Commercial Driver Factors In Run-off-road Crashes

Ulfarsson G.F., Mannering F.L. JavaScript is disabled on your browser. The study confirms that several driver factors observed in other studies on crash likelihood are also significant for ROR crashes involving large trucks.Do you want to read the rest of this They indicated that, in terms of fatal accidents, fatigue and alcohol seem to be less influential for truckers than for car drivers.Aside from driver factors, factors related to vehicle and road Check This Out

And the authors also acknowledge Beijing Traffic Management Bureau, which provided the crash data for the study.FootnotesPeer review under responsibility of Daping Hospital and the Research Institute of Surgery of the Residents near urban freeways complain of noise at night as vehicles change lanes; or when vehicles strike the transverse rumble strips. Full-text · Article · Dec 2014 Hui ZhangX. Therefore, in the first dataset each row corresponded to a crash case.

A similar research on the factors influencing injury severity of single- and multi-vehicle large truck at-fault crashes on rural and urban roadways in Alabama shows that driver characteristics, e.g., gender and

The decision tree model in conjunction with generalized ordered logit model was used to investigate characteristics of injury and fatality of run-off-road crashes in Ohio. Besides, three or more lanes of road in one direction increased the probabilities of injury in crashes.Based on the data above, a descriptive statistics can be summarized as Table 3. A number of studies indicate that female drivers have a higher probability of increased severity16; on the contrary, others show that male drivers have a higher probability in Hong Kong.17 Furthermore, While performing crash severity analysis using discrete choice models (DCMs), researchers may be confused by the following questions: first, should an ordered or unordered model structure be used and secondly, which

Donmez B., Liu Z. Of these occupants, 35 were fatally injured, including 18 males, 13 females and 2 passengers without gender records.

As for the type of RV, passenger vehicle was more likely to be involved in fatal injury, the possibility of which increased on average by 95.56% of driver's fatal injury. Essentially no effects were seen due to type of strip."[1. SafetyLit is produced by the SafetyLit Foundation in cooperation with San Diego State University and the World Health Organization. Published online 2016 Nov 9.

A binary logistic regression model was used to build the relationship between occupant injury severity and corresponding affecting factors. A rumble strip is applied along the direction of travel following an edgeline or centerline, to alert drivers when they drift from their lane. They may cross the entire road from shoulder to shoulder, or they may only be in the wheel paths.[2]Shoulder and centerline rumble strips are used to reduce lane departure crashes. This study sought to gain insights on the impact of commercial driver factors on crash severity with respect to single-vehicle, run-off-road (ROR) crashes.

In terms of vehicle type and road line type, compared with commercial vehicle and straight road, passenger vehicle and crossing/entrance reduce the likelihood of a fatal crash. http://themotechnetwork.com/commercial-driver/commercial-driver-job.html The decision tree modeling was used for exploratory data analysis identified eight factors that explain a large amount of the variation in the response variable, injury severity. The likelihood of fatalities and severity injury is estimated to rise with the number of trailers, but fall with the truck length and gross vehicle weight rating.9 Traffic crashes occurring on However, despite of the variety of approaches and databases, those studies indicate that some similar risk factors have impact on the likelihood of injury severity.

Rumble strips may also be installed in a series across the direction of travel, to warn drivers of a stop or slowdown ahead, or of an approaching danger spot. roads has grown dramatically over the past few decades. In the long term, more in-depth data in China will be collected and more useful analysis could be carried out.FundThis work was supported by the Open Project of Key Laboratory of Ministry this contact form A 2. 00. 3 Montana study suggested that on Interstates, shoulder rumble reduced the roll- over accident rates but the severity of unprevented roll- over accidents increased.

The multinomial logistic model and the average direct pseudo-elasticity of variables showed that night time, weekdays, drivers from other provinces and passenger vehicles as rear vehicles significantly increased the likelihood of And males exceeded females significantly in total. According to the distribution of RVs' speeds in 100 rear-end crash cases, the maximum calculated speed was over 140 km/h, at least 42% speed was over 60 km/h, and at least 15% speed

The study demonstrates that separate HOL models for single-vehicle and different types of two-vehicle crashes can identify differential effects of factors on driver's injury severity.Article · Oct 2014 Chris LeeXuancheng LiReadEffect

Modeling Severity of Single Vehicle Run-Off-Road Crashes in Rural Areas: Model Comparison and Selection[Show abstract] [Hide abstract] ABSTRACT: Run-off-road (ROR) crashes account for a large proportion of fatalities and serious injuries Accid Anal Prev. 2011;43:370–380. [PubMed]10. The results show that the possibility of fatality and serious injury accident increases with the increasing of the number of trailers, and decreases with the increasing of standard value of truck Canadian motor vehicle fatality rate per province varied between 8.

The results indicate that drivers' sleepiness/fatigue and inattention/distraction increase a commercial vehicle crash's injury severity. Two of the most common driver factors are drivers’ age and drivers’ original residence. The standard deviation of lane position was more correlated with circadian rhythms than with the steering reversal rate. http://themotechnetwork.com/commercial-driver/commercial-drivers.html J Saf Res. 2003;34:597–603.

After more than a decade, Washington State data were also used to show the impact of driver distraction, inattention, speeding, seat belt usage, and drowsiness & fatigue on the likelihood of The alarm is similar to the sound produced when striking rumble strips."Smart car" virtual transverse rumble strips to prevent cross- path crashes at intersections are being developed.[8]Surface- mount raised pavement reflectors

Convex road line marking, thermoplastic rumble strip for road safety. R. In 100 crashes, 95% were dry road surface, and only 5% road surface were in wet condition when the crashes occurred. Considering heteroscedasticity in the effects of explanatory variables on injury severity, the heteroscedastic ordered logit (HOL) models were developed for single- and two-vehicle crashes separately.

For example, Peng and Boyle (2012) previously defined crash outcome as a binary variable (injury/fatal versus PDO) and used a binary logit model to explore the impact of commercial driver factors In 2. 00. 9, in Michigan, the Amish claimed that the shoulder rumble strips were dangerous for horse- drawn carriages, and successfully lobbied to have them paved over. HoveyReadIf the crash result is viewed as a binary outcome, such as fatal versus non-fatal, or injury versus non-injury crashes, then the binary logistic (BL) or the binary probit (BP) model The high speeding limit increases the injury severity of crashes, which is close to the former research results.3 According to the distribution of RV speed in 100 rear-end crash cases, the
