A reliability-based weather-responsive variable speed limit system to improve the safety of rural highways
( Elsevier , 2022 , Article)Weather-responsive Variable Speed Limit (WRVSL) systems treat speed limits as weather-dependent random variables, as opposed to the conventional static speed limits. This study (i) evaluates drivers’ response to a fixed ... -
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 ... -
Safe Route Mapping of Roadways Using Multiple Sourced Data
( Institute of Electrical and Electronics Engineers , 2022 , Article)The use of systematic techniques with historical crash data and qualitative measures has long been a common practice to identify the problematic road features and develop countermeasures to mitigate the crash risk in ... -
ANN-Based traffic volume prediction models in response to COVID-19 imposed measures
( Elsevier , 2022 , Article)Many countries around the globe have imposed several response measures to suppress the rapid spread of the COVID-19 pandemic since the beginning of 2020. These measures have impacted routine daily activities, along with ... -
The Assessment of Pedestrian-Vehicle Conflicts at Crosswalks Considering Sudden Pedestrian Speed Change Events
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Introduction: Pedestrians are vulnerable road users. In Japan, more than one-third of the fatalities in traffic crashes are pedestrians and most accidents occur as the pedestrians cross a road. To evaluate alternative ... -
Variable Message Sign strategies for Congestion Warning on Motorways
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Introduction Motorways are the safest roads by design and regulation. Still, motorways in the European Union accounted for nearly 27,500 fatalities from 2004 to 2013 (Adminaite, Allsop, & Jost, 2015). The likelihood ... -
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 ... -
Investigating the impact of innovative treatments on driving behavior at school bus stops: A driving simulator study
( Qatar University Press , 2021 , Poster)The illegal overtaking/crossing of stopped school buses has been identified as one of the leading causes of students' injuries and fatalities. The likelihood of students in getting involved in a school bus-related crash ... -
Impact of Attention Deficit Hyperactivity Disorder on Driving among Drivers in Qatar
( Qatar University Press , 2021 , Poster)This study aims to investigate the impact of ADHD traits on young drivers' deviant driving behaviors that may contribute to their involvement in traffic crashes. Methods: A sample of 450 young drivers from the State of ... -
Enhancing Pedestrian Safety through the Development of Advanced Operational Strategies for Crosswalks in Residential Areas
( Qatar University Press , 2021 , Poster)Pedestrians are the most vulnerable group in the traffic. Every year approximately 40,000 pedestrians are killed in the world due to road traffic crashes. In the state of Qatar, the situations are even worse with around ... -
Performance Evaluation of Vehicle Restraint Systems in the Context of Design and Installation
(2021 , Article)Vehicle Restraint Systems (VRS), a necessary component of the road design, are widely implemented by transport authorities to protect vehicles from severe incidents, mainly colliding to the roadside as well as median ... -
Modeling the Impact of Downstream Conditions on Discharging Behavior of Vehicles at Signalized Intersections Using Micro-Simulation
( Springer , 2020 , Article)© 2020, King Fahd University of Petroleum & Minerals. In areas where traffic demand is high and intersections are closely spaced, the drivers’ desire for quick discharge is demotivated by negative downstream conditions, ... -
Innovative countermeasures for red light running prevention at signalized intersections: A driving simulator study
( Elsevier , 2020 , Article)The change interval, which includes the yellow and all-red times, plays a crucial role in the safety and operation of signalized intersections. During this interval, drivers not only need to decide to stop or go but also ... -
Optical pavement treatments and their impact on speed and lateral position at transition zones: A driving simulator study
( Elsevier , 2021 , Article)Transition zones are a road section where posted speed drops from higher to lower limits. Due to the sudden changes in posted speed limits and road environment, drivers usually do not adapt to the posted speed limits and ... -
Throughput optimization for the Robotic Cell Problem with Controllable Processing Times
( EDP Sciences , 2017 , Article)In this paper, we present a MIP-based heuristic and an effective genetic algorithm for the Robotic Cell Problem with Controllable Processing Times (RCPCPT). This problem arises in modern automated manufacturing systems and ... -
Seat belt and child restraint systems : ESRA2 Thematic report No. 8
