Road scene analysis for determination of road traffic density

引用

Frontiers of Computer Science 2014年第4期8卷 619-628页

作者： omar AL-KADI Osama AL-KADI Rizik AL-SAYYED Ja'far ALQATAWNA King Abdullah lI School for Information Technology University of Jordan Amman 11942 Jordan College of Engineering and Computer Science Australian National University Canberra ACT 0200 Australia

Road traffic density has always been a concern in large cities around the world, and many approaches were developed to assist in solving congestions related to slow traffic flow. This work proposes a congestion rate estimation approach that relies on real-time video scenes of road traffic, and was implemented and evaluated on eight different hotspots covering 33 different urban roads. The approach relies on road scene morphology for estimation of vehicles average speed along with measuring the overall video scenes randomness acting as a frame texture analysis indicator. Experimental results shows the feasibility of the proposed approach in reliably estimating traffic density and in providing an early warning to drivers on road conditions, thereby mitigating the negative effect of slow traffic flow on their daily lives.

Evidence-based Nomenclature and Taxonomy of Research Impact Indicators

引用

Journal of Data and Information Science 2020年第3期5卷 33-56页

作者： Mudassar Arsalan omar Mubin Abdullah Al Mahmud School of Computer Data and Mathematical SciencesWestern Sydney UniversityAustralia Centre for Design Innovation Swinburne University of TechnologyAustralia

Purpose: This study aims to classify research impact indicators based on their characteristics and scope. A concept of evidence-based nomenclature of research impact(RI) indicator has been introduced for generalization and transformation of scope. Design/methodology/approch: Literature was collected related to the research impact assessment. It was categorized in conceptual and applied case studies. One hundred and nineteen indicators were selected to prepare classification and nomenclature. The nomenclature was developed based on the principle—"every indicator is a contextual-function to explain the impact". Every indicator was disintegrated into three parts, i.e. Function, Domain, and Target ***: The main functions of research impact indicators express improvement(63%), recognition(23%), and creation/development(14%). The focus of research impact indicators in literature is more towards the academic domain(59%) whereas the environment/sustainability domain is least considered(4%). As a result, research impact related to the research aspects is felt the most(29%). Other target areas include system and services, methods and procedures, networking, planning, policy development, economic aspects and commercialisation, etc. Research limitations: This research applied to 119 research impact indicators. However, the inclusion of additional indicators may change the result. Practical implications: The plausible effect of nomenclature is a better organization of indicators with appropriate tags of functions, domains, and target areas. This approach also provides a framework of indicator generalization and transformation. Therefore, similar indicators can be applied in other fields and target areas with modifications. Originality/value: The development of nomenclature for research impact indicators is a novel approach in scientometrics. It is developed on the same line as presented in other scientific disciplines, where fundamental objects need to classify on com
