To address the problems of unclear functions, unclear positioning, and insufficient integration with rail transit after rail networks are formed in major cities, this study reconstructs an integrated public transportation network system dominated by rail transit from a multi-dimensional perspective of “3-dimensional system, 2-dimensional line network, and 1-dimensional line”. The study analyzes the implementation strategy of rail-bus “dual network” integration in detail, proposes a hierarchical and step-by-step optimization method and implementation path for the “express-trunk-branch” bus network, and applies theoretical methods to the reform of Chengdu's public transportation network system. The research results indicate that the integration and coordination of Chengdu's public transportation networks and the rail-bus “dual network” integration have been significantly improved. This provides valuable reference for the systematic construction of public transportation networks and the optimization of hierarchical bus networks in other large cities.
