Investigation of Weather Impacts on Pedestrian Volumes
(
Elsevier B.V.
, 2016 , Conference Paper)
This study investigates the impacts of temporal and weather characteristics on pedestrian volumes in a hot climate condition. A major neighborhood located in an urban area in Doha, Qatar was chosen as a case study site. ...
Literature Review of Advancements in Adaptive Ramp Metering
(
Elsevier
, 2016 , Conference Paper)
Over a period spanning more than 30 years, several ramp metering algorithms have been developed to improve the operation of freeways. Many of these algorithms were deployed in several regions of the world, and field ...
Time Delay and Cost Overrun in Qatari Public Construction Projects
(
Elsevier Ltd
, 2016 , Conference Paper)
This paper investigated cost overruns and delays in Qatari public construction projects. An extensive review of regional and international publications was conducted to get a better understanding of the problem and the ...
Comparison of SimTraffic and VISSIM Microscopic Traffic Simulation Tools in Modeling Roundabouts
(
Elsevier B.V.
, 2015 , Conference Paper)
Abstract SimTraffic and VISSIM are two microscopic traffic simulation tools that are capable of modeling arterial roads with signalized intersections and roundabouts. This study compares the performance of the two simulation ...
Numerical study on settlement of piled foundations on homogenous rock
(
Taylor and Francis
, 2014 , Conference Paper)
Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ...
Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ...
Geotechnical considerations on the design of piled rafts on rock
(
Research Publishing Services
, 2011 , Conference Paper)
This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ...
