( Qatar Univesrity Press , 2020 , Conference Paper)"Large crowds can be expected at famous tourist attractions, e.g., Souq Waqif, during special events such as the FIFA World Cup 2022. A comprehensive understanding of crowd dynamics is extremely important in order to ... -
Data-Driven Optimization for Dynamic Shortest Path Problem Considering Traffic Safety
( IEEE , 2022 , Article)Traffic congestion is an inescapable problem that frustrates drivers in megacities. Although there is hardly a way to eliminate the congestion, it is possible to mitigate the impact through predictive methods. This paper ... -
Defensive or competitive Autonomous Vehicles: Which one interacts safely and efficiently with pedestrians?
( Elsevier , 2022 , Article)The emergence of Autonomous Vehicles (AVs) could provoke unexpected challenges in urban traffic environments. One such crucial challenge is the conflicts between pedestrians and AVs, particularly on unsignalized mid-block ... -
Delay or travel time information? The impact of advanced traveler information systems on drivers’ behavior before freeway work zones
( Elsevier , 2022 , Article)Peak travel times contribute to congestion formation at freeway work zones. Advanced Traveler Information Systems (ATIS) can inform drivers in real-time about the delays and travel times en-route and can provide information ... -
Development of a risk assessment tool based on driver behavior and environment
( Intelligent Transport Systems (ITS) , 2014 , Conference Paper)Driver error is the leading cause of vehicle crashes; roadway segment characteristics and environmental conditions follow. However, no safety prediction model has been introduced to estimate risk associated with driver ... -
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 ... -
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 ... -
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 ... -
