Analyzing Fire Department Response with PostGIS

Local government fire departments always face scrutiny of their performance and efficiency. They are continuously asked to do a better job with fewer resources. In this highly technical session we will show how PostGIS is being used to analyze and measure performance throughout the city and plan for future resource requirements. Every city we work with is unique in some way. Some fire departments act as the local ambulance service while other cities contract with private ambulance companies. Emergency “911” response centers are often managed by police/law enforcement departments but not always! Many cities also have “mutual aid” agreements with neighboring cities to assist them when needed. For our customers PostGIS stores and manages the geo-located events (fires, hazardous spills, etc.) and provides details about the departments and individual emergency vehicle performance. It is most interestingly used to create statistical reports about things such as “Effecive Response Force” and “Resource Drawdown”, which are used to measure the efficiency and effectiveness of the department. Please come to learn how PostGIS is used to analyze things such as primary response areas and fire hazard severity zones, allowing our customers to ask more advanced, geographically based questions.

Visualizing Fire Department Responses with CartoDB

Local government fire departments need to demonstrate their performance and efficiency. In this session we will show how CartoDB and Torque are being used to visualize fire department responses to emergency events throughout the city allowing city officials to better understand how they are performing. We will also briefly discuss why routing based on Open Street Maps is not yet sufficient enough to be used for this analysis. Effective Response Force (ERF) is one method that fire departments use to measure their level of success. An ERF is a set of specific resources required to perform a particular task within a set amount of time. For example, the Effective Response Force for a residential building fire, which is less than 200 square meters in size, needs to be four fire engines, one ambulance and a fire chief. These resources may be coming from different fire stations; they may be coming directly from other emergency events. They may even come from neighboring cities. Using CartoDB and Torque we can visualize several things; the expected travel routes each of these resources may have taken, compare these routes to expected drive-times based on GIS road network analysis and also show the order in which each of these resources arrived at the destination.
