With the intensification of global climate change, construction of low-carbon cities and carbon neutrality have become a priority for the world. In the ranking of industrial carbon emissions, urban transportation remains high and has become the main target in battle with carbon emission. Walking is an integral part of urban transportation and is considered the most energy-saving way. Accordingly, the quality of pedestrian environment will directly affect people’s inclination for travel methods. Therefore, it can be concluded that the construction of pedestrian environment has profound significance for the development of low-carbon transportation. Due to its early construction, the design of old communities can poorly coordinate the living needs in new era.
