INTERPRETATION The model assumes: • A fixed"startup"time of 0.65 minutes (--39 seconds). • After that, each additional mile adds 1.7 minutes (--102 seconds). • This makes the model simple, predictable, and easy to apply for planning station locations, estimating response times, and evaluating fire-protection coverage. Origin and Citation The formula is widely attributed to the Insurance Services Office (ISO), which incorporated it into its Fire Suppression Rating Schedule (FSRS). ISO cites the RAND Corporation's early fire-travel research as the basis for the constants. ISO Properties, Inc. (2007b). Fire Suppression Rating Schedule: Technical documentation. ISO Properties, Inc.,p. 1. Background: Why It's Called the "RAND Equation" The equation is based on research originally conducted by the RAND Corporation in the 1970s, which analyzed fire-engine travel times in major cities. RAND researchers found that: Travel time increases approximately linearly with distance. A fixed acceleration component plus a constant per-mile travel time best fit observed data. ISO later adapted and standardized this model for national use. 8. Comparison to Fire Service Provided by Hays County Emergency Services District No. 5 The City of San Marcos has also evaluated the potential implications of fire protection services being provided by Hays County Emergency Services District No. 5 in areas adjacent to or surrounding the City.Based on available information regarding ESD#5's deployment and service area, the City finds that reliance on fire protection resources primarily positioned to serve areas outside the City could result in reduced response efficiency when compared to the City's existing fire service model. Hays County Emergency Services District No. 5 operates fire stations and apparatus positioned to serve its designated district, which includes rural areas and developing portions of Hays County outside the City of San Marcos. Because these resources are deployed to meet service demand within the district's broader coverage area,their availability to respond to incidents within the City may be influenced by unit status,travel distance, and concurrent incident activity. As a result, incidents occurring within San Marcos could experience longer response intervals when compared to a system in which fire stations and apparatus are located within the City and dedicated to serving the San Marcos community. In contrast, the San Marcos Fire Department maintains stations strategically distributed throughout the City, allowing fire apparatus and personnel to respond rapidly to emergencies within the community. In addition to response time considerations, fire service operations within the City are closely coordinated with emergency medical services and law enforcement through shared communications infrastructure,unified dispatch procedures,and established operational protocols.
