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, ...
Traffic safety culture of professional drivers in the State of Qatar
(
Elsevier B.V.
, 2019 , Article)
Professional drivers play a significant role within the traffic system of the State of Qatar. With developing infrastructure, the need for professional drivers is growing. However, knowledge is lacking about their perception ...
Pedestrian flow characteristics through different angled bends: Exploring the spatial variation of velocity
(
Public Library of Science (PLOS)
, 2022 , Article)
Common geometrical layouts could potentially be bottlenecks, particularly during emergency and high density situations. When pedestrians are interacting with such complex geometrical settings, the congestion effect might ...
Analysis of Stopping Sight Distance (SSD) Parameters: A Review Study
(
Elsevier B.V.
, 2022 , Article)
Stopping sight distance (SSD) is one of the important elements in geometric highway design, which relies on the two key parameters, i.e., vehicle braking characteristics and drivers' reaction time. Previous studies have ...
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 ...
