STAGING INTER URBAN HIGHWAY CONSTRUCTION BY DYNAMIC PROGRAMMING
This paper presents a method of scheduling highway network construction which can maximize the long-term advantages of such an undertaking. The approach taken is spatial-analytic, and thus somewhat unrealistic from economic or planning points of view. Rather, a simple accessibility function is used to explore the implications of alternate staging policies. The model could easily be adapted to more realistic or satisfying goals, however. The model presented does not require a typical dynamic programming tableau of the benefits of advancing from one network state to each other, but calculates these values only as they are required. An heuristic modification of the struct dynamic model allows the treatment of problems of realistic size. The model is applied to scheduling a highway network for a set of Ontario and Quebec cities. The dynamic strategy appears to be only marginally more beneficial than a myopic one, suggesting that it might be better to persure a policy of building highway networks to meet present meeds.
