Concepts of Connected Vehicle Applications: Interface Lessons Learned from a Rail Crossing Implementation

Emerging connected vehicle (CV) technologies provide timely, advance warnings of roadway hazards to road users who may be incapable of perceiving them otherwise. Between 2012 and 2019, United States government transportation agencies deployed V2X Hub, an open platform supporting a broad set of transportation safety applications. This platform facilitates real-time data sharing between infrastructure, in-vehicle, or mobile devices to communicate hazards using Dedicated Short-Range Communications (DSRC). Armed with expertise gained in developing the technology, along with a renewed focus for the design of the in-vehicle safety system's Human-Machine Interface (HMI), the Rail Crossing Violation Warning (RCVW) research team evaluated practical driver use cases and extended the system capabilities to meet a broader set of safety goals.
