An overview of pedestrian signal setting and implementation in the State of Qatar
( Elsevier B.V. , 2017 , Conference Paper)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 ... -
Analysis of gap parameters for the estimation of single lane roundabouts' capacity in the State of Qatar
( Elsevier B.V. , 2021 , Conference Paper)Entry capacity is an important parameter for evaluating the roundabout performance. In general, entry capacity is influenced by three gap parameters: critical gap, follow-up time and minimum headway of circulating vehicles. ... -
Analysis of the Trajectories of Left-turning Vehicles at Signalized Intersections
( Elsevier B.V. , 2020 , Conference Paper)Internationally, an annual number of more than a million fatalities are caused by road traffic crashes, with particularly signalized intersections being crash prone locations within the highway system. An accumulation of ... -
Analyzing the impact of human characteristics on the comprehensibility of road traffic signs
( 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 ... -
Are Professional Drivers more Aggressive than General Drivers? A Case Study from Doha, Qatar
( Elsevier B.V. , 2022 , Conference Paper)Previous studies have revealed that aggressive and reckless driving can largely affect the occurrence and severity of road crashes. There could be intentional aggressive and unsafe acts, which could significantly affect ... -
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 ... -
Changes in Driving Behavior Across Age Cohorts in an Arab Culture: The Case of State of Qatar
( Elsevier B.V. , 2018 , Conference Paper)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 ... -
Consideration of a Pedestrian Speed Change Model in the Pedestrian-Vehicle Safety Assessment of Signalized Crosswalks
( Elsevier B.V. , 2017 , Conference Paper)Pedestrian safety is one of the most challenging issues in the road network. Understanding the pedestrian maneuver is the key to applying countermeasures against traffic crashes. It is known that behaviors of pedestrians ... -
Crowd Dynamics, Management and Control at Tourist Attractions during Special Events: A Case Study at Souq Waqif Using Pedestride® Crowd Simulation Tool
( Qatar Univesrity Press , 2020 , Conference Paper)"Large crowds can be expected at famous tourist attractions, e.g., Souq Waqif, during special events such as the FIFA World Cup 2022. A comprehensive understanding of crowd dynamics is extremely important in order to ... -
Development of a risk assessment tool based on driver behavior and environment
( Intelligent Transport Systems (ITS) , 2014 , Conference Paper)Driver error is the leading cause of vehicle crashes; roadway segment characteristics and environmental conditions follow. However, no safety prediction model has been introduced to estimate risk associated with driver ... -
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 ... -
Effectiveness of Speed Limit Pavement Markings at Transition Zones Along Expressways
( IEEE , 2020 , Conference Paper)Transition zones are usually equipped with speed limit signs only. Drivers usually miss the speed limit information provided through the roadside signs and travel faster than the posted speed limit. This driving simulator ... -
Emerging Transit Technology: Implementing an Urban Gondola System over Al Corniche, Doha, Qatar - A Cost Estimation Study
( Qatar Univesrity Press , 2020 , Conference Paper)Urban gondolas are a type of driverless transit vehicles, which are increasingly drawing the attention as a viable mass transit alternative in urban environments and touristic areas. The system is distinctive with high ... -
Energy absorption capabilities of complex thin walled structures
