Energy absorption capabilities of complex thin walled structures
(
Institute of Physics Publishing
, 2017 , Conference Paper)
Thin walled structures have been used in the area of energy absorption during an event of a crash. A lot of work has been done on tubular structures. Due to limitation of manufacturing process, complex geometries were ...
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 ...
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 ...
Pedestrians' Speed Analysis at Signalized Crosswalks
(
Elsevier B.V.
, 2018 , Conference Paper)
Pedestrian speed is essential for designing signal timings as well as for understanding pedestrian safety issues. This paper presents analysis of three types of pedestrian speeds (entry speed, crossing speed, and exit ...
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. ...
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 ...
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 ...
Variable Message Sign strategies for Congestion Warning on Motorways
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
Introduction Motorways are the safest roads by design and regulation. Still, motorways in the European Union accounted for nearly 27,500 fatalities from 2004 to 2013 (Adminaite, Allsop, & Jost, 2015). The likelihood ...
