Analysis of Stopping Sight Distance (SSD) Parameters: A Review Study
( Elsevier B.V. , 2022 , Article)Stopping sight distance (SSD) is one of the important elements in geometric highway design, which relies on the two key parameters, i.e., vehicle braking characteristics and drivers' reaction time. Previous studies have ... -
Promoting cycling activities in the State of Qatar: Challenges and potential treatments
( Elsevier B.V. , 2022 , Article)In the last few decades, cycling has received an increased attention due to its health, social, and economical benefits. Many countries are adopting different policies to encourage cycling as a daily mode of transport. In ... -
Driving behavior classification at signalized intersections using vehicle kinematics: Application of unsupervised machine learning
( Taylor & Francis , 2022 , Article)Driving behavior is considered as a unique driving habit of each driver and has a significant impact on road safety. This study proposed a novel data-driven Machine Learning framework that can classify driving behavior at ... -
Examining the role of road safety audits worldwide: exploring road safety expert’s opinions
( Taylor & Francis , 2022 , Article)Road safety audit (RSA) is a method used to proactively identify safety risks in road projects from planning, design, and construction stages. The effectiveness of the implementation of RSAs varies across the globe. This ... -
Investigating the impact of a novel active gap metering signalization strategy on driver behavior at highway merging sections
( Elsevier Ltd , 2021 , Article)A safe headway to the lead vehicle is important to reduce conflicts with merging vehicles from highway on-ramps. Previous research has outlined the advantage of gap metering strategies to yield sufficient space to merging ... -
A study on the determinants of Ethiopian minibus taxi drivers' speeding behaviour: An application of the 'major theorists' model
( Elsevier B.V. , 2022 , Article)Speeding is the most common road safety problem that results in many traffic accidents in Addis Ababa, Ethiopia. Minibus taxis substantially contribute to speed-related road traffic crashes in Addis Ababa. This study aimed ... -
Using driving simulator to study the effect of crash fact signs on speeding behaviour along freeways
( Taylor & Francis , 2022 , Article)A driving simulator study was utilized to evaluate a potential countermeasure for speeding behaviour in order to reduce speed spillover. The behaviour of 56 subjects was observed. Participants drove a freeway for 5300 ... -
Experiences with licensing by autistic drivers: An exploratory study
( Elsevier B.V. , 2022 , Article)Autistic individuals obtain their driver's licenses significantly less or significantly later than non-autistic peers. In the past, research has been done on what problems autistic individuals experience when (learning to) ... -
The impact of rural expressway environments: drivers’ attention allocation to variable message signs
