About atltransit.live

Not affiliated with MARTA. atltransit.live is not affiliated with, endorsed by, or sponsored by the Metropolitan Atlanta Rapid Transit Authority (“MARTA”) or any local, state, or federal government entity. All transit data is sourced from MARTA’s publicly available GTFS and GTFS-RT feeds (its standard schedule and real-time-data formats) and public service alerts. “MARTA” and related marks belong to the Metropolitan Atlanta Rapid Transit Authority; we reference them only to describe the system this site covers.

atltransit.live tracks MARTA buses and trains in Atlanta in real time. It grew out of marta.fail, which started as a way to push MARTA service alerts to Bluesky. atltransit.live adds a live map, arrival predictions, route statistics, and optional notifications.

MARTA already publishes this data, but it’s spread across PDFs and several separate pages. This site puts it in one place.

What you can do here

  • See live vehicle positions and predicted arrivals for MARTA bus and rail routes.
  • Browse route maps and service statistics, including how often a given route has been affected by delays or disruptions.
  • Follow service alerts for the routes you actually ride, instead of scrolling through everything.
  • Save favorite stops and routes, and opt in to email or push notifications when something changes, no account required.
  • Register for a developer account to access our API and build on our data.

No account is needed for the core site, including saving favorites and notifications. An account is only required for developer/API access.

Our approach to data

We combine and clean up data MARTA already makes public. We don’t editorialize service alerts, and we don’t claim to be more accurate than MARTA’s own systems. When our data and MARTA’s official channels disagree, MARTA’s official channels are the source of truth. See our Terms of Service for the full disclaimer on data accuracy.

Frequently Asked Questions

Is this an official MARTA app or website? No. atltransit.live is an independent project operated by Civic Forge Solutions LLC (CFS). We’re not affiliated with, endorsed by, or sponsored by MARTA. For official information, always check itsmarta.com or MARTA’s official rider apps, especially for anything time-sensitive or safety-related.

Who do I contact about issues with MARTA’s service? Contact MARTA directly. atltransit.live only republishes information MARTA already makes public; we can’t change MARTA’s schedules or service levels, and we can’t resolve complaints about MARTA’s actual service. Reach MARTA through itsmarta.com or MARTA’s official customer service channels.

Where does your data come from? All schedule, real-time position, and alert data comes from MARTA’s public schedule and real-time-data feeds (GTFS and GTFS-RT) and public alert channels. We fetch, clean up, and display this data. We don’t generate it ourselves.

How accurate are the real-time arrival predictions? They’re only as accurate as the underlying MARTA data feed, plus any latency in how quickly we can process and display it. Predictions are estimates, not guarantees. If a prediction seems off, MARTA’s official tracker or in-station signage is the more authoritative source in the moment.

Do I need an account to use the site? No, not for the core site. The live map, arrivals, route maps, and service alerts are open to everyone with no account required, and saving favorite stops/routes or opting into email/push notifications doesn’t require one either. An account is only needed to access our developer tools, including the API.

Why do you charge for developer access? Developer access requires additional resources to maintain: sustained polling of MARTA’s real-time feeds, higher-volume infrastructure, rate-limit enforcement, and support for apps built on our data. Charging for developer/API access lets us keep the core site free for everyone while covering the cost of supporting third-party developers.

Can I build an app based on the developer data? Under our Data License, you may build apps (web, iOS, iPadOS, Android, etc.) for personal, non-commercial use, with attribution to atltransit.live.

If you publish an app on an app store that uses data from atltransit.live, and/or charge for use of the app, that counts as commercial use. Commercial use requires a separate license agreement with CFS. Email [email protected] to discuss one.

Can I use your data in my own project? Where we publish aggregated or processed data for reuse (such as a public API or dataset), it’s offered under our Data License. You may share and adapt it non-commercially with attribution to atltransit.live. See the Data License for the full terms, including the academic/journalism exception and any API-specific rules. For commercial use, email [email protected] to discuss a license.

If you’re using public data, why do you have a restricted license on it? Why is a commercial license needed to build an app? Why are you charging for the API? The source data is free to acquire, but turning raw data into something useful isn’t. Polling, storing, and analyzing live MARTA data takes computing resources. Building the pipelines, the statistics, and the site itself takes real time, both human and automated. Maintaining it all is an ongoing cost.

The commercial license and paid API tiers are how we recover those costs fairly: non-commercial developers can build for free, and commercial developers who profit from the data chip in to support the infrastructure they’re relying on.

At the same time, we don’t show ads on the site, and the API has a free tier. The goal is to keep barriers low and MARTA data transparent and accessible, while making sure the people building businesses on top of it help sustain the work.

How do notifications work? You can subscribe to email or browser push alerts for specific routes or stops without creating an account, just provide an email address or allow push notifications in your browser when prompted. You can unsubscribe anytime using the link in each email or through your browser’s notification settings.

Is my data safe? What do you collect? For the core site, we collect basic usage data and, if you use them, your saved favorites and notification opt-in details (like an email address or push token), none of which require an account. If you create a developer account, we also collect your email, password, and billing information for paid tiers. We don’t sell your personal information. Full details are in our Privacy Policy.

Do you show ads or track me? No, we don’t show ads. We may use privacy-respecting or standard analytics tools to understand site usage. Details on cookies and analytics are in our Privacy Policy.

I found a bug or incorrect data. How do I report it? Email [email protected] with what you saw and, if possible, the route/stop and time.

Is atltransit.live free? Yes, the core site (live map, arrivals, route maps, and service alerts) is free to use, with no account or payment required. Developer/API access is a separate, paid tier. See “Why do you charge for developer access?” above.

Do you have an app? Yes, a native app is planned for release. We’ll announce it on the site and through our alert channels when it’s available.

How is atltransit.live related to marta.fail? atltransit.live is the next iteration of the project that started as marta.fail, expanding from Bluesky alerts into a full live-tracking site. Both are operated by CFS.

Release history

August 8, 2026 — Rebrand, live stop pages, and a public data license

  • Relaunched marta.fail as ATL Transit Live, expanding beyond MARTA alerts into a full live-tracking site while keeping the original Bluesky alert accounts running.
  • Rebuilt stop pages with a live-updating arrival timeline and an on-time reliability breakdown for every route serving that stop.
  • Unified the route and rail-line maps onto one shared map component, for more consistent live vehicle tracking and stop markers across the site.
  • Made stop markers on route and rail maps more visible against the map background.
  • Made every public data table on the site sortable, with horizontal scrolling on narrow screens so wide tables no longer clip.
  • Published our Data License, covering non-commercial and commercial reuse of the data we publish.

July 29, 2026 — API and site updates

  • Completed the major refactor from marta.fail into ATL Transit Live, expanding the original alert service into a broader transit-data site with a separate, versioned developer API.
  • Completed the move to the documented /api/v1 developer API and aligned its behavior, examples, and interactive documentation.
  • Added easier browsing for longer current-incident and disrupted-route lists.
  • Made the reliability and alerts date range easier to understand and change, with the same control and spacing across every page that supports history.
  • Improved live bus maps with direction-aware markers, rider-facing destinations, speed, status, and update time.
  • Improved subscription checkout returns and added a helpful sitewide page for missing or outdated links.
  • Added the rewritten About page plus Terms of Service and Privacy Policy links.
  • Verified the published API operations against the implementation so developers receive the documented response shapes.
