“…Methods and means of providing tourism business growth in different regions, tourist's safety, ecological problems, etc, are also widely discussed [5][6][7]. At the present moment, a lot of railways are being closed because of less volume of passenger transportation and, consequently, unprofitability [8].…”

The authors used a complex of mathematical models meant for the optimal investment of the processes of creation and use of the railway transport infrastructure. The specific features of these models are as follows: long-term period of realization of the infrastructure projects, many participants with special interests, which do not always coincide, a lot of factors of uncertainty connected with the choice of quantities of the calculation parameters, etc. The authors created economic-mathematical models of the discrete optimal planning of the railway tourism operations. This takes into account conditions of risks and cooperation, and allows to determine sets of effective routes which are most profitable ones, provided they meet the established demands. The latter includes routes which meet maximum criteria of the net costs under the conditions of the established system of demands for the activity of the tourism operators.

“…Once closed and connected regions of grains have been obtained, their boundaries have been processed via a specifi cally adapted Watershedtype algorithm [13,14] in order to check and, if needed, repair the irregularities in the grain boundary shape as well as to subdivide the connected regions with a slight difference in colorimetric texture. In the fi nal part, the procedure extracts the quantities of interest to determine the aggregate particle size distribution [5] under examination.…”

“…A specifi c research has therefore been carried out to develop a procedure for determining railway ballast particle size distribution by means of the image processing technique. Such a technique has already given very good results when adopted in railway monitoring [1,2,3,4,5] as well as in numerous other fi elds of transport engineering [6,7,8,9,10,11]. The equipment used in the analyses consists of a high-resolution 16.1MP camera placed on a tripod at a prefi xed height of 0.80 m. The experimentation has been conducted on a new Italian railway line, along the section "EMS/La Malfa -Cardillo" in Palermo which already had laboratory data acquired by a certifi ed authority and in complete conformity with the Italian Railway Network Specifi cations (Capitolato RFI, n. XXXX OD D IF SP XX.XX.X.X 001 B).…”

The mechanical characteristics of the railway superstructure are related to the properties of the ballast, and especially to the particle size distribution of its grains. Under the constant stress-strain of carriages, the ballast can deteriorate over time, and consequently it should properly be monitored for safety reasons. The equipment which currently monitors the railway superstructure (like the Italian diagnostic train Archimede) do not make any “quantitative” evaluation of the ballast. The aim of this paper is therefore to propose a new methodology for extracting railway ballast particle size distribution by means of the image processing technique. The procedure has been tested on a regularly operating Italian railway line and the results have been compared with those obtained from laboratory experiments, thus assessing how effective is the methodology which could potentially be implemented also in diagnostic trains in the near future.

“…The gradual increase in private mobility, dating back to the second half of the last century in western countries, has caused the shutdown of several secondary railway lines which are rarely used and therefore little profitable to any institution, either owner or manager (Guerrieri and Ticali, 2012).…”

“…walking and cycling routes). The following reasons support the success of this type of requalification measure: i) separation of railway sediment from the ordinary road network; ii) reduced number of intersections with the road network; iii) moderate longitudinal slopes; iv) long straight roads and large horizontal radii; v) width compatibility between the railway platform and that for cyclists and pedestrians; vi) interconnection between urban centers and routes passing often through areas of great natural value, hardly accessible by alternative modes of transport; and vii) links with other public transport services (Guerrieri and Ticali, 2012).…”

Finding a new use for neglected infrastructures, such as disused railways, provides an opportunity for low carbon travel experiences as reconversion policies promote new uses, arrest decay processes and re-establish continuity in the environmental system, using existing linear infrastructures.Nevertheless, the decision of what to do in order to reuse abandoned railways represents a complex decision making problem, involving heterogeneous impacts and stakeholders. Within this context, Multi Criteria Analysis techniques can be used to synthesize stakeholders' preferences by accommodating conflicting and incommensurable impacts. The present study thus uses MultiCriteria Analysis to answer a real demand for transportation systems' planning coming from the Piedmont Region Authority in Italy, where 12 passenger railway lines have recently been abandoned and replaced by bus services.The main objective of the study is to develop a methodological framework able to support collaborative planning and decision-making processes related to the requalification of disused railways in mixed urban and rural contexts.The ultimate objective is to provide a robust recommendation to the Regional Authority with reference to the best requalification option for the abandoned railway line under analysis. The contribution brought by the study is twofold and refers to: (i) improved operability of the proposed tools obtained by combining visualization analytics with consolidated preference elicitation protocols for assessing multiple impacts and (ii) the provision of a replicable working tool for policy makers. The study has thus an innovative value and may increase the use of Decision Analytics to support the evaluation of environmental impacts of different transportation systems.
