A New Bi-level Program Based on Unblocked Reliability for a Continuous Road Network Design
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 3
Abstract
With increasing demands for better and more reliable service, developing a method for designing a highly-reliability road network has become a critical issue. A Network Design Problem is used to determine a set of design parameters leading to the creation of an optimal road network. Moreover, the performance of an Origin-Destination pair with high traffic demands is a top priority in the optimizing process. A bi-level programming technique, that is upper-level and lower-level programs, can be used to formulate the Continuous Network Design Problem. This study establishes a new type of bi-level program based on unblocked reliability. The proposed bi-level program is applied to analyze a real local road network that has 22 nodes and 62 links. A set of link capacity expansions is determined by solving the proposed bi-level program using the Hooke-Jeeves algorithm. This kind of capacity expansion results in optimization by maximizing the balance between the unblocked reliability of the entire road network and the road network expansion ratio. The new, proposed bi-level program can comply with the various limits on environment and financial resources.
