Message Exchange Platform and Mobile Device Application

The Vendor is required to provide a complete Network-Vehicle-to-Everything (V2X) Message Exchange Platform (MEP) and a mobile device application that sends and receives Society of Automotive Engineers (SAE) J2735 messages to and from the MEP. 
- The MEP shall utilize intelligent message distribution methods, such as geohashing, to efficiently determine which mobile device should receive specific messages based on their geographic location.
- The MEP shall seamlessly integrate with Connected Vehicle Acceleration Zone (CVAZ) system components, providing real-time access to traffic signal controller data and the ability to support signal priority and preemption requests from mobile devices and send vulnerable road user (VRU) notifications and position correction messages to mobile devices.
- Emergency Vehicle Preemption (EVP), Transit Signal Priority (TSP), Vulnerable Road Use (VRU) Safety, and Freight Signal Priority (FSP) V2X applications will be supported.
- EVP Intersections are located along major thoroughfares, which are generally spaced at one-mile increments within the regional street network.
- The application will also provide alerts to the vehicle operator when there is potential for a VRU to cross paths with the vehicle. 
- The application will receive infrastructure messages from the MEP, providing similar functionality as On-Board Unit (OBUs), for interactions with V2X infrastructure.
- Support shall be available Monday through Friday from 7:00 a.m. to 6:00 p.m. MST. Service shall be toll-free, live, English-speaking customer service telephone support.
- Provide regular system updates to ensure that the system software, including all third-party software, shall be the manufacturer’s “current” version.
