最近的研究报告说，分心行走造成的事故数量显着增加。在本文中，我们开发了一个移动的系统，提供了一个及时的警告行人和司机，以减少涉及交通事故的机会。所提出的系统进行行人风险评估，估计碰撞概率的基础上准确的用户定位，用户手机观看事件检测，和基于WiFi P2P的车辆到行人的通信。根据产生的碰撞概率，警告行人（和驾驶员）以防止事故。所提出的系统是在COTS智能手机上实现的，并在一个部门的停车场进行实验。实验结果表明，它有效地计算碰撞概率，并相应地发送警报消息，以及时的方式向用户利用其提高定位精度，能源效率，和有效的用户上下文感知。
Recent studies reported a significant increase in the number of accidents caused by distracted walking. In this paper, we develop a mobile system that provides a timely warning to the pedestrian and the driver to reduce the chance of pedestrian-involved accidents. The proposed system performs pedestrian risk assessment to estimate the collision probability based on accurate user localization, user-phone-viewing event detection, and WiFi P2P-based vehicle to pedestrian communication. Depending on the resulting collision probability, the pedestrian (and the driver) is alerted to prevent accidents. The proposed system is implemented on a COTS smartphone, and experiments are conducted in a department parking lot. Experimental results demonstrate that it effectively calculates the collision probability and sends accordingly an alert message to the user in a timely manner leveraging its improved positioning accuracy, energy efficiency, and effective user context awareness.
