Modeling the Impact of Downstream Conditions on Discharging Behavior of Vehicles at Signalized Intersections Using Micro-Simulation
( Springer , 2020 , Article)© 2020, King Fahd University of Petroleum & Minerals. In areas where traffic demand is high and intersections are closely spaced, the drivers’ desire for quick discharge is demotivated by negative downstream conditions, ... -
Introducing a multi-variate classification method: Risky driving acceptance among different heterogeneous driver sub-cultures
( Elsevier , 2020 , Article)Introduction: Heterogeneous driving populations with many different origins are likely to have various sub-cultures that comprise of drivers with shared driver characteristics, most likely with dissimilar traffic safety ... -
Effect of ADHD traits in young drivers on self-reported deviant driving behaviours: An exploratory study in the Arab gulf region
( Elsevier , 2020 , Article)IntroductionAttention Deficit Hyperactivity Disorder (ADHD) can be defined in two key traits (inattention and hyperactivity-impulsivity), which can effect day-to-day capabilities such as driving performance. MethodsIn this ... -
Innovative countermeasures for red light running prevention at signalized intersections: A driving simulator study
( Elsevier , 2020 , Article)The change interval, which includes the yellow and all-red times, plays a crucial role in the safety and operation of signalized intersections. During this interval, drivers not only need to decide to stop or go but also ... -
Optical pavement treatments and their impact on speed and lateral position at transition zones: A driving simulator study
( Elsevier , 2021 , Article)© 2020 Elsevier Ltd Transition zones are a road section where posted speed drops from higher to lower limits. Due to the sudden changes in posted speed limits and road environment, drivers usually do not adapt to the posted ... -
Throughput optimization for the Robotic Cell Problem with Controllable Processing Times

Extraction of Vehicle Turning Trajectories at Signalized Intersections Using Convolutional Neural Networks
( SpringerLink , 2020 , Article)This paper aims at developing a convolutional neural network (CNN)-based tool that can automatically detect the left-turning vehicles (right-hand traffic rule) at signalized intersections and extract their trajectories ... -
A vision-based zebra crossing detection method for people with visual impairments
( IEEE , 2020 , Conference Paper)Safe navigation for visually impaired is challenging without assistive technology. This paper proposes a pedestrian crossing detection approach to help visually impaired people. We introduce the use of multiple convolutional ... -
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 ... -
