A Simulated Annealing for Optimizing Assignment of E-Scooters to Freelance Chargers
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2023 , Article)
First- and last-mile trips are becoming increasingly expensive and detrimental to the environment, especially within dense cities. Thus, new micro-mobility transportation modes such as e-scooter sharing systems have been ...
Application of PERS to Evaluate Walkability in State of Qatar
(
Qatar University Press
, 2023 , Conference Paper)
Well-designed pedestrian facilities are essential to promote walking among residents. These facilities also act as safe space for use of cycling and other personal mobility vehicles. In 2018, Ministry of Transport developed ...
Integrated modelling for sustainability assessment and decision making of alternative fuel buses
(
Elsevier
, 2023 , Article)
In this paper, a hybrid life cycle sustainability assessment (LCSA) model integrating multi region input–output analysis with novel multi-criteria decision-making techniques is proposed to assess three different fuel ...
Assessment of different pedestrian communication strategies for improving driver behavior at marked crosswalks on free channelized right turns
(
Elsevier
, 2023 , Article)
Introduction: Previous studies have indicated low driver yielding rates to pedestrians in various countries. This study analyzed four different strategies to improve driver yielding rates at marked crosswalks on channelized ...
Transforming Challenges into Opportunities for Qatar’s Food Industry: Self-Sufficiency, Sustainability, and Global Food Trade Diversification
(
MDPI
, 2023 , Article)
Food trade restrictions pose a serious risk for countries that are heavily reliant on food imports, potentially leading to food crises, inequality, and geopolitical conflicts on a global scale. However, such restrictions ...
Exploring Crowd Management and Evacuation Strategies using Microscopic Pedestrian Simulation: A Case Study of Souq Waqif
(
Qatar University Press
, 2023 , Conference Paper)
Safe egress plans are critical for crowd evacuation at touristic attractions, particularly during special events, as visitors are often unaware of their options. Identification of bottlenecks in the walking spaces are vital ...

(
Taylor & Francis
, 2023 , Article)
Objective: Taxis have become an integrated component of Qatar’s urban transportation network due to their convenience, comfort, and flexibility. Qatar has seen an uptick in the demand for professional taxi drivers. Most ...
GIS-based spatiotemporal analysis for road traffic crashes; in support of sustainable transportation Planning
(
Elsevier Ltd
, 2023 , Article)
Road traffic crashes pose a significant challenge worldwide, necessitating increased efforts to reduce them and promote sustainable transport systems. This study aimed to investigate spatiotemporal road traffic crashes and ...
Rebound effects undermine carbon footprint reduction potential of autonomous electric vehicles
(
Springer Nature
, 2023 , Article)
Autonomous vehicles offer greater passenger convenience and improved fuel efficiency. However, they are likely to increase road transport activity and life cycle greenhouse emissions, due to several rebound effects. In ...
Lane-based analysis of the saturation flow rate considering traffic composition
(
Informa UK Limited - Taylor & Francis
, 2023 , Article)
Saturation flow rate (SFR) is an essential metric for estimating the capacities of signalized intersections. Many factors, including traffic composition, configuration and geometry of the intersection, and driver behavior, ...
