防止新冠疫情扩散的城市交通系统与出行活动管控策略

This research proposes in an integrated framework a set of network-wide management and control strategies on transportation systems and travel activities for the epidemic intervention and control and discusses the implementation issues and methods of this strategies. The strategies could be categorized into four groups: ① travel demand management (including compulsory and advisory demand management strategies); ② transportation system control (limiting or adjusting the operations of certain transportation modes, facilities and areas in space and time); ③ travel population screening (quickly identifying those virus infectors from the travel population and tracing their activity trajectories in an urban transportation system or network); ④ quarantine facility planning (for isolating, accommodating, monitoring, inspecting and curing suspected or infected cases). The focus of this paper is on a discussion of the rationale, purpose and efficacy of these strategies, along which the resulting technical problems, data requirements and solution methods for implementing these strategies are briefly suggested as well.
