Smart 15-minute Community Planning
In the post-pandemic era, infectious respiratory disease is still a potential threat to urban health. Research about its transmission is mostly on regional, urban, or indoor scale, while less on community scale. The 15-minute community is a basic unit of urban activities that aims to provide sufficient public and commercial facilities and services within 15-minute walking and cycling distances. This paper aims to investigate the activity connections and pandemic transmission patterns of a typical 15-minute community in Shanghai, and explore planning strategies for enhancing community resilience. According to the GPS trajectory data of survey respondents in a 15-minute community, we identify their activity connection networks. We further simulate how pandemics are transmitted on this network, including the transmission time from each node to the whole network and how this time changes with the intensity of pandemic prevention measures. Based on that, we provide planning strategies for how to find a trade-off point between reducing pandemic risks and maintaining regular activities in 15-minute communities.

Shanghai is actively exploring using Information Communication Technology (ICT) to support 15-minute community planning. This paper reviews recent policies of 15-minute community in Shanghai, introduces the progress of ICT application in Shanghai 15-minute communities, and discusses its future directions. ICT has been applied in Shanghai to provide easier access and improve user experience for public facilities, increase delivery efficiency and enhance space flexibility for commercial facilities, augment physical world and trigger offline activities for urban space. How to use automated, dynamic, and interactive technologies to promote convenient public services, multi-functional commercial properties, and attractive urban space is worth additional explorations.
