Can automated driving prevent crashes with distracted Pedestrians? An exploration of motion planning at unsignalized Mid-block crosswalks
(
Elsevier
, 2022 , Article)
Pedestrian distraction may provoke severe difficulties in automated vehicle (AV) control, which may significantly affect the safety performance of AVs, especially at unsignalized mid-block crosswalks (UMCs). However, there ...
A reliability-based weather-responsive variable speed limit system to improve the safety of rural highways
(
Elsevier
, 2022 , Article)
Weather-responsive Variable Speed Limit (WRVSL) systems treat speed limits as weather-dependent random variables, as opposed to the conventional static speed limits. This study (i) evaluates drivers’ response to a fixed ...
Road safety status during COVID-19 pandemic: exploring public and road safety expert’s opinions
(
Taylor & Francis
, 2022 , Article)
The main objective of this study is to investigate the status of traffic safety and the public perception of traffic safety during the during COVID-19 pandemic. Three different data sets are used in this study: road crash ...
A study on the determinants of Ethiopian minibus taxi drivers' speeding behaviour: An application of the 'major theorists' model
(
Elsevier B.V.
, 2022 , Article)
Speeding is the most common road safety problem that results in many traffic accidents in Addis Ababa, Ethiopia. Minibus taxis substantially contribute to speed-related road traffic crashes in Addis Ababa. This study aimed ...
Analysis of Stopping Sight Distance (SSD) Parameters: A Review Study
(
Elsevier B.V.
, 2022 , Article)
Stopping sight distance (SSD) is one of the important elements in geometric highway design, which relies on the two key parameters, i.e., vehicle braking characteristics and drivers' reaction time. Previous studies have ...
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. ...
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 ...
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 ...
