Transport models incorporate network optimization techniques to improve efficiency by addressing the challenges of traffic congestion and transport delay. These models aim to maximize transport capacity while minimizing the average number of hops . One approach is the use of multi-objective optimization algorithms, such as the network centrality guided multi-objective particle swarm optimization (NC-MOPSO), which explores optimal edge weight assignments and routing paths to achieve a trade-off between transport capacity and efficiency . Another approach is the simulation-based optimization (SBO) model, which integrates activity-based travel demand simulation with a multi-objective network optimization algorithm. This model accounts for the stochastic behavior of commuters and real-time decisions made in response to changing network dynamics . Additionally, a non-dominated sorted genetic algorithm (NSGA-II) is used to solve the multi-objective optimization problem of bus networks, considering transfer efficiency and operation costs . These network optimization techniques aim to design efficient and economic networks that balance the benefits of passengers and operators .
