“…Objective measures have been predominantly used in walkability research by developing walkability audits [25][26] and indexes [27,28,29] that evaluate and score the conditions provided to pedestrians. Such objective measures have been supported in Geographic Information Systems [30][31], multi-criteria analysis [25,32], virtual technologies [29,33], Web-based services, such as WalkScore, among others. Subjective measures have been supported on qualitative assessments based on stated preferences and individual perceptions usually collected through questionnaires or by consulting expert panels [34].…”

“…The characteristics of traffic (speed, volume), the characteristics of roads (lanes and directions) and the facilities for protecting pedestrians from traffic are factors with impact on walking. Public security is also a criterion with some impact on walking, mainly in cities characterised by urban violence [32]. Pedestrian facilities are infrastructure provided to enhance the pedestrian environment, to improve pedestrian mobility, safety, access, and comfort.…”

Smart and sustainable mobility have recently emerged as a solution to the problems incurred by the intensive use of motorised transport modes. For many decades, cities have been planned based on the needs of vehicle traffic, neglecting basic human needs for active mobility and the adverse effects of motorised traffic on the natural environment. However, walking is an environmentally friendly transport mode and a healthy form of making physical activity. Thus, walking becomes an essential component of the transport and urban policies for achieving a more sustainable development process. This paper presents the research project Smart Pedestrian Network (SPN) that aims at promoting walkability as one of the critical dimensions of smart and sustainable mobility in cities. The paper analyses the various components linked to SPN that can make a pedestrian network "smart" and, therefore, a feasible alternative to motorised transport modes. Three integrated components are analysed: i) an urban planning component supported in a GIS-based multi-criteria model to assess the conditions provided to pedestrians and to support the adoption of planning policies; ii) a smartphone app for pedestrian navigation, displaying optional routes according to the pedestrian preferences and needs; and iii) a business component to estimate and disseminate the multiple benefits of walking as well as the market potential of SPN. By promoting an innovative linkage of these three components, SPN has a great potential for improving walkability and, therefore, for creating more sustainable and liveable urban spaces.

“…Although the path condition (pavement, width, etc.) are also included as safety indicators in the above assessment tools, a fuzzy evaluation on walkability by adolescents proved that it is less important than public safety and traffic safety when it comes to CIM [41] . In addition, attack, harassment, bullying, and antisocial behaviors of strangers also pose social safety threats to CIM [42]~ [44] .…”

“…进行评价，其中"安全性"权重达到0.4，为三者中最高 [29] 。因此从步行友好性评价研究中提取"安全"相关指标是有效且有意义的。 CIM被定义为无父母监管时儿童在邻里环境内的自由活动 [30] ，安全是其最重要的影响因素，通常包含社会安全与交通安全两类 [31]~ [33] ，有研究还特别强调步行安全 [34] 。从CIM研究文献中也解析出了若干与步行友好性研究相一致的细化安全指标，例如交通量、交通速度等 [35]~ [39] ，但大多属于"机动车交通环境"指标大类，仅有"交通节点穿行保障"等 [37][39] [40] 属于"步行/骑行环境"指标大类。虽然现有评价工具中也包括步行道路状况(如铺装、宽度等)类指标，但青少年群体对社区步行友好性的模糊评价证实，相较于路面质量，公共安全与交通安全对独立出行的影响更大 [41] 。除此之外，来自陌生人的攻击、骚扰、欺凌及反社会行为等也是影响儿童独立出行的社会安全因素 [42]~ [44] ；"照明"则是一种值得探讨的增加夜晚出行安全感知的因素 [39] [40] ，可被纳入表4"步行/骑行环境"下的"其他设施"指标小类。值得注意的是， CIM研究对表4中"其他指标"类所涉及的环境因子也较为关注，尤其从儿童独立出行需求的角度探讨了更为广泛的安全问题，例如动物产生的威胁、迷路，以及熟人或关系良好的邻里-他们的视线可形成被动监督，也可以成为儿童寻求帮助的对象，从而为独立出行的儿童带来安全感 [43] [44] ，而这些因素在其他研究中往往被忽略，故而对CIM研究文献的检索有效地扩展了本研究的思路，有助于进一步完善评价指标框架。儿童通学研究也将安全因素作为重点研究内容，涵盖了诸多社会及物理环境因素，如邻里关系、陌生人的威胁、步行设施(包括交通信号灯、步行过街路口、步道数量等)、机动车交通量、街道机动车停放数量，以及道路连续度等。此外，"区域(社区)对道路安全的重视程度"是一项意识层面的新指标。 [45] [46] 此外，虽然驾驶员及行人的不可预测或不当行为 [47] [48] 也会对儿童出行造成安全威胁，但主要需通过公共安全教育 [49] 和严格执法 [50] 等非环境设计手段对其进行干预，故本研究不予以考量。 5 Conclusions…”

With the advent of cloud computing and wireless sensor networks, the number of cyberattacks has rapidly increased. Therefore, the proportionate security of networks has become a challenge for organizations. Information security advisors of organizations face difficult and complex decisions in the evaluation and selection of information security controls that permit the defense of their resources and assets. Information security controls must be selected based on an appropriate level of security. However, their selection needs intensive investigation regarding vulnerabilities, risks, and threats prevailing in the organization as well as consideration of the implementation, mitigation, and budgetary constraints of the organization. The goal of this paper was to improve the information security control analysis method by proposing a formalized approach, i.e., fuzzy Analytical Hierarchy Process (AHP). This approach was used to prioritize and select the most relevant set of information security controls to satisfy the information security requirements of an organization. We argue that the prioritization of the information security controls using fuzzy AHP leads to an efficient and cost-effective assessment and evaluation of information security controls for an organization in order to select the most appropriate ones. The proposed formalized approach and prioritization processes are based on International Organization for Standardization and the International Electrotechnical Commission (ISO/IEC) 27001:2013. But in practice, organizations may apply this approach to any information security baseline manual. Under many contradictory obstacles, the decisions made by humans are not reliable, because the human brain is only capable of evaluating and acting on a limited amount of information at any given moment [17]. To help decision makers solve actual problems for organizations, Thomas Sati (1980) [23] introduced the Analytical Hierarchy Process (AHP). This approach is based on the comparison of pairs between an alternative and a best possible alternative. The strength of the AHP lies in its neutral and logical classification and its flexibility to integrate various functions such as the deployment of quality functions, linear programming, and fuzzy. The benefit of the AHP methodology in conjunction with fuzzy logic is called fuzzy AHP which is the most important method of the multi-criteria decision-making methodology for various types of applications [24]. The fuzzy AHP approach helps to make decisions with various inclinations, fuzziness, and vulnerability. Research has shown the fuzzy AHP philosophy and furthered the supreme utilization of it [25]. It is practical for dealing with uncertainty, complexity, and decision making for complex issues of a controversial nature [26].The structure of the article is as follows: Section 2 is related to the integration of wireless sensor networks with cloud computing. Section 3 reviews previous approaches for the selection of ISCs in organizations. Section 4 presents the AHP, and...
