Do detection-based warning strategies improve vehicle yielding behavior at uncontrolled midblock crosswalks?
( Elsevier Ltd , 2021 , Article)Pedestrians being the most vulnerable road users account for a large proportion of injuries and fatalities from road traffic crashes. Pedestrians are involved in around one-third of the whole fatalities coming from the ... -
Driving simulation sickness and the sense of presence: Correlation and contributing factors
( Elsevier Ltd , 2021 , Article)Driving simulators are useful and effective tools for conducting studies in the field of traffic safety. Simulation sickness (SS) and the sense of presence (SP) are two well-known factors that could affect the results of ... -
Experimental analysis of additively manufactured thin-walled heat-treated circular tubes with slits using AlSi10Mg alloy by quasi-static axial crushing test
( Elsevier Ltd , 2019 , Article)In this study, additively manufactured aluminum thin-walled tubes with different slit dimensions are proposed to improve energy absorption efficiency. A total of 18 samples, which varied in the number of slits, slit length, ... -
Exploratory study on self-awareness and self-preparedness of Malaysian rail passengers for emergency evacuations
( Elsevier Ltd , 2022 , Article)This study explores the self-awareness and self-preparedness among Malaysian rail passengers during potential emergency evacuations. A questionnaire survey was carried out at a major rail transit terminal in Kuala Lumpur, ... -
Fuel consumption at signalized intersections: Investigating the impact of different signal indication settings
( Elsevier Ltd , 2023 , Article)The fuel consumption of vehicles depends on various factors including vehicle design, driving style, traffic management, and road design. Many manufacturers have been developing efficient and smart vehicles, which contributes ... -
GIS-based spatiotemporal analysis for road traffic crashes; in support of sustainable transportation Planning
( Elsevier Ltd , 2023 , Article)Road traffic crashes pose a significant challenge worldwide, necessitating increased efforts to reduce them and promote sustainable transport systems. This study aimed to investigate spatiotemporal road traffic crashes and ... -
Improved traffic safety at work zones through animation-based variable message signs
( Elsevier Ltd , 2021 , Article)Work zones are established to provide a safe environment for all road users and road workers. However, based on the statistics, they can be considered as crash prone zones due to changes in the road alignments and the ... -
Interactions between autonomous vehicles and pedestrians at unsignalized mid-block crosswalks considering occlusions by opposing vehicles
( Elsevier Ltd , 2021 , Article)Visibility can be identified as one of the critical determinants for the safety performance of autonomous vehicles (AVs) on unsignalized mid-block crosswalks (UMC), which may be significantly influenced by build-up environment ... -
Investigating the impact of a novel active gap metering signalization strategy on driver behavior at highway merging sections
( Elsevier Ltd , 2021 , Article)A safe headway to the lead vehicle is important to reduce conflicts with merging vehicles from highway on-ramps. Previous research has outlined the advantage of gap metering strategies to yield sufficient space to merging ... -
Investigating the impact of dynamic merge control strategies on driving behavior on rural and urban expressways – A driving simulator study
( Elsevier Ltd , 2019 , Article)Harsh decelerations and abrupt lane changes of drivers on the outer expressway lane in response to merging platoon vehicles from on-ramps increase the crash- and congestion risk on expressways. Several merge control ... -
Measuring sustainability, resilience and livability performance of European smart cities: A novel fuzzy expert-based multi-criteria decision support model
