ABSTRACT

Unlike for road rehabilitation or maintenance, no network level management models have been developed for new investments to transportation facilities to improve access, to increase capacity or to achieve other socially desirable goals. Yet, highway investment takes 40-80 percent of the road budget, and its share on other modes is not negligible. Two or three road network design models aimed at this objective have, however, been proposed. In this paper 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; it considers investment trade-offs between regions, between functional classes of roads, and between most important modes of transport; and, importantly, between other road expenditures. The model also has an ability to incorporate multiple criteria and multiple objectives; and it focuses comprehensively on policy rather than on (at that level) unimportant technical details of demand and supply models. These are important attributes when compared to other available transport investment models which are either macroscopic or multimodal but not both.
