Currently, the two major types of transportation tunnels being constructed are highway and rail transit. The technological and institutional improvements which are needed in order to reduce capital construction costs can be achieved by an effective Federal research and development program which is responsive to the industry needs. A responsive R&D program should be based on clearly defined cost benefit ratios; hence demand forecasting is an integral part of the R&D activity. Demand studies can also provide guidance to policy makers in all sectors of the tunneling industry, such as the needed capacity of the industry to meet projected construction. How much the increase in tunneling might be through the 1980's is the subject of the paper.
