SUMMARY Since 1965 an underground‐railway is built in Hannover. For this project a cost‐benefit‐analysis was established. The present article discusses those problems, which will emerge whenever such an analysis for public transport investments will be carried out. To begin with it is shown that under certain conditions concerning the distribution it is possible to justify pure efficiency analyses. The result of the calculation points out that the present value of the difference between all the recorded benefits and costs amounts to DM 287,400,000.‐. The applied rate of discount is 6.5 per cent. The assumed economic life of the project is 50 years. The internal rate of return is 10.1 per cent. After the discussion of some problems of estimating the real costs of construction and operation, it is described how it was possible, to estimate the quantity of private transport, which will divert to the underground‐railway after its opening. Furthermore a technique is given, which allows the conversion of the benefits according to the diverted and the generated traffic into time savings. Time‐savings contribute 82 per cent to the total recorded benefits. An attempt was made, to justify the evaluation of those savings with average wage rates.
