地铁安检服务时间及其影响因素分析
Analysis of the service time of security check in subway stations and its influence factors

摘要 将乘客通过地铁站安检机的过程细分为放包、走行和取包3个阶段，采集了北京地铁站安检过程的视频数据并进行统计分析，提取可能影响安检服务时间的6个乘客因素和4个环境因素，利用逐步回归的方法提取显著性影响因素.研究发现：行李和安检机类型是影响安检服务时间的最主要因素；年龄、性别、前方乘客类型和数量、结伴、使用手机、运动方式也影响安检过程.通过相对误差对模型进行验证，结果表明：建立的回归模型具有较好的适应性，平均相对误差约为10%.
Abstract：The process of passenger passing security check machine can be divided into three stages being laying down luggage, walking and picking up luggage, respectively. The security check process in Beijing Subway stations is videotaped. Through analyzing the videos, six passenger factors and four environmental factors are extracted, and the significant influencing factors are identified with the step-regression method. It is found that luggage and the type of security check machine are the most important factors. Furthermore, age, gender, type and number of passenger in front, group, using cell phone, and movement mode also affect security process. The proposed model is validated by the relative error. Research results indicate that the proposed regression model has a good adaptability and the mean relative error is about 10%.
