Abstract
A system that automatically communicates the event or potential event of a blocked railroad grade crossing to various users, including but not limited to emergency dispatchers and drivers, news media, traffic management systems, and the general public, specifically the location, time, and duration of the event or potential event. The system applies multiple technologies to detect the presence of activity on a rail line, transmits this detection data to a database, performs various analyses on the data, and communicates the status of grade crossings (blocked, potentially blocked, upcoming blockage, or clear) to assist various users with information to make more informed decisions.
