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 ... -
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 ... -
Changes in Driving Behavior Across Age Cohorts in an Arab Culture: The Case of State of Qatar
( Elsevier B.V. , 2018 , Conference)In this investigation, we aimed to examine the structure of the Driving Behavior Questionnaire (DBQ) across age cohorts spanning 14 to 55 years in the State of Qatar. In addition, we aimed to examine variations in driving ... -
Relationship between Chauffeurs' Demographics, and Knowledge of Traffic Signs in the Kingdom of Saudi Arabia
( Elsevier B.V. , 2018 , Conference)Authorities in the Kingdom of Saudi Arabia (KSA) are investing heavily on developing Intelligent Transport Systems, which includes installations of Variable Message Signs (VMS) for the road users. However, it is challenging ... -
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 ... -
Speed perception and actual speed in a driving simulator and real-world: A validation study
( Elsevier Ltd , 2019 , Article)Background: Driving simulators have become an effective research tool in traffic safety, but the validity of results obtained in simulated environments remains a debated issue of high importance. Objective: The objective ... -
The relation between driving errors and executive functioning in intellectually able young novice drivers with autism
( Elsevier Ltd , 2019 , Article)Driving is a complex, goal-directed task. ASD can be related to impairments in executive functioning (EF), which may interfere with driving. This study aimed to investigate (1) if 16 young novice drivers with ASD exhibited ... -
A comparative study on the operational performance of four-leg intersections by control type
( Elsevier Ltd , 2018 , Article)The selection of proper control types at intersections at the planning stage is an important concern considering the difficulty in comparing the performance of different control types. Therefore, several manuals proposed ... -
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 ... -
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 ... -
Performance evaluation of the inside intersection median-turn lane markings on the mobility and safety performance of signalized intersections in the Philippines and Japan
( Elsevier B.V. , 2018 , Article)Signalized intersections are one of the key elements that play a vital role at road networks. The efficiency and safety levels of intersections can affect the operational performance of the whole system. In general, turning ... -
An experimental investigation into mechanical behavior of hybrid and nonhybrid composite semi-elliptical springs
( Elsevier, Ltd , 2013 , Article)This study introduces a new composite semi-elliptical suspension spring by utilizing fiber reinforced composite strength in principal direction instead of shear direction. Three types of composites were tested, namely, ...
