This paper aims to provide a framework for policy-makers and transportation and urban design professionals to evaluate alternative urban plans and infrastructure design, allowing them to select a set of locally relevant indicators to help assess scenarios considering sustainable development and overall system performance improvement in line with specific project goals. Using methods of systematic review, content analysis, multi-criteria analysis, and expert consultation, a three-level goal system is proposed, leading to the generation of 64 Key Performance Indicators (KPIs), both qualitative and quantitative, and an indicator set of 227 items. To allow stakeholders to apply their own set of indicators, the approaches and tools of measuring these indicators as well as the ways of using this indicator set are presented to assist decision-makers in evaluating and choosing optimal plans and designs.

In this paper, a set of indicators is presented that aim to identify promising service innovations for Accessibility as a Service (AaaS) and Mobility as a Service (MaaS); services that potentially can reduce the demand for transport and optimize use of transport infrastructure and vehicles in urban regions. The proposed indicators characterize service innovations from three different perspectives: 1) Is the service innovation environmentally sustainable? Does it reduce negative impacts on the environment (reduce carbon emissions, use of space), 2) Is it rewardable? Is value created for an organization? Does it make use of new sustainable business models, and 3) How widely is the service spread? How many users are there, what is the geographic distribution and what level of societal transition has occurred? The developed indicators are meant to guide policy makers, decision makers, business developers and academia in the prioritizations that need to be made when allocating land and resources to the most promising and powerful innovations, moving towards more environmentally friendly mobility and accessibility. The next step will be to test the indicators to identify and categorize existing and emerging new services, ideas, pilots and prototypes. The results of this second step will be presented in our next article.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

In recent years, tourism gentrification has made great progress in rural areas and has had significant impacts on these areas’ development, specifically in the domains of the economy, living standards, community, culture, and environment. Tourists play a key role in developing tourism gentrification in rural areas, but research investigating tourism gentrification in rural areas from the tourist perspective is scarce. To fill this gap, we focus on tourism gentrification and develop a measurement scale from the tourist perspective through multiple qualitative and quantitative steps. Our findings confirm that tourism gentrification in rural areas from the tourist perspective comprises eight dimensions: economic growth, enhanced environment, enhanced living standards, individual civilization, improved communication, promoted social environment, cultural appreciation, and improved individual quality. Through development and validation of the scale, we hope to offer a comprehensive referencing index of tourism gentrification in rural areas to policy makers and rural tourism practitioners.

China has proposed medical couplet body to alleviate residents’ difficulties in seeking medical treatment, and the future development ability of medical couplet body has gradually become a research interest. On the basis of prospect theory, this study constructs a comprehensive evaluation index system with qualitative and quantitative indexes, clear hierarchy, and diverse attribute characteristics. The development ability of medical couplet body is also comprehensively and systematically evaluated. In addition, the evidential reasoning method is proposed on the basis of the equivalent transformation of prospect value. Furthermore, the validity and feasibility of the model are proven through experiments, and the influence of decision makers’ risk attitude on the evaluation results is discussed.

Abstract Background Despite the increased emphasis placed on the use of evidence for policy development, relatively few initiatives have been developed to support evidence-informed decision-making, especially in West Africa. Moreover, studies examining the conditions under which policy-makers use research-based evidence are still scarce, but they show that their attitudes and opinions about research are one of the main determinants of such use. In February 2017, Burkina Faso’s Minister of Health planned to create a unit to promote evidence-informed decision-making within the ministry. Before the unit was set up, documenting the attitudes towards research at the highest levels of his Ministry appeared profitable to the unit’s planning. Method Individual interviews were conducted by the author with 14 actors positioned to consider evidence during decision-making from the Burkina Faso’s Minister of health cabinet. An interview grid was used to explore several themes such as attitudes towards research, obstacles and facilitators to research use, example of research use in decision-making and finally, ways to increase decision-makers’ participation in knowledge transfer activities. Interviews were partially transcribed and analysed by the author. Results The results show a mixed attitude towards research and relatively little indication of research use reported by respondents. Important obstacles were identified: evidence inaccessibility, lack of implementation guidelines, absence of clear communication strategy and studies’ lack of relevance for decision-making. Many suggestions were proposed such as raising awareness, improving access and research communication and prioritizing interactions with researchers. Respondents agree with the low participation of decision-makers in knowledge transfer activities: more leadership from the senior officials was suggested and greater awareness of the importance of their presence. Conclusions The conclusion presents avenues for reflection and action to increase the potential impact of the knowledge transfer unit planned within the Ministry of Health of Burkina Faso. This innovative initiative will be impactful if the obstacles identified in this study and policy-makers’ preferences and needs are taken into account during its development and implementation.

In recent decades, research has paid attention to the atmospheric ways computer-generated imagery (CGI) marks the experience of future urban design. What has been addressed in the generic abbreviation CGI has, however, exclusively concerned visualisations that communicate with stakeholders beyond designers and architects. Based on fieldwork within an urban design lab, the paper differentiates among the range of CGI used by urban designers. Focusing on collage, which forms one kind of CGI that has received scant attention in scholarly literature, I demonstrate its key function as an epistemological in-house work-in-progress tool that helps designers to refine their vision and to identify the atmosphere of future urban spaces. Based on New Aesthetics, collaging atmosphere is characterised by a physiognomic approach to urban space that selectively addresses aesthetic characteristics. Hence, the paper tackles a discussion that points towards cautious handling of the communicative scope of collages that can be well complemented by other types of CGI before entering a constructive dialogue with clients.

