On-board bus comfort is a key factor affecting the quality of transit service. Thus, its assessment is crucial for public transport companies, as it can support the monitoring, evaluation and implementation of specific actions to improve their services. Previous research mainly focused on separate subjective and objective measurements of on-board comfort. Furthermore, even if concurrent measurements of objective and subjective on-board comfort have been collected, no study has built a gradual scale for the real-time measurement of comfort. This paper covers this gap by integrating subjective measurements of driving style with objective measurements of longitudinal and transversal accelerations collected by intelligent transportation system tools. These findings are very useful because they represent the first contribution for establishing a comfort scale in a real operational environment as a tool to regulate driver behavior, i.e., each driver will be able to recognize when passengers experience conditions of discomfort and acts to improve comfort.

Children’s independent activities within public spaces emerge as a fundamental condition for their development considered in the context of their needs: socialization, movement, autonomy, and enrichment of their creative, imaginative, and cognitive potential. The promotion of their independence represents a relevant issue for implementing the smart city paradigm. This paradigm calls for a methodological framework where the urban fabric’s performance is evaluated via comprehensive analytic protocols. The proposed study presents an audit tool for evaluating the quality of urban spaces in terms of their practicability by children: the Survey on Conditions of Practicable Environments (SCOPE). The practicability of this research is establishing the quality of urban spaces’ usability, and it is expressed in terms of compositional, configurational, functional, and social factors of the built environment organized within a framework articulated in seven key dimensions (connectivity, convenience, comfort, commitment, conviviality, conspicuousness, and coexistence). The introduction of the concept of practicability and of indicators incorporating the demand for a children-sensitive perspective in the project of public spaces determine the novelty of the SCOPE procedure. This methodology was applied to an area in Central Cagliari, Italy, to evaluate the usability of public spaces. The results reveal that the proposed methodology is relevant for implementing the smart city paradigm because it addresses children’s autonomy and their rights to the city by selecting and defining indicators to clarify and assess conditions of the built environment conducive to children’s autonomy and independent social activities.

In this paper, the use of Fast Falling Weight Deflectometer (Fast-FWD) is analyzed as a non-destructive and quick test procedure to evaluate the efficiency of short-span bridges. The Fast-FWD is an instrument that can produce a broadband dynamic force up to an impact value of 120 KN: The impact is constant and replicable, providing accurate action measures of bridge stiffness in a truly short period (30 ms). In this paper, a single-span reinforced concrete bridge is investigated, using the Fast-FWD. The considered bridge, approximately 12.0 m long and 15.5 m wide, was in critical condition. The bridge is in a suburban principal road near to the City of Cagliari in Sardinia (Italy), with an Annual Average Daily Traffic of 13,500 vehicles/day, and was suddenly closed, creating serious problems for urban mobility. In these conditions, the investigation through other standard techniques is time-consuming and labor intensive. For this reason, it is important to introduce methods that can be rapid, accurate and cost-efficient. In this paper, bridge stiffness values obtained during the in situ experimental campaign were compared with finite element models values. The Fast-FWD has the potential to provide engineering information that can help us to better understand bridge condition, in a rapid and cost-effective procedure.
