With the acceleration of urbanization, the traffic pressure on urban roads has increasingly grown, leading to problems such as traffic congestion and low road efficiency (traffic efficiency). Therefore, how to optimize traffic organization during urban road reconstruction and expansion to improve road capacity and traffic efficiency has become a key issue requiring urgent solution. This paper conducts research on traffic organization optimization strategies for urban road reconstruction and expansion, proposes various effective optimization methods—including traffic flow analysis, application of intelligent transportation systems, and intersection design optimization—and analyzes them through specific cases. Through optimizing traffic organization, it is possible not only to improve traffic conditions but also to effectively reduce urban environmental pollution and traffic accidents, thereby promoting sustainable urban development.
