Effectiveness of Consistency Measures in Crash Prediction Models for Two-Lane Highways in Palestine
( Springer Verlag , 2018 , Article)Crash prediction models (CPMs) are important tools to predict the safety performance of highways based on their operational and geometric characteristics. Most of these models use geometric design characteristics to predict ... -
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 ... -
Ridge penalization-based generalized linear model (GzLM) for predicting risky-driving index
( IEOM Society , 2018 , Conference Paper)Road traffic crashes remain one of the major causes of preventable death and injury worldwide. Human behavior is considered one of the main factors leading to such tragic losses. In this paper, we analyze the responses of ... -
The performance assessment for the dMEWMA in capturing changes in simple linear profiles
( IEOM Society , 2018 , Conference Paper)In traditional quality control, the quality of product is typically modeled as the univariate or multivariate distribution of the quality parameters. In more recent applications, the quality is modeled using the relationship ... -
Numerical and experimental investigation on corrugation geometry for metallic tubes under lateral loading
( Trans Tech Publications Ltd , 2018 , Conference Paper)Energy absorption devices are being used to protect structures from severe damages and reduce injury to occupants during accidents. The integrated characteristics of crash absorption devices can be classified as high energy ... -
Drivers� crossing behaviour between express and local lanes with soft separation: A driving simulator study
( Gioacchino Onorati Editore , 2018 , Article)In different countries, hard separation is adopted as a technique to separate express and local lanes. However, in case of an incident, especially on the express lane, traffic jams can occur as there is no escape route. ... -
The impact of perceptual countermeasures on driving behavior in rural-urban transition road segments: A driving simulator study
( Gioacchino Onorati Editore , 2018 , Article)This driving simulator study investigated the impact of perceptual countermeasures on driving behavior by creating perceptual effects via pavement markings. Two different marking schemes (i.e. Optical Circles and Optical ... -
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 ... -
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 ... -
Effectiveness of Driver Simulator as a Driving Education Tool
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)The impact and validity of driving simulators as an educational tool in driving schools in the licensing process remains questioned in literature. Many driving schools utilize driving simulators as a tool to assist students ... -
Variable message sign strategies for congestion warning on motorways - A driving simulator study
( Gioacchino Onorati Editore , 2018 , Article)Congestion and stopped traffic on motorways constitute a potential safety hazard for drivers. In particular, unexpected hard congestion tails are the causes of serious rear-end crashes as they compromise the drivers' ability ... -
Analysis of illegal pedestrian crossing behavior on a major divided arterial road
( Elsevier Ltd , 2018 , Article)Pedestrians’ illegal mid-block crossing increases the chances of a crash compared to crossing at marked or signalized crosswalks. Therefore, it is necessary to have an accurate understanding of this type of behavior to be ... -
Well-to-wheel water footprints of conventional versus electric vehicles in the United States: A state-based comparative analysis
( Elsevier Ltd , 2018 , Article)Today, increasing levels of water demand become a particularly serious challenge for many countries, especially since water is an essential element for production of transportation fuels. Unfortunately, no research efforts ... -
