Social And Environmental Impacts

Purpose – The purpose of this paper is to identify and categorize the social and environmental impacts of transportation systems, and address the appropriate solutions to mitigate and manage these impacts in order to achieve sustainability. Design/methodology/approach – This research performs a comprehensive literature review to suggest a framework on socio-environmental impacts of transportation and related solutions. The proposed framework is analyzed through quantitative methods and a survey study in freight transport. Findings – Findings support the direct relation of potential solutions and socio-environmental impacts of transportation. All four categories of solutions (technological, socio-economic and political, cultural and behavioral, and infrastructure related) reveal direct impact on reduction of environmental impacts. However only technological solutions were found to be influential on social impacts of the transportation. Originality/value – To the best of the authors’ knowledge there has not been any comprehensive framework covering social and environmental impacts of transportation in the literature. In addition, this paper categorizes potential solutions to enhance socio-environmental performance of the transportation and investigates their effectiveness.

Oriented Approach

Recent advances in the fields of data communication and automated controls make the implementation of automated highway systems (AHSs) more possible. Currently, substantial research effort is being made on the design of intelligent transportation system (ITS) architectures in Europe, Japan, the United States, and Canada. These architectures, however, have major limitations inherit in the design methodology used. Most ITS developers use a process-oriented approach for the design of the architecture that reduces its quality attributes (stability and flexibility) to future changes. This paper presents an approach to implement object-oriented design methodology in the Canadian intelligent transportation system (C-ITS) architecture for AHS. It was also shown that the C-ITS architecture needs a backup communication system to be integrated within the C-ITS architecture. Such a backup system would aid the reliability of future transportation systems to be developed based on this architecture. The proposed C-ITS architecture promotes flexibility, stability, and communication and, as such, should be of interest to ITS developers and researchers.Key words: intelligent transportation systems, architecture, automated highways, object-oriented approach, backup communication.

The Given

Purpose – The purpose of this paper is to explore use of the Theory of Constraints (TOC) approach in addressing traffic congestion as the main impediment to improving utility of the land transportation systems. The observed element is a motorway segment with regulated access. Design/methodology/approach – As the literature addressing this topic is rare or nonexistent, this study employs exploratory design, developing tentative theory through the generation of new ideas and assumptions forming grounded picture as a base for further investigation. Findings – The study concludes that the most binding constraint is broken in the third out of the TOC’ five steps and that the improvement in the given segment of the land transportation system is possible to be achieved using this framework. Originality/value – Although the merits of use of TOC have been considered in other than just production-planning environments, its application in land transportation systems has never been examined. This study presents one of the rare, if not the only attempt to make use of this unique theory that is systematised in the systems management paradigm within the realm of land transportation systems.

Purpose This study aims to investigate the relationship between the concreteness of searching module icons and their effectiveness in Iranian digital library applications. Design/methodology/approach This study was a correlational survey whose participants consisted of two groups, namely, users and experts. The former consisted of 174 users, all of whom were included because of their scarcity, and the latter included ten experts of knowledge and information science. First, the effective and non-effective icons were identified by users. Then, their concreteness was investigated by the expert participants. Findings The results of the study showed a significant relationship between the concreteness of icons and their effectiveness, meaning that the more concrete, the more effective the icon was, and vice versa. Furthermore, it was shown that the effective icons were representational and semi-abstract, whereas non-effective ones were very abstract. Practical implications The designers, especially digital library practitioners, should use icons that distinguish themselves as effective icons, and avoid using non-effective ones. It is suggested that they apply representational icons more. Social implications The designers of mobile interfaces and public environments, such as social networks, transportation systems and so forth, can use icons in their user interfaces that are more effective when they are perceived with more concreteness. Originality/value The investigation of the relation between the concreteness of icons and their effectiveness may help determine effective and non-effective icons. It can also be of help to designers to satisfy user needs and improve their site’s performance through using effective icons.
