The appraisal of roadway environment and infrastructure by drivers with autism: A qualitative study
( Elsevier Ltd. , 2021 , Article)People with an autism spectrum disorder (ASD) might experience difficulties while driving, for instance, related to hazard perception. These difficulties may be related to cognitive issues (internal) such as attention-shifting, ... -
Autism-friendly public bus transport: A personal experience–based perspective
( SAGE , 2022 , Article)Community participation and the formation of social networks are crucial for a qualitative life. To this end, transportation plays an essential role. Many autistic people rely on public transportation for their mobility ... -
Concentration of pb, cu, zn and cd in the roadside soil of doha: Effect of traffic volume and season
( HARD , 2021 , Article)The concentration of copper (Cu), lead (Pb), zinc (Zn) and cadmium (Cd) in the roadside soil of Doha was evaluated. Three different roads were selected for the study namely, Mesrif street, Salwa road and Cornish street ... -
Crowd Evacuation through Crossing Configurations: Effect of Crossing Angles and Walking Speeds on Speed Variation and Evacuation Time
( Multidisciplinary Digital Publishing Institute (MDPI) , 2022 , Article)The design of safe and efficient pedestrian facilities necessitates the knowledge of complex human movements, such as intersecting pedestrian streams, under different conditions. This study aims to experimentally investigate ... -
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 Variable Message Sings Strategies for Traffic Management at Work Zones
(2020 , Master Thesis)Work zones are defined as road sections of which different activities such as road construction or maintenance take place. In most work zones, road alignments are different than the pre-work periods. Therefore, speed limits ... -
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 ... -
Effectiveness of the pedestrian detection strategies and pavement markings: A driving simulator study
( Qatar University Press , 2020 , Poster)Pedestrians are the most vulnerable group in the traffic and accounts for about 40,000 deaths each year worldwide. One of the main reasons is that drivers usually do not yield to pedestrian which creates serious conflicts ... -
Empirical evaluation of drivers’ start-up behavior at signalized intersection using driving simulator
( Elsevier , 2020 , Article)Start-up behavior at signalized intersection mainly depends on perception reaction time of drivers to the green phase. This study investigated the start-up behavior at signalized intersections by considering reaction time, ... -
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) ... -
Exploring Crowd Management and Evacuation Strategies using Microscopic Pedestrian Simulation: A Case Study of Souq Waqif
( Qatar University Press , 2023 , Conference Paper)Safe egress plans are critical for crowd evacuation at touristic attractions, particularly during special events, as visitors are often unaware of their options. Identification of bottlenecks in the walking spaces are vital ... -
Fuel consumption at signalized intersections: Investigating the impact of different signal indication settings
( Elsevier Ltd. , 2023 , Article)The fuel consumption of vehicles depends on various factors including vehicle design, driving style, traffic management, and road design. Many manufacturers have been developing efficient and smart vehicles, which contributes ... -
Human factors and road safety in the 2nd international traffic safety conference
( Taylor & Francis , 2023 , Other)This special issue presents selected articles submitted to the 2nd International Traffic Safety Conference 2023, Doha, (Qatar). More than 150 papers were submitted and they were peer-reviewed. Only 16 papers were highly ... -
Impact of Countdown ground LED lights on traffic flow efficiency at signalized intersections: a driving simulator study
( Qatar University Press , 2020 , Poster)Unnecessary stopping at signalized intersections during yellow interval reduces traffic flow efficiency. The aim of this driving simulator study was to investigate the impact of an advanced countdown system on traffic flow ... -
Impact of the geometric field of view on drivers’ speed perception and lateral position in driving simulators
( Elsevier , 2020 , Conference Paper)Driving simulators have become an effective tool in road safety research. In recent years, the validity of simulators raised debates concerning the extant to which driving in the simulator resembles driving in the reality. ... -
Improved Road Safety at Work Zones Using Advanced Traveler Information Systems
( Qatar University Press , 2020 , Poster)Work zones are road sections where road construction or maintenance activities take place. These work zones usually have different alignment and furniture than the original road and thus temporary lower speeds are adopted ...
