Working in partnership with the Atlanta Bicycle Campaign, the PTC has created a bicycle map for commuters to identify the best roads to ride in the Central Perimeter. The good news is that, although there are a few scary roads in the area, there are also some very bicycle-friendly ones, too. The Map Legend will explain how you can tell the difference.

The PTC bike map was generated through an analysis of four components affecting the comfort and safety level of cyclists. These four elements are: 1) traffic speed, 2) traffic volume, 3) road or right lane width, and 4) the frequency of merge lanes, commercial driveways, and "right turn only" lanes. It is assumed that the affected cyclist is familiar with and uses the principles of Effective Cycling.

Obviously, these components will experience some change in nature at different times of the day, or different days of the week. Regardless of the rating of a particular road, the bicyclist should always utilize their vehicular cycling skills, and maintain a high level of caution and awareness. The ratings were compiled through the observations and experience of dozens of area bicycle commuters who ride these roads regularly.

There are three separate elements of the map which can be viewed on this site, or downloaded with Adobe Acrobat. Click on each link below to jump to that feature's page.

These maps show a number of bicycle facility projects that have been slated or proposed in the area. Click here to read in detail about each of them.

Cyclists riding in the Central Perimeter should also be educated about traffic laws that pertain to them, proper vehicular cycling techniques, and the limits and liabilities of the map itself. Click on the links below to jump to each relevant section.

If you like this map, but want something more useful and permanent than the Adobe downloads, Order your own hard copy of this map, printed on waterproof paper. Its free to anyone who lives or works in the Perimeter area, and all it requires is a quick email to the PTC. If you don't live or work here, you can buy a map for $3 from the Atlanta Bicycle Campaign, by calling 404-881-1112.

Rules for Bikes

  • Always remember that all traffic laws which apply to vehicles, but not exclusively to motor vehicles, apply to bicycles. This means that you must obey speed limits, stop signs, and red lights, just as you would if you were in your car.
  • Ride no more than two abreast, but ride single file when traffic gets heavier.
  • Georgia law also states that bicycles should ride as close to the right edge of the road as is practical.
  • The exceptions to the "ride on the right" rule are: when you are trying to make a left hand turn, avoiding hazards, passing another vehicle or when you are in an intersection. Check the details of an Effective Cycling course, but you are generally safer taking a lane while making a turn or passing through an intersection.
  • In practice, this means that you should think of yourself as vehicle on the road, but one that has a right to be seen and acknowledged by other users of the road. Effective Cycling recommends that unless you have at least a three-foot shoulder or a designated bicycle lane, that you ride 2-3 feet from the curb or edge of the grass. You are safest when you are seen, not when cars are trying to squeeze by you as you hug the curb. Understanding how to position yourself in an intersection is an important skill of vehicular cycling, and is taught most clearly in an EC course.
  • See Georgia code sections 40-6-290 through 40-6-299 for details on these and all other laws pertaining to bicycling in Georgia.
  • Bikes are allowed on MARTA trains at all times. See MARTA's website for more details: www.itsmarta.com.

Bicyclists are responsible for their own safety. This map was prepared by the Perimeter Transportation Coalition as an aid to bicyclists riding in the Central Perimeter. The roadways shown on this map are used by automobiles and trucks and typically do not have special facilities for bicycling. The PTC in no way warrants the safety of the streets and bicycle facilities indicated on this map for use by bicyclists, and bicyclists using these roads assume all responsibilities for their own safety. A bicyclist should use these streets and bicycle facilities only if he or she has the requisite skill level as a bicyclist and the bicyclist must make that determination. Bicyclists assume the risk to their own safety when using this map.
