    Notes: Abstract This paper explains the need for the application of cost-benefit analysis to the evaluation of alternative projects for investment in the transport field and outlines briefly the historical development of the technique. The results of a comparative survey of a number of cost-benefit studies which have been carried out in Britain and some conclusions as to their thoroughness and comprehensiveness (or otherwise) are presented. The article concludes with a number of specific and detailed recommendations to remedy apparent methodological weaknesses. Six of these recommendations seem to merit particular attention: (1) The viewpoint of most studies should be extended so as to avoid confinement, for example, within an arbitrary local government boundary, and a wider range of “externalities” should be considered. Intangibles should be included explicitly in all such evaluation exercises. (2) The actual incidence of costs and benefits should be examined in order to indicate the directional impact of the project and its implications in terms of equity. The elimination of transfer payments and double-counting should be postponed until the latest possible stage in the evaluation. (3) Equity considerations should be investigated in any transportation plan, since most projects have considerable equity implications for particular areas or socio-economic groups. (4) Discounted cash flow techniques, which are still used only in a minority of transportation studies, should become standard practice. Most evaluations are based on a single-year rate of return, or at best on simple trend forecasting. More resources should be devoted to proper evaluation of alternative plans which give due importance to the cost and benefit streams through time. (5) Sensitivity analysis should be used in all transportation evaluations. Knowledge of the impact of different assignments, shadow prices, and discount rates are essential information for any decisionmaker. (6) Last, but not least, much greater communication should exist between analyst and decisionmaker than has existed in the past.

    Notes: Abstract Officials at various levels around the world are getting increasingly worried about the growth in automobile ownership and all the associated environmental problems that this implies. Voices are often heard advocating the exclusion of automobiles from the central areas of cities, much easier to say than to realise, unless the area is entirely reconstructed under a comprehensive redevelopment scheme, as, for instance, in the city of Västeras, Sweden. Another possible solution is to introduce some type of traffic restraint scheme involving compulsory rearrangement of the vehicular flow through the central area. The report deals firstly with an experiment carried out during the highly intensive, pre-Christmas shopping days in December 1969, when parts of the central business area of the city of Gothenburg, Sweden (population around 450,000) were closed to all unauthorised vehicles. The experience gained with this scheme was valuable when the next stage was being planned, i.e., a permanent traffic restraint scheme which was put into effect on August 18, 1970. Most of the report deals with the objectives, planning, realisation, and experience of the traffic restraint scheme, which involved dividing the central business area into five separate zones. During the first six months, several surveys were conducted to establish the impact of the scheme on vehicular flow, parking, pedestrian flow, public transport, accidents, air pollution, noise, and retail businesses. The scheme put into operation in Gothenburg has been a great success, having accomplished most of its objectives, and will be expanded to cover a still larger area in subsequent years.

    Notes: Abstract This paper discusses the aesthetic and ecological effects of highways. Little is known about the subject at the present time, and thus this treatment cannot be considered in any sense definitive. Part I offers a definition of aesthetic quality and considers its relevance to highway planning. It is noted that, although the principles of rural freeway design (curvilinear alignments, variable medians, etc.) generally accord with the aesthetic character of rural areas, freeways are infinitely more difficult to integrate aesthetically into urban areas. Comparisons are made in this regard among basic types of freeways. Part II notes that the effect of man's presence on the earth's ecology has resulted in new systems and processes to which man is now subject. Highways, as works of man, affect him and his environment in ways which are known only imperfectly. Nevertheless, there are steps which can be taken to minimize the more obvious forms of damage to the environment which can result from highway building. Part III discusses procedures for incorporating aesthetic and ecological considerations into highway planning. No method yet proposed is in itself sufficient, and none leads to a decision on an objective basis. A generally acceptable method must await further research. In the meantime, every effort must be made to assure full and fair consideration of environmental effects on an ad hoc basis.

    Notes: Abstract Urban transportation is identified as a functional element in the broader context of urban facilities and services. From this point of view, the relative merits of separate information systems for transportation planning and general urban planning, as contrasted to unified systems for all urban management functions, are discussed. The overriding need to make the most effective use of urban resources argues strongly for the unification of urban information systems to the greatest possible extent consistent with the special data requirements of various functional programs. The need to identify and correlate data items for very small areal units and to keep current records of the constantly shifting patterns of social and economic activities in urban areas present difficult, but not insurmountable technical problems. However, the most serious barrier to the development and implementation of comprehensive urban information systems is concluded to be institutional, rather than technical, in nature.
