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 ...
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 ...
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. ...
Do detection-based warning strategies improve vehicle yielding behavior at uncontrolled midblock crosswalks?
(
Elsevier Ltd
, 2021 , Article)
Pedestrians being the most vulnerable road users account for a large proportion of injuries and fatalities from road traffic crashes. Pedestrians are involved in around one-third of the whole fatalities coming from the ...
Improved traffic safety at work zones through animation-based variable message signs
(
Elsevier Ltd
, 2021 , Article)
Work zones are established to provide a safe environment for all road users and road workers. However, based on the statistics, they can be considered as crash prone zones due to changes in the road alignments and the ...
Autonomous vehicles between anticipation and apprehension: Investigations through safety and security perceptions
(
Elsevier Ltd
, 2021 , Article)
Due to the ongoing enormous infrastructural developments and car ownership culture in Qatar, it could be one of those countries to introduce Autonomous Vehicles (AV) technology at the early stages. Therefore, this study ...
Sandstorm animations on rural expressways: The impact of variable message sign strategies on driver behavior in low visibility conditions
(
Elsevier Ltd
, 2021 , Article)
Problem: Evolving sandstorms on rural expressways in desert countries impair drivers' contrast vision and increase the risk of serious crashes due to delayed speed adjustments. Intelligent Transport Systems (ITS) such as ...
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 ...
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 ...
