Abstract
The major causes of investment riskiness into transport infrastructure relate to international economy instability, lack of clearly defined and accurate information on the overall processes of international intermodal transportation, absence of objective information due to inconsequent market research as regards interpretation of economic, political and other aspects.
Assessment of objective integrated investments into public transport sector as a very specific branch of economy should necessarily be evaluated as multiple indicators affecting different spheres of community, and the final solution should be drawn when all multi-criteria indicators are well appraised. Economy based grounding of the optimal choice from all possible variants when solving specific tasks of the transport sector, depends on the economic expediency of the constructed subject. The main factors of effective usage of investments become apparent in the process of solving the task of road or railway network development optimisation.
