There are thousands of safety-related incidents each year across the globe at railway crossings. Of these, many involve vehicles that have low clearances. Others involve crossings where visibility and lines of sight are limited.
VisioStack's AXIS (Aerial Crossing Inspection System) inspection process uses off-the-shelf drone technology to improve risk assessment at crossings. Combined with a railway's existing crossing asset information, AXIS delivers automation including flight pre-planning, execution & collection, data transfer and generation of reports.
Crossing management stakeholders often struggle with having up-to-date, accurate information. Since forward-facing video is becoming commonplace in the industry we have a unique opportunity to constantly check for changing conditions at crossings and other assets. By applying Deep Learning models to forward-facing video, we can assess signage and lines of sight from the perspective of the locomotive.
Key assets to be inventoried include crossing gates, signage, and pavement markings. Conditions such as properly lowered gates, infringements, sign degradation can also be detected.
Our crossing management platform serves as a centralized repository for all crossing asset information and associated condition information. Configuration information can either be synchronized with external systems, or serve as the source on which condition data is populated.
Condition data can include signal malfunctions, gate malfunctions, ground clearance exceedences, broken panels, limited lines of sight, and insufficient or limited signage. As new condition data becomes available, the platform is able to expand and incorporate it into its overall risk assessment for the crossing.
