SI Interface

Insight:

Facilitating large-scale deployment of C-ITS use cases requires communication between road users and roadside equipment independent of the equipment manufacturer.

Problem:

A standard interface for the exchange of C-ITS messages such as SPAT, MAP, CAM, SRM, and SSM between Traffic Light Controllers (TLCs) and the national intelligent TLC datahub was missing.

Solution:

The SI interface enables Traffic Light Controllers (TLCs), and other roadside equipment, to communicate with road users in a standardized way
