 The paper deals with the issue of evaluation of socioeconomic impacts of occurrences emerging from railway infrastructure. The presented research results form part of a broader research subject focusing on the evaluation of the socioeconomic benefits of projects for the implementation of measures aimed at increasing the safety and reliability of railway infrastructure. The research topic addresses a part of the evaluation of railway infrastructure project efficiency within its life cycle using the cost–benefit analysis method. The methodology is based on the description and definition of input variables that are essential for the process of evaluating socioeconomic impacts. It is followed by another important step, which is the analysis of the categories and the number of occurrences, separately, for regional and national lines, and, further, the data is sorted according to whether occurrences emerge at stations or on a wide line. The result of the presented research is an overview of the calculated values of the expected socioeconomic impacts of partial occurrences according to the categories related to the year of operation on the railway infrastructure and the unit of measure. The research team carried out an inquiry into the annual impacts of the subcategories of occurrences related to one railway station and one kilometer of wide line, e.g., for national lines, the impacts of €2922.72/station/year and €41.67/km of wide line/year were determined. The results of the presented research represent important and necessary inputs for the next phase of the research topic, i.e., the evaluation of the socioeconomic benefits of projects increasing the safety and reliability of railway infrastructure.

Investigations on the socioeconomic impacts of mega-dam projects have tended to focus on conventional cost–benefit analysis, while studies exploring perceptions of local communities, who are some of the prime beneficiaries of these development initiatives, are limited. This paper aims to address this research gap through a case study of community perceptions on the socioeconomic impacts of the Merowe Dam in Sudan from the residents of upstream, downstream, and relocated locations. Data were collected primarily through surveys and interviews with residents, government officials, dam implementation authority, non-governmental organizations (NGOs) and other key informants and a series of indicators were developed for the analysis from the responses. Three inter-related areas of impact were scrutinized: (a) electricity generation; (b) development of modern agriculture; and (c) institutional infrastructure in the region. The results reveal that local communities are fully aware of both the positive and adverse socioeconomic impacts of the Merowe Dam, although these are focused more on the visible impacts closely related to their livelihood and income, such as increased food production, water shortages, electricity supply and its costs. Policy implications include investments in the new settlement areas with respect to the agricultural economy, such as irrigation improvement through electrification, promoting crop diversity, research, development, and diffusion of modern agricultural technologies. Efforts are also needed to strike a balance between provision of utilities and services, (i.e., water, electricity and other infrastructural facilities) provided by the Merowe Dam, amongst communities in relocated, upstream, and downstream locations.

This paper combines the most popular tourism typologies or goals (i.e., RT, responsible tourism, to represent impact minimisation; ST, sustainable tourism, to represent welfare maximisation; AT, alternative tourism, to represent continuity maximisation) and decision-making methodologies (i.e., MCA, multi-criteria analysis; CBA, cost-benefit analysis; WLCA, weighted life-cycle assessment; MLCA, monetary life-cycle assessment) in a single dynamic framework to operationally match the former with the latter. Normative insights show that MCA and WLCA are most suitable for RT and AT, respectively, whereas CBA and MLCA are most suitable for ST. Management recommendations (i.e., if a wrong static instead of a right dynamic approach must be adopted due to a lack of data, once chosen a tourism typology or goal, ST is the best in terms of level, correlation and likelihood of errors) are provided, and policy recommendations (i.e., if a right dynamic approach is adopted, in choosing among tourism typologies or goals, AT is the best in terms of precaution, ST is the best in terms of correlation, and RT is the best in terms of risk of investments) are suggested for a case study characterized by negative environmental and cultural dynamics. Positive insights show that two and many papers have applied WLCA and MLCA, respectively, to RT, but they did not account for cultural features; many papers have applied CBA to ST, but only one paper applied MLCA; few and no papers have applied MCA and WLCA, respectively, to AT.

A public decision by several countries on whether to cofinance an international infrastructure project is the subject of a cost–benefit analysis (CBA). The CBA elements are broken out and analyzed for each country. The issue of freight user benefits is discussed, and results are derived from a partial equilibrium model and point toward practical applicability. A recent analysis of the Fehmarn Belt Bridge, which will connect Denmark and Germany in a link in the Trans-European Network for Transport, is used for illustrative purposes.

The life cycle length of pavement with asphalt concrete material (ACM) surfacing is significantly influenced, in addition to transport loading and climatic conditions, by design method and rehabilitation timing. Appropriate overlay thickness calculation and estimation of optimal rehabilitation time are crucial to maximizing life cycle length and, concurrently, reducing road administration costs and road user costs. This article describes a comprehensive method of ACM rehabilitation design. For optimization of life cycle cost analysis (LCCA) based design, mathematical analytical solution in combination with experimental verification of physical, mechanical, and fatigue characteristics is utilized. Pavement performance, that is, functions mathematically describing pavement’s degradation characteristics of operational capability, is represented by longitudinal and transverse unevenness; these are used to describe relations between traffic loading and pavement’s bearing capacity on 1 : 1 scale. Optimizing of rehabilitation plan is carried out by making a cost benefit analysis (CBA) for several rehabilitation scenarios in which different rehabilitation timing produces different capital cost requirements and social benefits. Rehabilitation scenarios differ in technology, the design of which needs to be mathematically optimized, and timing of rehabilitation execution. This article includes a case study for the sake of illustration of practical results and verification of applicability of used methodology.
