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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Studying critical pedestrian behavioral changes for the safety assessment at signalized crosswalks
( Elsevier B.V. , 2017 , Article)Pedestrian-vehicle conflicts are one of the most important safety concerns at signalized intersections especially in urban areas. Conflicting vehicles and pedestrians select their maneuvers by predicting the other user ... -
The effectiveness of applying dynamic lane assignment at all approaches of signalized intersection
( Elsevier Ltd , 2017 , Article)Existing traffic control strategies at signalized intersections aim at the optimization of signal timing parameters while assuming fixed lane assignments to the movements at each approach. Such control results in the waste ... -
Pedestrians' Crossing Behavior at Marked Crosswalks on Channelized Right-Turn Lanes at Intersections
( Elsevier B.V. , 2017 , Conference)Unsignalized marked crosswalks are problematic locations from pedestrians' safety perspective. Although the priority rule at such locations is clear; pedestrians have the absolute right of way over vehicles, driver often ... -
An overview of pedestrian signal setting and implementation in the State of Qatar
( Elsevier B.V. , 2017 , Conference)Pedestrian signal control is a main influencing factor on the Level of Service of crossing facilities and on the safety performance considering conflicts with vehicles. In signal design, pedestrian clearance time is a key ... -
Usage of Non-Linear Regression for Modeling the Behavior of Motor Vehicle Crash Fatality (MVF) Rate
( IEOM Society , 2017 , Conference)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 ... -
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 ... -
Modeling pedestrian crossing speed profiles considering speed change behavior for the safety assessment of signalized intersections
( Elsevier Ltd , 2017 , Article)Pedestrian safety is one of the most challenging issues in road networks. Understanding how pedestrians maneuver across an intersection is the key to applying countermeasures against traffic crashes. It is known that the ... -
The Integration of Dynamic Lane Grouping Technique and Signal Timing Optimization for Improving the Mobility of Isolated Intersections
( Springer Verlag , 2017 , Article)Spatial variations in traffic demand degrade intersection performance that can result in the waste of time�space resources. Existing control strategies of intersections assume fixed lane for movement assignment regardless ...
