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 ...
Development, validation, and application of School Audit Tool (SAT): An effective instrument for assessing traffic safety and operation around schools
(
MDPI AG
, 2019 , Article)
There is a need for a reliable school audit tool with well-defined scales to convert qualitative evaluation of existing school sites into a quantitative assessment in order to help public agencies to improve schools' safety ...
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 ...
Throughput optimization for the Robotic Cell Problem with Controllable Processing Times
(
EDP Sciences
, 2017 , Article)
In this paper, we present a MIP-based heuristic and an effective genetic algorithm for the Robotic Cell Problem with Controllable Processing Times (RCPCPT). This problem arises in modern automated manufacturing systems and ...
Modeling pedestrian gap acceptance behavior at a six-lane urban road
(
Taylor and Francis Inc.
, 2019 , Article)
The illegal crossing behavior of pedestrians at unmarked mid-block sections is unsafe, risky, and increase the potential of severe conflicts and crashes, especially in the case of multilane roads. This paper investigates ...
Road users' behavior at marked Crosswalks on channelized right-turn lanes at intersections in the state of Qatar
(
MDPI AG
, 2019 , Article)
At non-signalized marked crosswalks, pedestrian priority is neither well-defined nor well acknowledged by drivers. This paper presents the findings of an investigation on both driver and pedestrian behavior at non-signalized ...
A Strategy for Emergency Vehicle Preemption and Route Selection
(
Springer Verlag
, 2019 , Article)
Emergency vehicle preemption (EVP) aims to give right of way to emergency vehicles (EV) heading toward the incident location through a network of signalized intersections by creating a green wave en-route. The design goals ...
Performance Evaluation of Vehicle Restraint Systems in the Context of Design and Installation
(2021 , Article)
Vehicle Restraint Systems (VRS), a necessary component of the road design, are widely implemented by transport authorities to protect vehicles from severe incidents, mainly colliding to the roadside as well as median ...
