Modelling speed behaviour in rural highways: Safety analysis of driving under adverse road-weather conditions
(
PLOS
, 2021 , Article)
This study proposes a methodical approach to model desired speed distributions under different road-weather and traffic conditions followed by identification of road-weather conditions with potentially higher safety risks ...
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. ...
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 ...
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 ...
Autonomous vehicles between anticipation and apprehension: Investigations through safety and security perceptions
(
Elsevier Ltd
, 2021 , Article)
Due to the ongoing enormous infrastructural developments and car ownership culture in Qatar, it could be one of those countries to introduce Autonomous Vehicles (AV) technology at the early stages. Therefore, this study ...
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 ...
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 ...
A novel agent-based framework for evaluating pedestrian safety at unsignalized mid-block crosswalks
(
Elsevier Ltd
, 2021 , Article)
A critical safety problem in road networks is the conflicts on unsignalized crosswalks. Thus, a proactive approach to assess pedestrian safety performance is required. Simulating the microscopic road user behavior in a ...
