## What is Signalyst?

Signalyst connects drivers, cyclists, and pedestrians to transportation infrastructure. It improves travel efficiency by providing traffic light and crosswalk information, including time-to-green countdowns and advisory speeds. It improves travel safety by notifying users of potential vehicle and pedestrian conflicts. It runs in the background and uses Live Activities to provide real-time updates based on location.

Signalyst only supports specific regions in North America, starting with the City of Charleston, South Carolina.
