This two-part series of articles discusses the prospects of the next decade in which a slow rate of economic growth is likely to lead to a stabilisation, if not an actual decline in the availability of investment resources. Methods of investment appraisal are reviewed to show that the justification of many recent rapid-transit projects is doubtful. Often the need to get better use from existing facilities does not receive enough attention. The cost effectiveness of refurbishment is examined and the importance of good timing is investigated. Low-investment solutions will now have to be considered on equal terms withthe often simple but more expensive solution. A relief roadis generally more acceptable than a traffic restraint scheme. The authors use the request for increased vehicle weights by road hauliers to show that current working practices also play a part in the argument. Future project planning will require more accurate engineering costing thanwas the case in the past, and higher standards for costing expenditure will be needed. Much greater involvement in the costing of operations in disaggregated terms will be needed. (TRRL)
