Innovative countermeasures for red light running prevention at signalized intersections: A driving simulator study
( Elsevier , 2019 , 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 ... -
Autism-friendly public bus transport: A personal experience–based perspective
( SAGE , 2022 , Article)Community participation and the formation of social networks are crucial for a qualitative life. To this end, transportation plays an essential role. Many autistic people rely on public transportation for their mobility ... -
Improved driver behaviour at bus stops on local roads: Comparison of different treatments
( Elsevier , 2022 , Article)Every day, millions of students use school bus as a mean of transportation to and from schools. Nevertheless, most of the school bus related crashes occur at or near bus stops. The overtaking of stopped school buses during ... -
Crowd Evacuation through Crossing Configurations: Effect of Crossing Angles and Walking Speeds on Speed Variation and Evacuation Time
( Multidisciplinary Digital Publishing Institute (MDPI) , 2022 , Article)The design of safe and efficient pedestrian facilities necessitates the knowledge of complex human movements, such as intersecting pedestrian streams, under different conditions. This study aims to experimentally investigate ... -
Application of Unsupervised Machine Learning Classification for the Analysis of Driver Behavior in Work Zones in the State of Qatar
( Elsevier , 2022 , Article)Work zone areas are commonly known as crash-prone areas. Thus, they usually receive high priority by road operators as drivers and workers have higher chances of being involved in road crashes. The paper aims to investigate ... -
Safer pedestrian crossing facilities on low-speed roads: Comparison of innovative treatments
( Elsevier , 2022 , Article)Despite the international efforts to improve pedestrian safety in different regions of the world, pedestrian fatalities still account for around one-third of annual road traffic deaths. Residential areas are commonly ... -
A Simulated Annealing for Optimizing Assignment of E-Scooters to Freelance Chargers
( Multidisciplinary Digital Publishing Institute (MDPI) , 2023 , Article)First- and last-mile trips are becoming increasingly expensive and detrimental to the environment, especially within dense cities. Thus, new micro-mobility transportation modes such as e-scooter sharing systems have been ... -
Queue Discharge at Freeway On-Ramps Using Coordinated Operation of a Ramp Meter and an Upstream Traffic Signal
( Elsevier , 2020 , Conference Paper)Ramp metering is an effective way of maintaining optimum traffic conditions and mitigating congestion on freeways. Several strategies for ramp metering exist in the literature. They are typically based on the freeway traffic ... -
Integrated Multi-Criteria Model for Long-Term Placement of Electric Vehicle Chargers
( Institute of Electrical and Electronics Engineers , 2022 , Article)Based on the global greenhouse gas (GHG) emissions targets, governments all over the world are speeding up the adoption of electric vehicles (EVs). However, one of the key challenges in designing the novel EV system is to ... -
Rethinking mobility strategies for mega-sporting events: A global multiregional input-output-based hybrid life cycle sustainability assessment of alternative fuel bus technologies
( Elsevier , 2022 , Article)Sustainability has been enshrined in the official claims of mega sporting events, and scholarly debates persist on how to achieve environmental stewardship and a prolonged legacy. Revitalizing the public transportation ... -
Study of mild steel sandwich structure energy absorption performance subjected to localized impulsive loading
( MDPI AG , 2020 , Article)Extensive research focus had been given to sacrificial sandwich panels to mitigate the effects of blast loads. This is due to their ability to distribute the load and absorb a significant portion of the blast energy. This ... -
