Exploring driver behaviors during tailgating situations: a driving simulator study
( Elsevier , 2023 , Conference)The characteristics of drivers vary from one individual to another and one culture to another, leading to distinct driving behaviors exhibited by different drivers. This study aims to explore drivers’ car-following behaviors ... -
Safety assessment of on-road cycling lanes: A comparative study of different layouts using driving simulator
( Elsevier , 2024 , Article)Over the past few decades, a growing attention has been directed toward cycling due to its positive impacts on social, economic, and health aspects. Various countries are adopting and implementing strategies to promote ... -
Modeling the Impact of Weather Conditions on Pedestrian Injury Counts Using LASSO-Based Poisson Model
( Springer Science and Business Media Deutschland GmbH , 2021 , Article)Statistical models for measuring the impact of adverse weather conditions on pedestrian injuries are of great importance for enhancing road safety measures. The development of these models in the presence of high collinearity ... -
Macro-scale direct shear test device for assessing soil-solid interface friction under low effective normal stresses
( ASTM International , 2014 , Article)The paper describes a new macro-scale direct shear test device for assessing the largedisplacement soil/solid interface drained shear strength at low effective normal stresses. The testing method arises from a need to ... -
Bearing Capacity and Settlement of Skirted Shallow Foundations on Sand
( American Society of Civil Engineers (ASCE) , 2013 , Article)The behavior of axially loaded skirted shallow foundations resting on sand was studied using an extensive numerical analysis. Surface, pier, and skirted square foundations resting on sand with different shear strength ... -
Shear strength of geosynthetic composite systems for design of landfill liner and cover slopes
( Elsevier , 2011 , Article)Torsional ring shear tests were performed on composite specimens that simulate the field alignment of municipal solid waste (MSW) landfill liner and cover system components. Simultaneous shearing was provided to each test ... -
A technique for estimating permeability of a randomly fractured rock mass
( Springer Verlag , 2007 , Article)Extensive field and laboratory testing programs were performed to develop a relationship between the permeability of a fractured limestone and the core recovery values. The studied limestone does not encompass any jointing ... -
Settlement of axially loaded piles entirely embedded in rock - analytical and experimental study
( Taylor and Francis , 2012 , Article)Finite element analysis was performed to study the settlement behaviour of axially loaded piles entirely embedded in nonhomogenous rock. The elastic modulus of the rock mass was taken to increase linearly along the pile ... -
Factors influencing determination of shale classification indices and their correlation to mechanical properties
( Springer Verlag , 2006 , Article)The influence of sample preparation procedure on the measured classification indices such as clay-size fraction, liquid limit, and plastic limit of shales was investigated. Shale samples covering a wide range of composition ... -
Two- and three-dimensional analyses of translational slides in soils with nonlinear failure envelopes
( Canadian Science Publishing , 2010 , Article)This paper aims to assess the effect of nonlinearity of the soil shear strength envelope on the sliding mass con-figurations and the minimum two- and three-dimensional factors of safety for slopes susceptible to translational ... -
Comparative study on the behavior of square foundations resting on confined sand
( Canadian Science Publishing , 2009 , Article)The behavior of shallow foundations resting on laterally and (or) vertically confined sand has been investigated using physical and numerical modeling. The models were designed to simulate the frequently constructed raft ... -
Stability analysis and charts for slopes susceptible to translational failure
( Canadian Science Publishing , 2006 , Article)The aim of this paper is to develop two- and three-dimensional stability charts for slopes susceptible to translational failure. An extensive parametric study was conducted using a slope model that is designed to simulate ... -
Geotechnical considerations on the design of piled rafts on rock
( Research Publishing Services , 2011 , Conference)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 ... -
Numerical study on settlement of piled foundations on homogenous rock
( Taylor and Francis , 2014 , Conference)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)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 ... -
Simple Procedure for Preliminary Estimation of the Permeability of Randomly Fractured Rock Masses
( American Society of Civil Engineers (ASCE) , 2024 , Article)A data-driven approach is used to show the significant discrepancy between the coefficients of permeability that are estimated through packer field tests and those back-calculated from the actual discharge pumped out of ... -
Undrained interface shear strength of fine-grained soils for near-shore marine pipelines
( ASTM International , 2020 , Article)The peak and residual interface shear strengths for a variety of normally consolidated soils were measured using a torsional ring shear apparatus modified to suit soil and interface testing under the undrained condition, ... -
Fully softened shear strength for soil slope stability analyses
( American Society of Civil Engineers (ASCE) , 2017 , Article)The fully softened shear strengths of soils, mudstones, and shales of different plasticities and gradations were measured at low (10 and 25 kPa), intermediate (50 and 100 kPa), and high (200, 300, and 400 kPa) effective ... -
