The A-TRAIN Trip Planner is an interactive online utility provided to help Atlanta residents and visitors get around the city by foot, bicycle, and transit.

This resource is produced and maintained by volunteers from Citizens for Progressive Transit, a non-profit advocacy organization, as a non-commercial, open-source project. Initial funding for the project has been provided by Friends of the Earth.

How the Trip Planner Works

The goal of this utility is to give users maximum flexibility in planning car-free trips around Atlanta. Users specify their start and end locations, a departure or arrival time, and any other preferences relevant to the specific type of trip. Currently, four trips types are supported:

1. Walk-Only Trips: These trips are completed entirely on foot, and are the simplest type of trip in terms of user input into the utility; in addition to start/end locations and time, the only variable is walking speed. This option will return the shortest trip possible using walkable facilities, which is defined to include all publicly accessible roadways and footpaths other than those where pedestrian traffic is expressly forbidden (e.g. expressways). Currently, no consideration is made for the specific level of pedestrian accommodations on a walkable facility; this feature may be added in a future version.

2. Bike-Only Trips: These trips are completed entirely by bicycle. When this option is selected, the utility will find the optimal legal route between two points based on user-specified cycling preferences. It is assumed that the cyclist will always ride in the street (it is against the law in Georgia for adults to ride on the sidewalk) and will observe one-way street restrictions and other traffic regulations.
