Roadside vegetation provides numerous environmental and psychological benefits to drivers. Previous studies have shown that natural landscapes can effectively lower crash rates and cause less stress and frustration to the driver. However, runoff the road crashes resulting in a collision with a tree are twice as likely to result in a fatality, thus reinforcing the need to examine the placement o...

This study adopted the Highway Safety Information System’s (HSIS) data for crashes occurred on road segments to develop supervised machine learning prediction models. Five models are developed: Linear Regression (LR), Generalize Additive Model (GAM), Random Forest (RF), Support Vector Machine (SVM), and Artificial Neural Network (ANN). A comparison among five model was performed using root mean...

Collisions with dangerous roadside obstacles and rollovers are responsible for many injuries and deaths in highways worldwide. International crash data indicate that roadside characteristics contribute to more than half of all run-off-road injury crashes (RORIC) involving serious injury or death. Furthermore, roadside geometric characteristics are believed to be the leading cause of rollover in...

OBJECTIVE To investigate the association between kava use and the risk of four-wheeled motor vehicle crashes in Fiji. Kava is a traditional beverage commonly consumed in many Pacific Island Countries. Herbal anxiolytics containing smaller doses of kava are more widely available. METHODS Data for this population-based case-control study were collected from drivers of 'case' vehicles involved i...

Traffic crashes are one of the main reasons for deaths many people and loss property. Road safety is a crucial aspect transportation that aims to prevent injuries on road, several contributing factors affect it. In this study, binary probit model using N-Logit software was applied crash-related data examine contribution variables severe crash outcomes in Al-Diwaniyah City. Crash severity (the d...

a spinal cord injury (sci) refers to any injury to the spinal cord or nerves at the end of the spinal canal that is caused by trauma instead of disease often causes permanent changes in strength, sensation and other body functions below the site of the injury. road traffic collision (rtc) or car crash occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other...

OBJECTIVE The objective of the present study was to validate sequelae prediction by the Maximal Injury Impairment Score (M-IIS) in comparison with the Functional Independence Measure (FIM) assessed at 1-year follow-up of severe road crash victims. METHODS The study population came from "the Etude et Suivi d'une Population d'Accidentés de la Route dans le Rhône" (ESPARR; Rhône Area Road Crash ...

human factors issues associated with roadway design and operations are critical components of improving highway safety. first, the three major components of highway safety are driver behavior, vehicle safety, and roadway safety. the general philosophy in roadside safety follows the priorities of (1) remove the hazard, (2) relocate the hazard, (3) make the hazard forgiving, and (4) shield the ha...
