Consideration of a Pedestrian Speed Change Model in the Pedestrian-Vehicle Safety Assessment of Signalized Crosswalks
(
Elsevier B.V.
, 2017 , Conference Paper)
Pedestrian safety is one of the most challenging issues in the road network. Understanding the pedestrian maneuver is the key to applying countermeasures against traffic crashes. It is known that behaviors of pedestrians ...
An overview of pedestrian signal setting and implementation in the State of Qatar
(
Elsevier B.V.
, 2017 , Conference Paper)
Pedestrian signal control is a main influencing factor on the Level of Service of crossing facilities and on the safety performance considering conflicts with vehicles. In signal design, pedestrian clearance time is a key ...
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. ...
Blockchain technology for healthcare: Enhancing shared electronic health record interoperability and integrity
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
The Electronic Health Records (EHR) sharing system is the state of art for delivering healthcare. The tools within the system can predict outcomes during the patient's lifetime, monitor how effective are treatments, track ...
Towards commercialization of self-healing technology in epoxy coatings
(
National Assoc. of Corrosion Engineers International
, 2015 , Conference Paper)
This work is focused on developing viable self-healing coatings especially considering the viability of the coating in a commercial context. With this in mind, finding low cost healing agents, with satisfactory healing and ...
Effect of the length of silicon nano-dot/wire on band gap
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2014 , Conference Paper)
We will report on the role of the length of silicon nanowire (SNW) in determining the band gap of a structure. We find that the band gap decreases with SNW length for the same diameter and approaches the band gap for an ...
Oxygen passivation as effective technique for tailoring the nature of band gap of silicon nanowires
(
Institute of Electrical and Electronics Engineers Inc. (IEEE)
, 2015 , Conference Paper)
Silicon nanowires have been subjected to several experiential and theoretical studies, including chemical tuning with different substituents aiming to tailor the band gap as well as increasing optical absorption efficiency ...
Degraded Arid Soil Reclamation for Cotton Cultivation Using Organic Waste Amendments
(2024 , Conference Paper)
Qatar is one of the most fertilizer-dependent countries due to challenging soil and climatic conditions. The country strives toward self-sufficiency in agricultural production in alignment with the Qatar National Vision ...
