Studies have shown that the effect of passengers on accident propensity among young drivers is ambiguous—in some cases positive and some negative. In Sweden, various kinds of information are compiled in registers, including a national accident database and exposure data collected in a national investigation of the driving habits of license holders. Access to such data offers a good opportunity ...

This research deals with axial and oblique impact crash tests on simple and hybrid composite tubes. Axial and oblique impact tests have been generated on simple and hybrid composite tubes with one, two and three layers. A drop test rig was used to conduct the experiments. Furthermore, in order to gain more detailed knowledge about the crash process, finite element simulations of the experim...

We study a rational expectation model of bubbles and crashes. The model has two components : (1) our key assumption is that a crash may be caused by local self-reinforcing imitation between noise traders. If the tendency for noise traders to imitate their nearest neighbors increases up to a certain point called the \critical" point, all noise traders may place the same order (sell) at the same ...

background: motor vehicle crashes (mvc) are considered to be the most common safety challenge, causing more than a million deaths worldwide annually. objectives: the current study was aimed at identifying the etiological role of human and vehicle safety factors in road crashes, and their effects on the severity of injury and fatality in the sistan and baluchistan province, south east iran. pati...

This study investigated the snowstorm impact on Wisconsin state highway system and assessed the winter maintenance effort in improving highway safety from a macroscopic perspective. Though the inverse relationship between the de-icing material consumption and the crash counts during the snowstorms is not reflected in the analysis, it implies that causes of snowstorm crashes are multifold. The f...

OBJECTIVE This study examined gender effects in six geometric scenarios of 2-vehicle crashes in which an involved driver could potentially ascertain the gender of the other driver prior to the crash. METHOD The actual frequencies of different combinations of the involved male and female drivers in these crash scenarios were compared with the expected frequencies if there were no gender intera...

A most commonly identified exogenous factor that significantly affects traffic crash injury severity sustained is the collision type variable. Most studies consider collision type only as an explanatory variable in modeling injury. However, it is possible that each collision type has a fundamentally distinct effect on injury severity sustained in the crash. In this paper, we examine the hypothe...

When I was studying at Berkeley with David and Ruth Collier in the first decade of the 2000s, a recurring question on our minds was whether the shift to neoliberalism constituted a “new critical juncture” for Latin American politics. In graduate seminars, we frequently debated the political consequences of neoliberal reforms and how to make sense of the ensuing transformations of party systems ...
