The importance and public nature of road infrastructure requires involvement of many stakeholders in the process of decision making in the democratic societies. The usage of Multi–Criteria Analysis (MCA) is a pertinent tool in decision making when some of specific objectives are imperative to achieve. Besides, the road infrastructure is very important for the system of civil protection and defence for all countries. This work shows the methodology for definition of criteria and determination of weight for each criterion. The following six main criteria are assessed: traffic flow, impact of spatial plan, civil engineering criteria, economical and financial criteria, environmental criteria, criteria for defence and system of civil protection. More specific sub–criteria are defined in each group of main criteria. The questionnaire with a list of main and specific criteria is sent to several institutions and experts in the country to give their opinion thereon, or to estimate each main criterion (first step of weighting) as well as to assess each sub–criterion (second step of weighting). The results of the survey concerning measurement of the importance of each criterion are used to develop Multi–Criteria Analysis. The assessment of three variants of road infrastructure is calculated through three methods of MCA: Sum Weight Method (SWM), Analytic Hierarchy Process (AHP) and ELECTRE. The comparison and recommendation for usage of MCA and choice of the calculation method is also provided in this work.
