САЖЕТАК / ABSTRACT:
Bringing urban transportation infrastructure underground brings many benefits, such as creating space for urban development, the reduction of noise and pollution and, thus, a significant increase in the quality of life, but also improving traffic safety and reducing deterioration of roads and rail by harsh environmental conditions. The high investment costs of building new tunnels or covering existing highways and rail lines with lids pay off on the long term, considering e.g., increasing real estate prices in the adjacent neighborhoods, increased productivity and reduced healthcare costs. The main aspects to be considered during the planning process are (1) total investment and operational costs, (2) impact of construction works, (3) safety, and (4) socio-environmental issues. The paper presents some basic planning principles, and experiences from a few projects in Europe and in the US are shared.
