If your supervisor allows you, consider leaving earlier for work. Ask if you can shift your hours so that you arrive for work earlier in the morning and leave earlier in the afternoon. I understand that some occupations or day care schedules may not permit any deviation, but some people can make the switch.
There are a few benefits to leaving for work when it's still dark. First of all, traffic is much lighter the earlier you leave your home. Even a change in 30 minutes can be a noticable difference. If you are not stuck in heavy traffic, your car will be saving fuel.
Another benefit is the coolness of the morning. Even though daytime temperatures in North Georgia in the summer average in the mid 90s, the morning temps are in the seventies. You do not have to run your air conditioner in cooler temperatures.
