无信号控制路段手机对行人过街行为和安全的影响

行人过街时使用手机会对其过街行为和交通安全产生一定的影响.本文以武汉市6个无信号路段交通调查数据为基础，对行人使用手机时的行为和安全性进行统计分析，并建立了基于Order Probit回归分析的人车冲突量化模型.结果表明：11.76 %的行人在过街时会使用手机，其中看手机屏幕、打电话和听音乐分别占6.65 %、2.83 %和2.28 %；使用手机对行人过街行为有明显影响，包括行人过街时间增加、过街眺望次数减小等；与不使用手机的行人相比，行人使用手机会有更大的几率与机动车产生冲突，其中，打电话对是否产生轻微冲突的影响最大，看手机屏幕对是否产生严重冲突的影响最大.

The Effects of Mobile Phone on Pedestrian Crossing Behavior and Safety at Uncontrolled Mid-block Crosswalks

Using mobile phone may have effect on pedestrian crossing behaviors and traffic safety. Based on the data, which collected from six uncontrolled mid- block crosswalks in Wuhan city of China by field survey, the paper establishes the pedestrian- vehicle conflict analysis model based on Order Probit regression analysis. The results show that: 11.76% of pedestrian used the mobile phone when crossing streets. Among them, staring at the mobile phone, making phone calls and listening to music on their mobile phones account for 6.65%, 2.83% and 2.28%, respectively. Moreover, using mobile phone has obvious impacts on their crossing behaviors. When using the mobile phone, pedestrian spent more time getting through the street, and looked around less often, etc. Furthermore, PVCA model indicate that pedestrian who using mobile phone had significantly greater chances to conflict with vehicles than those who do not use it. For example, talking on the mobile phone has the biggest influence on slight conflict, and staring at the mobile phone has the largest impact on serious conflict.
