Analysis of the Trajectories of Left-turning Vehicles at Signalized Intersections
( Elsevier B.V. , 2020 , Conference)Internationally, an annual number of more than a million fatalities are caused by road traffic crashes, with particularly signalized intersections being crash prone locations within the highway system. An accumulation of ... -
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 ... -
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 ... -
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) ... -
Impact of the geometric field of view on drivers’ speed perception and lateral position in driving simulators
( Elsevier , 2020 , Conference)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 Traffic Flow Efficiency during Yellow Interval at Signalized Intersections Using a Smart Countdown System
( Institute of Electrical and Electronics Engineers , 2022 , Article)Inadequate and unnecessary stopping at signalized intersections reduces operational efficiency. The study aims at investigating the effect of a smart advanced warning system on driving behavior and the efficiency of ... -
Investigating the attitudes of Egyptian drivers toward traffic safety
( Elsevier , 2022 , Article)One of the main pillars for improving road safety in any country is a good understanding of traffic safety culture and the driving behavior of local drivers. The primary aim of this study was to determine whether Egyptian ... -
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 ... -
Motorcyclists’ Safety on Expressways: Subjective and Objective Evaluations
( Springer Berlin Heidelberg , 2019 , Article)This study objectively and subjectively investigates the factors influencing motorcyclists’ safety on expressways. The relationships between motorcyclist stress while driving on expressways and potential influencing factors ... -
A multi-country survey for collecting and analyzing facts related to road traffic safety: Legislation, enforcement, and education for safer drivers
( Elsevier , 2022 , Article)Road traffic safety is a crucial global objective. It is important for every country to review and improve road safety policies and strategies, based on an objective understanding of its own road traffic safety situation ... -
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 ... -
Relating reactive and proactive aggression to trait driving anger in young and adult males: A pilot study using explicit and implicit measures
( MDPI , 2021 , Article)Driving anger and aggressive driving are main contributors to crashes, especially among young males. Trait driving anger is context-specific and unique from other forms of anger. It is necessary to understand the mechanisms ... -
Sandstorm animations on rural expressways: The impact of variable message sign strategies on driver behavior in low visibility conditions
( Elsevier Ltd , 2021 , Article)Problem: Evolving sandstorms on rural expressways in desert countries impair drivers' contrast vision and increase the risk of serious crashes due to delayed speed adjustments. Intelligent Transport Systems (ITS) such as ...
