| Abstract: | We combine the concept of reserve capacity with the discrete network design problem. On the one hand, we try to find the maximum possible increase in traffic demand by setting traffic signals at individual intersections. On the other hand, we construct new road in order to increase the whole capacity of a road network. A programming model and the heuristic solution algorithm are proposed to solve the reserve capacity problem of optimal signal control. The applications of the model and its algorithm are illustrated with one numerical example. |
