### Web User Interface
Another component is the Historical Trends section, situated at the bottom of the Emergency Statistics page, which provides a longitudinal view of emergency data, enabling users to analyze how various metrics have evolved over time, as shown in Figure 6. This section is essential for identifying patterns, assessing the effectiveness of past interventions, and making informed decisions to improve future emergency response strategies. By offering a temporal perspective, the Historical Trends section helps users understand the broader context of their emergency management efforts. The Historical Trends, a line chart visualizing the total incidents per year, represent the main content. Figure 5: Emergency Analysis—response efficiency. Figure 6: Emergency Analysis—historical trends. The following component is the Rooms and Labs Evacuation Times, shown in Figure 7. It provides a detailed overview of the evacuation efficiency for each individual room and laboratory within the facility. This section is crucial for understanding how different areas of the building respond during emergencies, and can highlight specific zones that might need further attention or improvements in evacuation protocols. The information is presented in a clean, tabular format, making it easy for users to quickly identify and compare evacuation times across various rooms and labs. Each row in the table corresponds to a specific room or laboratory, listing the room/lab name and its respective evacuation time. Initially, just a subset of rooms and laboratories are displayed. By clicking the \"View All\" button, users can visualize all the data and have the possibility of ordering and filtering them. This structured layout allows for a straightforward comparison, enabling emergency response teams to pinpoint areas with longer evacuation times and investigate the underlying causes. For instance, if certain labs consistently show longer evacuation times, it may prompt a review of their layout and exit accessibility, or the evacuation training provided to personnel in those areas. This targeted analysis is essential for continuous improvement in emergency preparedness. Finally, the Detailed Reports and Export Options section, depicted in Figure 8, is a powerful feature designed to provide users with comprehensive and customizable reports on emergency data. This section allows users to generate in-depth reports that compile critical information and statistics from various parts of the Emergency Statistics dashboard. These reports are invaluable for post-incident analysis, audits, compliance reviews, and strategic planning, offering a structured and detailed view of emergency management performance. Users can utilize the Report Generation tools to create custom reports based on their specific needs. The interface allows for the selection of various parameters, such as date ranges, incident types, response times, and specific locations within the building or campus. Users can choose which metrics and visualizations to include, such as response efficiency charts, evacuation metrics, and historical trends. This customization ensures that the reports are tailored to meet the unique requirements of different stakeholders, whether they are emergency managers, safety officers, or external auditors. In addition to generating reports, the section provides robust Export Options. Users can export the compiled reports in various formats, including PDF, CSV, and Excel, facilitating easy sharing and further analysis. The PDF format is particularly useful for creating professional and easily distributable documents, while the CSV and Excel

The export functionality also includes options to share reports directly via email or cloud services, streamlining the process of disseminating critical information to relevant parties.
