### Web User Interface
At the core of the Summary Panel are several key metrics that capture the essence of emergency performance. These metrics include the Total Emergencies recorded over a specified period, giving users an understanding of the frequency of incidents. The Average Response Time metric highlights the efficiency of the emergency response teams, showcasing how quickly they can react to emergencies. The Total Evacuated metric provides an aggregate count of individuals safely evacuated, reflecting the effectiveness of the evacuation protocols. Additionally, the Critical Incidents metric tallies the number of high-severity incidents, indicating areas that may require more focus or resources. The Summary Panel also incorporates a doughnut chart that displays the types of emergencies. The next component of the page is the Incident Breakdown, shown in Figure 4. It offers a detailed and categorized analysis of various types of emergencies that have occurred. This section is critical for users who need to understand the nature and distribution of incidents within the building or campus. By organizing incidents into specific categories such as fire, medical emergencies, security breaches, and others, this section provides a granular view of the different types of emergencies, allowing users to identify patterns and trends. Each

The statistics table includes counts, averages, and percentages for each incident type, providing detailed insights into the frequency and impact of different emergencies. For instance, users can see the total number of fire incidents, the average response time for medical emergencies, and the percentage of security breaches relative to all incidents. This level of detail helps emergency managers and decision-makers pinpoint which types of incidents are most common and where response efforts may need to be focused or improved. The next component on the page is Response Efficiency, whose UI is depicted in Figure 5. It lists some metrics to evaluate the speed, efficiency, and effectiveness of the emergency response process, offering insights that are crucial for improving future performance and ensuring the safety of occupants. It is designed to help users understand how quickly and effectively their teams are responding to emergencies, identifying strengths and areas for improvement. It is composed of two main parts. The first one visualizes a line chart that shows response times across different incidents. Users can quickly identify patterns, such as the most common response times or outliers where the response was unusually slow. By analyzing these distributions, emergency managers can assess whether their teams are meeting established benchmarks and identify any factors that may be contributing to delays. The second one reports some metrics, instead. The Average Evacuation Time provides the overall average time taken to evacuate people from affected areas, offering insights into the effectiveness of current evacuation plans and protocols. Additionally, the section includes data on Resource Deployment, such as the number and types of resources (e.g., personnel, medical supplies, equipment) utilized during emergencies. This helps users understand how resources are being allocated and whether they are sufficient to meet the demands of different incidents. Lastly, the Success Rate metric, which indicates the percentage of successful evacuations versus unsuccessful or partial evacuations, provides a
