Illinois Data Summary
Overall, from 2000 to 2003, DVCs represented approximately 5.2 percent of all the crashes reported and summarized in Illinois. The total number of DVCs has also increased during the last decade. An evaluation of the Illinois DVC-related data showed the following general patterns:

• The annual total number of crashes reported and summarized in Illinois has generally increased throughout the decade, but appears to have decreased somewhat from 2000 to 2003 (See Figure 1). The AVMT in Illinois has consistently increased during the study time period (See Figure 2).

• There was an increasing trend in the annual number of DVCs reported in Illinois for the years summarized (See Figure 3). The number of DVCs reported ranged from 16,504 to 25,660 during this time period (a 55.5 percent increase). The increase in reported DVCs from 2000 to 2003 was 30.0 percent. The percentage of total crashes represented by DVCs has also increased (See Figure 4). From 2000 to 2003 this measure increased from 4.29 to 5.87 percent.

• The annual number of fatalities due to DVCs ranged from 1 to 6 between 1993 and 2003. There were a total of 36 DVC fatalities during these 11 years. The number of injuries due to DVCs ranged from 778 to 1,245 for those years in which all non-fatal DVCs in Illinois were summarized (i.e., 1993 to 1995 and 2000 to 2003). The number of fatalities and injuries during the last decade appear to vary from year to year with an increase from 2000 to 2003 (See Figure 5).

• The DVC rate (i.e., the number of DVCs per HMVMT) has also increased from 1993 to 2003 despite the constant increase in AVMT. This measure has ranged from 18.4 DVCs per HMVMT in 1993 to 24.1 DVCs per HMVMT in 2003 (a total increase of about 31 percent).
