This parallel coordinates visualization displays the randomly selected subset of data (size 2500) from the calls that occured in 2018 as described in the Data and Processing Page. Each line is a call, and the color indicates the hour of the call. If you click on the Legend, calls only from the selected hour are displayed. Priority 2 refers to Non-Emergency Calls, Priority 3 refers to Emergency Calls, and Priority 0 refers to calls with an undeclared/null priority.

At glance, it does not seem as if call priority significantly impacts the response time or hospital travel time. But, at 16:00 and 17:00, it seems that hospital travel time is higher than at other times of day. This may be due to traffic the area. However on average, reponse times and transport times do not seem to vary based on call priorty, which is evidenced by the similar spread patterns along the response time and transport time axes.
