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 ... -
An assessment tool to evaluate complete streets in developing countries: The case of Qatar
( Inderscience Enterprises Ltd. , 2018 , Article)Complete streets refer to a simple and effective transportation policy to improve traffic safety and comfort for all users within urban areas. Car dependency is a major concern in developing countries. Endorsing complete ... -
Analyzing the impact of human characteristics on the comprehensibility of road traffic signs
( IEOM Society , 2018 , Conference)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 ... -
Ridge penalization-based generalized linear model (GzLM) for predicting risky-driving index
( IEOM Society , 2018 , Conference)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)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 ... -
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 ... -
Motorcyclists’ Safety on Expressways: Subjective and Objective Evaluations
( Springer Berlin Heidelberg , 2019 , Article)This study objectively and subjectively investigates the factors influencing motorcyclists’ safety on expressways. The relationships between motorcyclist stress while driving on expressways and potential influencing factors ... -
Pedestrians' Speed Analysis at Signalized Crosswalks
( Elsevier B.V. , 2018 , Conference)Pedestrian speed is essential for designing signal timings as well as for understanding pedestrian safety issues. This paper presents analysis of three types of pedestrian speeds (entry speed, crossing speed, and exit ... -
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 ... -
Traffic safety culture of professional drivers in the State of Qatar
( Elsevier B.V. , 2019 , Article)Professional drivers play a significant role within the traffic system of the State of Qatar. With developing infrastructure, the need for professional drivers is growing. However, knowledge is lacking about their perception ... -
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. ... -
Real-time Driver Drowsiness Detection for Android Application Using Deep Neural Networks Techniques
( Elsevier B.V. , 2018 , Conference)Road crashes and related forms of accidents are a common cause of injury and death among the human population. According to 2015 data from the World Health Organization, road traffic injuries resulted in approximately 1.25 ... -
