沪崇越江通道与上海北部地区高快速路网的功能协同研究

Study on Functional Coordination between the Shanghai-Chongming River-Crossing Corridor and the Expressway & Arterial Road Network in Northern Shanghai

摘要: 在长三角一体化与上海“北转型”战略背景下，上海北部地区(嘉定、宝山等)的高快速路网面临客货混行、过境交通集聚、路网饱和等结构性挑战。本文系统分析北部地区路网现状矛盾，并重点探讨S7沪崇越江通道在区域路网功能重构中的关键作用。研究认为，S7通道不仅是缓解沪崇越江单一瓶颈的关键工程，更是构建北部地区“三环、一纵、四射、多联”高快速路网格局的重要组成。通过与S22嘉安高速、G1503北切线等规划通道协同，该通道有望促进客货分流、过境外移与流量均衡，从而为上海北部地区及长三角北翼的高质量发展提供交通支撑。

Abstract: Against the backdrop of the Yangtze River Delta Integration and Shanghai’s “Northern Transformation” strategy, the expressway and arterial road network in northern Shanghai (including Jiading and Baoshan districts) is confronting structural challenges such as mixed passenger and freight traffic, concentrated through traffic, and network saturation. This paper systematically analyzes the current contradictions of the road network in the northern region and focuses on exploring the key role of the S7 Shanghai-Chongming River-Crossing Corridor in the functional restructuring of the regional road network. The study concludes that the S7 Corridor is not only a crucial project to alleviate the single bottleneck of river crossing between Shanghai and Chongming but also an important component in constructing the “Three Rings, One Vertical, Four Radiations, and Multiple Connections” expressway and arterial road network pattern in the northern region. Through coordination with planned corridors such as the S22 Jia’an Expressway and the G1503 North Tangent Line, the corridor is expected to promote the separation of passenger and freight traffic, the diversion of through traffic to the periphery, and traffic flow balance, thereby providing transportation support for the high-quality development of northern Shanghai and the northern wing of the Yangtze River Delta.
