Rapid Transit Network Design: A New Model and Solution Algorithm

Rapid Transit Network Design Problem (RTND) is a mathematical model which aims to find the best rapid transit routes combination. In this study, a new mathematical model and a solution algorithm is presented for RTND. This proposed model is formulated as a Mixed Integer Programming (MIP), which maximizes transit network coverage as its objective function. The author also design, a solution algorithm is suggested, which is composed of five main procedures: 1) Route Generation, 2) Route Combination, 3) Network Coverage Evaluation (NCE), 4) Branch Cutting, and 5) NCE Skipping. Route generation procedure specifies a set of candidate routes. Next, a search tree building strategy is applied to perform the search process through the candidate set. Afterwards, for a given transit network, NCE procedure should be executed to determine transit network coverage. Finally, the last two procedures, branch cutting and NCE Skipping criteria, are designed to recognize route combinations that cannot be optimal, and keep them away from executing NCE procedure. The algorithm is implemented in C# and some benchmark problems are used to evaluate its efficiency. The comparison between a computational time and a benchmark study shows an outstanding improvement achieved by this algorithm.
