Transportation planning models are typically used to estimate future traffic patterns, peak period traffic, travel time, and various environmental or other related traffic flow characteristics. Unfortunately, traffic safety is seldom, if ever, explicitly considered proactively during the transportation planning process. This omission is attributed to various factors, including the lack of avail...

Traumatic injury is responsible for more deaths among American adolescents and young adults age 14-24 than all other causes combined (Paulson 1983). Far and away the leading cause of traumatic injuries is traffic crashes (Robertson 1981; Lewis 1987). Traffic crashes have been cited as the cause of about half of all accidental deaths in adolescents and young adults and have also been cited as th...

In many cases crashes at intersections account for over 50% of all urban road crashes. The need to reduce these crashes has fostered considerable research on the development and evaluation of traffic safety at intersections. This paper introduces a micro-level behavioral approach for estimating the crash potential at unsignalized intersections for different traffic conditions. To this end, prox...

Poisson regression and negative binomial regression have been widely used to model the road crashes and to predict crash frequency. Zero inflated models have been shown to be a powerful tool to predict crash frequency when crash data are characterized by preponderance of zero. This paper presents the research work aiming to correlate the road traffic crash rate with road geometry and traffic ch...

Past research has uncovered personality influences on dangerous driving behavior and vehicle crashes (Furnham & Saipe, 1993; Matthews, Dorn, & Glendon, 1991). Recently, females between 16 and 20 years of age showed an increase in overall crash rate, while males within the same age group showed a decrease in overall crash rate (NHTSA, 2004; NHTSA, 2002). Adolescent and young adult females have b...

Work zones in the United States have approximately 700 traffic-related fatalities, 24,000 injury crashes, and 52,000 non-injury crashes every year. Due to future highway reconstruction needs, work zones are likely to increase in number, duration, and length. This study focuses on analyzing the effect of work zone duration mainly due to its policy-sensitivity. To do so, we created a unique datas...

The use of c44qatis, jspi$epprep4 throughguf thg world, and in many countries is increasing (1). After alcohol, the most frequently found psychoactive substance in the blood of motorists involved in traffic crashes is cannabis. The very high costs, in human and financial terms. of road traffic crashes underscores the need for a clear understanding of the contribution of cannabis use to the inci...

Our primary research question was whether teens obtaining their intermediate-level provisional operators permit (POP) in a graduated driver licensing (GDL) environment through driver education differed in crashes and traffic violations from teens who obtained their POP by completing a supervised driving certification log without taking driver education. A descriptive epidemiological study exami...

OBJECTIVE To describe changes in the incidence of hospitalised injury for New South Wales residents involved in non-traffic crashes for the period 1 July 1998 to 30 June 2007. DESIGN, SETTING AND PARTICIPANTS This study identified 37 480 NSW residents admitted to hospitals for injuries resulting from non-traffic crashes from the NSW Admitted Patients Data Collection during the study period. I...
