AI Technical Summary
Existing technologies cannot dynamically publish information such as road restrictions, parking restrictions, and speed limits, which makes it inconvenient for autonomous vehicles to operate.
By generating restricted electronic zone information at the operating terminal, and having the server determine the associated RSU, the information is sent to the motion terminal within the coverage area via the RSU. The motion terminal then adjusts its driving behavior based on its actual location.
This enables traffic management departments to dynamically release road restriction information, allowing autonomous vehicles to stay informed about dynamic restrictions ahead, thus improving the driving experience and convenience.
