+## What is OpenV2X？
+
+OpenV2X is committed to providing an open source solution that processes the "roadside" open
+infrastructure of vehicle-road collaboration through "far-edge" computing power.
+
+In the "cloud-edge-device" three-layer architecture, OpenV2X focuses on the "far edge" (5G/6G base
+station side edge cloud computing), and does not involve the "near edge" (RSU industrial computer)
+part. In the "vehicle-road collaboration" framework, OpenV2X focuses on the "roadside" open
+infrastructure, and does not involve the "vehicle" part.
+
+OpenV2X provides the following capabilities:
+
+- Roadside equipment (including RSU, lidar, millimeter-wave radar, signal lights, cameras and so on)
+  management
+- Roadside data collection and analysis
+- Central cloud control platform information summary and display
+
+## Why need OpenV2X?
+
+Why do we need a "roadside collaboration" solution with the "vehicle intelligent driving" solution?
+
+Simple analogy: The car can drive in the dark, but it is safer with street lights. OpenV2X plays the
+role of "street light" in the overall solution of vehicle-road collaboration.
+
+## OpenV2X Vision and Goals
+
+The "Vision" of OpenV2X:
+
+- To improve the state of transportation in real life.
+- Reduce traffic jams and accidents by monitoring and analyzing roadside device data
+- Facing emergencies, accelerating traffic response and rescue capabilities
+
+The "goals" of OpenV2X:
+
+- A large number of practical and replicable deployment cases
+- Form a profitable, marketable business model (SaaS/Enterprise Edition)
+- Promote the formation of a good software and hardware ecosystem in the industry, adapt to the
+  southbound hardware management interface, provide a unified northbound API, and bring together
+  vehicle-road collaboration algorithms
