Sustainability Performance Simulation of the U.S. Urban Mobility Policies
(2018 , Conference)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 ... -
Attitudes towards road safety among pre-drivers: The case of Qatar
( IEOM Society , 2018 , Conference)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 ... -
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 ... -
A Real Case-Based Study Exploring Influence of Human Age and Gender on Drivers’ Behavior and Traffic Safety
( Springer Verlag , 2018 , Conference)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 ... -
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 ... -
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 ... -
