Use case 17 is dedicated to information related to receiving and publishing in real time the position of workers on the road when they present a risk to themselves or to drivers. This service includes the information generated by the Connected Vest.

This information can be sent to the DGT 3.0 platform either by IoT devices or by Apps that can be used to position these elements on the road. The platform has the functionality for the publication (sending) of information through a REST API. Both the publication and subscription functionality require different access certificates that must be requested and supplied by DGT 3.0. If these certificates have not already been requested, they should be requested from soporte@cmobility30.es.

Below are the URLs with which each functionality is accessed:
