The French Ministry of Transport published on 20th October 1998 a new guideline to assess the road investment projects on interurban areas on the economic point of view. This guideline is a planning transportation method implemented to optimise the choice of investment. As with the previous guideline, this one proposes to perform the economic assessment on two different topics: (1) An appraisal of effects in monetary terms; and (2) An appraisal of effects that cannot be valued in monetary terms. To perform the effects in monetary terms, a cost benefit analysis is implemented. But the originality of this guideline is the economic consequences on other modes of transport are estimated especially when a motorway is expected to compete against a railway line. Furthermore, some of the environmental effects are monetarised, particularly the impacts of road projects on noise, air pollution and greenhouse effects. However, the above approach does not permit to know the spatial distribution of the economic effects. So, an appraisal of the consequences of the projects on the regions is carried out. This non-monetarised approach attempts to estimate the impact of the project on employment during construction and operation. Moreover the effects of the project on the changes of accessibility are calculated of each area newly served. The indicator used permits to estimate the change of market size generated by a new road on companies. An approach is also proposed to assess the consequences of the new road on the intensification of competition between companies due to accessibility gains, which bring market closer. This paper presents what is really new in this guideline re assessment of road projects. For the covering abstract see ITRD E105584.
