Produced by SFOpen Data, the Fire Department Call for Service data set contains fire unit responses to calls in December, 2016. It includes information pertaining to the call type, the exact call date, the neighborhood/district of the call, and more. It essentially contains everything you would want to know about calls for service to the SFFD from December 1st to December 31st, 2016.

Our group, P3, focuses on a subset of the original data. We hope to highlight any alarming or intriguing patterns that occur around the school that we attend every day. Therefore, our data limits its selection to the five neighborhoods/districts closest to the University of San Francisco by modifyin based on the Neighborhoods..District variable. The five closest neighboring districts are Haight/Ashbury, Inner Richmond, PresidioWestern Addition and Lone Mountain/USF.

Within each district, we focus on the time it takes for a call to be responded to by taking the difference between the following two date variables: Response.DtTm and Received.DtTm. Within this dataset, 2.3% of the observations did not have a Response.DtTm value. In order for us to make calculations we refined our dataset by including only those observations where the response times were logged. This data can be observed in the Heat Map below. We also utilize the Call.Type.Group variable which contains the following levels:

Our final working dataset contains 4 columns and 2153 rows.

Small Multiples Bar Graph

This visualization uses grouped bars to analyze the types of calls that are placed in these specific districts. The types of calls placed are categorized as “Alarms”, “Fire”, “Non Life-Threatening” and “Potentially Life-Threatening”. To distinguish the call types they each are given a different color in the visualization. The bar height measures the percentage of calls for that specific type were placed in the given district. Each district follows a similar trend where “Fire” calls occur the least, followed by “Non Life-Threatening”, “Alarm” and “Potentially Life-Threatening” in that order. The distinguishing district however is Presidio where “Fire” calls are placed the most. This is probably due to their dense tree population, that differs from the rest of San Francisco.

Multiline Chart

Using a subset from the San Francisco Fire Department Calls for Service data set, this prototype concentrates on the four flanking neighborhoods that surround the University of San Francisco (Haight Ashbury, Western Addition, Inner Richmond, Presidio) to include USF/Lone Mountain. The graph is a breakdown of the amount of service calls pertaining to "Potientially Life Threatening" and "Non-Life Threatening" events throughout the month of December 2016. Event activity is separated by neighborhood with the bottom of the y-axis representing no activity and the top representing the maximum activity. Likewise with the x-axis; left to right in a linear fashion.

Heat Map

Focusing on the the five districts around the University of San Francisco, this prototype highlights the average response time for calls to the SFFD. It calculates average this measure in minutes, subtracting the response time from the received time of each call. Also, the heat map plots these response hour per hour in an everage December day in 2016. Next, the heat map uses a diverging color sequence to encode data. Dark red colors signal slow response times. Light red colors clue quick response times. Overall, it seems that the slowest times occur around 4-6pm, perhaps because the most calls happen in the late afternoon and early evening.
