   • 2011, City of Houston, HFD Emergency Medical Services:

     To properly serve the city, ambulance units must be located in a manner that best services all the residents of the city. The location of ambulances is based on the concept of fractal, rather than average response times. Measuring the response time of all sectors of the city derives the fractal response time. Our goal is to have a first responder or BLS on-scene in less than four minutes and an ALS on-scene in less than eight minutes on 90% of all calls.
