Transportation Safety and Impact Analysis

Abstract This study investigates the relationship between road geometry and traffic crashes on rural state roads in Zonguldak, Turkey, between 2016 and 2022. The objective is to quantify how specific combinations of geometric elements influence average crash frequency per kilometer. A total of 941 crashes were analyze…

Bridge protective barriers are crucial in preventing vehicle exits and mitigating the effects of collisions. This study evaluates the structural response of the Oregon triple-tube bridge rail under MASH 2016 Test Level 4 (TL-4) loading using a combination of full-scale crash testing and nonlinear finite element (FE) a…

It is well established that an anti-intrusion beam is a passive safety system that serves an essential role for passengers during collisions. In this study, the influence of internal reinforcements on the bending failure of a cylindrical aluminum tube was systematically investigated through a series of composite beam…

Curbs are commonly used along roadsides, even though they carry the risk of causing potential hazards. When vehicles leave the roadway, curbs can disrupt vehicle stability and cause the vehicle to elevate. This may lead to undesirable outcomes such as excessive structural damage to barriers placed behind the curb, bar…

Road traffic crashes (RTCs) continue to be one of the top global killers, especially among children and young adults, and they require a data-driven approach to improve road safety. This study presents two novel algorithms: Babylon network kernel density estimation (BAB_NETKDE) and predicting safe routes for drivers i…

Conventional operator-based level crossing systems often cause long waiting times and unsafe driving behavior due to uniform barrier responses. This study introduces a speed-sensitive control system that adjusts barrier operation according to train velocity. Vibration sensors placed on the tracks detect train speed an…
