Enhancing Pedestrian Safety through the Development of Advanced Operational Strategies for Crosswalks in Residential Areas
(
Qatar University Press
, 2021 , Poster)
Pedestrians are the most vulnerable group in the traffic. Every year approximately 40,000 pedestrians are killed in the world due to road traffic crashes. In the state of Qatar, the situations are even worse with around ...
Investigating the impact of innovative treatments on driving behavior at school bus stops: A driving simulator study
(
Qatar University Press
, 2021 , Poster)
The illegal overtaking/crossing of stopped school buses has been identified as one of the leading causes of students' injuries and fatalities. The likelihood of students in getting involved in a school bus-related crash ...
Delay or travel time information? The impact of advanced traveler information systems on drivers’ behavior before freeway work zones
(
Elsevier
, 2022 , Article)
Peak travel times contribute to congestion formation at freeway work zones. Advanced Traveler Information Systems (ATIS) can inform drivers in real-time about the delays and travel times en-route and can provide information ...
Road safety status during COVID-19 pandemic: exploring public and road safety expert’s opinions
(
Taylor & Francis
, 2022 , Article)
The main objective of this study is to investigate the status of traffic safety and the public perception of traffic safety during the during COVID-19 pandemic. Three different data sets are used in this study: road crash ...
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 ...
Dynamic travel information strategies in advance traveler information systems and their effect on route choices along highways
(
Elsevier
, 2020 , Article)
Advance Traveler Information Systems (ATIS) inform drivers about traffic incidences and expected travel times/ delays en-route. An online computer study was conducted in Qatar to investigate drivers' willingness ...
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. ...
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, ...
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 ...
