In Figures 3-2, 3-4, 3-6, and 3-8, the patrol resources available are denoted by the dashed green line
at the top. The 100 percent value indicates the total police officer hours available during the 24-
hour period. This amount varies during the day consistent with the staffing of the shifts, but at any
given hour the total amount of available manpower will equal 100.
The red dashed line fixed at the 60 percent level represents the saturation index (SI). As discussed
above, this is the point at which patrol resources become largely reactive as CFS and workload
demands consume a larger and larger portion of available time. The solid black line represents total
workload experienced by the MHPD.
Figures 3-1 and 3-2 present the patrol workload demands and SI for weekdays in winter 2015. As
the figures indicate, the 60 percent threshold is not surpassed during the day. The SI ranges from a
low of approximately 5 percent at 7:30 a.m. to a high of 57 percent at 2:45 p.m., with a daily average
of 41 percent.
Figure 3-1 illustrates many interesting facts about patrol deployment in the MHPD. During this
period, it appears that the department has a steady deployment of officers throughout the day. Both
day and night shifts assign between four and six officers on average, with additional personnel
working predominantly between 7:00 a.m. and 7:00 p.m., with fewer additional personnel working
after midnight.
The blue area in Figure 3-1 represents CFS demand from the public. This figure clearly shows that
public demand for police resources is easily met by the patrol staffing deployed. Adding the police-
initiated and directed patrol workloads to the workload from public demand still does not
challenge the department’s ability to meet service levels. The gray areas represent out-of-service
time, and as the figure illustrates, this peaks before the end of each shift, presumably when the
officers are completing their paperwork before the work day ends.
