No network level management models have been developed for new investments in transportation facilities to improve access, increase capacity, or achieve socially desirable goals. Yet investment takes 40 to 80% of the road budget, and its share of other modes is not negligible. Two or three road network design models aimed at this objective have been proposed. A model is described having the dual objective of network design and comprehensive, multimodal transport investment. The proposed model suits the management structure and style of most transport agencies because it is based on hierarchical decision making and considers investment tradeoffs between regions, functional classes of roads, most important modes of transport, and other road expenditures. The model incorporates multiple criteria and multiple objectives, and it focuses comprehensively on policy rather than unimportant technical details of demand and supply models. These important attributes are lacking in other available transport investment models, which are either macroscopic or multimodal but not both.
