An inexpensive and robust 3D localization system for tracking the position of a user in GPS‐ or WLAN‐denied environments offers significant potential for improving decision‐making tasks for civil and infrastructure engineering applications. To this end, an infrastructure‐free approach for 3D event localization on commodity smartphones is presented. In the proposed method, the position of the user is continuously tracked based on the smartphone sensory data (the Forward approach) until the user reaches a certain event. Here, an event location refers to the 3D location of a user conducting value‐added activities such as tasks involved in emergency response and field reporting of operational issues. Once an event is observed, the motion trajectory of the user is backtracked from the postevent landmark to reestimate the location of the event (the Backward approach). By integrating probability distributions of the Forward and Backward approaches together, the proposed method derives the most‐likely location of the event. To validate the proposed approach, seven case studies are conducted in a multistory parking garage. The experimental results show that the probabilistic integration of the localization results from the Forward and Backward dead reckonings can produce more accurate 3D localization results when compared to a single best estimate from a one‐way dead reckoning process. Lessons learned from several real‐world case studies and open research challenges in improving localization accuracy are discussed in detail. 相似文献

Recent disasters have shown that road tunnels are especially complex environments for decision making. A fast and effective response to emergencies in road tunnels is a key factor for life safety. This paper presents a decision support system (DSS) for emergency management in road tunnels. Based on a specific methodology, the system provides the operator with decision recommendations to deal with the emergency in real time. Furthermore, the system uses predictive tools to estimate the severity of the accident or incident, as well as rescue and evacuation times. This information is very useful during the first stages of an emergency when information is scarce, incomplete and inaccurate, yet the tunnel operator is required to make the right decisions under a high level of stress. The DSS reduces the decision circle and allows the operator to make critical decisions based on dynamic alternatives. The system has been tested in various hypothetical emergency cases based on the Tunnel of Lantueno in the A-67 Highway, Spain. The application cases show that the DSS provides reasonable and consistent results. 相似文献
