Make at‑grade crossings safer—without waiting years for overcrossings
U.S. rail systems connect our past and future, but busy city crossings pose serious risks to pedestrians and cyclists. Safety Digital Box (SDB) adds smart, event‑linked alerts—visual and multilingual audio—that help people clear the tracks in time.
Why not just build overcrossings?
They eliminate conflict but often cost millions and take years. SDB improves safety now—at a fraction of the cost.
At‑grade with AWS is the next best option
Layered alerts (lights, gates, alarms) provide reliable protection. SDB upgrades crossings that lack consistent warnings.
The problem at at‑grade crossings
A single hand signal isn’t enough—especially with distractions, complex layouts, and quiet, fast trains.
- Human factors: phones, traffic, mental stress, unclear track zones, and multi‑track confusion.
