In the present study, ethylene-vinyl acetate (EVA) and crumb rubber (CR) were used as bitumen modifiers. The experiment was designed by response surface methodology (RSM) at different levels of modifier additives based on central composite design (CCD). Next, Superpave protocol followed to evaluate modified performance temperatures compared with unmodified bitumen. this regard, high temperature...

Distracted driving has long been acknowledged as one of the main contributors to crashes in the US. According to past studies, driving behavior proved to be influenced by the socioeconomic characteristics of drivers. However, only few studies attempted to quantify that influence. The study proposed a Crash Risk Index to estimate the crash risk associated with the socioeconomic characteristics o...

There is a need for large-scale, real world, diverse, and context rich vehicle acceleration catalog that can be used to design, analyze, compare various intelligent transportation systems. This paper fulfills three primary objectives. First, it provides such through the Surface Accelerations Reference, which openly available as an interactive analytics tool well open downloadable dataset. The R...

Rural intersections account for around 30% of crashes in rural areas and 6% all fatal crashes, representing a significant but poorly understood safety problem. Crashes at are also problematic since high speeds on intersection approaches present which can exacerbate the impact crash. Additionally, often underserved with EMS services further contribute to negative crash outcomes. This paper descr...

In this study we describe in 9- and 18-day-old CD1 mice (i) the basal and stress-induced activity of markers of the HPA system in blood, brain and pituitary, (ii) the effects of a 24-h maternal deprivation and (iii) the influence of anogenital stimulation (stroking) in deprived pups on these markers. We found low basal concentrations of ACTH and corticosterone at postnatal day (pnd) 9 and no or...

Among a large number of existing artificial intelligence (AI)-based techniques, artificial neural network (ANN) is one of the most widely used techniques, which has been applied to many road engineering problems. They are especially useful as predictive models because they do not require prior knowledge of the input data distribution and have shown high prediction performance. However, despite ...
