Effect of U-turns and heavy vehicles on the saturation flow rates of left-turn lanes at signalized intersections
( MDPI , 2020 , Article)© 2020 by the authors. The Saturation Flow Rate (SFR) is a primary measure that can be used when estimating intersection capacity. Further, the efficiency of signal control parameters also depends on the accuracy of assumed ... -
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 ... -
Effectiveness of Driver Simulator as a Driving Education Tool
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference)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)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)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 ... -
Empirical evaluation of change in crash risk due to lane marking reallocation: A case study in Kochi City, Japan
( Elsevier , 2023 , Article)Lane markings are considered an essential component of a road system. As highlighted in previous studies, they are directly linked to efficiency and safety. The rearrangement or reallocation of lane markings can be an ... -
Empirical evaluation of drivers’ start-up behavior at signalized intersection using driving simulator
( Elsevier , 2020 , Article)Start-up behavior at signalized intersection mainly depends on perception reaction time of drivers to the green phase. This study investigated the start-up behavior at signalized intersections by considering reaction time, ... -
Empirical Study on Pedestrian Signal Design and Compliance in the State of Qatar
( Springer International Publishing , 2019 , Article)To ensure safe crossing manoeuvres at signalized crosswalks, the pedestrian delays and allocation of sufficient pedestrian green and flashing green times should be considered at design stage. The pedestrian signal settings ... -
Energy absorption capabilities of complex thin walled structures
( Institute of Physics Publishing , 2017 , Conference)Thin walled structures have been used in the area of energy absorption during an event of a crash. A lot of work has been done on tubular structures. Due to limitation of manufacturing process, complex geometries were ... -
Enhancing Pedestrian Safety through the Development of Advanced Operational Strategies for Crosswalks in Residential Areas
( Qatar University Press , 2021 , Poster)Pedestrians are the most vulnerable group in the traffic. Every year approximately 40,000 pedestrians are killed in the world due to road traffic crashes. In the state of Qatar, the situations are even worse with around ... -
Enhancing the learning-to-drive process for autistic learners in Qatar
( Elsevier , 2024 , Article)Obtaining a driver's license can be a stressful task for autistic drivers because of autism related characteristics. Due to the absence of an autism-tailored driving training program in Qatar, instructors may lack the ... -
Evacuation under flooded conditions: Experimental investigation of the influence of water depth on walking behaviors
( Elsevier , 2021 , Article)Flooding can be considered as the most frequent type of natural disaster, and it is an unavoidable phenomenon in many parts of the world. Ensuring the safety of people during such natural disasters is extremely important. ... -
Evaluating the Operational Impact of Left-Turn Exclusive Number of Lanes: A Case Study from Qatar
( Qatar Univesrity Press , 2020 , Conference)Left-turning movements can significantly reduce the overall capacity of signalized intersections due to the queueing built up. Intersections with heavy left-turning volumes tend to use multiple lanes to accommodate left-turn ... -
Examining the role of road safety audits worldwide: exploring road safety expert’s opinions
( Taylor & Francis , 2022 , Article)Road safety audit (RSA) is a method used to proactively identify safety risks in road projects from planning, design, and construction stages. The effectiveness of the implementation of RSAs varies across the globe. This ... -
Experiences with licensing by autistic drivers: An exploratory study
( Elsevier B.V. , 2022 , Article)Autistic individuals obtain their driver's licenses significantly less or significantly later than non-autistic peers. In the past, research has been done on what problems autistic individuals experience when (learning to) ... -
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, ... -
Exploring Crowd Management and Evacuation Strategies using Microscopic Pedestrian Simulation: A Case Study of Souq Waqif
( Qatar University Press , 2023 , Conference)Safe egress plans are critical for crowd evacuation at touristic attractions, particularly during special events, as visitors are often unaware of their options. Identification of bottlenecks in the walking spaces are vital ... -
Exploring driver behaviors during tailgating situations: a driving simulator study
( Elsevier , 2023 , Conference)The characteristics of drivers vary from one individual to another and one culture to another, leading to distinct driving behaviors exhibited by different drivers. This study aims to explore drivers’ car-following behaviors ... -
