Description
With the intensification of global climate change and energy crises, green and low-carbon development has become a core objective of urban planning. As a critical component of urban green transportation systems, slow traffic networks can not only reduce carbon emissions but also enhance residents' quality of life and travel experience.
The spatial structure of all landscapes is composed of three fundamental elements: patches, corridors, and matrices, known as the "Patch-Corridor-Matrix" model. Ecological networks use various corridors to organically connect landscape patches, forming a continuous spatial structure that emphasizes the structural and functional relationships between patches, corridors, and matrices. Similarly, an urban slow traffic network organizes public space resources through slow traffic pathways and integrates public service facilities into a network system of areas, lines, and nodes, demonstrating a comparable spatial organizational logic to ecological networks.
Currently, urban slow traffic networks face issues such as lack of systematic organization, poor continuity, insufficient consideration of ecological values, and single functionality, etc. This study takes the central urban area of Shanghai as the research object. Inspired by the network model and construction methods of landscape ecology, it selects multidimensional resistance indicators for slow traffic. By calculating the optimal experiential slow traffic corridors, the study constructs a systematic urban slow traffic network from the perspectives of areas, lines, and nodes, ensuring traffic efficiency while addressing the issue of single functionality.
(1) Areas: Identification of Slow Traffic Patches
Using Morphological Spatial Pattern Analysis (MSPA), the study scientifically identifies and classifies natural resources (e.g., green parks, water bodies) and cultural resources (e.g., commercial centers, cultural heritage sites, public spaces). Key patches, such as core areas and edge zones, are extracted to provide foundational nodes for the slow traffic network.
(2) Lines: Construction of Slow Traffic Corridors
Located on the East China Plain, Shanghai's natural resistance to walking and cycling is relatively low, making the built environment the primary influence on slow traffic resistance. Based on domestic and international studies on walkability, this research selects slow traffic indicators from five dimensions: greenery, health, vitality, equity, and safety. A slow traffic resistance index is developed, with indicator weights determined using the entropy method.
The Minimum Cumulative Resistance (MCR) model is employed to construct a resistance surface for Shanghai’s slow traffic network, identifying corridors with the lowest cumulative resistance. These corridors represent streets with potential for ecological prioritization, spatial comfort, vitality, accessibility, and safety.
(3) Nodes: Design of Slow Traffic Stepping Stones
Inspired by commonly used landscape ecology indices, including the alpha index (network closure index), beta index (node connectivity), and gamma index (network connectivity), this study calculates the cyclic and connective relationships between nodes and corridors based on spatial topology. Slow traffic stepping stones are designed in areas with low network connectivity.
In ecology, stepping stones serve as intermediate stations for species migration. Similarly, slow traffic stepping stones are designed as small public spaces or service facilities that provide rest areas and enhance connectivity between large patches. This increases activity frequency for residents traveling between slow traffic patches.
This study innovatively incorporates ecological theory into the construction of urban slow traffic systems. By integrating natural and cultural patches with scientifically designed corridors, it addresses the lack of systematic planning in current slow traffic corridor development. Furthermore, it expands the scope of slow traffic systems from a single transportation function to include multiple dimensions such as ecological services, cultural exchange, equity, and inclusivity, etc. The research provides both practical examples and theoretical support for urban green and low-carbon development, offering a reference model for the planning of slow traffic systems in other cities.
