This paper proposes a systems approach for estimating investment requirements for a highway network with uncertain demands. The problem is formulated as a mathematical program with equilibrium constraints, assuming that travel demands belong to an ellipsoidal likelihood region and that traffic flows on the underlying network are in user equilibrium. The proposed algorithm obtains a solution by solving a sequence of problems. Numerical results from the nine-node and Sioux Falls networks demonstrate that the proposed approach is able to produce a solution that guarantees the future system performance without requiring an excessive amount of investment.
