Indicator: Ozone Parts Per Million (PPM)
Are motor vehicle emissions decreasing per capita?
Notes: Ozone is created by a chemical reaction between Nitrogen Oxides (NO) and Volatile Organic Compounds (VOC). NO and VOC emissions occur from multiple sources including aircraft, trains, boats, lawnmowers, cars, trucks, and manufacturing facilities. In 2006 in Shelby County, vehicle emissions (cars and trucks) counted for 25% of VOC and 56% of NO. This number is projected to decrease to 12% and 28% respectively by the year 2021. The data source is the Shelby County Health Department.
Indicator: Total Number of Crashes
Is the number of traffic crashes decreasing?
Notes: The period data sets are not to be considered final as crash reports may continually be reported into the system for an extended time frame. Tennessee's crash data is obtained through the Tennessee Integrated Traffic Analysis Network (TITAN) and Mississippi's crash data is reported through MDOT. The county-wide crash data will be updated on a quarterly basis.
