Georgia DOT is making every effort to keep traffic moving smoothly in our state, but delays are inevitable. You can manage your commute and reduce the number of vehicles on our roadways by exploring alternatives to driving during peak traffic hours. There is no better time to try commute options that will make getting to and from work easier.

Alternative Commute Options

The following is a list of alternative commute options that can help reduce the amount of smog produced by vehicle emissions.

  • Carpool or Vanpool: Call 1-87-RIDEFIND, or ask about your employer's carpooling programs.
  • Mass Transit: Commute to work utilizing the train or bus service in your community.
  • Telework: Work at home using your phone, fax, and computer.
  • Flex Hours: Adjust work schedule to commute when traffic is less congested.
  • Compressed Work Week: Work a four day work week made up of 10 hour days.
  • Ride a Bike: Adjust work schedule to commute when traffic is less congested.
  • Walk: Walk to work and to lunch if possible.
  • Use Technology: Instead of driving to meetings, schedule conference calls, use e-mail and fax to communicate with clients, co-workers, and vendors.

Congestion Mitigation and Air Quality Improvement Program (CMAQ)

The CMAQ Program provides funding assistance to areas designated as non-attainment by the EPA. Areas failing to meet the NAAQS receive funds to invest in projects that decrease transportation-related air pollutants. The FHWA and FTA jointly administer this program to allocate funding to state DOTs and MPOs based upon the severity of congestion and population within the non-attainment areas. These funds are spent on specific transportation projects that decrease emissions and improve congestion.

CMAQ Call for Projects

State air quality agencies, along with local MPOs, select projects through an application process. Counties, municipalities, state agencies, and universities are permitted to submit applications. All applications are reviewed for eligibility as well as effectiveness on emissions reductions.


Tips to Reduce Smog

  • Don't Top Off: When pumping gas, don't overfill. This will prevent smog producing fumes from escaping into the air.
  • Late Start: Plan the use of gas-powered lawnmowers, blowers, edgers, chainsaws, and other motorized equipment for cooler evening hours. Refuel vehicles at dusk during cool hours.
  • Watch Your Temp: Set household thermostats at 78 degrees in summer and 68 degrees in winter.
  • Drive in Stride: Drive at a moderate speed; avoid quick take offs and stops.
  • Reduce Car Idling: Idling for extended periods at a drive-through or in traffic creates harmful pollutants. Park, and go inside.
  • Car Care: Get regular tune-ups, inflate tires properly, keep wheels aligned, and replace dirty air filters.
