Modeling and simulation of pedestrian movement planning around corners
(
MDPI AG
, 2019 , Article)
Owing to the complexity of behavioral dynamics and mechanisms associated with turning maneuvers, capturing pedestrian movements around corners in a mathematical model is a challenging task. In this study, minimum jerk and ...
Traffic safety culture of professional drivers in the State of Qatar
(
Elsevier B.V.
, 2019 , Article)
Professional drivers play a significant role within the traffic system of the State of Qatar. With developing infrastructure, the need for professional drivers is growing. However, knowledge is lacking about their perception ...
Analysis of road traffic crashes in the State of Qatar
(
Taylor and Francis Ltd.
, 2019 , Article)
Road traffic crashes (RTCs) are globally acknowledged as increasing threat to society, because they can affect many lives when they result in severe injury or fatality. In the State of Qatar RTCs are getting more awareness ...
Pedestrians' Speed Analysis at Signalized Crosswalks
(
Elsevier B.V.
, 2018 , Conference Paper)
Pedestrian speed is essential for designing signal timings as well as for understanding pedestrian safety issues. This paper presents analysis of three types of pedestrian speeds (entry speed, crossing speed, and exit ...
Investigating the Impacts of Graphical Route Information Panel Layouts on Drivers’ Comprehension and Response Time
(
Springer Verlag
, 2019 , Article)
Graphical route information panels (GRIPs) are an alternative to conventional text-based variable message signs to address different traveler information needs. Since drivers are traveling at higher speeds on the motorways, ...
Variable message sign strategies for congestion warning on motorways - A driving simulator study
(
Gioacchino Onorati Editore
, 2018 , Article)
Congestion and stopped traffic on motorways constitute a potential safety hazard for drivers. In particular, unexpected hard congestion tails are the causes of serious rear-end crashes as they compromise the drivers' ability ...
Changes in Driving Behavior Across Age Cohorts in an Arab Culture: The Case of State of Qatar
(
Elsevier B.V.
, 2018 , Conference Paper)
In this investigation, we aimed to examine the structure of the Driving Behavior Questionnaire (DBQ) across age cohorts spanning 14 to 55 years in the State of Qatar. In addition, we aimed to examine variations in driving ...
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 ...
An overview of pedestrian signal setting and implementation in the State of Qatar
(
Elsevier B.V.
, 2017 , Conference Paper)
Pedestrian signal control is a main influencing factor on the Level of Service of crossing facilities and on the safety performance considering conflicts with vehicles. In signal design, pedestrian clearance time is a key ...
Consideration of a Pedestrian Speed Change Model in the Pedestrian-Vehicle Safety Assessment of Signalized Crosswalks
(
Elsevier B.V.
, 2017 , Conference Paper)
Pedestrian safety is one of the most challenging issues in the road network. Understanding the pedestrian maneuver is the key to applying countermeasures against traffic crashes. It is known that behaviors of pedestrians ...
