followed by the percentage of heavy goods vehicles, and different covariate patterns were found for each road type. The analysis of hypothetical scenarios of the reduction of heavy goods vehicles in two of the most representative freight transportation corridors, combined with hypotheses of total daily traffic mean intensity variation, produced by the existence or absence of induced traffic gives rise to several scenarios. In all cases a reduction in the total number of accidents would occur as a result of the drop in the number of heavy goods transport vehicles, However the higher traffic intensity, resulting of the induction of other vehicular traffic, reduces the effects on the number of accidents on single carriageway road segments compared with high capacity roads, due to the increase in exposure. This type of analysis provides objective elements for evaluating policies that encourage modal shifts and road safety enhancements.

Research on the unique experiences of deaf people is rare, and limited information exists regarding the nature and extent of violence against this population. Existing scholarship highlights the increased vulnerabilities of deaf individuals; however, there remains a paucity of research that examines how deaf and hard of hearing individuals perceive their own victimization. Also lacking is research on the experiences of deaf individuals outside of the United States, where cultural norms and the status of the deaf may be quite different. In this article, we examine the relationship between violence and disability among 60 deaf people from developing countries. Each respondent is seeking legal asylum in the United States, and their asylum depositions provide the data for analysis. Thematic analyses reveal that deaf individuals experience abuse and violence within various social institutions and draw upon social perceptions of disability to explain their negative treatment. Notably, respondents cite their status as "devalued persons" as the driving factor behind institutional and interpersonal experiences of violence and, in some cases, respondents internalize this devalued status. The results suggest social conceptualizations of disability and deafness are important to consider in the context of violence and abuse.
