VEHICLES._AN,D_ACC_tDENTS <br />The number of registered vehicles in Orange County has kept pace with population <br />increases. In 1980, there were 45,046 vehicles registered in the County. By 2000 that <br />number had increased by more than 33,000 to 78,177 registered vehicles. By 2005, <br />there were 84,983. Registered vehicles increased by 88% between 1980 and 2005. <br />Traffic accidents in the County increased by 69% over this same period, showing that <br />there have been fewer traffic accidents per registered vehicle over time. See Figure 9-5. <br />11 <br />FIGURE 9-5: REGISTERED VEHICLES AND TRAFFIC ACCfDENTS IN VEHICLE <br />ORANGE COUNTY (1980-2005) AIR <br /> <br /> <br />Year Auto/ <br />Truck <br />Regs2 <br />Traffic <br />Accidents3 <br />1980 45,046 1,695 <br />1990 63,711 2,018 <br />2000 .78,177 2,715 <br />2001 80,101 2,927 <br />2002 81, 390 2, 874 <br />2003 82,093 3,034 <br />2004 83,886 2,799 <br />2005 84,983 2,875 <br />Notes and Sources: <br />T NC Department of Transportation <br />2 Actual registrations for automobiles and trucks for the calendar <br />year in which the vehicles were registered. <br />3 A reportable accident is one that involves a motor vehicle <br />resulting in injury, death, or total property damage of $1,000 or more. <br />Source: Appendix A: County Profile (Data) Element <br />EMISSIONS <br />Inventories of local air emissions show that mobile uses (i.e., automobiles, trucks, other <br />vehicles) were the primary generator of non-point source carbon monoxide (CO) <br />emissions in the County. In 2000, mobile sources (e.g., automobiles, trucks) generated <br />almost 60~ of carbon monoxide (CO) emissions, and almost 80% of nitrogen oxides. <br />Non-road emissions (e.g., lawn mowers, outboard engines, and agricultural equipment) <br />were also a significant source of pollutant emissions during this period. Together, these <br />two sources are the primary generators of carbon monoxide and nitrogen oxide <br />emissions in the County. Projections by the North Carolina Department of Air Quality <br />suggest that total emissions will decrease over time, and that mobile and non-road <br />vehicles will continue to be the primary sources.
