Abstract EN
The throughput of a given transportation network is always of interest to the traffic administrative department, so as to evaluate the benefit of the transportation construction or expansion project before its implementation.
The model of the transportation network capacity formulated as a mathematic programming with equilibrium constraint (MPEC) well defines this problem.
For practical applications, a modified sensitivity analysis based (SAB) method is developed to estimate the solution of this bilevel model.
The high-efficient origin-based (OB) algorithm is extended for the precise solution of the combined model which is integrated in the network capacity model.
The sensitivity analysis approach is also modified to simplify the inversion of the Jacobian matrix in large-scale problems.
The solution produced in every iteration of SAB is restrained to be feasible to guarantee the success of the heuristic search.
From the numerical experiments, the accuracy of the derivatives for the linear approximation could significantly affect the converging of the SAB method.
The results also show that the proposed method could obtain good suboptimal solutions from different starting points in the test examples.
