This app allows users to flag when trains are crossing intersections and when trains have passed through. It provides a quick way for drivers to know if a train will block their path without having to wait at the intersection. The app could integrate with Google Maps to detect traffic congestion caused by train crossings and notify users. It would need to connect to local servers and switch to being fully server-sided. Long term, the app may be able to partner with railroad companies to receive direct notifications of upcoming train crossings.
