A Real Case-Based Study Exploring Influence of Human Age and Gender on Drivers’ Behavior and Traffic Safety
Ghadban N.R.; Abdella G.M.; Al-Khalifa K.N.; Hamouda A.M.; Abdur-Rouf K.B. ( 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 ... -
An adaptive thresholding-based process variability monitoring
Abdella G.M.; Kim J.; Kim S.; Al-Khalifa K.N.; Jeong M.K.M.K.; Hamouda A.M.; Elsayed E.A.... more authors ... less authors ( Taylor and Francis Inc. , 2019 , Article)In high-dimensional processes, monitoring process variability is considerably difficult due to the large number of variables and the limited number of samples. Monitoring changes in the covariance matrix of a multivariate ... -
Analyzing the impact of human characteristics on the comprehensibility of road traffic signs
Ghadban N.R.; Abdella G.M.; Alhajyaseen W.; Al-Khalifa K.N. ( IEOM Society , 2018 , Conference Paper)Traffic safety is one of major challenges facing most communities worldwide. To improve traffic safety, regulating traffic movement through markings, signs, channelization, and others is essential. Traffic signs are used ... -
Attitudes towards road safety among pre-drivers: The case of Qatar
Mohammed S.O.; Al-Khalifa K.N.; Alhajyaseen W.K.M.; Abounada S.A.; Ahmed M.H. ( 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 ... -

Bayesian framework for fault variable identification
Turkoz M.; Kim S.; Jeong Y.-S.; Jeong M.K.; Elsayed E.A.; Al-Khalifa K.N.; Hamouda A.M.... more authors ... less authors ( Taylor and Francis Inc. , 2019 , Article)In most manufacturing processes, identifying the faulty process variables that may lead to process changes is crucial for quality engineers and practitioners. There are several parametric procedures for identifying faulty ... -
Control charts for variability monitoring in high-dimensional processes
Kim J.; Abdella G.M.; Kim S.; Al-Khalifa K.N.; Hamouda A.M. ( Elsevier Ltd , 2019 , Article)Monitoring process variability is associated with detecting changes in the covariance matrix of a multivariate normal process. Most monitoring methods estimate the sample covariance matrix and compare it with the in-control ... -
Optimizing national resource usage through the integration of University shuttle service with the public rail: The case study in Qatar University
Al-Hammadi A.A.; Albaker A.A.; Al-Fakhroo J.A.; Abdella G.M.; Al-Khalifa K.N. ( IEOM Society , 2018 , Conference Paper)Qatar University is the largest public educational institution in the State of Qatar. The university community has diverse committed faculty who not only teaching but also conducting research studies contributing actively ... -
Penalized Conway-Maxwell-Poisson regression for modelling dispersed discrete data: The case study of motor vehicle crash frequency
Abdella G.M.; Kim J.; Al-Khalifa K.N.; Hamouda A.M. ( Elsevier B.V. , 2019 , Article)Statistical modelling of road crashes has been of extreme interest to researchers over the last decades. Such models are necessary for the investigation of the opportunities for road safety improvement. The motor vehicle ... -
Ridge penalization-based generalized linear model (GzLM) for predicting risky-driving index
Rouf K.B.A.; Abdella G.M.; Al-Khalifa K.N.; Alhajyaseen W. ( 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
Abdella G.M.; Hamouda A.S.; Al-Khalifa K.N. ( 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 ... -
Usage of Non-Linear Regression for Modeling the Behavior of Motor Vehicle Crash Fatality (MVF) Rate
Abdella G.M.; Alhajyaseen W.; Al-Khalifa K.N.; Hamouda A.M. ( IEOM Society , 2017 , Conference Paper)Data analysis for vehicular crash counts is essential for transportation and traffic management systems (TTMS) to develop practical and innovative road safety interventions. The crash trend analysis, in particular, is the ...
