Research on the Process Efficiency of Metro Security CheckSystem Under the Perspective of Spatial Guidance

Metro is one of the most important forms of public transportation in Chinese cities. With the continuous expansion and development of metro networks in China's major cities, ensuring the safety of passengers has become a key part of metro operation and management. However, there are some efficiency and human factors engineering deficiencies in the current metro security system. Some researchers have studied the efficiency of subway security systems and their influencing factors in subway or railroad stations. However, in actual subway stations, the spatial guidance in front of and behind the screening area is also one of the causes of congestion in the screening area. This study focuses on the deficiencies of spatial guidance in the subway, and the resulting congestion in the subway station, which leads to a reduction in the efficiency of the screening system. The implementation plan of this study is to explore the spatial guidance system of Guangzhou Metro, summarize the influencing factors of congestion, quantify and extract data for the influencing factors, and establish a model and data analysis. The interview method was used to invite volunteers to participate, and the information from the interviews was used for data statistics to quantify the influencing factors caused by the spatial guidance system, to establish an appropriate model for the influencing factors, and to determine the significant influencing factors of the spatial guidance on the congestion of people with respect to the data fed back from the model. The collected data and information are coded using the rooted theory research method, analyzed with the help of auxiliary software, and finally, three categories of first-level core influence factors of site layout design, guide signs, and human factors and corresponding second- and third-level subcategories are refined, and a system of influence factors on the efficiency of the process of the security system under the perspective of spatial guidance is constructed.
