“…Disaster risk is the interaction between the vulnerability of an area and the existing threat hazards [28]. The level of vulnerability in an area can be reduced, thus enhancing the capacity to face these threats [29]. The magnitude of disaster risk can be expressed in the amount of loss (property, lives, injuries) for a specific event magnitude [30].…”

Bantul is one of the regencies in the Special Region of Yogyakarta (DIY) that are prone to earthquakes. In 2006, Yogyakarta was hit by a tectonic earthquake with a magnitude of 5.9 on the Richter scale, resulting in a death toll of 6,234 people, with 1,754 severely injured (e.g., spinal injuries) and in need of paraplegia rehabilitation. The high number of casualties indicates a high disaster risk, which means high disaster vulnerability and low disaster management capacity. The research aims to assess disaster risks based on the community’s vulnerability and capacity in facing the 2006 earthquake disaster in DIY. This study uses a mixed method, consisting of a survey with 44 disaster victims suffering from injuries that result in disabilities (paraplegia) and in-depth interviews with ten family members of the victims. The results show that disaster vulnerability will likely result in a physical risk, i.e., disaster injuries that leave the victims with paraplegia. Such vulnerability is caused by the community’s low capacity and poor response to disasters, including the 2006 earthquake. Another physical risk is the collapsing houses, which lead to economic risk as the community suffers losses of between 30 and 91 million rupiah. Meanwhile, the social risk is a change in the status of the victims from people without disabilities to people with disabilities. That said, social relations increase because the disaster victims with paraplegia have become active members of an organization.

“…Reconstruction of transportation infrastructure aims to identify factors that contribute to disaster mitigation in order to predict construction costs (Safapour & Kermanshachi 2021). All transportation infrastructure needs are not necessarily recoverable in terms of costs because they have uncertain capacity (Itoh 2018).…”

Effective mitigation planning is needed for communities living in areas prone to disasters, including natural calamities such as volcanic eruptions. The development of disaster evacuation routes in disaster-prone areas, including the area where this study was conducted, requires proper planning in transportation infrastructure. Ternate city in Indonesia is a disaster-prone area because of the presence of an active volcanic mountain and an area traversed by the Pacific ring of fire. This area includes a vulnerable zone that has the potential for disasters such as volcanic eruptions, therefore it is important to make mitigation plans to assist the community in evacuating and reducing the impacts of a disaster. Data was obtained from road network observations and by carrying out inventory surveys on the condition of facilities and infrastructure for land transportation and sea transportation in Ternate city, which is located close to Mount Gamalama. A quantitative approach was utilised in this study through transportation modelling using Vissim to analyse the existing traffic conditions and forecasting. The research aims to formulate disaster mitigation measures to reduce the damages caused by the volcanic eruption of Mount Gamalama and identify plans for evacuation routes in disaster-prone areas. The road network performance of Ternate city showed that the city has roads that can be used as evacuation routes for disaster victims. It has good road performance in terms of meeting points and final evacuation points. Efforts to reduce the number of victims when a volcanic eruption occurs, the socialisation of disaster mitigation to the community and the installation of disaster information signs need to be equipped with the preparation of evacuation routes in the form of evacuation gathering points and final evacuation points. This study recommends local governments to develop new evacuation routes in disaster-prone areas and increase evacuation capacity.

“…This evaluation method can be useful to choose the alternative that minimizes costs, once having defined the intervention to be carried out. For example, in Malnaca et al [28], the total cost of ownership model is utilized to estimate the economic viability of a technological solution to convert a diesel bus into an electric bus, in Itho [29], an analysis on the cost and CO2 emissions impact in function of substituting functional characteristics of the drivetrain of the vehicle, was carried out.…”

A Sustainable Evaluation Processes for Investments in the Transport Sector: A Combined Multi-Criteria and Cost–Benefit Analysis for a New Highway in Italy

In the transport sector, a rational and shared planning process is commonly based on the comparison of different design alternatives through quantitative evaluations and stakeholders’ engagement. Among the most adopted evaluation methods, there are cost–benefit analysis (CBA) and multi-criteria analysis (MCA). Both these methods have strengths and weaknesses, which do not allow the conclusion that one technique is dominant over the other. Starting from these considerations, the aim of this paper is to propose a sustainable evaluation process for investments in the transport sector, based on the combined use of both CBA and MCA analysis and a stakeholders’ engagement. The proposed evaluation method was also applied to a real case study: the decision-making process for a new highway in a high naturalistic and touristic area in north of Italy. Furthermore, a “weighted criteria process definition” based on the Delphi method was also performed within a public engagement process. Research results show that the application of both the evaluation analyses (CBA and MCA) allows the selection of the most rational althernative from a sustainable, shared and technical point of view. Precisely, the estimations performed underline that the CBA analysis significantly underestimated the non-users’ benefits, while the opposite occurred for the MCA analysis. The incidence of the non-users’ benefits is only the 14% of the total for the CBA, while it reaches more than the 79% for the MCA. This result is very relevant underling how, for a decision-making processes aimed in comparing different design alternatives for which non-users impacts are expected as relevant against the users ones, the unique application of the most consolidated CBA analyses are not always adequate, while the joint use of the two evaluation methods ensures robust and rational choices for a sustainable development.
