Do detection-based warning strategies improve vehicle yielding behavior at uncontrolled midblock crosswalks?
( Elsevier Ltd. , 2021 , Article)Pedestrians being the most vulnerable road users account for a large proportion of injuries and fatalities from road traffic crashes. Pedestrians are involved in around one-third of the whole fatalities coming from the ... -
Does Pedestrian Penalty Affect Pedestrian Behavior? A Case of State of Qatar
( Elsevier , 2021 , Article)Crashes involving pedestrians are a major concern for authorities in many developed and developing countries. To refrain pedestrians from illegal or unsafe road behavior, authorities introduced three pedestrian penalties ... -
Driver Drowsiness Detection Model Using Convolutional Neural Networks Techniques for Android Application
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)A sleepy driver is arguably much more dangerous on the road than the one who is speeding as he is a victim of microsleeps. Automotive researchers and manufacturers are trying to curb this problem with several technological ... -
Drivers' perceptions of smartphone applications for real-time route planning and distracted driving prevention
( Hindawi Limited , 2019 , Article)Given the increasing importance and availability of traffic-related smartphone applications, understanding their potential use is vital, especially in developing countries. This research explores motorist perceptions of ... -
Drivers’ estimation of their travelling speed: a study on an expressway and a local road
( Taylor and Francis Ltd. , 2019 , Article)Correctly estimating the travelling speed is essential for safety on the roads to ensure safer interactions with other drivers and to avoid violations of traffic regulations. Therefore, it is important to create understanding ... -
Drivers� crossing behaviour between express and local lanes with soft separation: A driving simulator study
( Gioacchino Onorati Editore , 2018 , Article)In different countries, hard separation is adopted as a technique to separate express and local lanes. However, in case of an incident, especially on the express lane, traffic jams can occur as there is no escape route. ... -
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 ... -
Driving simulation sickness and the sense of presence: Correlation and contributing factors
( Elsevier Ltd. , 2021 , Article)Driving simulators are useful and effective tools for conducting studies in the field of traffic safety. Simulation sickness (SS) and the sense of presence (SP) are two well-known factors that could affect the results of ... -
Dynamic travel information strategies in advance traveler information systems and their effect on route choices along highways
( Elsevier , 2020 , Article)Advance Traveler Information Systems (ATIS) inform drivers about traffic incidences and expected travel times/ delays en-route. An online computer study was conducted in Qatar to investigate drivers' willingness ... -
Eco-efficiency of electric vehicles in the United States: A life cycle assessment based principal component analysis
( Elsevier , 2019 , Article)This research presents an integrated sustainability assessment framework applied to electric vehicle technologies in the United States of America. Two methods; principal component analysis and life cycle assessment are ... -
Effect of ADHD traits in young drivers on self-reported deviant driving behaviours: An exploratory study in the Arab gulf region
( Elsevier , 2020 , Article)IntroductionAttention Deficit Hyperactivity Disorder (ADHD) can be defined in two key traits (inattention and hyperactivity-impulsivity), which can effect day-to-day capabilities such as driving performance. MethodsIn this ... -
Effect of U-turns and heavy vehicles on the saturation flow rates of left-turn lanes at signalized intersections
( MDPI , 2020 , Article)© 2020 by the authors. The Saturation Flow Rate (SFR) is a primary measure that can be used when estimating intersection capacity. Further, the efficiency of signal control parameters also depends on the accuracy of assumed ... -
Effectiveness of Consistency Measures in Crash Prediction Models for Two-Lane Highways in Palestine
( Springer Verlag , 2018 , Article)Crash prediction models (CPMs) are important tools to predict the safety performance of highways based on their operational and geometric characteristics. Most of these models use geometric design characteristics to predict ... -
Effectiveness of Driver Simulator as a Driving Education Tool
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)The impact and validity of driving simulators as an educational tool in driving schools in the licensing process remains questioned in literature. Many driving schools utilize driving simulators as a tool to assist students ... -
Effectiveness of Speed Limit Pavement Markings at Transition Zones Along Expressways
( IEEE , 2020 , Conference Paper)Transition zones are usually equipped with speed limit signs only. Drivers usually miss the speed limit information provided through the roadside signs and travel faster than the posted speed limit. This driving simulator ... -
