Experimental analysis of additively manufactured thin-walled heat-treated circular tubes with slits using AlSi10Mg alloy by quasi-static axial crushing test
(
Elsevier Ltd
, 2019 , Article)
In this study, additively manufactured aluminum thin-walled tubes with different slit dimensions are proposed to improve energy absorption efficiency. A total of 18 samples, which varied in the number of slits, slit length, ...
Using the theory of planned behavior to predict the use of an upcoming public transportation service in Qatar
(
Elsevier Ltd
, 2019 , Article)
Public transportation systems play a major role in accommodating public travel needs. To accommodate the need for public transportation in Qatar, a metro network is currently under construction. However, commuters have ...
Temporal variation in walking behavior: An empirical study
(
Elsevier Ltd
, 2017 , Article)
This study provides a baseline for understanding the variation in walking behavior with respect to seasonal conditions in a hot weather country in the Arabian Gulf region. A busy neighborhood with different land-use patterns ...
The relationship between impact speed and the probability of pedestrian fatality during a vehicle-pedestrian crash: A systematic review and meta-analysis
(
Elsevier Ltd
, 2019 , Article)
Background
Pedestrians struck in motorised vehicle crashes constitute the largest group of traffic fatalities worldwide. Excessive speed is the primary contributory factor in such crashes. The relationship between estimated ...
Modeling pedestrian crossing speed profiles considering speed change behavior for the safety assessment of signalized intersections
(
Elsevier Ltd
, 2017 , Article)
Pedestrian safety is one of the most challenging issues in road networks. Understanding how pedestrians maneuver across an intersection is the key to applying countermeasures against traffic crashes. It is known that the ...
The effectiveness of applying dynamic lane assignment at all approaches of signalized intersection
(
Elsevier Ltd
, 2017 , Article)
Existing traffic control strategies at signalized intersections aim at the optimization of signal timing parameters while assuming fixed lane assignments to the movements at each approach. Such control results in the waste ...
Underlying Mechanisms of Transit-Oriented Development: A Conceptual System Dynamics Model in Qatar
(
MDPI
, 2022 , Article)
Transit-Oriented Development (TOD) is an urban planning approach that facilitates the achievement of sustainable development goals from an urban planning and transportation perspective. Developed countries are moving rapidly ...
Aerial ropeway system - feasibility study in Doha, Qatar
(
Canadian Science Publishing
, 2021 , Article)
Aerial ropeway systems, also called gondolas and aerial cable cars, are amongst driverless transportation modes, which are progressively drawing the attention in promoting tourism. Aerial ropeway systems have been operated ...
Improved Traffic Flow Efficiency during Yellow Interval at Signalized Intersections Using a Smart Countdown System
(
Institute of Electrical and Electronics Engineers
, 2022 , Article)
Inadequate and unnecessary stopping at signalized intersections reduces operational efficiency. The study aims at investigating the effect of a smart advanced warning system on driving behavior and the efficiency of ...
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 ...
