A Real Case-Based Study Exploring Influence of Human Age and Gender on Drivers’ Behavior and Traffic Safety
( Springer Verlag , 2018 , Conference Paper)The demand for understanding the functional relationship between changes in traffic safety level and human-related factors has increased remarkably due to a steady increase in population and traffic volume. Motor vehicle ... -
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 ... -
Analyzing the impact of human characteristics on the comprehensibility of road traffic signs
( IEOM Society , 2018 , Conference Paper)Traffic safety is one of major challenges facing most communities worldwide. To improve traffic safety, regulating traffic movement through markings, signs, channelization, and others is essential. Traffic signs are used ... -
An assessment tool to evaluate complete streets in developing countries: The case of Qatar
( Inderscience Enterprises Ltd. , 2018 , Article)Complete streets refer to a simple and effective transportation policy to improve traffic safety and comfort for all users within urban areas. Car dependency is a major concern in developing countries. Endorsing complete ... -
Ridge penalization-based generalized linear model (GzLM) for predicting risky-driving index
( IEOM Society , 2018 , Conference Paper)Road traffic crashes remain one of the major causes of preventable death and injury worldwide. Human behavior is considered one of the main factors leading to such tragic losses. In this paper, we analyze the responses of ... -
The performance assessment for the dMEWMA in capturing changes in simple linear profiles
( IEOM Society , 2018 , Conference Paper)In traditional quality control, the quality of product is typically modeled as the univariate or multivariate distribution of the quality parameters. In more recent applications, the quality is modeled using the relationship ... -
Analysis of illegal pedestrian crossing behavior on a major divided arterial road
( Elsevier Ltd , 2018 , Article)Pedestrians’ illegal mid-block crossing increases the chances of a crash compared to crossing at marked or signalized crosswalks. Therefore, it is necessary to have an accurate understanding of this type of behavior to be ... -
Well-to-wheel water footprints of conventional versus electric vehicles in the United States: A state-based comparative analysis
( Elsevier Ltd , 2018 , Article)Today, increasing levels of water demand become a particularly serious challenge for many countries, especially since water is an essential element for production of transportation fuels. Unfortunately, no research efforts ... -
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 ... -
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 ... -
Pedestrians' Crossing Behavior at Marked Crosswalks on Channelized Right-Turn Lanes at Intersections
( Elsevier B.V. , 2017 , Conference Paper)Unsignalized marked crosswalks are problematic locations from pedestrians' safety perspective. Although the priority rule at such locations is clear; pedestrians have the absolute right of way over vehicles, driver often ... -
Studying critical pedestrian behavioral changes for the safety assessment at signalized crosswalks
( Elsevier B.V. , 2017 , Article)Pedestrian-vehicle conflicts are one of the most important safety concerns at signalized intersections especially in urban areas. Conflicting vehicles and pedestrians select their maneuvers by predicting the other user ... -
The effectiveness of applying dynamic lane assignment at all approaches of signalized intersection
( Elsevier Ltd , 2017 , Article)Existing traffic control strategies at signalized intersections aim at the optimization of signal timing parameters while assuming fixed lane assignments to the movements at each approach. Such control results in the waste ... -
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 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 ... -
Modeling pedestrian crossing speed profiles considering speed change behavior for the safety assessment of signalized intersections
( Elsevier Ltd , 2017 , Article)Pedestrian safety is one of the most challenging issues in road networks. Understanding how pedestrians maneuver across an intersection is the key to applying countermeasures against traffic crashes. It is known that the ... -
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 ... -
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 ...
