1993 to 2003 the average percentage of all crashes reported in Michigan
that were DVCs was approximately 15.6 percent. This is the largest percentage
of DVCs found in the five states considered in this report. An evaluation
of the Michigan DVC-related data showed the following general patterns:
The annual total number of crashes reported and summarized in Michigan
has been relatively stable between 1993 and 2003 (See Figure 1). This
safety measure has fluctuated between 350,000 and 450,000 for this time
period. The largest annual number of reported crashes was in 1996 at 435,477,
and the smallest number occurred in 1993 at 363,636. The AVMT in Michigan
was stable from 1993 to 1995 and 2002 to 2003, but increased steadily
between these two time periods (See Figure 2).
• The annual number of DVCs reported in Michigan increased from
47,812 in 1993 to 68,233 in 1996, but this measure has only ranged from
63,136 to 68,233 between 1996 and 2003 (See Figure 3). The percentage
of total crashes represented by DVCs has increased from 13.2 percent in
1993 to 17.3 percent in 2003 (See Figure 4).
• The annual number of fatalities due to DVCs ranged from 2 to 11
between 1993 and 2003. There were a total of 67 DVC fatalities during
these 11 years. The number of injuries and fatalities due to DVCs in Michigan
increased from 1993 to 1998, but has seen a decrease from 1998 to 2003.
However the largest annual number of reported DVC fatalities occurred
in both 2001 and 2003.
• Similar to the number of DVCs reported, the DVC rate (i.e., the
number of DVCs per HMVMT) increased from 1993 to 1996, but between 1996
and 2003 the annual number of reported DVCs has been relatively stable
and the statewide DVC rate decreased slightly. The Michigan DVC rate peaked
at 77.8 DVCs per HMVMT in 1996 and was at 69.0 DVCs per HMVMT in 2003.
• Michigan also provided annual deer population estimates from 1993
to 2003. Figure 7 shows that the annual pre-hunt deer population estimates
increased from 1,630,000 in 1993 to 2,171,000 in 1995 (a 33.2 percent
increase), and then generally decreased from that point to 1,776,000 deer
in 2003 (an 18.2 percent decrease in eight years). The number of carcasses
removed from the roadside in Michigan was not provided and does not appear
to be summarized in the state.
