ABSTRACT
With the acceleration of urbanization, traffic demand continues to grow, making the urban expressway system a key focus in research as an essential infrastructure for alleviating urban traffic congestion and improving travel efficiency. This study centers on the optimization of urban expressway systems, aiming to construct an efficient and sustainable expressway network through scientifically sound planning and design methodologies. Methodologically, it first employs big data analytics to deeply explore urban traffic volume, travel characteristics, and spatial distribution, complemented by system dynamics models to evaluate the impact of various design schemes on traffic flow. Subsequently, a multi-ob jective optimization algorithm is introduced, integrating constraints such as capacity, environmental impact, and construction cost to propose a set of expressway planning and design solutions adaptable to complex urban environments. The results indicate that the proposed planning approach significantly enhances the overall capacity of the expressway system while effectively reducing negative impacts on the surrounding environment. Additionally, this study innovatively incorporates intelligent transportation concepts into expressway design through dynamic regulation and real-time monitoring technologies, further enhancing the system's adaptability and flexibility. The primary contribution of this study lies in proposing an integrated planning fr amework that not only provides theoretical support for the scientific design of urban expressway systems but also lays the foundation for the development of future smart transportation systems. The findings offer significant reference value for practical applications in related fields.
