V2I Safety
Application Description
- Red Light Violation Warning (RLVW)
- An application that broadcasts signal phase and timing (SPat) and other data to the in-vehicle device, allowing warnings for impending red light violations
- Curve Speed Warning (CSW)
- An application where alerts are provided to the driver who is approaching a curve at a speed that may be too high for safe travel through that curve.
- Stop Sign Gap Assist (SSGA)
- An application that utilizes traffic information broadcasting from roadside equipment to warn drivers of potential collisions at stop sign intersections
- Spot Weather Impact Warning (SWIW)
- An application that warns drivers of local hazardous weather conditions by relaying management center and other weather data to roadside equipment, which then re-broadcasts to nearby vehicles
- Reduced Speed/Work Zone Warning (RSWZ)
- An application that utilizes roadside equipment to broadcast alerts to drivers warning them to reduce speed, change lanes, or come to a stop within work zones
- Pedestrian in Signalized Crosswalk Warning (Transit)
- An application that warns transit bus operators when pedestrians, within the crosswalk of a signalized intersection, are in the intended path of the bus
