  7. Abstract:
  8. Natural disasters claim major losses in human lives and belongings, as well as national infrastructures. Taking major earthquake as an example, the study has considered two sides of the problem, both before and after the incident. The former side is formulated as a multipartite optimization problem, in which each party’s activities are directed toward the long-term solution of the original problem. A heuristic method to solve the multipartite problem, and solve three example problems to show the applicability of the method was proposed. The solutions of example problems show that a directed problem solution reaches a better solution (in terms of the objective function value) than the individual sub-problem solutions. The results of the three example problems showed improvements between 7.6 to 27.1 percent in the objective function for different cases. The later side of the problem focuses on calibration of a Logit choice model which predicts the online contra flow directions of strategic lanes based on the set of directions obtained from offline scenarios. The calibrated Logit model is then tested for Forth Worth network. The results show good performance of this approach in generating beneficial strategies, including increase of up to 16 percent in throughput compared to no contra flow case
