Drivers� crossing behaviour between express and local lanes with soft separation: A driving simulator study
(
Gioacchino Onorati Editore
, 2018 , Article)
In different countries, hard separation is adopted as a technique to separate express and local lanes. However, in case of an incident, especially on the express lane, traffic jams can occur as there is no escape route. ...
The Integration of Dynamic Lane Grouping Technique and Signal Timing Optimization for Improving the Mobility of Isolated Intersections
(
Springer Verlag
, 2017 , Article)
Spatial variations in traffic demand degrade intersection performance that can result in the waste of time�space resources. Existing control strategies of intersections assume fixed lane for movement assignment regardless ...
Usage of Non-Linear Regression for Modeling the Behavior of Motor Vehicle Crash Fatality (MVF) Rate
(
IEOM Society
, 2017 , Conference Paper)
Data analysis for vehicular crash counts is essential for transportation and traffic management systems (TTMS) to develop practical and innovative road safety interventions. The crash trend analysis, in particular, is the ...
The impact of perceptual countermeasures on driving behavior in rural-urban transition road segments: A driving simulator study
(
Gioacchino Onorati Editore
, 2018 , Article)
This driving simulator study investigated the impact of perceptual countermeasures on driving behavior by creating perceptual effects via pavement markings. Two different marking schemes (i.e. Optical Circles and Optical ...
Attitudes towards road safety among pre-drivers: The case of Qatar
(
IEOM Society
, 2018 , Conference Paper)
A preliminary study involving school students aged 12-18 years attempted to test whether there is difference in attitudes towards road safety between Arab and non-Arab respondents. The sampled participants were categorized ...
Magnetorheological damper with external excitation for more efficient control of vehicles? dynamics
(
SAGE Publications Ltd
, 2018 , Article)
This article presents a new concept design for magnetorheological dampers, where the excitation circuit and magnetic field are applied from outside the magnetorheological chamber. This magnetorheological damper was designed ...
Evaluating the effect of seasonal variations on walking behaviour in a hot weather country using logistic regression
(
Routledge
, 2018 , Article)
The city of Doha, Qatar experiences a hot and arid weather throughout the year. This study investigates the effect of season, type of day, and time of day on the walking behaviour of pedestrians in these conditions using ...
Motorcyclists’ Safety on Expressways: Subjective and Objective Evaluations
(
Springer Berlin Heidelberg
, 2019 , Article)
This study objectively and subjectively investigates the factors influencing motorcyclists’ safety on expressways. The relationships between motorcyclist stress while driving on expressways and potential influencing factors ...
Empirical Study on Pedestrian Signal Design and Compliance in the State of Qatar
(
Springer International Publishing
, 2019 , Article)
To ensure safe crossing manoeuvres at signalized crosswalks, the pedestrian delays and allocation of sufficient pedestrian green and flashing green times should be considered at design stage. The pedestrian signal settings ...
Modelling trends in road crash frequency in Qatar State
(
Inderscience Enterprises Ltd.
, 2019 , Article)
The data-based regression models are widely popular in modelling the relationship between the crash frequencies and contributing factors. However, one common problem usually associated with the classical regression models ...
