This chart displays the average time it takes for emergency responders to become available again after arriving on scene,
organized by incident type.
Train and rail incidents seem to take the longest to resolve, followed by building fires
and water rescues. However, note that because of the large differences in sample sizes, the data shown may be inaccurate for
certain types of incidents.
This chart displays the number of occurences of each incident. Click on the labels to toggle each type of incident.
The incident that overwhelmingly occurred the most was medical emergencies, followed by alarms and building fires.
This graph displays the number of occurences of a certain incident type throughout the day. Again, due to the smaller sample sizes for some incidents, there may be insufficient data for certain incident types to draw any meaningful conclusions. However, there are some interesting trends that can be seen from this data; for example, there is a noticeable increase in traffic collisions around 8AM and 5-6PM when people are going to and from work.
Given an address and time, this attempts to predict the most likely dispatch that would be sent to that area as well as the most likely emergency that would occur.
To the left is a graph displaying the average amount of time it takes to get to an emergency sorted by zipcode. The zipcode with the longest dispatch time is 94130, followed by 94131 and 94105. These are Treasure Island, the Twin Peaks area, and the Rincon Hill area respectively.
The most obvious solution for improving dispatch times would be creating more stations around the city, especially in denser parts
of the city such as the downtown area. However, other solutions may lie in improving traffic flows across the city so that
emergency vehicles can get to places more rapidly or creating more access points to locations by building more roads.
To the right, a heatmap of all incidents is shown. It's clear that most of the emergencies occur in the downtown region of San Francisco, so while it is important to have enough stations there to service the massive population in that region, it is also important not to neglect the outer regions as there is still a need for strong dispatch centers, indicated by the pockets of activity on the heatmap outside of the downtown area.
