The influence of "night" factors on urban earthquake disaster prevention

Existing urban planning and urban disaster prevention measures are mostly based on urban space and crowd behaviour patterns during the day, ignoring the anti-disaster demand for urban space at night. Since people's perception of urban space is quite different by night and daytime, with behaviours patterns varying much accordingly, thus the consequences of urban disasters occurring at night are more serious than those occurring during the day, including the trigger of secondary disasters, which are more harmful. This paper collects and analyses the data collected from the target location, and finds that the night factor has a certain degree of impact and change on urban disasters. Through the construction and improvement of disaster prevention lighting facilities, it can guarantee the normal function of evacuation and avoidance paths and areas at night to a certain extent, and help the affected people to carry out effective self-rescue and mutual rescue at night, thereby reducing the impact of disasters and protecting the lives of personnel.
