Verizon Edge Transportation Exchange Sample Client

The official onboarding resource for Verizon Edge Transportation Exchange. This sample client is designed to accelerate development by providing reference implementations which include a high-performance SAE J2735 codec.

What is Edge Transportation Exchange (ETX)?

Verizon Edge Transportation Exchange is a network vehicle-to-anything (Network V2X) solution that leverages the Verizon 5G infrastructure, mobile edge compute (MEC), and Hyper Precise Location (HPL) to enable near real-time data exchange between connected vehicles and transportation systems. It serves as an ecosystem foundation for intelligent transportation use cases, currently supporting vulnerable road user alerts, weather conditions, and traffic-signal information to improve safety and efficiency. Its virtual architecture eliminates the need for expensive physical roadside units, reducing costs for transportation agencies.
