Autonomous vehicles between anticipation and apprehension: Investigations through safety and security perceptions
(
Elsevier Ltd.
, 2021 , Article)
Due to the ongoing enormous infrastructural developments and car ownership culture in Qatar, it could be one of those countries to introduce Autonomous Vehicles (AV) technology at the early stages. Therefore, this study ...
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 ...
Analysis of the Trajectories of Left-turning Vehicles at Signalized Intersections
(
Elsevier B.V.
, 2020 , Conference Paper)
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 ...
Quantifying the impact of COVID–19 preventive measures on traffic in the State of Qatar
(
Elsevier
, 2021 , Article)
Ever since the beginning of 2020, the mobility of people and goods all over the world has been extremely limited as a result of movement restrictions imposed by local authorities as part of several other efforts to stop ...
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 ...
Performance of Seawater-Mixed Recycled-Aggregate Concrete
(
American Society of Civil Engineers (ASCE)
, 2020 , Article)
The use of seawater and recycled coarse aggregate (RCA) in concrete mixtures leads to the production of a very sustainable concrete. The potential risk of steel reinforcement corrosion (due to chloride in the seawater) in ...
Fractional factorial design model for seismic performance of RC bridge piers retrofitted with steel-reinforced polymer composites
(
Elsevier
, 2020 , Article)
This study explores the effects of key design parameters on the performance of seismically deficient rectangular cross-section reinforced concrete (RC) bridge piers strengthened with steel-reinforced polymer (SRP) composites. ...
Shear span-to-depth ratio effect on steel reinforced grout strengthened reinforced concrete beams
(
Elsevier
, 2020 , Article)
The effect of the shear span-to-depth (a/d) ratio on the shear behavior of steel reinforced grout (SRG)-strengthened reinforced concrete (RC) beams is experimentally investigated. Four critical shear spans corresponding ...
Shear strengthening of reinforced concrete deep beams using near-surface mounted hybrid carbon/glass fibre reinforced polymer strips
(
Elsevier
, 2020 , Article)
This study investigated the efficacy of near surface mounted (NSM) hybrid carbon/glass fibre reinforced polymer (FRP) strips for strengthening of shear-deficient reinforced-concrete (RC) rectangular deep beams. A specific ...
Plastic hinge length of rectangular RC columns using ensemble machine learning model
(
Elsevier
, 2021 , Article)
It is critical to properly define the plastic hinge region (the region that is exposed to maximum plastic deformation) of reinforced concrete (RC) columns to assess their performances in terms of ductility and energy ...