Redesigning and retrofitting cities so they become complex systems that create ecological and cultural–societal health through the provision of ecosystem services is of critical importance. Although a handful of methodologies and frameworks for considering how to design urban environments so that they provide ecosystem services have been proposed, their use is not widespread. A key barrier to their development has been identified as a lack of ecological knowledge about relationships between ecosystem services, which is then translated into the field of spatial design. In response, this paper examines recently published data concerning synergetic and conflicting relationships between ecosystem services from the field of ecology and then synthesises, translates, and illustrates this information for an architectural and urban design context. The intention of the diagrams created in this research is to enable designers and policy makers to make better decisions about how to effectively increase the provision of various ecosystem services in urban areas without causing unanticipated degradation in others. The results indicate that although targets of ecosystem services can be both spatially and metrically quantifiable while working across different scales, their effectiveness can be increased if relationships between them are considered during design phases of project development.

Several scholars have focused on the different approaches in designing convivial urban spaces, but literary evidence shows that the essence of aesthetic design in public urban spaces, by referring to the main dimensions involved in the shaping of urban vitality, has not been adequately researched. In this regard, this study, by hypothesizing that the quality of urban design leads to a vital urban environment, focuses on urban vitality from the aesthetic point of view. Thus, in using qualitative grounded theory as a main methodological tool and using a systematic review of the related literature as the main induction approach for collecting qualitative data, five main dimensions of urban vitality, which are necessary to attain a correlation with the aesthetic quality of urban design, were conceptualized. The study concludes that the aesthetic design of an urban setting has a direct effect on the active involvement of its users and that this, therefore, has a direct consequence on the level of public urban vitality, manifested. Integrating the complexity theory with the five main dimensions used for assessing urban vitality was suggested as a viable area for further research.

PurposeThe bid/no-bid decision is critical to the success of construction contractors. The factors affecting the bid/no-bid decision are either qualitative or quantitative. Previous studies on modeling the bidding decision have not extensively focused on distinguishing qualitative and quantitative factors. Thus, the purpose of this paper is to improve the bidding decision in construction projects by developing tools that consider both qualitative and quantitative factors affecting the bidding decision.Design/methodology/approachThis study proposes a mixed qualitative-quantitative approach to deal with both qualitative and quantitative factors. The mixed qualitative-quantitative approach is developed by combining a rule-based expert system and fuzzy-based expert system. The rule-based expert system is used to evaluate the project based on qualitative factors and the fuzzy expert system is used to evaluate the project based on the quantitative factors in order to reach the comprehensive bid/no-bid decision.FindingsThree real bidding projects are used to investigate the applicability and functionality of the proposed mixed approach and are tested with experts of a construction company in Alberta, Canada. The results demonstrate that the mixed approach provides a more reliable, accurate and practical tool that can assist decision-makers involved in the bid/no-bid decision.Originality/valueThis study contributes theoretically to the body of knowledge by (1) proposing a novel approach capable of modeling all types of factors (either qualitative or quantitative) affecting the bidding decision, and (2) providing means to acquire, store and reuse expert knowledge. Practical contribution of this paper is to provide decision-makers with a comprehensive model that mimics the decision-making process and stores experts' knowledge in the form of rules. Therefore, the model reduces the administrative burden on the decision-makers, saves time and effort and reduces bias and human errors during the bidding process.

Tripoli is a city of a Mediterranean Sea climate; this has contributed with some social and religious factors to affect the architectural and urban design, which all originally has come from the Islamic content. This study argues the climatic features of Tripoli in order to show the ways followed by the Libyan Muslim architect. In other words, these ways were used to adapt with the climate and create the demanding architectural treatments, which have served the building units. This is considered as a study case that can discuss the possibility of the climatic reflection on the walls. That is to say, the walls’ thickness, the type of the used substance in building, the substance’s properties, the type of roof used in covering the building units and the architectural design of the building as treatments achieved professionally by the architect in decreasing the heat in summer and increasing the heat in winter through the mass block. Additionally, the researchers have stated that Tripoli’s building design respected the privacy of the inhabitants and their isolation from the world outside their buildings. That is because they wanted to have their own cold spaces inside which were rich of light, air and shadow. As a result of the aforementioned considerations, the architectural buildings contained the uncovered space and the broken entrance to keep the privacy from the passengers and to protect the inhabitants from wind and sand. These were regarded as final solutions for the architectural and climatic problem. Further, this study illustrates the active role of using the planning including the architectural formations and the treatments of motion path. That is according to their width, their length, their form, their guidance and their direction change in order to make shadow and isolate the front of buildings. This also contributed to give the streets the northern wind which in turn helped to keep the air moving as long as possible to tone down the climatic influences. Moreover, the planning aimed to show its turn through analytical, architectural and documentary survey for realistic examples in the archeological registrar of the potential city treatments. These architectural elements were important in making the sustainable architecture in respect to the environment and human relaxation requirements. Finally, the researchers measured the following factors temperatures, wind, rain, and ratio humidity for variety of spaces in the city. That was followed by qualitative and quantitative statistical analysis supported by graphs
