Safety performance of school buses in the State of Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2015 , Article)School buses and minibuses are one of the major modes of traveling for students in the state of Qatar. Many studies pointed to the fact that school buses travelling are safer for students than walking or car riding (Bolte, ... -
Joint replenishment model for multiple products with substitution
( Elsevier Inc. , 2016 , Article)We extend the classical economic order quantity model to address the joint replenishment of multiple products under substitution. The proposed model optimizes ordering quantities for each product under substitution effects ... -
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 ... -
Regional Well-to-Wheel Carbon, Energy, and Water Footprint Analysis of Electric Vehicles
( Atlantis Press , 2018 , Conference Paper)Adoption of alternative vehicle technologies such as electric vehicles (EVs), plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs) have the potential of reducing some of the environmental impacts ... -
Magnetorheological damper with external excitation for more efficient control of vehicles? dynamics
( SAGE Publications Ltd , 2018 , Article)This article presents a new concept design for magnetorheological dampers, where the excitation circuit and magnetic field are applied from outside the magnetorheological chamber. This magnetorheological damper was designed ... -
Evaluating the effect of seasonal variations on walking behaviour in a hot weather country using logistic regression
( Routledge , 2018 , Article)The city of Doha, Qatar experiences a hot and arid weather throughout the year. This study investigates the effect of season, type of day, and time of day on the walking behaviour of pedestrians in these conditions using ... -
Attitudes towards road safety among pre-drivers: The case of Qatar
( IEOM Society , 2018 , Conference Paper)A preliminary study involving school students aged 12-18 years attempted to test whether there is difference in attitudes towards road safety between Arab and non-Arab respondents. The sampled participants were categorized ... -
Sustainability Performance Simulation of the U.S. Urban Mobility Policies
(2018 , Conference Paper)Heavy dependence on personal vehicle usage in the U.S. has made the transportation sector one of the greatest contributors to air pollutant emissions the associated human health concerns. The transportation mode choices ... -
A Real Case-Based Study Exploring Influence of Human Age and Gender on Drivers’ Behavior and Traffic Safety
( Springer Verlag , 2018 , Conference Paper)The demand for understanding the functional relationship between changes in traffic safety level and human-related factors has increased remarkably due to a steady increase in population and traffic volume. Motor vehicle ... -

( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)One of the most interesting new approaches in the transportation research field is the Naturalistic Driver Behavior which is intended to provide insight into driver behavior during everyday trips by recording details about ... -
A mini review on percent time-spent-following (PTSF) as the service measure for two-lane highways
( Komunitas Ilmuwan dan Profesional Muslim Indonesia , 2018 , Article)Percent Time Spent Following (PTSF) is used by the Highway Capacity Manual (HCM) as one of the service measures to assess the level-of-service of two-lane highways since the 2000 edition. But, the problem facing to estimate ... -
An integrated dynamical modeling perspective for infrastructure resilience
( MDPI , 2018 , Article)© 2018 by the authors This paper considers a dynamical way to connect resilience outcomes and processes by nesting process-based approaches inside a controlled dynamical system under resource constraints. To illustrate ... -
