Create a service alert

When there's a disruption on your network, you can create service alerts to provide additional information for users. When you create service alerts, they’re added to your Transit feeds and are displayed on Google Maps.

About service alerts

With Google Transit, you can tell users about current or future service disruptions that may affect their trip with service alerts.

Service alerts can be published using GTFS Realtime feeds or they can be manually published in the Transit Data Sharing Portal.
