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 ...
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 ...
Modelling speed behaviour in rural highways: Safety analysis of driving under adverse road-weather conditions
(
PLOS
, 2021 , Article)
This study proposes a methodical approach to model desired speed distributions under different road-weather and traffic conditions followed by identification of road-weather conditions with potentially higher safety risks ...
Analysis of gap parameters for the estimation of single lane roundabouts' capacity in the State of Qatar
(
Elsevier B.V.
, 2021 , Conference Paper)
Entry capacity is an important parameter for evaluating the roundabout performance. In general, entry capacity is influenced by three gap parameters: critical gap, follow-up time and minimum headway of circulating vehicles. ...
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 ...
Are Professional Drivers more Aggressive than General Drivers? A Case Study from Doha, Qatar
(
Elsevier B.V.
, 2022 , Conference Paper)
Previous studies have revealed that aggressive and reckless driving can largely affect the occurrence and severity of road crashes. There could be intentional aggressive and unsafe acts, which could significantly affect ...
Impact of COVID-19 Pandemic on Qatar Electricity Demand and Load Forecasting: Preparedness of Distribution Networks for Emerging Situations
(
MDPI
, 2022 , Article)
The COVID-19 pandemic has brought several global challenges, one of which is meeting the electricity demand. Millions of people are confined to their homes, in each of which a reliable electricity supply is needed, to ...
Planning and Optimizing Electric-Vehicle Charging Infrastructure Through System Dynamics
(
IEEE
, 2022 , Article)
One of the key solutions to address the issue of energy efficiency and sustainable mobility is to integrate plug-in electric vehicle (EV) infrastructure and photovoltaic (PV) systems. The research proposes a comprehensive ...
Road Crossing at Unmarked Mid-Block Locations: Exploring Pedestrians’ Perception and Behavior
(
Springer
, 2022 , Article)
Violations, risky behaviors and perceptions may largely contribute to crashes involving pedestrians, particularly at unmarked mid-block locations. The likelihood and severity of crashes at mid-block locations are higher ...
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 ...
