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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
Effect of U-turns and heavy vehicles on the saturation flow rates of left-turn lanes at signalized intersections
(
MDPI
, 2020 , Article)
© 2020 by the authors. The Saturation Flow Rate (SFR) is a primary measure that can be used when estimating intersection capacity. Further, the efficiency of signal control parameters also depends on the accuracy of assumed ...
Changes in Driving Behavior Across Age Cohorts in an Arab Culture: The Case of State of Qatar
(
Elsevier B.V.
, 2018 , Conference Paper)
In this investigation, we aimed to examine the structure of the Driving Behavior Questionnaire (DBQ) across age cohorts spanning 14 to 55 years in the State of Qatar. In addition, we aimed to examine variations in driving ...
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) ...
